Description

200403096 玖、發明說明: (一) 發明所屬之技術領域 本發明係有關氣體淨化材,其爲了淨化家庭、事務所、 商店、工廠等室內空間、車輛車內空間等氣體所用者,再 詳言之,關於以理想的作爲消臭過濾等氣體淨化過濾材使 用的氣體淨化材及其製造方法。 (二) 先前技術 先前爲了淨化以家庭、事務所、工廠等爲首的種種室內 空間、車輛等車內空間等氣體,使用有種種的氣體淨化材 。使用氣體淨化材來淨化室內空間、車內空間等氣體之際 ’ 一般所利用方法係以過濾形態組裝氣體淨化材入空氣淸 淨機內,將空氣取入空氣淸淨機內,由於使空氣通過該過 濾器來去除浮遊在空氣中的灰塵等,同時使空氣接觸於載 持在過濾器的活性碳等粒狀吸附劑,吸住及/或分解存在 於空氣中作惡臭成分或者污染成分的酸性氣體、鹼性氣體 、有機物等來淨化空氣,由將所淨化的空氣再度吹出入室 內予以淨化室內的方法。以此系統的氣體淨化法,除空氣 淸淨機以外,也有取進空氣入冷氣機(空氣調節機)等,及 冷卻或將所暖和氣體的吹入室內之際亦同樣可以適用者。 又淨化車輛等車內空間空氣之際亦採取有同樣的方法。 作爲使用於該等氣體淨化的氣體淨化材之過濾材,係利 用黏接劑、熱熔樹脂等之黏結力,將活性碳等粒狀吸附劑 固定在爲通氣性基材的織物、織布、不織布或網等通氣性 片者’或於通氣性片作成時預先予以含有粒狀吸附劑在片 -5- 200403096 內者’或於2枚通氣性片間夾入粒狀吸附劑者等有種種者 爲眾所知。此外,在蜂巢狀六角柱之部分塡塞九形狀活性 碳者’或由於組合波狀通氣性片及平面狀通氣性片形成的 三角柱部分塡塞九形狀活性碳者亦爲所周知。 具體的例示該等內的幾個時,日本國特開平3-113213 號公報’揭示有由於黏結粒狀吸附劑的粒狀活性碳在網狀 聚氨酯泡沬,形成片狀過濾器,又特開平4-60320號公報 ’揭示有混入作脫臭劑的活性碳於合成樹脂製之過濾網, 或以黏合劑的黏結作載持形成片狀過濾器。又如在特開平 11-57467號公報或特開平10-165731號公報,揭示有由熱 熔樹脂所成連結部及樹脂凝聚部構成的網表面撒布脫臭粉 粒體,藉由樹脂凝聚部黏結脫臭粉粒體,同樣在其他表面 藉由樹脂凝聚部黏結其他脫臭粉粒體,疊層2種粉粒體的 方法,或將活性碳與粉體黏合劑一起撒布於通氣性不織布 ,其上重疊不織布,由於以熱輥子加熱、加工來黏結活性 碳的方法。 可是該等先前之氣體淨化材,並不能同時良好地吸附以 及去除通過氣體淨化材的空氣,及與氣體淨化材接觸的空 氣中之特定氣體成分,乃不足夠作爲氣體淨化材者。亦即 ,於上述黏結粒狀活性碳在網狀聚氨酯泡沬,或添加脫臭 劑在合成樹脂過濾網的方法,係塗覆黏合劑於聚氨酯泡沬 或過濾網,該黏合劑上予以撒布按壓粒狀吸附劑,採取蒸 發乾燥含在黏合劑中的溶劑方法。可是高濃度之黏合劑的 黏度高,如此的高黏度黏合劑係困難於均勻地塗覆。一方 -6- 200403096 面塗覆應予降黏度而使溶劑之量多作成爲稀薄黏合劑時, 有無法避免降低黏合力,同時僅能黏附比例於所塗覆黏合 劑量的問題。再者,使用多量黏合劑則活性碳粒子表面會 以黏合劑所被覆,指摘有降下臭氣等氣體成分之吸附性缺 點’困難於欲將大量的良好吸附性能之粒狀吸附劑黏附在 片上。又使用大量的黏合劑時,有通氣阻力變高,對比較 粗的粉麈,例如花粉、砂塵、尖峰粉塵等在早期容易生起 堵塞的問題。 一方面以熱熔樹脂構成的不織布撒布脫臭粉粒體來疊層 脫臭粉粒體的方法,或在通氣性不織布之間夾住活性碳及 黏合劑來黏結活性碳的方法,係以一次製程並不能黏結大 量粒狀吸附粒子,又於通氣性不織布之間夾住活性碳粒子 及黏合劑的方法,在粒狀吸附劑之層上下有纖維,由通過 氣體中吸附或去除特定之氣體狀成分時並無問題,但接觸 氣體於吸附劑來去除特定之氣體狀成分時,吸附劑不能直 接接觸於作接觸的氣體,再者,有不能獲得充分地每一單 位體積之氣體吸附量或氣體去除量問題。 此外,與單纖維混合粒狀吸附劑滲入的技術從先前就爲 周知,在日本國特開平2000-24426號公報等揭示有含有 粒狀活性碳、支持纖維、及水膨潤性之黏合性纖維的水系 淤漿所成,粒狀活性碳含有片之製造方法。於使粒狀吸附 劑與單纖維混合滲入技術,在水系中予以懸浮粒狀吸附劑 及單纖維形成淤漿狀,所以難於片化大的吸附劑,不但是 限制了可使用的粒狀吸附劑,又不能滲入大量的粒狀吸附 -7- 200403096 劑’再於片形成後亦需要乾燥含大量水份的粒狀吸附劑, 將粒狀吸附劑與單纖維混合來滲入方法,不一定能稱爲經 濟的方法者。 (三)發明內容 [發明欲解決的問題] 近年來,提高了對於家庭、辦公室等室內、車輛等車內 的生活臭關心,不僅是要求更加的吸附及去除氣體中臭氣 氣體成分’並由廢氣氣體等增大酸性氣體在大氣中濃度等 ’以半導體製造時氣體的淸淨化或在美術館等的保護繪畫 、陶器類爲目的,變成要求吸附或去除氣體中之特定氣體 ,對應於此亦要求更優越的過濾材。爲了改善如此的過濾 材之特性,希望同時改質粒狀吸附劑並增大粒狀吸附劑之 充塡容量。 又上所述在先前所知的表面黏附有氣體通過效率以及接 觸效率同時良好的粒狀吸附劑過濾材,係粒狀吸附劑對過 濾材的增大充塡容量困難,又上所述以2層纖維層來夾持 粒狀吸附劑方法,雖予增大粒狀吸附劑之充塡容量,能夠 照原樣以片材形態來使用,但欲實行氣體淨化時,一般的 係折疊片狀過濾材在一定體積內予以裝配,增大一定體積 中的過濾面積,以一定體積中增大氣體吸附量以及氣體去 除量,同時予以謀求增大氣體的淨化處理量。 以如此的目的片狀過濾材係大部分作爲打褶加工或泡沬 條紋加工,但由2層纖維層來夾住粒狀吸附劑方法謀求增 大粒狀吸附劑之充塡容量時,在打褶加工或泡沬條紋加工 -8- 200403096 片狀過濾材之際有粒狀吸附劑層破裂、剝離的問題。欲解 決該粒狀吸附層的破裂或剝離問題予以增大黏合劑量時’ 因彼此粒狀吸附劑間僅爲點黏附而已,所以打褶加工時不 能得到所需要的韌性或強度,又由於大量的黏合劑,覆蓋 了粒狀吸附劑之表面阻礙了粒狀吸附劑本來所具有吸附性 能,應予淨化的氣體就不與粒狀吸附劑接觸而通過過濾材 ,或由於過濾材表面的不存在粒狀吸附劑,亦有應予淨化 氣體不會與過濾材的粒狀吸附劑接觸之根本的問題。 本發明,係爲於黏結粒狀吸附劑於通氣性基材的織物、 織布、不織布或網等通氣性片時,提供氣體淨化材,其無 降低通氣性的增大粒狀吸附劑之充塡容量,在實際使用時 爲良好的打褶加工特性,同時增大欲淨化的氣體通過效率 '接觸效率,同時能形成爲增大每單位體積的氣體吸附量 或氣體去除量的過濾材爲目的。 [解決問題的手段] 本發明者係進行銳意檢討結果,發現藉由使通氣性基材 表面起毛,將粒狀吸附劑黏結在該起毛面,則能得到達成 上述目的之氣體淨化材,而完成本發明者。 亦即,本發明係提供氣體淨化材,其特徵爲將粒狀吸附 劑黏結於通氣性基材的起毛面而成者。 又,本發明係提供氣體淨化材之製造方法,其特徵爲藉 由使通氣性基材起毛後,撒布粒狀吸附劑於該起毛面及加 熱’將粒狀吸附劑黏結在起毛面。 (四)實施方式 冬 200403096 以下詳細說明,構成本發明氣體淨化材的材料,及氣體 淨化材的製造方法。 首先’作爲製造本發明氣體淨化材的方法,可列舉如上

又氨、胺類、吡啶等鹼性氣體用者列舉燐酸、 、蘋果酸、檸檬酸、抗壞血酸等有機酸、無機 添附劑,並非爲粒狀吸附劑,亦可以含浸在通 預先含有在基材。 、高嶺土、 狀吸附劑亦 分解的氧化 以。該等催 發明,係來 吸附劑者。 也可以。又 爲理想。於 氧化鋁、沸 狀吸附劑表 爲黏附在添 SOx、乙酸 鈉、碳酸氫 驗金屬氫氧 胺、P-茴香 聚乙烯亞胺 鹽類、哌系 脲氨基氫氯 可以列舉。 硫酸、硝酸 酸。尙該等 氣性基材或 -11- 200403096 於本發明的氣體淨化材,有粒狀吸附劑之平均粒徑大時 過濾器會變大就困難於打褶加工,相反的過小時壓力損失 變大,同時容易從起毛的不織布流出於外部的問題,故1 〇 〇 〜ΙΟΟΟμιη程度爲理想。 又撒布粒狀吸附劑於起毛的通氣性基材方法,係只要是 先前所知的撒布方法其任何者即可。並不是加以限定本發 明者,欲均勻地撒布粒狀吸附劑在起毛的不織布等通氣性 基材方法,列舉使用先前作爲粉體撒布裝置所知的輥子式 撒布機方法爲理想的方法。尙,此輥子式撒布機,由漏斗 ,用來儲存粉體;旋轉體,在該漏斗下部支撐成能夠旋轉 ’外周部具有收容粉體的收容槽;以及刮削器,配置在該 旋轉體外周面的近接位置用來規定該漏斗的粉體落下供給 所成。 作爲用於本發明的通氣性基材,雖可列舉紙、織物、織 布、不織布等,但從經濟性考量理想爲紙、不織布,特別 是在表背兩面容易加以起毛的紙、不織布爲理想。又於不 織布係在黏結粒狀吸附劑上’以含熱熔融聚合物熱熔融纖 維構成的不織布爲理想。欲由含熱熔融纖維的纖維構成通 氣性基材時,熱熔融纖維含有量係5 〇%以上,理想爲7〇% 以上,更理想爲8 0 °/。以上,有1 〇 〇 %也可以。 所謂熱熔融聚合物,係由加熱作熔融含有熱熔融成分的 聚合物,所謂熱熔融纖維,係指由加熱熔融含有聚合物成 分的纖維,由熱熔融’與相鄰纖維熔融的纖維。作爲熱熔 融成分,例如可列舉聚乙烯、改質聚乙烯、共聚聚酯、共 200403096 聚尼龍、乙烯-醋酸乙烯酯共聚物等。 熱熔融纖維之剖面形狀,包含圓剖面、矩形剖面,任何 的剖面形狀都可以。又熱熔融纖維亦可爲單一成分的樹脂 ’自複數成分所成者亦可以。作爲自複數成分熱熔融纖維 可列舉具並置(side by side)構造或皮芯(sheath-core)構 造的剖面形狀。例如具皮芯構造纖維,係使用皮部側熔融 溫度低於芯部的樹脂。作爲如此的組合,例如可列舉以皮 爲聚乙烯或乙烯-醋酸乙烯酯共聚物、芯爲聚丙烯的組合 ,或皮以低熔融溫度的共聚聚酯、芯爲聚對苯二甲酸乙二 醇酯的組合等。如此組合不同熔融溫度的樹脂,由於使纖 維表面的熔融溫度比內部爲低纖維,於規定溫度僅熔融表 面部分,可以照原樣保持內部纖維形狀者。本發明使用的 熱熔融纖維的纖度係1〜1 0 0丹尼,理想係3〜5 0丹尼、 更理想爲5〜30丹尼。 本發明欲由含有熱熔融纖維的纖維形成通氣性基材之際 ’作爲與熱熔融纖維一起使用的熱熔融纖維以之纖維,任 何爲較熱熔融纖維高熔融溫度的纖維都可以。作爲如此的 纖維’例如除聚酯、聚丙烯腈、聚醯胺、聚丙烯等聚烯烴 的合成纖維外,亦可爲棉絨纖維、木棉、麻等天然纖維、 木材漿料、嫘縈等半合成樹脂纖維、玻璃纖維等。理想爲 嫘縈、聚酯、聚烯烴、聚醯胺等纖維。熱熔融纖維以外之 纖維纖度乃與熱熔融纖維同樣,爲1〜1 00丹尼、理想爲 3〜50丹尼、更理想爲5〜30丹尼。 作爲粒狀吸附劑對起毛通氣性基材面的固定化方法,係 200403096 以包含上述熱熔融聚合物在熱熔融纖維的熱熔融時黏附力 ,固定化粒狀吸附劑的方法以外,將熱熔融聚合物粉粒體 與粒狀吸附劑一起撒布,予以加熱熔融熱熔融聚合物,固 定粒狀吸附劑於起毛的通氣性基材方法,再者,可列舉倂 用該等方法的方法。作爲加熱方法係使用紅外線等,亦可 不加以壓力於起毛面狀態來加熱,撒布粒狀吸附劑起起毛 面後,送進經加熱的一對帶間,使其由於通過因應必要的 加壓下實行加熱也可以。 作爲上述熱熔融聚合物之粉粒體,可列舉熱可塑性聚醯 胺系樹脂、熱可塑性聚酯樹脂、熱可塑性聚氨酯樹脂、聚 烯烴樹脂、乙烯·醋酸乙烯酯共聚物、乙烯-醋酸乙烯酯共 聚物之鹼化物、丙烯酸共聚物、乙烯-丙烯酸乙酯共聚物 、乙烯-丙烯酸共聚物、離子型樹脂(乙烯-甲基丙烯酸共聚 物附加金屬的感熱性樹脂)等聚烯烴變性樹脂、及該等2 種以上之複合物等熱熔樹脂。又,熱熔融聚合物之粉粒狀 融點,通常與構成通氣性基材的該熱熔融纖維融點相等或 其以下,又比較非熱熔融纖維的纖維作低融點者。欲黏結 粒狀吸附劑於通氣性基材起毛面之際,係黏結粒狀吸附劑 在通氣性基材或起毛的纖維,但舉起毛的纖維以互相不黏 結爲理想形態,設定上述融點成爲如此的條件即可。當然 ,不會予以阻礙通氣性,則起毛的彼此纖維間成在黏結狀 態亦可以。 熱熔樹脂之使用量,根據所使用粒狀吸附劑重量作1 % 〜2 0 0%爲理想。少於1 %則變成不夠黏合,使粒狀吸附劑 -14- 200403096 不能黏結在起毛的不織布等通氣性基材,容易自通氣性基 材脫落,一方面多於2 0 0 %時變成由熱熔樹脂覆蓋大部分 粒狀吸附劑表面’形成爲損及消臭性能,同時在熔融時由 通乘^性基材吸收熱谷樹脂’損及基材通氣性,有時也會呈 現污?狀的外觀。 作爲熱熔樹脂的平均粒徑,係小於粒狀吸附劑之粒徑爲 理想,1 0〜1 0 0 0 μηι爲理想。熱熔樹脂之平均粒狀大於 ΙΟΟΟμχη時就不能獲得充分黏合力,小於10μιη時成爲增 高通氣阻力的原因。 因賦予上述通氣性基材或氣體淨化材,其他抗菌性、抗 霉性、抗過濾性病原體性、難燃性功能,所以亦可預先混 入、或混合抗菌劑、抗霉劑、抗過濾性病原體性、難燃性 、功能性藥劑等在通氣性基材本身或熱熔樹脂。又該等藥 劑’亦可以不損及其本來性能方法及量、或黏結於粒狀吸 附劑,亦可以塗覆在通氣性基材來黏附。再於通氣性基材 ,亦可賦予上述以外的功能性,例如駐極體性。 本發明之氣體淨化材,用於空氣淸淨機、空氣調和機等 過濾、材至爲理想。本發明之氣體淨化材爲平板狀,或成形 打褶狀或波形作過濾材,例如由於使空氣通過氣體淨化材 面而能實行空氣淨化。又泡沫條紋加工本發明的氣體淨化 材,與氣體淨化材平行方向以設置多數通風路地成形爲蜂 巢狀,亦可以獲得氣體淨化過濾器。特別是由於起毛該基 材之表背兩面,黏結該粒狀吸附劑於表背兩面,能獲得具 有低壓力損失,具每一單位體積之接觸氣體去除效率更高 200403096 的空氣淨化過濾器。 尙蜂巢之製造法雖有種種爲周知,但其一係利用瓦楞紙 者。如周知的瓦楞紙,係具平的原紙的線性及段成形爲波 形的原紙中芯,使用黏合劑疊層黏合的構成,使用稱謂起 波形或壓波形機裝置所製造。將該瓦楞紙以疊層多段或卷 繞爲輥子狀態予以切割,則能獲得作目的的蜂巢構造體。 (例如,參照日本國實開昭57- 1 1 9724號公報之第1〜第4 圖)於本發明,也可與此同樣方法製造蜂巢構造。 又本發明氣體淨化材,功能性片亦可爲,例如持有功能 性的不織布,作疊層於通氣性基材等再予附加者亦可以。 設功能性.片的面,係不管是黏結粒狀吸附劑於起毛面的面 亦可,雖起毛但爲未黏結粒狀吸附劑的面,未起毛的面都 可以。可是在未起毛的通氣性基材因也能使其持有同樣的 功能,故設置粒狀吸附劑在黏結的面爲理想。作爲設置功 能性片於通氣性基材方法,係貼上利用基材片中之熱熔融 聚合物的功能性片,另外使用熱熔樹脂粉粒體等的黏合等 ’可列舉任意的方法。 作爲上述功能性片,例如可列舉具低壓力損失且高捕集 效率的駐極體熔融吹製不織布或賦予抗菌劑或抗霉劑的不 織布等。駐極體熔融吹製不織布,可以尼龍、聚乙烯、聚 丙燒等形成,但以高駐極體效果的聚烯烴系纖維爲理想。 以下舉實施例具體的說明本發明,但本發明並不限定於 本實施例者。 實施例1 200403096 作爲通氣性基材’由芯爲熔融溫度240 °C的聚酯,護套 爲熔融溫度1 3 2 °C之聚乙烯所成’纖度以2的熱熔融纖維 構成,以悠你積加(Unichica)(股)公司製紡黏(sPun-bond) 不織布的40g/m2品,通過附刷子的輥子,撒布調整爲20 網目以上42網目以下的可樂麗(Kuraray)化學(股)公司製 粒狀活性碳成2 0 0 g/m2,將此夾持在1對無次元帶,在150 °C加熱加壓後,冷卻獲得氣體淨化材。 所獲得氣體淨化材之單位面積重量(日本織物單位面積 重量)係2 3 5 g/m2,粒狀活性碳之黏結量係195 g/m2。又從 獲得的氣體淨化材並無落下粒狀活性碳,予以實行彎曲試 驗結果無破壞活性碳層,顯示了良好的打褶特性。 使用獲得 50ιηχηφ的氣體淨化材,在室溫中,以面速度 10cm/秒通過調整爲60ppm濃度的濕度50%之甲苯氣體, 以氣體技術(Gas tech)(股)公司製甲苯檢測管測定濃度結 果,50%時之破壞過程時間係成40分,獲得良好的壽命時 間。 比較例1 除了在實施例1使用的通氣性基材不起毛狀況外,同樣 與實施例1獲得氣體淨化材。獲得的氣體淨化材之單位面 積重量(日本織物單位面積重量)爲1 40g/m2,黏結粒狀活

technical field to which the invention belongs The present invention relates to gas purification materials, which are used for purifying gases such as indoor spaces such as homes, offices, shops, factories, and interior spaces of vehicles. The present invention relates to a gas purification material which is preferably used as a gas purification filter material such as a deodorizing filter, and a method for manufacturing the same. (II) Prior technology In the past, various kinds of gas purification materials were used in order to purify various indoor spaces such as homes, offices, factories, etc., and interior spaces of vehicles. When using a gas purification material to purify gases such as indoor space and car interior space, the general method used is to assemble the gas purification material into the air purifier in the form of a filter, and take the air into the air purifier. This filter is used to remove dust floating in the air, and at the same time, contact the air with granular adsorbents such as activated carbon carried on the filter, and absorb and / or decompose the acidity that is present in the air as a malodorous or polluting component. A method of purifying air by using a gas, an alkaline gas, an organic substance, or the like, and blowing the purified air into the room again to purify the room. In addition to air purifiers, the system's gas purification method can also be applied to take in air into an air conditioner (air conditioner), etc., and to cool or blow warm air into the room. The same method is used to purify the air in the interior space of vehicles. As a filter material for gas purification materials used for such gas purification, a granular adsorbent such as activated carbon is fixed to a fabric, a woven fabric, or the like, which is a breathable substrate, by using the adhesive force of an adhesive, a hot-melt resin, or the like. There are various types of air-permeable sheets such as non-woven fabrics or nets, or those containing a particulate adsorbent in advance when the air-permeable sheet is prepared, or those who sandwich a granular adsorbent between two air-permeable sheets. Is well known. In addition, it is also known to condense nine-shaped activated carbon on a part of a honeycomb-shaped hexagonal column 'or a triangular column formed by combining a wave-shaped air-permeable sheet and a planar air-permeable sheet to partially enclose a nine-shaped activated carbon. When exemplifying a few of these, Japanese Unexamined Patent Publication No. 3-113213 discloses that granular activated carbon that has adhered to a granular adsorbent is foamed in a mesh polyurethane to form a sheet filter. Gazette No. 4-60320 discloses that a filter made of synthetic resin is mixed with activated carbon as a deodorant, or a sheet filter is formed by being supported by a binder. Another example is disclosed in Japanese Patent Application Laid-Open No. 11-57467 or Japanese Patent Application Laid-Open No. 10-165731. Deodorized powder and granules are scattered on the surface of a mesh composed of a connecting portion made of a hot-melt resin and a resin agglomerating portion, and the resin agglomerates to stick together Deodorized powder and granules are similarly bonded with other deodorized powders and granules on the other surface by resin agglomerates, and two kinds of powders and granules are laminated, or activated carbon and powder binder are sprayed together on an air-permeable nonwoven fabric. Non-woven fabrics are stacked on top of each other, which is a method of bonding activated carbon by heating and processing with a hot roller. However, these previous gas purification materials cannot simultaneously adsorb and remove the air passing through the gas purification materials and certain gas components in the air in contact with the gas purification materials, which are not enough as gas purification materials. That is, the method of foaming the granular activated carbon in a mesh polyurethane or adding a deodorant to a synthetic resin filter is to apply a binder to the polyurethane foam or the filter, and spray the pressure on the adhesive. For granular adsorbents, the solvent contained in the binder is evaporated and dried. However, high-concentration adhesives have high viscosity, and such high-viscosity adhesives are difficult to apply uniformly. One side -6- 200403096 When the top coat should be reduced in viscosity and the amount of solvent used as a thin adhesive, there is a problem that the reduction of the adhesive force cannot be avoided, and at the same time, it can only adhere to the proportion of the applied adhesive amount. Furthermore, if a large amount of a binder is used, the surface of the activated carbon particles will be covered with a binder, and it is difficult to attach a large amount of a granular adsorbent having a good adsorption performance to the sheet because of the lack of adsorption of gas components such as odor reduction. When a large amount of adhesive is used, there is a problem that the ventilation resistance becomes high, and it is easy to cause clogging of relatively coarse powdery powder such as pollen, sand dust, and spike dust at an early stage. On the one hand, the method of laminating the deodorized powder and granular material with a non-woven cloth made of a hot-melt resin, or the method of sandwiching activated carbon and a binder between air-permeable nonwoven fabrics to bond the activated carbon is performed once. The process cannot adhere a large number of granular adsorbed particles, and the method of sandwiching activated carbon particles and an adhesive between air-permeable nonwoven fabrics. There are fibers above and below the layer of the granular adsorbent, and the specific gas is adsorbed or removed by passing gas. There is no problem in the composition, but when contacting the gas with the adsorbent to remove a specific gaseous component, the adsorbent cannot directly contact the contacting gas. Furthermore, it is not possible to obtain a sufficient gas adsorption amount or gas per unit volume. Removal issues. In addition, the technique of infiltrating a particulate adsorbent with a single fiber is known from the past, and Japanese Unexamined Patent Publication No. 2000-24426 and the like disclose a granular fiber containing granular activated carbon, supporting fibers, and water-swellable adhesive fibers. Method for producing granular activated carbon-containing tablets made from aqueous slurry. For the mixed infiltration technology of granular adsorbent and single fiber, the granular adsorbent and single fiber are suspended in the water system to form a slurry, so it is difficult to form a large adsorbent, which not only limits the available granular adsorbent. Can not infiltrate a large amount of granular adsorption-7- 200403096 Agent 'After the tablet is formed, it is also necessary to dry the granular adsorbent containing a large amount of water. The method of mixing the granular adsorbent with single fibers to infiltrate may not be called For the economic method. (3) Summary of the Invention [Problems to be Solved by the Invention] In recent years, concerns about living odors in homes, offices, indoors, and vehicles have increased, not only to require more adsorption and removal of odorous gas components in the gas. Increasing the concentration of acid gas in the atmosphere, such as exhaust gas, is used to purify the gas during semiconductor manufacturing or to protect paintings and pottery in art museums. It becomes a specific gas that requires adsorption or removal of gas. Better filter media. In order to improve the characteristics of such a filter material, it is desirable to simultaneously change the particle adsorbent and increase the capacity of the particulate adsorbent. As mentioned above, a granular adsorbent filter material with good gas passing efficiency and good contact efficiency is adhered to the previously known surface. It is difficult to increase the capacity of the particulate adsorbent to increase the capacity of the filter material. The method of sandwiching the granular adsorbent layer by layer of fiber layer can increase the charge capacity of the granular adsorbent and can be used in the form of a sheet as it is. However, when gas purification is to be implemented, a general folded sheet filter Assemble within a certain volume, increase the filtering area in a certain volume, increase the amount of gas adsorption and gas removal in a certain volume, and seek to increase the amount of gas purification treatment. For this purpose, the sheet filter material is mostly used for pleating or foam stripe processing. However, when the granular adsorbent is sandwiched by two fiber layers to increase the filling capacity of the granular adsorbent, pleating is performed. Processing or foam stripe processing-8-200403096 When the sheet-shaped filter material is broken, the granular adsorbent layer is broken and peeled off. To solve the problem of cracking or peeling of the granular adsorbent layer and increase the adhesive amount, 'the granular adsorbents only adhere to each other. Therefore, the required toughness or strength cannot be obtained during pleating processing. Adhesive, covering the surface of the granular adsorbent, hinders the original adsorption performance of the granular adsorbent, and the gas to be purified will not contact the granular adsorbent and pass through the filter material, or because no particles exist on the surface of the filter material It also has the fundamental problem that the purified gas should not contact the granular adsorbent of the filter material. The invention provides a gas purification material when a granular adsorbent is bonded to an air-permeable fabric such as a fabric, a woven fabric, a non-woven fabric, or a net, and the gas-purifying material is provided without reducing the permeability of the granular adsorbent. The capacity is a good pleating processing characteristic in actual use, while increasing the gas passing efficiency to be purified, the contact efficiency, and at the same time, it can be formed as a filter material to increase the gas adsorption amount or gas removal amount per unit volume. [Means for Solving the Problem] The inventor conducted an intensive review and found that by raising the surface of the air-permeable substrate and bonding the granular adsorbent to the raised surface, a gas purification material that achieves the above-mentioned objective can be obtained and completed. The inventor. That is, the present invention provides a gas purification material characterized in that a particulate adsorbent is adhered to a raised surface of an air-permeable substrate. The present invention also provides a method for producing a gas purification material, which is characterized in that, after raising the air-permeable substrate, a granular adsorbent is sprayed on the raised surface and heated 'to adhere the granular adsorbent to the raised surface. (4) Embodiment Winter 200403096 The materials constituting the gas purification material of the present invention and the method for manufacturing the gas purification material will be described in detail below. First, as the method for producing the gas purification material of the present invention, the method described above can be enumerated. More specifically, after the surface of an air-permeable substrate, such as a fleece fabric, woven fabric, non-woven fabric, or net, is spread, a granular adsorbent is sprayed on the raised surface to bind a large amount of granular adsorbent with a binder, thereby, It can form the gas purification material of this invention. This method is merely a representative method for obtaining the gas purification material method of the present invention, and the method for manufacturing the gas purification material of the present invention is not limited to this method, but this method is exemplified below to explain the manufacturing of the gas purification material of the present invention in detail. Method and the constituent materials of the gas purification material of the present invention. First, it is a raising method of an air-permeable substrate when the gas purification material of the present invention is obtained. However, this method may be any known method. For example, the raising method may be roughened by crimping a roller equipped with sandpaper. The method of processing the emery fuzzing, the method of fuzzing the clothing that touches the cloth with a large number of fine needles, and the method of fuzzing with a needle crochet. Among these, the method of raising the sheet by raising it between the drums of numerous needles or brushes for grasping the surface, which is ideal, is mentioned. The fluffing system may be used only on one side of the air-permeable substrate of the gas purification material, and if necessary, may be used for raising the two sides of the air-permeable substrate. If you want to apply hair on both sides, you can also use the method of raising both sides at once, or the method of raising one side and raising the other side. The particulate adsorbent used for adsorbing gaseous components such as acid gases, alkaline gases, and organic substances for reasons such as malodor is also exemplified by iron, manganese, copper, aluminum, magnesium, zinc, nickel, cobalt, platinum, Gold-10-200403096 of palladium'ruthenium, rhodium and the like are monomers, such metal oxides or metal chlorides, zeolite sepiolite, silica gel, activated carbon, and the like. Furthermore, the particles of the present invention can be acid gas, alkaline gas, organic substances, etc. as catalytic titanium, phthalocyanine, platinum and other powder particles, that is, the catalytic particles can also be converted into particles. However, the particles do not have the ability to adsorb the above substances. The catalytic particles exhibiting the adsorption effect are also included in the granular adsorbent of the present invention. The particulate adsorbent can also be used alone. If two or more of these granular adsorbents are used, those with a large surface area are considered to be adsorbable. Examples of the particulate adsorbent include silicone, activated stone, and catalytic particles. The granular adsorbent used in the present invention is a chemical deodorizing agent adhered to the above-mentioned particles. For example, carbon may be added. As a carbon-adsorbed chemical adsorbent, for example, for acid gases such as aldehydes, NOx, and the like, metal carbonates such as potassium carbonate, potassium bicarbonate, and sodium carbonate, sodium hydroxide, potassium hydroxide, and the like, ethanolamine, 1,6-hexanediamine, methylamine, piperazine, aniline, sulfanilic acid, aminobenzoic acid and other amine compounds and their salts, and imine diethanol and other imine compounds and their compounds and their salts , L-arginine, methylamine hydrochloride, compounds, hydrazine, hydroquinone, hydroxylamine sulfate, permanganate and other basic gases such as ammonia, amines, pyridine, etc. Organic acids and inorganic additives such as citric acid and ascorbic acid are not granular adsorbents, and may be impregnated in advance and contained in the substrate. , Kaolin, and sorbents also decompose and oxidize. These urging inventions are those of adsorbents. Yes. And ideal. In the table of alumina and boiling sorbent, SOx, sodium acetate, hydrogen carbonate, metal hydroxide, P-anise, polyethyleneimine salts, and piperidine urea aminohydrochloride are listed for adhesion. Sulfuric acid, nitric acid.尙 For such gas-based substrates or -11-200403096 in the gas purification material of the present invention, when the average particle diameter of the granular adsorbent is large, the filter becomes larger, which makes it difficult to perform pleating processing. On the contrary, the pressure loss becomes too small. It is large, and it is easy to flow out of the fluffed non-woven fabric to the outside. Therefore, a degree of 100 to 100 μm is desirable. The method of spraying a particulate adsorbent onto the fluffy air-permeable substrate may be any of the previously known spraying methods. The present invention is not limited to this method, and a method of uniformly spreading the air-permeable base material such as a fuzzed nonwoven fabric with a particulate adsorbent is preferably a roll type spreader method known as a powder spreading device. Alas, this roller-type spreader is provided with a funnel for storing powder; a rotating body is supported at the lower part of the funnel so as to be capable of rotating; a storage groove for containing powder is provided on the outer periphery; and a scraper is arranged on the outer peripheral surface of the rotating body The close position is used to define the powder supply of the funnel. Examples of the air-permeable substrate used in the present invention include paper, woven fabric, woven fabric, and non-woven fabric. However, from the viewpoint of economical efficiency, paper and non-woven fabric are preferred, and especially paper and non-woven fabric that are easily fuzzed on the front and back sides are preferred. . The non-woven fabric is preferably bonded to the granular adsorbent. The non-woven fabric is composed of a hot-melt polymer containing hot-melt fibers. When it is desired to form the air-permeable substrate from fibers containing hot-melt fibers, the content of the hot-melt fibers is 50% or more, preferably 70% or more, and more preferably 80 ° /. Above, 100% is also acceptable. The hot-melt polymer refers to a polymer containing a hot-melt component by heating, and the hot-melt fiber refers to a fiber containing a polymer component by heat-melting, and a fiber fused to an adjacent fiber by hot-melt. Examples of the hot-melt component include polyethylene, modified polyethylene, copolyester, 200403096 polynylon, and ethylene-vinyl acetate copolymer. The cross-sectional shape of the hot-melt fiber includes a circular cross-section and a rectangular cross-section. Any cross-sectional shape is acceptable. The hot-melt fiber may be a single-component resin ′ or a composite of a plurality of components. Examples of the self-plurality hot-melt fiber include a cross-sectional shape having a side by side structure or a sheath-core structure. For example, a fiber with a sheath-core structure uses a resin having a melting temperature lower than that of the core on the skin side. Examples of such a combination include a combination of a polyethylene or ethylene-vinyl acetate copolymer as the sheath and a polypropylene as the core, or a copolyester with a low melting temperature as the sheath and a polyethylene terephthalate as the core. Ester combinations, etc. By combining resins having different melting temperatures in this way, since the melting temperature of the fiber surface is lower than that of the inside fiber, only the surface portion is melted at a predetermined temperature, and the shape of the internal fiber can be maintained as it is. The fineness of the hot-melt fiber used in the present invention is 1 to 100 denier, ideally 3 to 50 denier, and more preferably 5 to 30 denier. When the present invention intends to form an air-permeable substrate from fibers containing hot-melt fibers, as the fibers of the hot-melt fibers used with the hot-melt fibers, any fiber having a higher melting temperature than the hot-melt fibers may be used. Examples of such fibers include synthetic fibers such as polyester, polyacrylonitrile, polyamide, and polypropylene, as well as natural fibers such as linter fibers, kapok, and hemp, wood pulp, and hemp. Synthetic resin fiber, glass fiber, etc. It is ideal for fibers such as rhenium, polyester, polyolefin, and polyamide. The fineness of the fibers other than the hot-melt fiber is 1 to 100 deniers, preferably 3 to 50 deniers, and more preferably 5 to 30 deniers. As a method for fixing the particulate adsorbent to the fluffy air-permeable substrate surface, the system 200403096 includes a method for fixing the particulate adsorbent by including the adhesive force of the above-mentioned hot-melt polymer during the heat-melting of the hot-melt fiber, and heat-melting it. The method of spreading the polymer powder and granular material together with the granular adsorbent, heating and melting the hot-melt polymer, and fixing the granular adsorbent to the fluffy air-permeable substrate, and a method using these methods may be mentioned. As the heating method, infrared rays or the like can be used to heat the raised surface without applying pressure. After spraying the raised surface of the granular adsorbent, it is sent to a heated pair of belts, which is carried out by applying the necessary pressure. Heating is also possible. Examples of the powder and granules of the hot-melt polymer include thermoplastic polyamide resins, thermoplastic polyester resins, thermoplastic polyurethane resins, polyolefin resins, ethylene-vinyl acetate copolymers, and ethylene-vinyl acetate copolymers. Compounds such as alkali compounds, acrylic copolymers, ethylene-ethyl acrylate copolymers, ethylene-acrylic acid copolymers, ionic resins (thermosensitive resins with ethylene-methacrylic acid copolymer added metal), and other polyolefin modified resins, etc. Hot melt resins such as 2 or more kinds of composites. The powdery and granular melting point of the hot-melt polymer is usually equal to or lower than the melting point of the hot-melt fiber constituting the air-permeable substrate, and the non-hot-melt fiber is compared with a low-melting point. When the granular adsorbent is to be stuck on the air-permeable substrate's fuzzing surface, it is the sticky granular adsorbent on the air-permeable substrate or the fuzzed fibers, but the raised fibers should not stick to each other as an ideal form. The above melting point is set as Such conditions are sufficient. Of course, the air permeability will not be hindered, and the fluffed fibers may be bonded to each other. The amount of hot-melt resin used is preferably 1% to 200% based on the weight of the granular adsorbent used. Less than 1% will become insufficiently adhesive, making the granular adsorbent -14-200403096 unable to stick to air-permeable substrates such as fluffed nonwoven fabrics, and easily fall off from air-permeable substrates. On the one hand, more than 200% will become heat-induced. The molten resin covers most of the granular adsorbent surface and is formed to impair deodorization performance. At the same time, the molten valley resin is absorbed by the substrate during melting, which impairs the breathability of the substrate, and sometimes stains it? Appearance. The average particle diameter of the hot-melt resin is preferably smaller than the particle size of the particulate adsorbent, and preferably 10 to 100 μm. When the average particle size of the hot-melt resin is greater than 100 μxη, a sufficient adhesive force cannot be obtained, and when it is less than 10 μm, it becomes the cause of increasing the ventilation resistance. The above-mentioned air-permeable substrate or gas-purifying material is provided with other antibacterial, antifungal, anti-filter pathogenic, and non-flammable functions. Therefore, it can also be mixed or mixed with antibacterial, anti-mold, anti-filter pathogens in advance. Properties, flame retardancy, and functional agents are in the air-permeable substrate itself or in the hot-melt resin. In addition, these agents may be adhered to a granular adsorbent without impairing their original performance methods and amounts, or they may be coated on an air-permeable substrate for adhesion. Furthermore, functionalities other than the above, such as electret properties, can be imparted to the air-permeable substrate. The gas purification material of the present invention is ideally used for filtering and materials such as air purifiers and air conditioners. The gas purification material of the present invention is flat, or formed into a pleated shape or a wave shape as a filter material. For example, air can be purified by passing air through the surface of the gas purification material. Further, the gas purifying material of the present invention is processed with foam stripes, and formed into a honeycomb shape in a direction parallel to the gas purifying material to provide a large number of ventilation passages, and a gas purifying filter can also be obtained. In particular, since the two sides of the front and back surfaces of the base material are fluffed, and the granular adsorbent is bonded to the both sides of the front and back surfaces, an air purification filter with low pressure loss and higher contact gas removal efficiency per unit volume can be obtained. Although there are many well-known manufacturing methods of beehives, one of them is corrugated paper. The well-known corrugated paper is made of flat base paper with linear and segmented cores formed into a corrugated base paper, laminated with an adhesive layer, and manufactured using a device called a corrugating or corrugating machine. When the corrugated paper is cut in a plurality of layers or rolled into a roll, the intended honeycomb structure can be obtained. (For example, refer to the first to fourth figures of Japanese National Publication No. 57-1 1 9724.) In the present invention, a honeycomb structure can be produced in the same manner. In addition, the functional sheet of the gas purification material of the present invention may be, for example, a functional non-woven fabric, or it may be laminated on an air-permeable base material and added. The functional surface of the sheet may be a surface on which the particulate adsorbent is adhered on the napped surface, but the surface on which the particulate adsorbent is not adhered, although the surface is napped, may be a non-fluffed surface. However, since a non-fluffed air-permeable substrate can also perform the same function, it is desirable to provide a granular adsorbent on the adhered surface. As a method for placing the functional sheet on the air-permeable substrate, a functional sheet using a hot-melt polymer in the substrate sheet, and a method of bonding using a hot-melt resin powder or the like may be used. Any method may be used. Examples of the functional sheet include an electret melt-blown nonwoven fabric having a low pressure loss and a high collection efficiency, and a nonwoven fabric imparting an antibacterial agent or an antifungal agent. The electret melt-blown nonwoven fabric can be formed of nylon, polyethylene, polypropylene, etc., but is preferably a polyolefin fiber having a high electret effect. The following specifically describes the present invention, but the present invention is not limited to the embodiment.

According to the base material of the obtained gas purification material, a large amount of granular activated carbon was dropped. After removing all unbonded activated carbon, the amount of granular activated carbon remaining on the substrate was measured to be 110 g / m2. The obtained gas purification material was used in the same manner as in Example 2. The concentration was adjusted to 200403096 6 Oppm with a humidity of 50% toluene gas. The concentration was measured with a toluene gas detection tube manufactured by Gas Technology Co., Ltd., and when 50% was measured, As a result, the destruction process time was 21 minutes, and the life time was short. Comparative Example 3 Instead of fuzzing, 27g / m2 of a hot-melt nonwoven fabric made of a thermoplastic polyamide resin made by Nittobo Co., Ltd. was previously laminated on 34g of a polyester spunbond nonwoven fabric made by Mitsui Chemicals Co., Ltd. A gas purification material was obtained in the same manner as in Example 2 except for the upper part of the / m2 product. As in Comparative Example 2, a larger amount of granular activated carbon was dropped than the base material from which the gas purification material was obtained. After removing all unbonded activated carbon, the amount of granular activated carbon remaining on the base material was measured and found to be 130 g / m2. Using this gas purification material, the result of the destruction process time when 50% of the toluene gas was measured in the same manner as in Example 2 was 28 minutes, which was less than the life time of Example 2.

As a result of the bending test, no matter the amount of the granular activated carbon that was bonded, the granular activated carbon layer was not damaged, and good pleating was shown. characteristic. Using a 50 mm φ gas purification material, at room temperature, a 50% ammonia gas adjusted to a concentration of 60 ppm at a surface speed of 10 cm / sec, the concentration results were measured with an ammonia test tube made by Gas Technology Co., Ltd. The destruction process time at 50% is 48 minutes, a good life time is obtained, and the low result of the pressure loss is 1.3mmAq. Comparative Example 4 As in Example 3, without raising the air-permeable base material, a polyethylene-based hot-melt resin powder of 40 mesh passed product made by Tokyo Ink Co., Ltd. was previously mixed with 25% by weight of cola with granular activated carbon weight. 20% by weight of phosphoric acid-added carbon, manufactured by Li Chemical Co., Ltd., adjusted to a granular activated carbon with a mesh size of 20 mesh or more and a mesh size of less than 2 mesh. The weight of the granular activated carbon for spraying is 30 g / m2. Polyethylene-based hot-melt resin powder made by Tokyo Ink Co., Ltd. with a mesh size of 20 g / m2 is laminated with 34 g / m2 of polyester spunbond non-woven fabric made by Mitsui Chemicals Co., Ltd. from the upper part, and heated and pressed. After that, it was cooled to obtain a gas purification material. The weight per unit area of the obtained gas purification material was 43 Og / m2. As a result of measuring the amount of granular granular activated carbon, it was 300 g / m2. Although the amount of granular activated carbon dropped from the obtained gas purification material was small, the filter material Those who are rigid, and perform the bending test result, destroy the activated carbon layer, and cannot withstand the bending test. -20- 200403096 Using the obtained gas purification material, the ammonia gas with a humidity of 50% was adjusted to a concentration of 60 PPm, and the time of the destruction process at 50% was measured. The result was 21 minutes. Compared with Example 3, the life time was short and the pressure loss It also has a high result of 1.6mmAq. Example 4 A polyester spunbond nonwoven fabric of 34 g / m2 manufactured by Mitsui Chemicals Co., Ltd. was used in the same manner as in Example 2. The surface of the base material was raised in the same manner as in Example 1. On the raised surface, Tokyo Ink Co., Ltd. was used. A polyethylene-based hot-melt resin having an average particle diameter of 100 μm was prepared, and 10% by weight of a 20 mesh passing product of granular high-silica zeolite for aldehyde adsorption manufactured by Tosoh Co., Ltd. was mixed and dispersed as a granular zeolite amount of 300 g / m2 was heated and pressurized in the same manner as in Example 1, and then cooled to obtain a gas purification material. Regarding the obtained gas purification material, the non-fluffed surface was also fluffed in the same manner as in Example 2. The hot-melt resin mixed granular zeolite was sprayed again to 300 g / m2, followed by heating and pressing to obtain bound zeolite particles. The air-permeable substrate serves as a gas purification material on both sides of the fluff. The weight per unit area of the air-permeable substrate was 690 g / m2, and the amount of bonded zeolite particles was measured, and a large amount of bonding of 580 g / m2 was obtained.
