Description
本発明は、各種ウイルスを不活性にする抗ウイルス性壁紙に関する。 The present invention relates to an antiviral wallpaper that inactivates various viruses.
厚生労働省の鳥インフルエンザ(Ｈ５Ｎ１)発生国及び人での確定症例によると、２００３年１１月以降、アジア、欧州、中東、アフリカ等の広い地域に於いて高病原性鳥インフルエンザが発生している。鳥インフルエンザの感染は家禽類間だけでなく、家禽類から霊長類への感染も確認されており、殊にヒトに関してはこれまでに６００余名が感染し、内３５０名以上が死亡している。さらに鳥インフルエンザウイルスは人インフルエンザウイルスとの交雑によって、或いはそれ単独でも変異し、強毒化し得る危険性をはらんでいる。
そのため、ウイルスを迅速に不活化できる技術や製品が渇望されている。中でもウイルスと接触することが予測される医療施設などに使用される建築用内装材においては、ウイルスの不活化が特に望まれており、殊に施工面積の大半を占める壁紙に対する抗ウイルス性の切望は大きい。
According to the confirmed cases in avian influenza (H5N1) countries and people of the Ministry of Health, Labor and Welfare, highly pathogenic avian influenza has occurred in a wide area such as Asia, Europe, Middle East and Africa since November 2003. Infection of avian influenza has been confirmed not only among poultry, but also from poultry to primates. Especially about humans, more than 600 people have been infected, and more than 350 people have died. . Furthermore, the avian influenza virus poses a risk that it can be mutated and toxicated by crossing with human influenza virus or by itself.
Therefore, there is a craving for technologies and products that can quickly inactivate viruses. In particular, in the interior materials for buildings used in medical facilities that are expected to come into contact with viruses, it is particularly desirable to inactivate viruses. Is big.
壁紙には、塩化ビニル樹脂等の塩化ビニル系樹脂やオレフィン系樹脂が多く用いられている。特に塩化ビニル系樹脂は安価で諸物性に優れ、表面に微細な凹凸を形成するエンボス加工を施すことでさらに意匠性を付与できることから専ら採用されている。 For wallpaper, vinyl chloride resins such as vinyl chloride resin and olefin resins are often used. In particular, a vinyl chloride resin has been adopted exclusively because it is inexpensive and excellent in various physical properties, and can be further imparted with design by embossing to form fine irregularities on the surface.
扨て、下記特許文献１では繊維に抗ウイルス性を付与するものとして、金属イオンを担持したビニル―マレイン酸共重合高分子を用いる方法が提案されている。しかし乍らこの発明をポリ塩化ビニル系樹脂から成る壁紙に適用する技術については示されていない。 On the other hand, in Patent Document 1 below, a method using a vinyl-maleic acid copolymer polymer carrying metal ions has been proposed as a method for imparting antiviral properties to fibers. However, it does not show a technique for applying the present invention to wallpaper made of polyvinyl chloride resin.
本発明の発明者は、スルホン酸系界面活性剤を含有したポリ塩化ビニル系壁紙が、接触したウイルスのウイルス力価を迅速に低減してウイルスを不活化できることを見出した。しかしスルホン酸系界面活性剤を壁紙製造時に添加すると、ポリ塩化ビニル樹脂との分散性が乏しく、壁紙表面に皺等の外観不良を引き起こすとの未知の課題を見出した。 The inventor of the present invention has found that a polyvinyl chloride wallpaper containing a sulfonic acid surfactant can rapidly reduce the virus titer of the virus in contact with the virus and inactivate the virus. However, the present inventors have found an unknown problem that when a sulfonic acid-based surfactant is added at the time of wallpaper production, the dispersibility with the polyvinyl chloride resin is poor, causing appearance defects such as wrinkles on the wallpaper surface.
即ち本発明は、接触したウイルスのウイルス力価を迅速に低減してウイルスを不活化させる外観の優れた抗ウイルス性壁紙を提供することを目的とする。 That is, an object of the present invention is to provide an antiviral wallpaper having an excellent appearance that rapidly inactivates a virus by rapidly reducing the virus titer of the contacted virus.
前記課題に対し、スルホン酸系界面活性剤の添加方法について鋭意検証した結果、スルホン酸系界面活性剤を予め添加したペースト加工用塩化ビニル樹脂を使用して壁紙を製造することで、美観を損ねることなく好適に抗ウイルス性壁紙を得られることを見出した。 As a result of diligent verification of the method for adding the sulfonic acid-based surfactant to the above-mentioned problems, the wallpaper is made using the vinyl chloride resin for paste processing to which the sulfonic acid-based surfactant has been added in advance. It has been found that an antiviral wallpaper can be suitably obtained without any problem.
本発明の抗ウイルス性壁紙は、ウイルスと接触後に短時間でウイルス力価を低減化してウイルスを不活化させ、外観にも優れる。 The antiviral wallpaper of the present invention is excellent in appearance by reducing the virus titer in a short time after contact with the virus to inactivate the virus.
本発明の抗ウイルス性壁紙は、予めスルホン酸系界面活性剤を１．２重量部以上含むペースト加工用塩化ビニル樹脂を樹脂成分として含む樹脂層と基材層とを備えることが肝要である。壁紙の製造工程において、ペースト加工用塩化ビニルと、可塑剤や充填剤、安定剤及び発泡剤等を混合してゾルを作製する過程があるが、スルホン酸系界面活性剤は可塑剤に不溶であるため、この過程で混合するとゾル中の分散性が悪く、製品にスジなどの外観不良を引き起こし美観を損ねる。
他方、スルホン酸系界面活性剤は水溶性である。また、乳化重合またはシード乳化重合でペースト加工用塩化ビニル樹脂を製造する際に、重合後の中間体的形態として水を溶媒とするラテックスが得られる。したがって、このラテックスにスルホン酸系界面活性剤を添加することで、スルホン酸系界面活性剤が塩化ビニル樹脂中へ良好に分散される。このように、スルホン酸系界面活性剤を重合後のラテックスに添加することで、重合条件に影響を与えることなく所望の性状を有するペーストポリ塩化ビニル樹脂が得られる。斯かる手法で得られた予めスルホン酸系界面活性剤を含有したペースト加工用塩化ビニル樹脂を用いることで、美観を損ねることなく壁紙を得ることができる。
It is important that the antiviral wallpaper of the present invention comprises a resin layer and a base material layer containing a vinyl chloride resin for paste processing containing 1.2 parts by weight or more of a sulfonic acid surfactant in advance as a resin component. In the wallpaper manufacturing process, there is a process of making sols by mixing vinyl chloride for paste processing with plasticizers, fillers, stabilizers, foaming agents, etc., but sulfonic acid surfactants are insoluble in plasticizers. For this reason, when mixed in this process, the dispersibility in the sol is poor, causing appearance defects such as streaks in the product and deteriorating the appearance.
On the other hand, the sulfonic acid surfactant is water-soluble. Moreover, when producing a vinyl chloride resin for paste processing by emulsion polymerization or seed emulsion polymerization, a latex using water as a solvent is obtained as an intermediate form after polymerization. Therefore, by adding a sulfonic acid surfactant to this latex, the sulfonic acid surfactant is well dispersed in the vinyl chloride resin. Thus, by adding the sulfonic acid surfactant to the latex after polymerization, a paste polyvinyl chloride resin having desired properties can be obtained without affecting the polymerization conditions. By using the vinyl chloride resin for paste processing previously containing a sulfonic acid surfactant obtained by such a technique, a wallpaper can be obtained without impairing the beauty.
本発明に用いるペースト加工用塩化ビニル樹脂の原体となる塩化ビニル樹脂としては、特に制限されないが、例えば重合度が６００〜３０００のものを好適に用いることができる。 Although it does not restrict | limit especially as a vinyl chloride resin used as the raw material of the vinyl chloride resin for paste processing used for this invention, For example, a polymerization degree 600-3000 can be used suitably.
本発明に用いるスルホン酸系界面活性剤としては、例えばアルキルベンゼンスルホン酸系化合物、アルキルジフェニルエーテルジスルホン酸系化合物、アルキルナフタレンスルホン酸系化合物、アルキル硫酸エステル系化合物、ポリオキシエチレンアルキル硫酸エステル系、ナフタレンスルホン酸ホルマリン縮合物系化合物等が挙げられる。この中でも抗ウイルス性に優れるとの観点からアルキルベンゼンスルホン酸系化合物、アルキルジフェニルエーテルジスルホン酸系化合物、アルキルナフタレンスルホン酸系化合物が好ましく、特に抗ウイルス性に優れるアルキルベンゼンスルホン酸系化合物がより好ましい。
本発明で用いるスルホン酸系界面活性剤において、スルホン酸基は例えばインフルエンザウイルスのノイライミダーゼとの親和性が高く、阻害作用を現すことができる。また官能基の構造はノイライミダーゼへの接近に関して影響を示し、嵩高くなく立体障害を受け難い構造が肝要となる。その点において、アルキルベンゼンスルホン酸系界面活性剤は好適であり、特にドデシルベンゼンスルホン酸が好ましい。
さらに、上記のスルホン酸系界面活性剤としては、スルホン酸塩系界面活性剤が好ましく、具体的にはナトリウム塩、カリウム塩などのアルカリ金属塩、カルシウム、バリウム等のアルカリ土類金属塩を好適に用いることができる。特にドデシルベンゼンスルホン酸ナトリウム（ＤＢＳ）が好ましい。
また、複数のスルホン酸系界面活性剤を抗ウイルス性が阻害されない限りにおいて添加してもよく、その他の種類の界面活性剤を加えることも制限されない。
Examples of the sulfonic acid surfactant used in the present invention include alkylbenzene sulfonic acid compounds, alkyl diphenyl ether disulfonic acid compounds, alkyl naphthalene sulfonic acid compounds, alkyl sulfate esters, polyoxyethylene alkyl sulfate esters, naphthalene sulfones. Examples include acid formalin condensate compounds. Of these, alkylbenzenesulfonic acid compounds, alkyldiphenyl ether disulfonic acid compounds, and alkylnaphthalenesulfonic acid compounds are preferable from the viewpoint of excellent antiviral properties, and alkylbenzenesulfonic acid compounds that are particularly excellent in antiviral properties are more preferable.
In the sulfonic acid surfactant used in the present invention, the sulfonic acid group has a high affinity with, for example, influenza virus neuramidase, and can exhibit an inhibitory action. In addition, the structure of the functional group has an influence on the approach to the neuraimidase, and a structure that is not bulky and hardly receives steric hindrance is important. In that respect, alkylbenzene sulfonic acid surfactants are preferred, and dodecylbenzene sulfonic acid is particularly preferred.
Furthermore, as the sulfonic acid surfactant, a sulfonate surfactant is preferable. Specifically, alkali metal salts such as sodium salt and potassium salt, and alkaline earth metal salts such as calcium and barium are preferable. Can be used. In particular, sodium dodecylbenzenesulfonate (DBS) is preferred.
Further, a plurality of sulfonic acid surfactants may be added as long as antiviral properties are not inhibited, and addition of other types of surfactants is not limited.
本発明に用いる樹脂成分には、スルホン酸系界面活性剤を１．２重量％以上含むことが必要であり、好適には１．５重量％以上４９．９重量％以下、更に好ましくは２重量％以上２０重量％以下である。１．２重量％を下回ると抗ウイルス性が安定して発現しない。ここでスルホン酸系界面活性剤を１．５重量％以上含むことでより安定した抗ウイルス性が発現され、さらに２重量％以上とすることでより高い抗ウイルス性が得られる。また２０重量％以下とすることで加工性がより安定する点で優れる。 The resin component used in the present invention needs to contain 1.2% by weight or more of a sulfonic acid surfactant, preferably 1.5% by weight or more and 49.9% by weight or less, more preferably 2% by weight. % To 20% by weight. If it is less than 1.2% by weight, the antiviral property is not stably expressed. Here, a more stable antiviral property is expressed by containing 1.5% by weight or more of the sulfonic acid surfactant, and a higher antiviral property is obtained by setting the content to 2% by weight or more. Moreover, it is excellent in the point that workability is more stabilized by setting it as 20 weight% or less.
本発明に用いるペースト加工用塩化ビニル樹脂として、上記予めスルホン酸系界面活性剤を１．２重量％以上含むペースト加工用塩化ビニル樹脂を単独で用いても良いし、他の塩化ビニル樹脂と混合して樹脂成分として用いてもよい。但し何れの場合に於いても、樹脂成分すなわち塩化ビニル樹脂総量に対し、スルホン酸系界面活性剤を１．２重量％以上含むことが必要であり、好適には１．５重量％以上４９．９重量％以下、更に好ましくは２重量％以上２０重量％以下である。１．２重量％を下回ると抗ウイルス性が安定して発現しない。 As the vinyl chloride resin for paste processing used in the present invention, the vinyl chloride resin for paste processing containing 1.2% by weight or more of the sulfonic acid surfactant in advance may be used alone, or mixed with other vinyl chloride resins. And may be used as a resin component. However, in any case, it is necessary to contain 1.2% by weight or more of the sulfonic acid surfactant with respect to the total amount of the resin component, that is, the vinyl chloride resin, preferably 1.5% by weight or more. It is 9% by weight or less, more preferably 2% by weight or more and 20% by weight or less. If it is less than 1.2% by weight, the antiviral property is not stably expressed.
必要に応じ、本発明の抗ウイルス性壁紙に発泡剤を用いてもよいが、その場合の添加量は樹脂成分１００重量部に対し０．０１重量部以上５重量部以下、好ましくは０．１重量部以上４重量部以下、さらには０．５重量部以上３重量部以下に制限することが望ましい。
発泡剤の添加量を樹脂成分１００重量部に対し０．１重量部以上とすることで発泡倍率がより高い壁紙を得ることができ、０．５重量部以上とすることで発泡倍率をさらに高めることが可能となる。
一方で、本発明の抗ウイルス性壁紙においてスルホン酸系界面活性剤は塩化ビニル樹脂セグメント間の界面に存在し、含有量が増加するとその占有領域が増大することが確認されている。これは塩化ビニル樹脂セグメント同士の密着性を低下させ、弾性率低下を引き起こす。弾性率が低下すると発泡剤の分解よって生じる発泡セルの保持が困難になりその収縮を引き起こし得る。
発泡剤の添加量が樹脂成分１００重量部に対し５重量部以下であれば、発泡セルの収縮の影響はほぼないか、軽微であり壁紙の美観は損なわれない。しかし、５重量部を超えると発泡セルの収縮が大きくなり、変色等の外観不良を引き起こす場合がある。
If necessary, a foaming agent may be used for the antiviral wallpaper of the present invention. In this case, the addition amount is 0.01 to 5 parts by weight, preferably 0.1 to 100 parts by weight of the resin component. It is desirable to limit the amount to not less than 4 parts by weight and more preferably not less than 0.5 parts by weight and not more than 3 parts by weight.
By setting the addition amount of the foaming agent to 0.1 parts by weight or more with respect to 100 parts by weight of the resin component, a wallpaper having a higher foaming ratio can be obtained, and by setting it to 0.5 parts by weight or more, the foaming ratio is further increased. It becomes possible.
On the other hand, in the antiviral wallpaper of the present invention, the sulfonic acid surfactant is present at the interface between the vinyl chloride resin segments, and it is confirmed that the occupied area increases as the content increases. This reduces the adhesion between the vinyl chloride resin segments and causes a decrease in the elastic modulus. When the elastic modulus is lowered, it becomes difficult to hold the foamed cells caused by the decomposition of the foaming agent, and the shrinkage may be caused.
If the addition amount of the foaming agent is 5 parts by weight or less with respect to 100 parts by weight of the resin component, the effect of shrinkage of the foamed cell is almost or slight and the appearance of the wallpaper is not impaired. However, when the amount exceeds 5 parts by weight, the shrinkage of the foamed cells increases, which may cause appearance defects such as discoloration.
本発明の抗ウイルス性壁紙に平滑性や強度等を要求する目的で、実質的に発泡剤を含まなくすることも、本発明の好適な実施形態の一つである。 One of the preferred embodiments of the present invention is to make the antiviral wallpaper of the present invention substantially free from a foaming agent for the purpose of requiring smoothness and strength.
本発明に用いる発泡剤としては公知のものを用いることができ、例えばアゾジカルボンアミド（ＡＤＣＡ）、アゾビスホルムアミド、オキシベンゼンスルホニルヒドラジド、パラトルエンスルホニルヒドラジド等が挙げられる。 As the blowing agent used in the present invention, known ones can be used, and examples thereof include azodicarbonamide (ADCA), azobisformamide, oxybenzenesulfonyl hydrazide, paratoluenesulfonyl hydrazide and the like.
本発明の抗ウイルス性壁紙には、抗ウイルス性を阻害させない限りに於いて表面にトップコート層を設けても良い。トップコート層は、例えばトップコート用樹脂組成物を塗料にして塗工することで設けることができ、トップコート用樹脂としては、アクリル系樹脂、ウレタン系樹脂、フッ素系樹脂などを用いることができる。さらにトップコート処理によって壁紙表面の動摩擦係数を低減できれば、表面強化壁紙性能規定に準拠した試験に於いて４級以上を有すことが可能となる。この場合、動摩擦係数は例えばＡＳＴＭ Ｄ １８９４に準拠した試験で０．５以下とすることが好ましい。 The antiviral wallpaper of the present invention may be provided with a top coat layer on the surface as long as the antiviral property is not inhibited. The topcoat layer can be provided, for example, by applying a resin composition for topcoat as a paint, and acrylic resin, urethane resin, fluorine resin, or the like can be used as the topcoat resin. . Furthermore, if the dynamic friction coefficient of the wallpaper surface can be reduced by the top coat treatment, it becomes possible to have a grade 4 or higher in a test based on the surface-enhanced wallpaper performance regulations. In this case, the coefficient of dynamic friction is preferably set to 0.5 or less, for example, in a test based on ASTM D 1894.
ここでトップコート層がコート剤の塗工により設けられる場合、コート剤は樹脂層に細かな隙間を有する状態で塗布される。したがって、樹脂層に含まれるスルホン酸系界面活性剤は表面に一部露出することができるために、ウイルスが壁紙表面に接触した場合に該ウイルスを攻撃することが可能となる。斯くしてトップコート層を設けても抗ウイルス性が発揮される。 Here, when the topcoat layer is provided by coating the coating agent, the coating agent is applied in a state having a fine gap in the resin layer. Therefore, since the sulfonic acid surfactant contained in the resin layer can be partially exposed on the surface, it is possible to attack the virus when the virus contacts the wallpaper surface. Thus, even if a top coat layer is provided, antiviral properties are exhibited.

エンベロープを有するウイルスとしては、例えば鳥インフルエンザウイルス、人インフルエンザウイルス、豚インフルエンザウイルス等のイフルエンザウイルス、Ｂ型肝炎ウイルス、Ｃ型肝炎ウイルス、ヒト免疫不全ウイルス、水痘帯状疱疹ウイルス、単純ヘルペスウイルス、ヒトヘルペスウイルス、ムンプスウイルス、ＲＳウイルス等が挙げられる。

[Evaluation of antiviral properties]
Antivirus was evaluated as follows.
Avian influenza [A / whisling swan / Shimane / 499/83 (H5N3)] was used as a test virus.
The virus grown in the chorioallantoic cavity of the developing chicken egg was diluted to 1.0 × 10 6 EID 50 /0.1 mL with sterile phosphate buffered saline (PBS) to prepare a virus solution did. 0.22 mL of the virus solution was placed on the test body (5 cm × 5 cm), and it was covered with a polyethylene film (4 cm × 4 cm). The test specimen was placed in a petri dish and allowed to stand for 1 hour in an incubator set at 20 ° C. to bring the specimen into contact with the virus. The virus solution (sample) on the test specimen was collected, diluted 10-fold in steps with PBS, and 0.1 mL was inoculated into the chorioallantoic cavity of 10-day-old chicken eggs. After inoculating and growing chicken eggs at 37 ° C. for 2 days, the presence or absence of virus growth in the chorioallantoic cavity was confirmed by the hemagglutination test, and the virus titer in the sample was calculated by the method of Reed and Muench.
The difference between the “virus titer (after 1 hour)” and the “virus titer (before the test)” represents the strength of the antiviral property, and the larger the difference, the stronger the antiviral property.

［評価結果］
実施例１乃至６は、外観の美観を保持しつつ、ウイルス力価が「ウイルス接触前」と「ウイルス接触１時間後」で少なくとも４．０以上（約１０−４.０＝１００００分の１) 減少させており、高い抗ウイルス性を有している。
さらに、実施例５、６によるとトップコート層を付与することで表面強化性が４級以上になることも示されている。
[Evaluation results]
In Examples 1 to 6, while maintaining the aesthetic appearance, the virus titer was at least 4.0 or more (about 10 −4.0 = 1 / 10,000) at “before virus contact” and “after virus contact 1 hour”. ) Reduced and highly antiviral.
Furthermore, according to Examples 5 and 6, it is also shown that the surface reinforcing property becomes 4th or higher by providing the topcoat layer.
これに対し、比較例１では塩化ビニル樹脂に対するスルホン酸系界面活性剤の含有量が１．０重量％と小さいため、ウイルス力価が「ウイルス接触前」と「ウイルス接触１時間後」で２．５（１０−２．５＝約３１００分の１）しか減少しておらず、実施例と比較して抗ウイルス性が低いとの試験結果になっている。
さらにスルホン酸系界面活性剤としてＤＢＳの紛体原体をペースト作成時に添加した比較例２では、抗ウイルス性は向上したものの壁紙外観が不良となった。
On the other hand, in Comparative Example 1, since the content of the sulfonic acid surfactant relative to the vinyl chloride resin is as small as 1.0% by weight, the virus titer is 2 before “virus contact” and “after virus contact 1 hour”. .5 (10 −2.5 = about 1/100 ), which is a test result indicating that the antiviral property is low as compared with the Examples.
Furthermore, in Comparative Example 2 in which a powdery raw material of DBS was added as a sulfonic acid surfactant at the time of preparing the paste, although the antiviral property was improved, the wallpaper appearance was poor.
