Description

作為通孔防火材之複合層合物、其製法及使用方法 Composite laminate as through-hole fireproof material, preparation method and use method thereof

本發明大體上關於一種作為通孔防火材之複合壓合物，其是用於防止多層建築物著火時可能產生之火、煙及燻煙擴散之隔火系統的一部分。本發明也關於製造或利用該複合層合物作為通孔防火材之方法。 SUMMARY OF THE INVENTION The present invention generally relates to a composite compact as a through-hole fireproofing material which is part of a fire barrier system for preventing the spread of fire, smoke and fumes that may be generated when a multi-story building is on fire. The invention also relates to a method of making or using the composite laminate as a through-hole fireproof material.

在有限空間內，如在多層建築物內火、煙及燻煙係會危害生命的。若火係源自該建築結構之地板與天花板間之空間，該火及所造成的煙和燻煙經常容易擴散至該建築物中其他開放空間，特別是擴散至該火源點上方之開放空間。 In a limited space, such as fire, smoke and smoke in a multi-storey building can be life-threatening. If the fire originates from the space between the floor and the ceiling of the building structure, the fire and the smoke and smoke caused by the fire often spread easily to other open spaces in the building, especially to the open space above the fire source point. .

此火、煙及燻煙擴散至較高區域背後有多種原因。導線管、管線及類似物與其所穿過之地板/天花板之間的區域已知為"通孔"。若無防火，通孔提供低耐火、煙及燻煙之區域，而且本質上被用作"煙囪"。 There are many reasons behind the spread of this fire, smoke and smoke to higher areas. The area between the conduit, the pipeline and the like and the floor/ceiling it passes through is known as a "through hole". If there is no fire protection, the through holes provide areas of low fire, smoke and smoke, and are essentially used as "chimneys".

這些區域可以市售阻燃及發泡防火泥、填縫劑、包覆物或襯墊，技術上已知的"防火材"裝填之。代表性的防火材產品係揭示於明尼蘇達採礦及製造公司(3M)之產品型錄編號98-0701-3508-6(1990發行)中。該等3M產品是目前已知商標名稱為"CP 25WB+"及"Firedam"(凝固型防火泥)；"MPP-4S"及"MPS-2"(非凝固型防火泥)；"FS-195+"(防火帶)及"CS-195+"(防火板)；及"Interam"和"Interam E-5"(襯墊)之產品。這些產品係個別描述於受讓人之美國專利第3,916,057號；第4,273,879號；第4,305,992號；第4,364,210號；第 4,433,732號；及第4,467,577號中。 These areas are commercially available as flame retardant and foam fireproof muds, caulks, wraps or liners, as well as "fireproof materials" known in the art. A representative fireproofing product product is disclosed in Minnesota Mining and Manufacturing Company (3M) Product Catalog No. 98-0701-3508-6 (issued 1990). These 3M products are currently known under the trade names "CP 25WB+" and "Firedam" (solidified fire mud); "MPP-4S" and "MPS-2" (non-solidified fire mud); "FS-195+ "(Fireproof belt) and "CS-195+" (fireproof board); and "Interam" and "Interam E-5" (liner) products. These products are described in each of the assignee's U.S. Patent Nos. 3,916,057; 4,273,879; 4,305,992; 4,364,210; No. 4,433,732; and No. 4,467,577.

在這些市售防火材產品中，3M CS-195+產品已知是一具有特定構造之三明治型通孔防火材且可用於密封穿過防火牆及地板之貫穿物(如電纜、電纜槽、導線管、配線管及管子)及其支撐構件周圍開口並可用於電纜槽、電纜管線及大空白處以防火擴散，其中該特定構造主要係由鋼質層、阻燃材料及鋼網組成的。雖然此產品具有令人滿意的隔火性質，但由於該所用阻燃材料的製造成本昂貴、笨重不易安裝、不易彎曲而且欲切割以符合貫穿物外形時容易分離。 Among these commercially available fireproofing products, 3M CS-195+ is known as a sandwich-type through-hole fireproofing material with a specific construction and can be used to seal through the firewall and floor penetrations (such as cables, cable ducts, conduits). , wiring tubes and tubes) and their support members around the opening and can be used for cable troughs, cable lines and large blanks for fireproof diffusion, wherein the specific structure is mainly composed of steel layer, flame retardant material and steel mesh. Although this product has a satisfactory fire barrier property, it is expensive to manufacture, cumbersome to install, difficult to bend, and easy to separate when it is cut to conform to the shape of the penetrating material.

因此仍需要一種較輕、較容易製造且製造成本較便宜並且同時可符合ASTM E 814防火試驗標準方法中所陳述對穿孔防火材之要求的三明治型穿孔防火材。本發明係朝向符合此項需求前進。 There is therefore still a need for a sandwich perforated fire barrier that is lighter, easier to manufacture, and less expensive to manufacture and that meets the requirements for perforated firewood as stated in the ASTM E 814 Fire Test Standards method. The present invention is directed toward meeting this need.

因此本發明目的係提供一種作為穿孔防火材之複合層合物，其比先前技術之產品更輕、更容易製造且製造成本更便宜，而且具有相等或更優良之耐火表現。 It is therefore an object of the present invention to provide a composite laminate as a perforated fireproofing material which is lighter, easier to manufacture and less expensive to manufacture than prior art products, and which has equal or superior fire resistance.

特別地，本發明提供一種作為穿孔防火材之複合層合物，其包含：(a)一耐高溫金屬層；(b)至少一可撓曲防火毯材料之中間層；及(c)一絲網層，其中安裝時，該金屬層係面朝外，該金屬層與絲網層係黏在該中間層上，而且基於ASTM試驗E 814之等級標準，該複合層合物有能力在從900℃至1100℃之溫度下通過1至3小時之耐火等級且後續在30 psi水壓下通過1至3小時之軟管水柱等級而無分解。 In particular, the present invention provides a composite laminate as a perforated fireproofing material comprising: (a) a high temperature resistant metal layer; (b) at least one intermediate layer of a flexible fire resistant carpet material; and (c) a wire mesh a layer in which the metal layer is facing outward, the metal layer and the screen layer are adhered to the intermediate layer, and based on the ASTM test E 814 grade standard, The composite laminate has the ability to pass through a fire rating of from 1 to 3 hours at a temperature of from 900 ° C to 1100 ° C and subsequent passage through a hose column of 1 to 3 hours at 30 psi water pressure without decomposition.

本發明另一個目的係提供一種製造本發明作為穿孔防火材之複合層合物的方法。 Another object of the present invention is to provide a method of making the composite laminate of the present invention as a perforated fireproof material.

本發明另一個目的係關於一種本發明作為穿孔防火材之複合層合物結合其他隔火材料用於密封穿過防火牆及地板之貫穿物及用於電纜槽、電纜管線及大空白處之用途。 Another object of the present invention is to provide a composite laminate of the present invention as a perforated fireproofing material in combination with other fire barrier materials for sealing through the penetration of the firewall and the floor and for use in cable troughs, cable runs and large spaces.

關於圖1，本發明作為穿孔防火材之複合層合物10包含一層可撓曲防火毯材料11。耐高溫金屬層12係層壓在該防火毯材料層11一表面上，且絲網層13係黏接在該防火毯材料層11另一表面上。 With respect to Figure 1, the composite laminate 10 of the present invention as a perforated fireproofing material comprises a layer of flexible fire resistant carpet material 11. The high temperature resistant metal layer 12 is laminated on a surface of the fire blanket material layer 11, and the screen layer 13 is adhered to the other surface of the fire blanket material layer 11.

該可撓曲防火毯材料可為呈現良好隔熱性質並可在高溫下保持安定之市售防火毯。習慣上，利用防火毯覆蓋在火上，使該火缺少氧氣或包裹在衣服著火者周圍以抑制危險。防火毯之另一項特定用途是密封建築物接縫，如受讓者之U.S.5,765,332中所描述之防火毯材料的用途。 The flexible fire resistant carpet material can be a commercially available fireproof blanket that exhibits good thermal insulation properties and can be kept stable at high temperatures. It is customary to cover the fire with a fire blanket so that the fire is deficient in oxygen or wrapped around the person wearing the fire to suppress the danger. Another specific use of the fire blanket is to seal the seams of the building, such as the use of the fire blanket material described in U.S. Patent 5,765,332.

在本發明申請案中，防火毯的厚度及密度自然將隨所選材料及所需隔熱程度和耐熱性而變。 In the present application, the thickness and density of the fire blanket will naturally vary with the material selected and the degree of thermal insulation and heat resistance desired.

Organic and inorganic binders can be present in the fiber mat. Useful glass fibers, including chopped glass fibers (e.g., magnesium aluminosilicate glass fibers), are commercially available, for example, from the Owens-Corning Fiberglass Company of Granville, Ohio, under the trade designation "S2-GLASS." Suitable fiberglass mats (e.g., vermiculite mats) are, for example, those sold under the trade designation "FIBERGLASS" by Owens-Corning Fiberglass. Other ceramic fiber materials suitable for use as the layer of the flexible fire resistant carpet material of the present invention include ceramic oxide fibers (e.g., a small diameter melt available under the trade designation "FIBERFRAX DURABACK Blanket" by Carborundum, Inc. of Niagara Falls, New York.

NEXTEL" ceramic oxide fiber (such as the commercially available aluminum silicate ceramic oxide fiber under the trade name "NEXTEL 440", commercially available aluminum borosilicate ceramic oxide fiber under the trade name "NEXTEL 312" and the trade name Commercially available alumina ceramic oxide fiber of "NEXTEL 610").

有用的礦棉襯墊(如衍生自主要組份為矽石、氧化鈣、氧化鋁及氧化鎂之鼓風爐渣的礦棉襯墊)包括這些，例如可由伊利諾州芝加哥之U.S.Gypsum公司所購得商標名稱為"THERMOFIBER"之產品。 Useful mineral wool liners (such as mineral wool liners derived from blast furnace slags whose major components are vermiculite, calcium oxide, alumina, and magnesia) include these, for example, available from USGypsum Corporation of Chicago, Ill. The product name is "THERMOFIBER".

該可撓曲防火毯材料可由發泡防火毯材料或由吸熱防火毯材料構成。吸熱材料吸熱並可用於保護構造組件以防高溫作用。有用的吸熱防火毯材料係，例如由3M公司購得商標名稱為"INTERAM MAT E-5"之產品。 The flexible fireproof blanket material may be composed of a foamed fireproof carpet material or an endothermic fireproof carpet material. The heat absorbing material absorbs heat and can be used to protect the structural components from high temperatures. Useful endothermic fire blanket materials are, for example, those sold under the trade designation "INTERAM MAT E-5" by 3M Company.

較佳地，該可撓曲防火毯材料是一暴露在高於約200℃之溫度時，可膨脹成低密度絕熱毯之發泡防火毯材料。可用於實施本發明之發泡防火毯材料包括聚合物黏合劑、填料及發泡粒子。可用的發泡粒子包括矽酸鹽、膨脹石墨及蛭石。一般，這些粒子係與足量添加劑混合以製造一具有合適膨脹及撓曲性特徵之薄板。當該發泡板材料受到熱或火焰時，其膨脹並作為熱、煙及燻煙之屏障。適合的發泡防火毯材料係更完整地描述於美國專利第4,305,992號中，將該案以引用方式併入本文中。 Preferably, the flexible fireproof blanket material is exposed to a temperature above about 200 ° C. At the temperature, it can be expanded into a foamed fireproof blanket material of a low density insulation blanket. Foamed fireproof carpet materials useful in the practice of the present invention include polymeric binders, fillers, and expanded particles. Useful expanded particles include phthalates, expanded graphite, and vermiculite. Typically, these particles are mixed with a sufficient amount of additives to produce a sheet having suitable expansion and flexibility characteristics. When the foamed sheet material is subjected to heat or flame, it expands and acts as a barrier to heat, smoke and smoke. A suitable foamed fireproofing carpet material is more fully described in U.S. Patent No. 4,305,992, the disclosure of which is incorporated herein by reference.

可用的發泡防火毯材料是，例如由3M公司所購得商標名稱為"INTERAM I-10A"之產品。此3M公司產品是一0.5厘米厚具有0.076釐米(3密耳)厚層壓鋁箔的發泡襯墊。當用於本發明時，除去3M公司產品之鋁箔層並將該剩餘發泡襯墊部分用作作為穿孔防火材之該複合層合物的可撓曲防火毯材料層。 Useful foaming fireproofing carpet materials are, for example, those sold under the trade name "INTERAM I-10A" by 3M Company. The 3M product is a 0.5 cm thick foamed liner with a 0.076 cm (3 mil) thick laminated aluminum foil. When used in the present invention, the aluminum foil layer of the 3M Company product is removed and the remaining foamed liner portion is used as the flexible fire resistant carpet material layer of the composite laminate as a perforated fireproof material.

根據本發明，黏在該防火毯材料層一表面之金屬表面係用於提供具有支撐強度可作為穿孔防火材之複合層合物，而且黏在該防火毯材料層另一表面之絲網層係另外用於保持該防火毯材料層的形狀而不分解。而且，由於該金屬層及金屬網層之物理性質，本發明作為穿孔防火材之複合層合物可彎成實際用途所需形狀，如C-通道接合部件、直角-通道接合部件或U-形彎曲部件。 According to the present invention, the metal surface adhered to a surface of the fire blanket material layer is used to provide a composite laminate having a support strength as a perforated fireproof material, and a screen layer adhered to the other surface of the fire blanket material layer. Also used to maintain the shape of the fire blanket material layer without decomposition. Moreover, due to the physical properties of the metal layer and the metal mesh layer, the composite laminate of the present invention as a perforated fireproof material can be bent into a shape required for practical use, such as a C-channel joint member, a right-angle joint member or a U-shape. Curved parts.

該金屬層及該絲網層皆可為任何熟諳此技者已知且慣用的耐高溫金屬，如(但不限於)各等級之鍍鋅鋼、鋁合金、不銹鋼及銅。其厚度係視所選金屬物種、成本、支撐強度及安置處之切割方便性間的平衡而定。在一本發明具體實施例中，該耐高溫金屬層是一厚度為0.125至0.625釐米之鍍鋅鋼層，例如厚度為0.399釐米之30號(gauge)鍍鋅鋼板，而且該絲網層是一厚度為從0.125至0.625釐米之鋼絲網，例如厚度為30號之鍍鋅鋼線。 Both the metal layer and the screen layer can be any refractory metal known to those skilled in the art, such as, but not limited to, various grades of galvanized steel, aluminum alloy, stainless steel, and copper. The thickness depends on the selected metal species, cost, support strength and It depends on the balance between the convenience of cutting. In a specific embodiment of the invention, the refractory metal layer is a galvanized steel layer having a thickness of 0.125 to 0.625 cm, such as a gauge galvanized steel sheet having a thickness of 0.399 cm, and the screen layer is a A wire mesh having a thickness of from 0.125 to 0.625 cm, such as a galvanized steel wire having a thickness of 30.

雖然已發現厚度為0.125至0.625釐米之鍍鋅鋼板及厚度為0.125至0.625釐米之鋼絲可提供可信賴性質，但應了解適合用於本發明之耐高溫金屬層及絲網層可根據實際用途而變且不應只限定在上述特定具體實施例。 Although it has been found that a galvanized steel sheet having a thickness of 0.125 to 0.625 cm and a steel wire having a thickness of 0.125 to 0.625 cm provide a reliable property, it is understood that the refractory metal layer and the screen layer suitable for use in the present invention may be used depending on the practical use. The changes should not be limited to the specific embodiments described above.

In addition, based on technical and commercial considerations, the composite laminate of the present invention as a perforated fireproofing material may additionally comprise an aluminum foil layer having a thickness of 0.05 to 0.125 cm adhered to the wire mesh layer.

因此，另一個本發明作為穿孔防火材之複合層合物的具體實施例係表示於圖2中。關於圖2，一複合層合物20包含兩層可撓曲防火毯材料21夾在一耐高溫金屬層22與一絲網層23之間。然後將鋁箔24黏接在該絲網層23上以產生該複合層合物20。 Therefore, another specific embodiment of the present invention as a composite laminate of a perforated fireproofing material is shown in Fig. 2. With respect to FIG. 2, a composite laminate 20 comprises two layers of flexible fire resistant carpet material 21 sandwiched between a refractory metal layer 22 and a screen layer 23. Aluminum foil 24 is then bonded to the screen layer 23 to produce the composite laminate 20.
