Even if wool, which is a natural fabric, is used alone or in a blend,
It is known to produce toxic combustion by-products. Significant efforts have been made to improve flame retardant technology for fabrics. Such techniques, for example, use flame retardants, such as halogenated compounds, to prevent flames from spreading to the fabric.

Block layers of silicone foam are used in practice in the form of a single layer adhered to the surface of a sleeve encasing the combustible material beneath the fabric or a flammable substructure beneath the fabric.

Aryl group, vinyl group and 3-8 carbon atoms

100 centipoise and present at least 0.2 moles of SiH per mole of water], and (e) 1-250 ppm of platinum catalyst. The basic vinyl-containing polymer preferably contains only vinyl end units, but may contain vinyl on the chain units. For hydride polymers, the polymer must have hydrogen atoms on the polymer chain in order to produce the proper form. However, in addition to hydrogen atoms on the chain, terminal hydrogen atoms may also be present. Hydride polymers cannot be used as crosslinking agents simply because they have terminal hydrogen atoms. As stated above, the composition must have at least 0.2 moles of hydrogen per mole of water in the hydride-containing polysiloxane crosslinker to release sufficient hydrogen to produce a suitable foam.

号に詳しく説明されている。 To form a foam using the composition described above, the components described above may be mixed and reacted primarily in two reactions. In the first reaction, hydrogen gas is produced by the reaction between water and the hydride polymer, causing the composition to foam. In the second reaction, the composition is cured into a silicone elastomer by reaction of the vinyl functionality with the hydride polymer. Of course, adding heat causes the reaction to proceed at an extremely rapid rate. This silicone foam composition is disclosed in U.S. Patent No. 4,189,545.
It is explained in detail in the issue.

Contains platinum catalyst. The organohydrogensiloxane and hydroxylated organosiloxane should be present in sufficient amounts to provide a molar ratio of silicon-bonded hydrogen atoms to silicon-bonded hydroxyl groups of 2.5-40.

蔵すべきでない。 The components of any of the silicone foam compositions described above can be mixed in accordance with conventional methods. For example, a hydride polymer or organohydrogensiloxane can be mixed with a platinum catalyst and then mixed with the basic vinyl-containing polymer and water or hydroxylated organosiloxane.
Alternatively, it is also suitable to first mix the platinum catalyst with the basic vinyl-containing polymer and water or hydroxylated organosiloxane and then with the hydride polymer or organohydrogensiloxane. Other methods of mixing are also suitable, such as dividing the vinyl-containing polymer and water or hydroxylated organosiloxane into two parts, mixing the first part with the platinum catalyst, and mixing the second part with the hydride polymer or organohydrogen. Mix with the siloxane and then blend both mixtures to form a foam. Various optional materials, such as silica filler, can be suitably mixed with one or more of the essential components.
These "packages" of ingredients can be any combination of ingredients provided that premature reactions do not occur until all ingredients are mixed. For storage purposes, hydride polymers or organohydrogensiloxanes should not be stored in "packages", ie, in mixtures with platinum catalysts, because of the risk of gas evolution.

ランの加水分解によつて製造することができる。 To control the simultaneous foaming and curing reactions, platinum catalyst inhibitors such as polymethylvinylsiloxane cyclic compounds and acetylenic alcohols can be added. Platinum catalyst inhibitors are well known in the art and are available in many varieties. However, these inhibitors must not interfere with foaming and curing to the extent that the foam products of this invention are impaired. The mixture should be placed at the desired site of use immediately after mixing its components. Foaming will begin immediately unless a platinum catalyst inhibitor is used to extend the pot life and allow the components to be mixed before being placed at the desired site of use. Inhibitors may be present in relatively small amounts, such as up to 2 parts by weight of a polymethylvinylsiloxane cyclic compound, to control the onset of foaming and curing. Polymethylvinylsiloxane cyclic compounds are known in the art and can be prepared, for example, by hydrolysis of methylvinyldichlorosilane.

のフオームが生成するものとする必要がある。 In making the articles of the present invention, a silicone foam composition is applied to at least one side of the fabric and foamed. For best results, the silicone foam composition is formulated to have a viscosity of less than 1,000,000 centipoise at 25°C, preferably with a viscosity in the range of about 500-100,000 centipoise at 25°C. The purpose of controlling viscosity is to control penetration into the fabric and to better form air bubbles in the foam. Although the fabric can be completely impregnated with the composition to create a foam on both sides, for most applications one side of the fabric is kept intact and only partially impregnated, i.e., the composition adheres to one side of the fabric. It is desirable to have only sufficient penetration. In addition, the formulation and foaming conditions are such that the density is approximately
0.08-0.4g/ cm3 , preferably about 0.16-0.32g/ cm3
The form must be generated.

フオームの厚さは、約６−約51mmである。 The silicone foam composition is applied to the fabric by any known method, such as by roller or blade.
Generally, enough silicone foam composition should be applied to provide a foam thickness of about 1.5 mm or more on one side of the fabric. Thicknesses greater than this provide little fire protection to the light fabric. The thickness of the foam should be increased depending on the thickness of the fabric, the weight of the fabric, and the desired degree of fire protection. Typical foam thicknesses used in most fabric applications, such as seat coverings, range from about 6 mm to about 51 mm.

る。 A method for applying silicone foam compositions to fabrics involves passing two impermeable films, such as polyolefin films, through a nip formed by two rollers such that both polyolefin sheets are in contact with or adjacent to each other. Preferably, a layer of fabric is passed with the silicone foam composition through the nip formed where the silicone foam composition is applied. The resulting silicone foam naturally has a polyolefin backing. The use of an impermeable film inhibits hydrogen gas from escaping and also prevents the silicone foam composition from sticking to the roller.

面温度はもつと高くてもよい。 Foaming of the composition can be promoted by applying heat. If the foaming action is too strong, the bubbles will not form properly and the foam will become irregular. However, heat can be used not only to speed up production, but also to control the penetration of silicone foam compositions into fabrics. Heat may be applied by convection or radiation. The temperature inside the foam is approximately 65℃
However, the furnace temperature and foam surface temperature may be higher.

These fillers include fumed silica, diatomaceous earth, zinc oxide, calcium carbonate, quartz powder, and the like. The maximum amount of filler added depends on the desired properties of the foam. Generally, up to about 60% by weight filler can be used.

Preferably, 0.52-2 weight can be added to increase the heat resistance of the foam. When carbon black is used, the foam self-extinguishes within a short period of time.
