[Industrial Field of Application] The present invention relates to mat-reinforced silicone foam sheets. More particularly, the present invention relates to a silicone foam fire retardant sheet containing a non-combustible and non-melting reinforcing mat. BACKGROUND OF THE INVENTION Protective and insulating silicone foams are desired for many applications requiring flame retardancy. Today, silicone foams are effectively used as fire protection materials in electrical equipment, buildings, airplanes, automobiles, and furniture. Even if flame comes into direct contact with the silicone foam, the flame will be prevented from penetrating for a certain amount of time. That is, silicone foam tends to char at the point of flame or heat contact, creating a protective ash layer. Such a protective ash layer prevents flame from penetrating into the foam body, and as its thickness increases, it also inhibits decomposition and ashing of the silicone foam. Silicone foams can be used as films or sheets. Because such silicone foams have elastomeric properties, the sheets can be bent and stretched to conform to various shapes. However, the presence of sharp bends in silicone foam sheets creates stresses that can lead to cracking during oxidation and thermal decomposition. As a result, when a bend in a silicone foam sheet is exposed to flame, the surface oxidizes to a brittle silica, cracks form in the sheet due to stress at the bend, and flame penetration into the sheet. It will become. SUMMARY OF THE INVENTION One of the objects of the present invention is to provide a silicone foam sheet that exhibits improved resistance to flame penetration at bends (i.e. stress generating areas). It is also an object of the present invention to provide a silicone foam sheet that exhibits a reduced tendency to crack when subjected to stress in oxidative conditions. [Means for Solving the Problems] According to the present invention, the corner portion of the molded product is used for lamination on the molded product so that the corner portion thereof has improved resistance to flame penetration, and In a silicone foam sheet that can be bent at the corners, (a) it contains a residue of a platinum curing catalyst and is
an elastic silicone foam having a viscosity in the range of 100,000 centipoise; (b) a mat of woven, non-combustible and non-melting fibers of short fibers, comprising 1 x 10 -3 to 5 x 10 -1 g/ pine having a fiber content of cm 2 , silicone foam a is formed in a layer on one or both sides of pine b, and pine b
Provided is a silicone foam sheet, characterized in that it is partially or totally impregnated with silicone foam a. The silicone foam a used in the present invention is currently manufactured by two basic methods. Both methods are based on the simultaneous generation of hydrogen gas in situ and the simultaneous crosslinking of the silicone elastomer. Although less preferred, it is also possible to foam the silicone elastomer using a blowing agent. An example of a silicone foam composition suitable for use in the present invention is of formula (A)
