Abstract
A stainproof, flame-resistant composite sheet material including at least one silicone polymer layer containing a silicon resin or rubber and optionally a flame-resistant inorganic filler and at least one stainproof surface layer containing at least one synthetic thermoplastic stain-resistant, weathering-resistant polymeric material, the silicone polymer layer and the stainproof surface layer being bonded optionally through an adhesive material, a cold plasma or corona discharge-modified surface portion of the silicone polymer layer or a cold plasma or corona discharge-modified and graft polymerization-modified surface portion of the silicone polymer layer.
Claims16
An improved composite sheet material comprising:
- (a) at least one stainproof surface layer containing at least one synthetic thermoplastic polymeric material having a high stain-resistance and weathering resistance selected from the group consisting of polyacrylic polymer resin materials and fluorine-containing polymer resin materials;
- and
- (b) at least one silicone polymer layer containing at least one member selected from the group consisting of silicone resins and silicone rubber, and having a surface portion thereof modified by means of a corona discharge treatment, through which resultant corona discharge-treated surface portion, the silicone polymer layer is bonded to the stainproof surface layer.
