Abstract

The invention relates to the field of synthetic leathers, and concretely relates to a silicone rubber synthetic leather and a production technology thereof. The silicone rubber synthetic leather comprises a surface rubber layer, a bottom surface layer and a substrate from top to bottom; the surface rubber layer comprises, by mass, 0.1-60% of poly(methylhydrogensiloxane), 1-20% of polyvinylsiloxane, 0.1-20% of silica, 0.1-10% of vinyl silicone resin, 0.01-1% of a platinum catalyst, 0.001-0.1% of an inhibitor and 0-0.1% of a color paste; and the bottom rubber layer includes, by mass, 0.1-80% ofpoly(methylhydrogensiloxane), 0.01-1% of polymethylsilsesquioxane, 1-20% of polyvinylsiloxane, 2-8% of trimethylchlorosilane, 0.01-1% of the platinum catalyst, 0.001-0.1% of the inhibitor and 0-0.1% of the color paste. The silicone rubber synthetic leather has the advantage of good wear resistance, good flame retardation property, good antifouling property, good hydrolysis resistance, high stability, high safety, small environmental pollution and beautiful appearance.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to silicone rubber synthetic leather and a production process thereof. Background technique [0002] Synthetic leather refers to a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. It is usually made of impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. Widely used in making shoes, boots, bags and ball games. [0003] At present, synthetic leather is mostly made of TPU, PU, ​​PVC and other surface layers. However, the wear resistance, flame retardancy, antifouling, hydrolysis resistance, stability and safety of these materials are not ideal, and these The raw materials of the materials are harmful to...
