Problems solved by technology

[0004] In addition, synthetic leather composed of silicone leather (substrate + silicone resin or silicone rubber) has also appeared on the market, commonly known as silicone leather. Silicone leather products have excellent weather resistance (hydrolysis resistance, UV resistance, salt resistance, etc.) Fog), flame retardancy, anti-fouling and easy-care, waterproof, skin-friendly and non-irritating, mildew-proof and anti-bacterial, safe and environmentally friendly, etc., but due to the large amount of silicone materials used, the leather feels stiff, scratch-resistant and tear-resistant
Coupled with the high price of silica gel itself, the leather produced has not been able to be recognized by the market in large quantities.

Abstract

The invention relates to organic silicon resin, in particular to modified organic silicon resin and application thereof in polyurethane solvent-free decorative leather, furniture leather and automobile leather. The modified organic silicon resin is prepared from the following raw materials in parts by weight of 30 to 60 parts of organic silicon resin, 10 to 20 parts of polyether polyol, 10 to 30 parts of fumed silica, 10 to 40 parts of liquid silica gel, 0.01 to 0.5 part of platinum catalyst, 0.1 to 1 part of inhibitor, 10 to 40 parts of 1, 3-diethenyl-1,1,3,3-tetramethyldisiloxane, 5 to 20 parts of high-hydrogen-content silicone oil, 0.5 to 2 parts of anti-doodling additive and 1 to 5 parts of a hand feeling agent. Compared with pure silica gel leather, the product has the advantages that the scratch resistance is improved by 80%, the hand feeling of the leather is full, the cost is reduced by 50%, and the product performance exceeds that of solvent-free leather and pure silica gel leather.

Description

technical field [0001] The invention relates to a silicone resin, in particular to a modified silicone resin and its application in polyurethane solvent-free leather. Background technique [0002] Traditional leather mainly includes genuine leather, PVC leather (base + polyvinyl chloride) and oily PU leather (base + polyurethane). [0003] Solvent-free water-based PU leather (substrate + solvent-free resin + water-based resin) has appeared on the market in recent years. Its scratch resistance has reached more than 200,000 times in Martindale and Valspar. The manufacturing process is environmentally friendly, does not contain solvents, and has no harm to personnel. , high cost performance, but does not have special functions, except that it is better in environmental protection and scratch resistance, which is not much different from traditional leather. [0004] In addition, synthetic leather composed of silicone leather (substrate + silicone resin or silicone rubber) has a...
