Antistatic organic-silicon synthetic leather and preparation method thereof

Abstract

The invention relates to an antistatic organic-silicon synthetic leather. The synthetic leather comprises a surface layer, a face layer, a bottom layer and a base material layer from top to bottom insequence, the surface layer is acrylamide hydrogel, and the face layer comprises, by weight, 15-65 parts of vinyl silicon resin, 10-25 parts of methyl vinyl silicone oil, 5-20 parts of a cross-linkingagent, 0.1-1.2 parts of a platinum catalyst, 0.01-0.4 part of an inhibitor, 5-25 parts of filler and 0-5 parts of color paste. The bottom layer comprises, by weight, 30-70 parts of base glue, 5-20 parts of vinyl silicon resin, 0.1-1.2 parts of a platinum catalyst, 0.01-0.4 part of an inhibitor, 5-15 parts of a cross-linking agent, 5-25 parts of filler and 0-5 parts of color paste. The prepared organic-silicon synthetic leather has the advantages of good antistatic, wear-resistant, scraping-resistant, scratch-resistant, soft and smooth performance, and dust suction can be reduced.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to an antistatic organic silicon synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather refers to plastic products that simulate the composition and structure of natural leather and can be used as its substitute material. At present, the elastic materials for producing synthetic leather are mainly polyurethane rubber (PU) and elastic polyvinyl chloride (PVC) sol, especially polyurethane Synthetic leather has the advantages of high strength, wear resistance, cold resistance, breathability, aging resistance, solvent resistance, soft texture, beautiful appearance, etc., and has good processing performance. It is an ideal imitation leather product to replace natural leather. Environmental hazards are likely to occur during the recycling process. With the gradual enhancement of people's awareness of environmental protection and safet...

[0002] Synthetic leather refers to plastic products that simulate the composition and structure of natural leather and can be used as its substitute material. At present, the elastic materials for synthetic leather are mainly polyurethane rubber (PU) and elastic polyvinyl chloride (PVC) sol, especially polyurethane Synthetic leather has the advantages of high strength, wear resistance, cold resistance, breathability, aging resistance, solvent resistance, soft texture, beautiful appearance, etc., and has good processing performance. It is an ideal imitation leather product to replace natural leather. Environmental hazards are likely to occur during the recycling process. With the gradual enhancement of people's awareness of environmental protection and safety, environmentally friendly and green products have become the target products for the development of various industries. Silicone synthetic leather can avoid the harm of traditional synthetic leather solvents to the environment and human body. At the same time, it has the properties of waterproof, anti-fouling, aging resistance, temperature resistance, hydrolysis resistance, and good hand feeling. It is an excellent substitute product for traditional synthetic leather. However, due to the insulation of silica gel itself, it is easy to accumulate static electricity and dust on the surface, which affects the use.
