DMF-free and environmentally-friendly high performance silicone rubber polymer synthetic leather and manufacturing technology thereof

Abstract

The invention discloses a DMF-free and environmentally-friendly high performance silicone rubber polymer synthetic leather. The DMF-free and environmentally-friendly high performance silicone rubber polymer synthetic leather comprises a flame-retardant base, and the flame-retardant base is sequentially coated to form a DMF-free and environmentally-friendly high performance liquid silicone rubber layer and a DMF-free and environmentally-friendly high performance surface layer; and the DMF-free and environmentally-friendly high performance liquid silicone rubber layer comprises, by mass, 80-100parts of silicone rubber base rubber, 10-15 parts of low-viscosity vinyl silicone oil, 5-10 parts of vinyl MQ resin, 5-10 parts of hydrosilicone oil, 3-5 parts of a silane coupling agent, 1-3 parts ofa tackifier, 0.1-0.5 part of a platinum catalyst, 5-20 parts of a color paste pigment and 0.02-0.1 part of an inhibitor. The liquid silicone rubber is used as a raw material for manufacturing the synthetic leather, and no DMF is used in the production process, so the synthetic leather is harmless to human bodies or the environment, and has excellent resistance to flame, weather and hydrolysis. Aproduction technology of the synthetic leather has the advantages of simplicity, high production efficiency and low cost.

Description

technical field [0001] The invention relates to silicone rubber synthetic leather, in particular to a zero-DMF environment-friendly high-performance silicone rubber polymer synthetic leather and a manufacturing technology of the zero-DMF environment-friendly high-performance silicone rubber polymer synthetic leather. Background technique [0002] my country is a big producer of synthetic leather, accounting for about one-third of the world's output. From the production, consumption to export of synthetic leather, my country ranks first in the world. After nearly 50 years of development, the synthetic leather industry has become increasingly mature, and its production technology has also been greatly improved. It has replaced a large number of natural leather with insufficient resources, and is widely used in furniture, luggage, shoe materials, electronics and other fields. . [0003] At the same time, with the development of the economy and the increasing awareness of socia...

Problems solved by technology

[0004] However, the currently used synthetic leather is made of polyvinyl chloride (PVC) and polyurethane (PU), which produce a large amount of benzoate gas and DMF (N,N- Dimethylformamide) waste water has caused great harm to people's bodies and the environment, and the products have poor aging performance, no resistance to hydrolysis, poor wear resistance, etc., and cannot be used for a long time in the sun.
