High temperature resistant special black special fog treatment agent for synthetic leather

Abstract

The invention discloses a high temperature-resistant super black and misty processing agent used for synthetic leather. The processing agent is prepared by mixing the following components by weight percent: 14-20% of toluene, 25-30% of ethyl acetate, 8-12% of isopropyl alcohol, 4-5.5% of extinction powder, 38-42% of aliphatic polyurethane resin, and 0.5-1% of polyethylene oxide wax. The processing agent discloses by the invention is good in high temperature resistance, coating performance, and stability, high in ultraviolet resistance, not easy to yellow, and used for coating the synthetic leather; the coated synthetic leather has a mist simulation effect on the surface, a good mist degree, a unique black visual effect, and full soft wax feeling in touch by fingers; when the coated synthetic leather is subjected to high temperature embossing, the black visual effect is not changed, and the soft wax feeling is stronger in touch by the fingers.

Description

technical field [0001] The invention relates to the technical field of leather treatment agent production, in particular to a high-temperature-resistant ultra-black and ultra-fog treatment agent for synthetic leather. Background technique [0002] At present, synthetic leather has largely replaced natural leather with insufficient resources to make bags, clothing, shoes, and decorations for vehicles and furniture. With the improvement of people's living standards and aesthetic tastes, synthetic leather products not only need to be durable, It should also have a good appearance and touch, which not only puts forward higher requirements for the polyurethane resin for the production of synthetic leather, but also puts forward higher requirements for the leather finishing agent. It is required that the light-colored leather will not turn yellow, matte, have a particularly black visual effect in the sun for a long time, and also have the waxy feeling of genuine leather. Therefor...

Problems solved by technology

Therefore, the synthetic leather treatment agent compounded by the original mature ordinary polyurethane resin can not meet the aesthetic requirements of consumers for hand feel and appearance, and needs more special and unique styles to meet customer requirements.
