Abstract

The invention relates to a leather material, in particular to a leather material with wear-resistant and self-cleaning functions and application thereof. The leather material with the wear-resistant and self-cleaning functions is obtained by spraying, roll coating, brush coating or wipe coating a curable composition, wherein the curable composition comprises a component A and a component B; the component A is prepared from the following raw materials in parts by weight: 65-80 parts of polyaspartic acid ester resin, 4-8 parts of a silicon-fluorine copolymer, 1.5-1.8 parts of extinction particles, 15-20 parts of a solvent, 7-10 parts of a graphene compound and 1.2-5 parts of an auxiliary agent; the auxiliary agent comprises at least one of an antifoaming agent, a coalescing agent, a levelingagent and a wetting agent; and the component B is isocyanate. The curable composition disclosed by the invention can be well attached to leather, so that the leather has the excellent wear-resistantand self-cleaning functions, and the leather with the wear-resistant and self-cleaning functions can be applied to the fields of leather for living clothes, leather for furnishing and decoration, leather for furniture, leather for industrial manufacturing and leather for military industry.

Description

technical field [0001] The invention relates to a leather material, in particular to a leather material with wear-resistant self-cleaning function and its application. Background technique [0002] As a material with a long history, leather, whether it is natural leather or synthetic leather, is widely used in life, industry, and military industry. Therefore, people's requirements for leather are getting higher and higher. The cleanliness and Maintenance is often a big problem. For example, the tree paste leather is an environmentally friendly leather, which is made by adding natural resin by hand, and has a mellow tree fragrance; the surface has not been chemically treated, and there will be certain color differences. Collisions may cause scratches. Relatively poor against stains. Common oil stains are easy to penetrate and cannot be cleaned; the surface of oily skin has a certain cracking effect, natural wrinkling and discoloration, and the color of each part is differen...
