Abstract

The invention relates to polyurethane synthetic leather resin with good color dispersion and high wear resistance, and a preparation method thereof. The resin is prepared by reaction of polyesterglycol, hydroxyl silicone oil, a small molecule chain extender, diphenylmethane diisocyanate, a hydroxyl component, vinyl silicone oil, hydrogen-containing silicone oil, a platinum complex catalyst and a solvent. The color dispersion property and wear resistance of the polyurethane synthetic leather resin both exceed those of a commercial product, and polyurethane synthetic leather manufactured from the polyurethane synthetic leather resin has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of polyurethane synthetic leather preparation, in particular to a polyurethane synthetic leather resin with good color dispersion and high wear resistance and a preparation method thereof. Background technique [0002] The application field of polyurethane synthetic leather involves all aspects of people's life, and has a broad market demand. The sports shoes, clothing, sofa furniture, car seats, decorative packaging materials, etc. produced with it as the main raw material have been increasingly recognized by the market. The wide application range, large quantity and variety are unmatched by many traditional textile materials and natural leather. With the increasingly fierce competition in the synthetic leather industry, people have higher and higher requirements for the performance of polyurethane synthetic leather products, especially the wear resistance. [0003] Since silicone resin has low surface ene...
