Abstract

The invention provides solvent-free polyurethane interlayer resin and a preparation method and application thereof to sports casual shoe leather. The solvent-free polyurethane interlayer resin is composed of a component A and a component B according to the mass ratio of 100: 60-86.5, wherein the component A is composed of furan-modified polyether glycol, polyether triol, a chain extender, a foaming agent, a foam stabilizer, a foaming catalyst and a gel catalyst; and the component B is composed of aliphatic triisocyanate, aromatic polyisocyanate, polyether glycol and N-(2-hydroxyethyl)maleimide. The prepared solvent-free polyurethane interlayer resin can be applied to preparation of polyurethane synthetic leather for sports casual shoes. The prepared polyurethane synthetic leather for sports casual shoes has excellent environmental protection property, excellent hydrolysis resistance and low hand feeling fluctuation; especially after the later-stage embossing treatment, the finished product leather has clear lines and excellent hardness stability.

Description

technical field [0001] The invention belongs to the technical field of chemical products and preparation methods thereof, and relates to a solvent-free polyurethane interlayer resin and a preparation method thereof, and also relates to its application in polyurethane synthetic leather for sports and leisure shoes. Background technique [0002] Compared with animal leather, polyurethane synthetic leather is widely used in sports shoes of international brands such as Nike, Adidas, Puma, Skechers, Anta, and Li-Ning due to its light weight, high physical properties, and good waterproof performance. In recent years, in order to better improve the health and comfort of wearing products, international brand alliances have put forward higher and higher environmental protection requirements for upstream companies. Among them, polyurethane synthetic leather companies are faced with the need to provide N, N-dimethylformamide (DMFa) zero-content sports and leisure shoe leather products....
