Problems solved by technology

At present, sports shoe leather on the market mainly uses solvent-based polyurethane synthetic leather, and its processing method consists of two parts: wet process and dry process, which are determined by the characteristics of finished leather processing. The organic solvent N,N-dimethylformamide (DMF) used in the process is difficult to completely remove, resulting in a certain amount of DMF in the finished leather

Abstract

The invention belongs to the field of synthetic leather, and provides carbon fiber modified non-solvent polyurethane surface layer resin for sports shoe leather. The resin is formed by mixing a component A and a component B according to mass percent being 2:1 to 1:2, wherein the component A comprises 5 to 15 parts of aliphatic diisocyanate, 50 to 60 parts of low polymer dihydric alcohol, 10 to 20 parts of organosilicone polyhydric alcohol, 3 to 10 parts of micromolecule dihydric alcohol, 0.5 to 5 parts of micromolecule trihydric alcohol, 0.1 to 1.5 parts of a catalyst, 0.5 to 2.5 parts of a light / heat stabilizer, 0.02 to 0.5 part of a flatting agent, 0.01 to 0.2 part of a defoamer, 0.1 to 0.5 part of a dehydrator, and 0.5 to 5.0 parts of carbon fiber; the component B comprises 40 to 50 parts of aliphatic diisocyanate, 0 to 10 parts of triisocyanate, 35 to 50 parts of polytetrahydrofuran dihydric alcohol, 0.5 to 5 parts of micromolecule dihydric alcohol, 0 to 2 parts of micromolecule trihydric alcohol, and 0.5 to 1.0 part of a light / heat stabilizer. The invention further provides a preparation method and application of the resin. The tangential breaking strength of carbon fiber modified resin coating can reach 130kN / m or above; for non-solvent sports shoe leather prepared through the method, the peeling strength can reach 90N / 3 cm or above and the hydrolysis resistance can reach 10 weeks or above.

Description

technical field [0001] The technology belongs to the field of synthetic leather and relates to a carbon fiber modified solvent-free polyurethane surface layer resin for sports shoe leather and its preparation method and application. Background technique [0002] With the continuous improvement of living standards, people have put forward higher and higher requirements for the comfort, aesthetics and environmental protection performance of sports shoes. At present, sports shoe leather on the market mainly uses solvent-based polyurethane synthetic leather, and its processing method consists of two parts: wet process and dry process, which are determined by the characteristics of finished leather processing. The organic solvent N,N-dimethylformamide (DMF) used in the process is difficult to completely remove, resulting in a certain amount of DMF in the finished leather. [0003] The control of DMF content in finished leather by the European Union has also been tightened year b...
