Abstract

The invention provides a highly wear-resistant polyurethane shoe material, which consists of the following parts by weight: 35-55 parts of polytetrahydrofuran, 25-45 parts of toluene diisocyanate, 5-15 parts of chain extender, and 2-5 parts of nano-silicon nitride , 0.5-2 parts of coupling agent, 0.2-1 part of heat stabilizer, 0.1-0.5 part of foaming agent, and 0.5-1 part of catalyst. The invention also discloses a manufacturing method of the high wear-resistant polyurethane shoe material. The polyurethane shoe material provided by the invention has better wear resistance.

Description

[0001] Technical field: [0002] The invention relates to a shoe material, in particular to a highly wear-resistant polyurethane shoe material and a manufacturing method thereof. [0003] Background technique: [0004] Polyurethane materials are usually prepared by reacting polymer polyols, isocyanates, chain extenders and a small amount of additives as raw materials. It is a high molecular polymer material between rubber and plastics and has good strength. , elongation, hardness, mechanical properties, etc., so it is widely used in various fields, and one of the conventional uses is as a shoe material for making various shoes. However, the wear resistance of ordinary polyurethane shoe materials is not good enough, and it has been unable to meet people's increasingly higher requirements on the wear resistance of shoe materials. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to provide a highly wear-resistant polyurethane sh...
