Abstract

The invention provides a high-abrasion PU (Poly Urethane) shoe material comprising the following components in parts by weight: 25-40 parts of polyether polyol, 35-50 parts of toluene diisocynate, 5-10 parts of a chain extender, 2-6 parts of nanosilicon dioxide, 0.5-5 parts of silicon oil, 0.2-2 parts of water, 0.3-1 part of a crosslinking agent and 0.1-1 part of a catalyst. The invention also discloses a preparation method of the high-abrasion PU shoe material. The wear-resisting property of the PU shoe material provided by the invention is excellent.

Description

Technical field: [0001] The invention relates to a shoe material, in particular to a highly wear-resistant PU shoe material and a manufacturing method thereof. Background technique: [0002] Shoes are a necessity that is often used in people's daily life. The materials currently used to make shoes include rubber and plastics. A large category of rubber shoe materials is PU (ie polyurethane) shoe materials, which have the advantages of environmental protection, lightness, comfort, and non-deformation, so they occupy a larger market. However, the wear resistance of PU shoe materials is not high enough to meet people's higher and higher requirements on the wear resistance of shoe materials. Invention content: [0003] The technical problem to be solved by the present invention is to provide a highly wear-resistant PU shoe material with very good wear resistance. [0004] In order to solve the problems of the technologies described above, the technical solution of the presen...
