Embodiment Construction

[0022] A polyurethane for sports shoe soles, comprising two components: component A, component B and filler, the weight ratio of the three being 1:1.7~1.86:0.1~0.3;

[0023] The component A mainly includes the following components by weight: 50-70 polyester polyols, 20-50 polymer polyols, 10-30 functional polyols; wherein the functional polyols are selected from 1-4 butanediol , 1-2 propylene glycol, 1-6 hexanediol or trimethylolpropane;

[0024] The component B mainly includes the following ingredients in parts by weight: 30-60 parts of diphenylmethane diisocyanate, 21-50 parts of polyester polyol, and 20-40 parts of isophorone diisocyanate;

[0025] The filler is dimethoxyethyl phthalate.

[0026] The above-mentioned polyurethane used for sports shoe soles is mainly composed of two mixture components: component A and component B, which are formed by mixing in a reasonable proportion, which can make the hardness of the material reach an excellent state and provide extremely ...
