Wood chip-containing polyurethane shoe material and preparation method thereof

Abstract

The invention discloses a wood chip-containing polyurethane shoe material and a preparation method thereof, belonging to the field of shoe materials. The wood chip-containing polyurethane shoe material is prepared from the following raw materials in parts by weight: 65-90 parts of polyester polyol, 65-90 parts of an isocyanate prepolymer, 2-4 parts of a catalyst, 1-50 parts of wood chips, 0-3 parts of a hardening agent, 1-30 parts of color paste and 0-2 parts of water. The preparation method of the shoe material comprises the following steps of: preheating 65-90 parts by weight of polyester polyol and 65-90 parts by weight of the isocyanate prepolymer in a charging bucket respectively according to a certain proportion; putting 2-4 parts by weight of the catalyst, 1-50 parts by weight of wood chips, 0-3 parts of the hardening agent, 1-30 parts of color paste, 0-2 parts of water, the preheated polyester polyol and the preheated isocyanate prepolymer into a mixing tank; stirring at a high speed; uniformly mixing and pouring a mixture into a shoe mold; and grinding a demolded shoe material to obtain a finished shoe material. The preparation method is used for preparing the wood chip-containing polyurethane shoe material.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to a polyurethane shoe material containing wood chips and a manufacturing method thereof. Background technique [0002] A shoe material in the prior art is made from raw materials such as polyester polyol, isocyanate prepolymer, catalyst, hardener, color paste and water, wherein polyester polyol and isocyanate prepolymer are used to make the shoe The main component of the material, and the amount of catalyst, hardener, color paste and water is small. Although the shoe material made of the above raw materials has good hand feeling, high elasticity and good dimensional stability, the appearance of this shoe material is monotonous, unattractive, not eye-catching, the decorative effect is poor, there is no sense of fashion trend, and it cannot bring people a sense of beauty or special visual effects. With the development of society and the improvement of people's material livin...
