Problems solved by technology

[0004] But generally speaking, the soles made of conventional polyurethane elastomer materials will be severely worn and the slip resistance will deteriorate after two or three years of use, which is not suitable for wearing.
[0005] For the related technologies mentioned above, the inventors found that the wear resistance of polyurethane elastomer materials needs to be improved

Abstract

The invention relates to the field of wear-resistant materials, and particularly discloses a polyurethane elastomer material as well as a preparation method and application thereof. The polyurethane elastomer material is prepared from the following raw materials: polyester polyol and / or polyether polyol, isocyanate, a foaming agent, a chain extender, silicon nitride and modified montmorillonite, the modified montmorillonite is obtained by organically modifying common montmorillonite with acrylamide; the preparation method comprises the following steps: mixing and stirring the polyester polyol and / or polyether polyol and isocyanate to obtain a mixture, mixing and stirring the remaining raw materials to obtain a mixture, adding the mixture into the mixture while stirring to obtain a base material, banburying the base material at 150-200 DEG C for 5-10 minutes to obtain a sizing material, and carrying out compression molding on the sizing material to obtain the polyurethane elastomer material. The polyurethane elastomer material provided by the invention has excellent wear resistance.

Description

technical field [0001] The present application relates to the field of wear-resistant materials, and more particularly, to a polyurethane elastomer material and its preparation method and application. Background technique [0002] Polyurethane elastomer materials have many excellent properties, such as high modulus, high strength, excellent abrasion resistance, chemical resistance, hydrolysis resistance, high and low temperature resistance and mildew resistance. These good properties make polyurethane materials widely used in many fields such as shoe materials, cables, clothing, automobiles, medicine and health, pipes, films and sheets. [0003] And the performance of polyurethane elastomer material is between plastic and rubber, oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness, elasticity, usually used as the raw material of wear-resistant soles and often used as the raw materials of wear-resistant soles. [0004] But generally s...
