Abstract

The invention relates to the technical field of rubber gaskets, and in particular to a wear-resistant type gasket formula and a preparation method. The preparation method comprises the wear-resistanttype gasket formula and steps of plastication, mixing, preparation for vulcanization, compression moulding and vulcanization forming. The wear resistance and compressive resilience force of the rubbergasket are effectively increased, so that the gasket can play a better cushioning role in equipment.

Description

Technical field [0001] The invention relates to the technical field of rubber gaskets, in particular to a formulation and preparation method of wear-resistant gaskets. Background technique [0002] Rubber gaskets are used in many equipment to play a cushioning role, but the existing rubber gaskets have insufficient wear resistance and compression permanent deformation resistance, resulting in serious wear of rubber gaskets during use or insufficient resilience after being squeezed. The effect of earthquake. Summary of the invention [0003] The purpose of the present invention is to solve the shortcomings of insufficient wear resistance and compression permanent deformation resistance of rubber gaskets in the prior art, and propose a formulation and preparation method for wear-resistant gaskets. [0004] In order to achieve the above objectives, the present invention adopts the following technical solutions: [0005] Design a formulation and preparation method of a wear-resistant ga...
