Problems solved by technology

[0003] The current technology mainly uses ordinary wear-resistant materials as linings or ceramic sheets, but the existing wear-resistant materials use ordinary epoxy resins, curing agents and fillers, which are easy to be brittle and have poor wear resistance, corrosion resistance and corrosion resistance. Poor temperature resistance, easy to generate heat due to friction, short service life of the coating, long repair process, and difficult repair of special-shaped areas, which cannot meet the needs of actual production

Abstract

The invention relates to the field of preparation of wear-resistant particulate rubbers, in particular to wear-resistant particulate rubber and a preparation method thereof. The wear-resistant particulate rubber comprises polysulfide rubber, phenolic epoxy resin, a modified curing agent, nano wear-resistant fillers, carbon fiber, zirconia ceramic fiber, and wear-resistant ceramic microspheres. Thepolysulfide rubber modifying technique is used herein such that the wear-resistant particulate rubber gains higher toughness and chemical resistance; phenolic epoxy resin helps improve the temperature resistance of the wear-resistant particulate rubber; the nano wear-resistant fillers and the ceramic fiber have high wear resistance; the organic mating of the materials having various performancesimparts the excellent properties of high toughness, resistance to high temperature, high wear resistance and corrosion resistance to the prepared wear-resistant particulate rubber.

Description

technical field [0001] The invention relates to the field of preparation of wear-resistant granular glue, in particular to a wear-resistant granular glue and a preparation method thereof. Background technique [0002] Wear-resistant materials are a large class of new materials with special electrical, magnetic, optical, acoustic, thermal, mechanical, chemical and biological functions. They are important basic materials for high-tech fields such as information technology, biotechnology, energy technology, and national defense construction. At the same time, it also plays a very important role in transforming some traditional industries. Wear-resistant particle glue is a high-performance wear-resistant polymer material obtained by compounding high-performance wear-resistant particles (zirconia, brown corundum, etc.) and modified toughened heat-resistant resin. The wear of equipment is also used to prepare wear-resistant coatings on the surface of parts with wear-resistant and...
