Abstract

The invention relates to a wear-resistant composite material. According to the invention, ytterbium fluoride, thioacetamide and trimethylsilyloxy silicate are well mixed, such that a mixture is obtained; 1,3,5-triglycidyl-S-triazine trione and inorganic fiber are added into the mixture, and the mixture is stirred for 4h; an isocyanate curing agent is added, and the mixture is stirred for 2h under a temperature of 60 DEG C; a heat-resistant resin prepolymer and a high-viscosity resin prepolymer are added into the mixture, and the mixture is stirred for 6h under a temperature of 120 DEG C, such that a mold pressing composition is obtained; the mold pressing composition is placed into a mold, and is subjected to a mold pressing process with conditions of 150 DEG C/2h + 180 DEG C/1h, such that the wear-resistant composite material is obtained. With the preparation method provided by the invention, the sources of raw materials are wide; the preparation process is simple and controllable; and only conventional operations are required. Therefore, the method is easy to industrialize.

Description

technical field [0001] The invention belongs to the technical field of novel composite materials, and in particular relates to a wear-resistant composite material with high wear resistance. 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 traditional industries such as agriculture, chemical industry and building materials. There are many kinds of wear-resistant materials and they are widely used. A large-scale high-tech industrial group is being formed, which has very broad market prospects and extremely important strategic significance. [0003] According to statistics, the annual consumption of meta...
