Wear-resistant composite material

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.

Problems solved by technology

In recent years, with the rapid development of the domestic economy, the demand for highways and the construction industry has been large, and the cement production has increased year by year. The cement industry has increased its output, and the property requirements of wear-resistant balls have also increased accordingly, from low chromium content to high chromium content, and even Wear-resistant balls with higher grinding efficiency need to be developed urgently. However, domestic wear-resistant ball manufacturers are mostly private enterprises with limited funds and insufficient technical research and innovation capabilities. It is difficult to create brands to improve product efficiency, and the gap with international standards is gradually widening.
