Abstract

The invention discloses a heat-resistant and wear-resistant composite material and a preparation method and an application thereof and belongs to the field of high polymer wear-resistant materials. The heat-resistant and wear-resistant composite material is prepared from the following raw materials in parts by weight: 100 parts of thermoplastic resin, 10-40 parts of carbon fiber, 40-100 parts of a wear-resistant material, 0.1-1.0 part of a heat conduction material, 0.5-2.0 parts of a coupling agent, 0.2-1.0 part of an antioxidant and 0.5-5.0 parts of a lubricant. The heat-resistant and wear-resistant composite material has the characteristics of light specific gravity and high strength, the properties, such as the wear resistance, the corrosion resistance and the ageing resistance, are improved, and the heat-resistant and wear-resistant composite material is a composite material with excellent overall performance and can effectively replace metal alloy and ceramic materials.

Description

technical field [0001] The invention relates to the field of polymer wear-resistant materials, in particular to a high-temperature-resistant and wear-resistant composite material, a preparation method and an application. Background technique [0002] Wear-resistant materials are important basic materials for high-tech fields such as information technology, biotechnology, energy technology, high-end equipment, and national defense construction, and also play a very important role in transforming some traditional industries. Wear-resistant materials especially play an important role in the fields of automobile brake pads, aircraft brake materials, grinding wheels, ball mills, construction machinery mud pumps and mixer linings. [0003] Wear-resistant materials are divided into two categories, one is wear-resistant materials used as bearing sleeves, which require good lubricity and wear resistance; the other is used as friction materials, which require high hardness, high stren...
