Abstract

The invention discloses a high-strength wear-resistant composite material as well as a preparation method and application thereof. The high-strength wear-resistant composite material comprises glue and filler, wherein the glue comprises modified resin and a composite curing agent, the modified resin is at least one of E51 resin, NPEF170 resin and F51 resin which are blended and modified through hyperbranched polymers, the composite curing agent comprises a main curing agent and an accelerant, the main curing agent comprises at least one of a modified alicyclic amine curing agent and a modified aromatic amine curing agent, the accelerant is DMP-30, and the filler comprises SiC, Al2O3, PTFE, MoS2, graphite and SiO2. The high-strength wear-resistant composite material disclosed by the invention has the advantages of high strength, small pores, easiness in forming, oil resistance, acid and alkali resistance and high thermal stability, can meet various physical property requirements of machine tool body guide rails and base type guide rail parts on the composite material, and is low in comprehensive cost and good in shock absorption.

Description

technical field [0001] The invention relates to the field of wear-resistant materials, more specifically, to a high-strength wear-resistant composite material and its preparation method and application. Background technique [0002] The machine tool bed made of mineral castings has the advantages of shock absorption, integrity, thermal stability, chemical resistance and environmental protection of the production process. However, machine tool guide rails have high requirements for strength and wear resistance, and it is difficult for castings to meet the specific requirements of machine tool guide rails. After a long time of use, the casting machine tool guide rail will directly reduce the accuracy and service life of the machine tool. [0003] Therefore, how to provide a material that is suitable for machine tool guide rails and has high strength and good wear resistance has become a technical problem that needs to be solved urgently in this field.
