Problems solved by technology

[0016] But at present, the requirements for friction-resistant materials are getting higher and higher, so that they can still be used normally in harsh working environments, for example, under high load, high sliding speed, high temperature conditions, the material must also maintain a low friction coefficient and wear amount , and polyether ether ketone resin can not meet the requirements of harsh work change, therefore, it is necessary to modify polyether ether ketone to reduce its friction coefficient and wear amount, and to broaden the application range of polyether ether ketone

Abstract

The invention discloses a polyether-ether-ketone composite material, which is prepared from the following raw materials in percentage by weight: 90 to 96 percent of polyether-ether-ketone, 1 to 3 percent of nanometer diamond olefin and 1 to 7 percent of nanometer titanium dioxide P25. Meanwhile, a corresponding preparation method is provided. Nanometer diamond olefin and nanometer titanium dioxideP25 are added into a ternary composite material provided by the invention; the nanometer diamond olefin has no toxic and side effects on the human bodies, and has higher hardness, strong wear resistance and high stability; the friction factor and the abrasion rate of the composite material can be reduced; the nanometer diamond olefin and nanometer titanium dioxide P25 are added into the compositematerial and achieve the cooperated effects in aspects of lowering the friction factor and the abrasion rate; the prepared ternary composite material has low friction factor and low abrasion rate; the abrasion on the material is reduced; the service life of the wear-resistant material is prolonged; the thermal stability is high; the ternary composite material can meet the use requirement under the high-temperature harsh environment; the PEEK application is expanded.

Description

technical field [0001] The invention belongs to the technical field of engineering materials, and in particular relates to a polyether ether ketone composite material and a preparation method thereof. Background technique [0002] In human social activities, the main causes of material failure are friction and wear, fracture, corrosion, etc., and friction and wear cause material loss to account for 50%, that is, part of the energy has been wasted without being used. Furthermore, there are potential safety hazards in friction behavior. For example, in mines, frictional heat and sparks may cause fires or even explosions, resulting in accidents and losses; in the field of auto parts, damage to engines, shock absorbers, brakes, etc. is mainly caused by Friction causes, and if things go on like this, it may lead to the scrapping of the car; in the field of aerospace, it is not uncommon to see poor sealing or sparks due to corrosion resistance and friction, and then fuel explosion...
