Regenerated PA6/POK alloy reinforced wear-resistant material for automobile suspension plane bearing and preparation method of regenerated PA6/POK alloy reinforced wear-resistant material

Abstract

The invention belongs to the field of high polymer materials, and particularly relates to a regenerated PA6/POK alloy reinforced wear-resistant material for an automobile suspension plane bearing and a preparation method of the regenerated PA6/POK alloy reinforced wear-resistant material. The invention relates to the regenerated PA6/POK alloy reinforced wear-resistant material for an automotive suspension plane bearing. The composite material is prepared from the following components in percentage by mass: 15%-85% of polyamide regenerated PA6 resin, 20%-75% of polyketone POK resin, 4%-60% of glass fibers, 0.1%-40% of a compatilizer, 0.2%-10% of a wear-resistant agent, 0.2%-5% of a lubricant, 0.1%-2% of an antioxidant and 0.1%-5% of an anti-hydrolysis agent, wherein the sum of the components is 100%. PA66 is always used as a preferred material in the field of automobile suspension plane bearings, the PA6 material is more excellent in cold resistance and dimensional stability than PA66, is low in price and is recycled, and a regenerated PA6/POK alloy technology is used for adding a glass fiber filling amount to improve the tensile strength of the material and reduce the water absorption rate; meanwhile, by adding the compatilizer and the anti-hydrolysis aid, the impact strength is improved, the water absorption rate is reduced, the wear resistance and dimensional stability of a shock absorber plane bearing material in the market are met, a traditional polyamide PA66 material is replaced, and the production cost is reduced while the performance requirement is met.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a recycled PA6 / POK alloy reinforced wear-resistant material for automobile suspension plane bearings and a preparation method thereof. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Domestic aviation bearings, high-speed rail bearings, robot bearings, etc. are basically imported bearings. [0003] Bearing materials generally include metallic materials and non-metallic materials. What the present invention relates to is a kind of non-metallic macromolecular polyamide reinforced material, which is used for automobile lightweight to replace steel parts with plastic. [0004] The function of the plane bearing of the automobile suspension shock absorber is to act as a link ...

AI Technical Summary

Problems solved by technology

[0007] At present, there is no industrialized production device of adiponitrile in my country, and the demand for adiponitrile has always been dependent on imports; from June to November 2020, the price of PA66 raw materials will increase from 17,000 yuan / ton to 34,000 yuan / ton, and the supply and price increases will be interrupted from time to time. Prices caused the domestic related manufacturing industry to be overwhelmed
