Abstract

The invention discloses a wear-resistant ABS composite material and a preparation method thereof. The wear-resistant ABS composite material is composed of ABS, polyvinyl chloride, a wear-resistant material, an antioxidant and a lubricant. Nano molybdenum disulfide, polytetrafluoroethylene, coupling agent A-172 and mica powder are mixed to prepare the wear-resistant material, the friction coefficient of the ABS composite material can be greatly reduced by adding the wear-resistant material into the ABS composite material, and the wear resistance of the ABS composite material is obviously improved.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a wear-resistant ABS composite material and a preparation method thereof. Background technique [0002] With the advancement of lightweight and cost reduction, metals have been replaced by various composite materials. Compared with metal components, composite materials have poor wear resistance, resulting in a lower service life. At present, steering components in the fields of automobile engines, cylinder piston parts, textile machinery, mining machinery, etc. are all replaced by composite materials such as ABS and polyether ether paulownia. [0003] ABS resin refers to acrylonitrile-butadiene-styrene copolymer. ABS is the acronym for Acrylonitrile ButadieneStyrene. It is a thermoplastic polymer material with high strength, good toughness and easy processing. Used in the preparation of various parts such as instruments, electrical appliances, machinery, etc. In ord...
