The wear-resistant PET composite material is composed of PET, a wear-resistant material, an antioxidant and a lubricant, nano silicon nitride, polytetrafluoroethylene, a coupling agent A-151 and mica powder are mixed to prepare the wear-resistant material, the friction coefficient of the PET compositematerial can be greatly reduced by adding the wear-resistant material into the PET composite material, and the wear resistance of the PET 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 PET 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 Background technique [0002] With the advancement of lightweight and cost reduction, metals have been replaced by various composite materials.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 PET and polyether ether paulownia. [0003] Polyethylene terephthalate, the chemical formula is [COC 6 h 4 COOCH 2 CH 2 O] n . (English: Polyethyleneterephthalate, referred to as PET), by the transesterification of dimethyl terephthalate and ethylene glycol or the esterification of terephthalic acid and ethylene glycol to synthesize bishydroxyethyl terephtha...
