Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a wear-resistant engineering plastic and its preparation method, which solves the phenomenon that the coating often falls off with the prolongation of the running time, and the wear resistance of the existing engineering plastic itself It is poor, and when the coating falls off, it will cause serious wear and tear on itself, thereby reducing the service life and increasing the cost of use. At the same time, the existing plastic preparation method will have more air bubbles during the plastic molding process, resulting in The yield rate of plastic is low, which leads to the problem of increased production cost

Abstract

The invention discloses a wear-resistant engineering plastic and a preparation method thereof. The wear-resistant engineering plastic is prepared from, by weight, 65-75 parts of unsaturated polyester,60-80 parts of polyethylene glycol terephthalate, 15-35 parts of semi-aromatic nylon PA6T, 10-12 parts of polytetrafluoroethylene, 10-20 parts of potassium titanate whisker reinforcement, 3-5 parts of a butyl tin mercaptide stabilizer, 1-5 parts of an additive, 0.6-1.8 parts of a coupling agent, 0.2-0.5 part of an antioxidant and 0.7-2.5 parts of a lubricant, and the lubricant is one or a composition of more of liquid paraffin, polyethylene wax and glyceryl monostearate. The invention relates to the technical field of engineering plastic products. The raw materials in the wear-resistant engineering plastic and the preparation method thereof are reasonably proportioned, the prepared engineering plastic is remarkable and durable in wear-resistant effect, excellent in mechanical property andbetter in effect of being matched with a polytetrafluoroethylene coating for use, and after the engineering plastic is prepared into engineering parts, the loss of the engineering plastic is small, and the performance change is small in a complex working environment.

Description

technical field [0001] The invention relates to the technical field of engineering plastic products, in particular to a wear-resistant engineering plastic and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It has medium resistance to deformation and is between fiber and rubber. Plastic is an important organic synthetic polymer material. Plastic has light weight, stable chemical properties, no rust, good impact resistance, good transparency, good insulation, and good coloring. And the advantages of low processing cost, etc., are widely used. Engineering plastics are a kind of plastics. Engineering plastics are engineering materials and plastics that replace metal manufacturing machine parts. Engineering plastics have excellent comprehensive properties, high rigidity, and creep resistance. Small, high mechanical strength, good hea...
