Abstract

The invention provides a high-wear-resistance engineering plastic formula and a preparation method thereof, and relates to the field of engineering plastics. The high-wear-resistance engineering plastic is prepared from the following components in parts by weight: 60-70 parts of ammonium dimethylacetate, 20-30 parts of bis(4-aminophenyl)ether, 15-25 parts of pyromellitic dianhydride, 1-3 parts ofa dehydrating agent, 1-3 parts of a neutralizing agent, 10-20 parts of silicon dioxide glass fiber, 6-10 parts of polytetrafluoroethylene, 6-10 parts of molybdenum disulfide and 3-5 parts of a flame retardant. The silicon dioxide glass fiber, polytetrafluoroethylene and molybdenum disulfide are added during preparation of reasonably used raw materials, so that the high wear resistance of the engineering plastic is greatly improved, the service life of the engineering plastic is prolonged during use, and the flame retardance of the engineering plastic can be improved by adding the silicon dioxide glass fiber, polytetrafluoroethylene and molybdenum disulfide into the flame retardant during preparation of reasonably used raw materials. When the engineering plastic is used, the safety is improved, and unnecessary potential safety hazards caused by damage to the engineering plastic during combustion are prevented.

Description

technical field [0001] The invention relates to the field of engineering plastics, in particular to a formula of high wear-resistant engineering plastics and a preparation method thereof. Background technique [0002] Engineering plastics can be used as engineering materials and plastics that replace metal manufacturing machine parts, etc. Engineering plastics have excellent comprehensive properties, high rigidity, small creep, high mechanical strength, good heat resistance, and good electrical insulation. It can be used in the chemical and physical environment for a long time, and can replace metals as engineering structural materials, but the price is more expensive and the output is small. [0003] However, the flame retardancy and wear resistance of the current engineering plastics have not reached the best use effect. When used again, the engineering plastics are easily damaged due to high friction and the service life is reduced. When a fire occurs, the engineering pla...
