Abstract

The invention discloses flame-retardant engineering plastic and a preparation method thereof. The flame-retardant engineering plastic is prepared from, by weight, 30-40 parts of high density polyethylene, 30-40 parts of polyphenylene sulfide, 20-40 parts of polyethylene terephathalate, 10-20 parts of polytetrafluoroethylene, 10-20 parts of polypropylene, 15-20 parts of flame-retardant and fireproof quartz fiber packing, 10-20 parts of natural rubber, 5-8 parts of magnesium oxide, 6-8 parts of quartz fiber, 8-10 parts of modified polyphenylene oxide, 5-7 parts of diatomite, 3-5 parts of a halogen-free flame retardant, 2-4 parts of a lubricating agent, 1-3 parts of an antiager and 1-3 parts of a plasticizer. The engineering plastic prepared is remarkable and durable in effect, good in mechanical properties, effective in flame retardance, light in weight, high in strength and wide in market prospect in application and popularization of flammable environments.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant engineering plastic and a preparation method thereof. Background technique [0002] Engineering plastics are engineering materials and plastics that replace metals to make machine parts, etc. Engineering plastics have excellent comprehensive performance, high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time, and can replace metals as engineering structural materials. , but the price is more expensive and the output is smaller. Compared with general-purpose plastics, engineering plastics can meet higher requirements in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and are more convenient to process and can replace metal materials. Engineering plastics are widely used in ...
