Problems solved by technology

[0004] To sum up, the potential application value of PET as an engineering plastic has aroused broad consensus in the industry. It is hoped that PET can be successfully included in the field of engineering plastics through various researches. Slower and higher cost, it is difficult to ensure that the performance of the material is relatively outstanding in all aspects, but only some of the performance characteristics have been improved, which affects the large-scale promotion and application of PET as engineering plastics

Abstract

The invention relates to a high-crystallization-rate flame-retardant enhanced polyethylene glycol terephthalate material and a preparation method thereof. The high-crystallization-rate flame-retardant enhanced polyethylene glycol terephthalate material is suitable for manufacturing shells of electronic and electrical appliances, electronic connectors of electric appliances, ignition coils, electrical and electronic relays and the like. The high-crystallization-rate flame-retardant enhanced polyethylene glycol terephthalate material comprises the following components in percentage by weight: 30.0 to 60.0 percent of polyethylene glycol terephthalate (PET) resin, 30.0 to 55.0 percent of reinforcing filler, 1.0 to 15.0 percent of a flame retardant, 0.1 to 5.0 percent of a nucleating agent, 0.1 to 5.0 percent of a lubricant, and 0.1 to 5.0 percent of an antioxidant, wherein the reinforcing filler is glass fiber. The high-crystallization-rate flame-retardant enhanced polyethylene glycol terephthalate material has the advantages of reasonable formula design, high crystallization rate, high injection molding processability and high mechanical properties.

Description

technical field [0001] The invention relates to a flame-retardant reinforced polyethylene terephthalate material with a high crystallization rate and a preparation method thereof. Background technique [0002] PET is a highly crystalline polymer with a smooth and glossy surface. It has good creep resistance, fatigue resistance, good friction resistance, low wear and high hardness; good electrical insulation performance, non-toxic, weather resistance, good chemical stability, low water absorption, and resistance to weak acids and organic solvents Advantages, especially the price of ethylene glycol used in the production of PET is almost half cheaper than that of butanediol used in the production of PBT, so PET resin and reinforced PET are the lowest prices in engineering plastics, with high cost performance. [0003] However, PET resin has a high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor di...
