Problems solved by technology

However, due to the presence of benzene rings, ester groups and methylene groups in the PBT molecular structure, the PBT molecular chain is relatively rigid and has a high crystallization rate, resulting in low notched impact strength and poor flame retardancy of PBT materials.
With the development of society and human beings' emphasis on environmental protection, due to the large amount of smoke generated by halogen-containing flame retardants during combustion, and the release of toxic and corrosive gases that seriously endanger human health and do not meet environmental protection requirements, halogen-containing flame retardants PBT materials for fuel are restricted in many products

Abstract

The invention discloses an anti-impact environment-friendly flame-retardant polybutylene terephthalate composite material, comprising the following components by mass percent: 45-60% of polybutylene terephthalate, 18-25% of halogen-free flame retardant, 0.5-3% of anti-impact modifier, 5-40% of alkali-free glass fiber, 0.5-4% of silane coupling agent, 0.2-0.5% of antioxidant, 0.5-5% of flexibilizer, and 0.1-1% of lubricant. By adopting the anti-impact environment-friendly flame-retardant polybutylene terephthalate composite material, the impact resistance, the flame retardant property, the weatherability, the compatibility, the dispersing performance and the service life of polybutylene terephthalate are well balanced; the composite material is halogen-free and flame-retardant, free of poison, low in smoke and good in environmental protection property. Thus, the polybutylene terephthalate composite material with excellent overall performance is provided; the application field of polybutylene terephthalate is expanded.

Description

technical field [0001] The invention relates to a polybutylene terephthalate composite material, in particular to an impact-resistant, environment-friendly and flame-retardant polybutylene terephthalate composite material. Background technique [0002] Polybutylene terephthalate (PBT for short) is one of the five major engineering plastics and is widely used because of its excellent electrical properties and processing properties. However, due to the presence of benzene rings, ester groups and methylene groups in the PBT molecular structure, the PBT molecular chain is relatively rigid and has a high crystallization rate, resulting in low notched impact strength and poor flame retardancy of PBT materials. With the development of society and human beings' emphasis on environmental protection, due to the large amount of smoke generated by halogen-containing flame retardants during combustion, and the release of toxic and corrosive gases that seriously endanger human health and ...
