Abstract

The invention is suitable for the field of composite materials, and provides a high-CTI (Comparative Tracking Index), environment-friendly and flame-retardant reinforced PBT (Polybutylene Terephthalate) composite material and a preparation method of the high-CTI, environment-friendly and flame-retardant reinforced PBT composite material. According to 100 percent total weight, the high-CTI, environment-friendly and flame-retardant reinforced PBT composite material is prepared from the following components in percentage by weight: 40 to 55 percent of PBT, 20 to 40 percent of fiberglass, 3 to 8 percent of bromine-containing flame retardant, 8 to 14 percent of phosphor-containing composite flame retardant, 0.1 to 2 percent of polysiloxane, 2 to 5 percent of toughening agent and 0.1 to 1 percent of anti-oxidant.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a high-CTI environment-friendly flame-retardant reinforced PBT composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is a thermoplastic polyester with fast crystallization speed. It has the advantages of chemical corrosion resistance, excellent mechanical strength, and good processability. It is widely used in automobiles, electronic appliances, etc. industry. With the improvement of people's awareness of fire safety, the flame retardant modification of polymer materials used in automobile, electronic and electrical industries has become an inevitable demand. For a long time, flame retardant PBT modified engineering plastics usually use brominated flame retardants and antimony trioxide compounded. This system has high flame retardant efficiency and good flame retardant effect, but the relative tracking i...
