Abstract

The invention discloses a PBT material for automobile door handles, and a preparation method thereof. The PBT material comprises, by weight, 100 parts of PBT, 28-35 parts of ABS, 30-40 parts of EMA, 25-32 parts of a Ag<+> / SiO2 / TiO2 composite material, 6-12 parts of poly(p-dioxanone), 14-19 parts of sepiolite fibers, 1-2 parts of polyethylene glycol monooctadecyl ether, 9-11 parts of a compatilizer, 11-17 parts of a toughener, 8-15 parts of a filler, 2-7 parts of acoupling agent and 1-2 parts of an antioxidant. The PBT material prepared in the invention has the advantages of good mechanical properties, high rigidity and good antibacterial property, and is very suitable for being used as an automobile door handle material.

Description

technical field [0001] The invention relates to the field of PBT materials, in particular to a PBT material for automobile door handles and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is a crystalline linear saturated polyester resin with excellent mechanical, electrical, chemical corrosion resistance and low moisture absorption properties. It is a plastic with excellent comprehensive properties. PBT resin also has the advantages of easy crystallization and fast molding speed; good physical properties, high mechanical strength, stable size, good fatigue resistance, etc., and no double bonds in the molecular chain, excellent weather resistance and wear resistance. Therefore, PBT material has developed quite rapidly since its inception, and has been widely used in the fields of electronic appliances, automobile industry, machinery, instrumentation and household appliances. [0003] In recent years, the application of PBT materi...
