Abstract

The present invention discloses a polybutylene terephthalate composite material and a preparation method therefor. The polybutylene terephthalate composite material is prepared by using the following components in parts by weight: 80-88 parts of polybutylene terephthalate, 15-25 parts of polyamide fiber, 8-14 parts of polyalkylene glycol, 5-8 parts of barium metaborate, 4-6 parts of styrene oxide, 3-8 parts of amino acid phenyl ester glycidyl, 2-4 parts of methyl isobutyl ketone, 1-2 parts of amino hydroxy ethyl diethylenetriamine, 1-2 parts of zirconium dioxide, 1-2 parts of diphenylamine and 0.5-2 parts of polydimethylsiloxane quaternary ammonium salt. The present invention also provides the preparation method for the polybutylene terephthalate composite material.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a polybutylene terephthalate composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT), also known as polytetramethylene terephthalate, is a polyester made by polycondensation of terephthalic acid and 1,4-butanediol. PBT is milky white translucent to opaque, semi-crystalline thermoplastic polyester. [0003] Polybutylene terephthalate is a common general-purpose resin. It has good comprehensive properties, is not resistant to strong acids and alkalis, can resist organic solvents, and is easy to decompose at high temperatures. However, due to its excellent performance, it is widely used in the fields of automobiles, home appliance shells, mechanical equipment, precision instrument parts, electronic appliances, textiles, etc., but in the process of use, PBT materials need to have certain mechanical strength and relatively...
