Description

Technical field [0001] The invention relates to a polymer composite material, in particular to a flame-retardant reinforced warpage-resistant PBT / PTT alloy material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PBT) is one of the toughest engineering thermoplastic materials. It is a semi-crystalline material with very good chemical stability, mechanical strength, electrical insulation properties and thermal stability. Polytrimethylene terephthalate (PTT) is a newly developed electrode after polyethylene terephthalate (PET) in the 1950s and polybutylene terephthalate (PBT) in the 1970s. A promising new type of polyester polymer material has the advantages of good mechanical properties, good elasticity, abrasion resistance, insulation, and low water absorption. And because of the breakthrough in the industrial synthesis method of 1,3-propanediol, the raw material for the synthesis of PTT in recent years, the large-scale production of P...
