Abstract

The invention relates to a flame-retardant glass fiber reinforced polyethylene terephthalate (PET) / polytrimethylene terephthalate (PTT) / polybutylene terephthalate (PBT) alloy material and a preparation method thereof. The alloy material comprises the following raw materials in part by weight: 10 to 30 parts of PET, 10 to 30 parts of PTT, 20 to 40 parts of PBT, 3 to 10 parts of compatilizer, 5 to 20 parts of composite flame retardant, 0.1 to 0.5 part of antioxidant, 0.1 to 0.5 part of lubricating agent, and 10 to 30 parts of glass fibers. The preparation method comprises the following steps of: putting all the raw materials into an efficient mixer, mixing the raw materials for 5 to 10 minutes, and then discharging the uniformly mixed raw materials; and putting the uniformly mixed raw materials into a screw extruder, and performing extrusion and water cooling granulation. The produced PET / PTT / PBT alloy has the characteristics of excellent flame-retardant performance, high crystallization speed, good comprehensive physical and mechanical performance, low shrinkage rate, stable size, low warping, high surface glossiness, excellent processing performance and the like, and can be used for replacing a flame-retardant reinforced PBT material or bakelite under certain occasions.

Description

technical field [0001] The invention relates to a polymer material, in particular to a flame-retardant glass fiber reinforced PET / PTT / PBT alloy material and a preparation method thereof. Background technique [0002] PET (polyethylene terephthalate) is a crystalline polymer with high melting temperature and glass transition temperature, which maintains excellent physical and mechanical properties in a certain temperature range, and its fatigue resistance , friction resistance, aging resistance, and electrical insulation are extremely prominent, relatively stable to most organic solvents and acids, and have low production energy consumption, so they are widely used in the fields of synthetic fibers, films, and engineering plastics; but because PET Strong rigidity leads to poor toughness of the material, slow crystallization speed, high mold temperature and long molding cycle, etc., which greatly limit its application range. [0003] PTT (polytrimethylene terephthalate) is a ...
