一种PBT树脂和低熔点PET树脂组合物及其制备方法
摘要：
本本发明公开了一种PBT树脂和低熔点PET树脂组合物及其制备方法，该组合物包括组分：PBT树脂10份-87.4份；低熔点PET树脂10份-87.4份；增韧剂2份-30份；抗氧剂0.6份；其中，低熔点PET树脂是一种熔点在190-230℃特殊的PET树脂；增韧剂为乙烯-醋酸乙烯酯、乙烯-丙烯酸甲酯、乙烯-丙烯酸乙酯、乙烯-丙烯酸丁酯、低密度聚乙烯、马来酸酐接枝乙烯-辛烯共聚物、乙烯-丙烯酸乙酯-缩水甘油酯共聚物、乙烯-丙烯酸丁酯-缩水甘油酯共聚物至少一种。本发明通过优选低熔点PET树脂和增韧剂的种类和用量，制备得到的PET/PBT树脂组合物具有低熔点，高韧性等特点，可以广泛应用于注塑制品中。
摘要（英）：

The invention discloses composition of PBT resin and low-melting-point PET resin and a preparation of the composition. The composition comprises 10-87.4 parts of the PBT resin, 10-87.4 parts of the low-melting-point PET resin, 2-30 parts of toughening agent and 0.6 part of antioxidant, wherein the low-melting-point PET resin is special resin with the melting point being 190-230 DEG C; the toughening agent at least one of ethylene-vinyl acetate, ethylene-methyl acrylate, ethylene-ethyl acrylate, ethylene-butyl acrylate, low-density polyethylene, maleic anhydride grafted ethylene-octylene copolymer, ethylene-ethyl acrylate-glycidyl ester copolymer and ethylene-butyl acrylate-glycidyl ester copolymer. The composition and the preparation method thereof have the advantages that by preferably selecting the kinds and use amount of the low-melting-point PET resin and the toughening agent, the prepared PET/PBT resin composition is low in melting point, high in toughness, widely applicable to injection molding products, and the like.
