High-strength high-temperature resistant PBT/PC alloy resin material and preparation method thereof

Abstract

The invention relates to a high-strength high-temperature resistant PBT / PC (Poly Butylenes Terephthalate / Polycarbonate) alloy resin material. The high-strength high-temperature resistant PBT / PC alloyresin material comprises the following various components by mass percent: 41%-51% of PBT resin, 16%-26% of PC resin, 30% of glass fiber, 0.2%-0.4% of an antioxygen, 0.6%-1% of superfine talcum powder, 0.3%-0.6% of an ester exchange inhibitor, 0.4%-0.6% of a lubricant and 0.45% of a toner, wherein the sum of the mass percent of the various components is 100%. The invention further provides a preparation method of the high-strength high-temperature resistant PBT / PC alloy resin material. The provided high-strength high-temperature resistant PBT / PC alloy resin material not only is high in strength, stable in size and excellent in creep resistance and mechanical property, but also is excellent in heat resistance, and meets the higher temperature resistance requirement of the special product. Meanwhile, the manufacturing process is simple, is high in benefit, is pollution-free, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a PBT / PC alloy resin material, in particular to a high-strength and high-temperature resistant PBT / PC alloy resin material and a preparation method thereof. Background technique [0002] PBT / PC alloy resin material. The alloy is obtained by blending polybutylene terephthalate (PBT) and polycarbonate (PC). Polybutylene terephthalate, the English name is polybutylene terephthalate (referred to as PBT), which belongs to the polyester series and is composed of 1.4-pbt butanediol (1.4-Butylene glycol) and terephthalic acid (PTA) or terephthalic acid It is a milky white translucent to opaque, crystalline thermoplastic polyester resin formed by polycondensation of dicarboxylate (DMT) and produced through a kneading process. PBT has high heat resistance, fatigue resistance, chemical resistance, rapid crystallization at low temperature, and good formability. The disadvantage is that the notched impact strength is low and the molding ...
