Abstract

The invention discloses a POK / PET / PBT (polyketone / polyethylene terephthalate / polybutylene terephthalate) ternary alloy material, comprising, by mass, 20-30% of polyethylene terephthalate, 20-30% of polybutylene terephthalate, 10-20% of a polyketone, 1-5% of an antistatic agent, 5-10% of a halogen-free flame retardant, 0.1-0.5% of a compatibilizer, 0.2-0.8% of a lubricant, 1-5% of an antioxidant, 0.5-1% of a toughener, and 1-3% of an enhancer. A preparation process of the invention is simple, convenient to operate and control, good in quality, high in production efficiency, low in cost and suitable for large-scale industrial production; the POK / PET / PBT ternary alloy material has good toughness, corrosion resistance, wear resistance, oil resistance, impact resistance and the like, is environmentally friendly and flame retardant, and has good forming property; the POK / PET / PBT ternary alloy material made by means of blending with the antistatic agent has efficient and lasting static resistance; the toughness and hardness of the POK / PET / PBT ternary alloy material can be adjusted according to different needs.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a POK / PET / PBT ternary alloy material and a preparation process thereof. Background technique [0002] Polybutylene terephthalate (PBT) is a thermoplastic polyester developed in the 1970s. It has excellent mechanical, electrical, high temperature resistance, moisture resistance, chemical corrosion resistance, good electrical insulation performance, good elasticity, crystallization It has the characteristics of fast speed, good fluidity and easy forming and processing, and can maintain good mechanical properties in a wide temperature range. Due to the unique properties of PBT products, PBT engineering plastics and various alloys are widely used in electronic appliances and household appliances. It is an indispensable new material in various fields such as automobile, machinery, instrument, light textile and civil use. With the progress of science and technology and the de...
