Abstract

The invention relates to a PPO / PBT composite material used for industrial large-scale parts and a preparation method thereof. The composite material comprises the following components in terms of weight percentage: 30% to 55% of polyphenylene ether (PPO), polyparaphenylene Butylene glycol diformate (PBT) 8-25%, toughening agent 13.6-32%, compatibilizer 6-15%, antioxidant 0.2-0.8%, lubricant 0.2-0.6%, flame retardant 1-6 %. The invention improves the incompatibility between PPO and PBT materials due to the structure by adopting a suitable compatibilizer, and solves the defect of peeling of PPO / PBT composite materials in the injection molding process, and poor fluidity, which is difficult to form The defects of large parts greatly improve the comprehensive performance of PPO / PBT composite materials, making forming parts easier and more widely used, and the preparation process is simple and low cost, which can achieve good economic benefits.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PPO / PBT composite material used for large-scale industrial parts and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) is one of the world's five general-purpose engineering plastics. It has the advantages of high rigidity, high heat resistance, flame retardant, high strength and excellent electrical properties. In addition, polybenzyl ether also has the advantages of wear resistance, non-toxicity, and pollution resistance. The dielectric constant and dielectric loss of PPO are one of the smallest varieties among engineering plastics, and they are hardly affected by temperature and humidity, and can be used in low, medium and high frequency fields. The load deflection temperature of PPO can reach above 190°C, and the embrittlement temperature is -170°C. Unmodified polyphenylene ether (PPO) resin has good mechanical properties, el...
