Abstract

The invention discloses a wear-resistant and scraping-resistant injection-molding-grade PC / ABS alloy material. The wear-resistant and scraping-resistant injection-molding-grade PC / ABS alloy material is characterized by being prepared from, by weight, 35%-75% of PC, 15%-60% of ABS, 2%-5% of compound compatilizer, 1%-3% of compound toughening agent, 1%-3% of lubricating agent, 0.5%-1% of antioxidant and 0.5%-1% of anti-ultraviolet agent; a compound compatilizer is an interface compatilizer compounded by polyolefin elastomer (POE) and modified polyolefin in the compounding ratio of 1:1-1:3, the modified polyolefin is maleic-anhydride-grafted polypropylene (PP-g-MAH), and the grafting ratio ranges from 3% to 5%; a compound toughening agent is compounded by thermoplastic rubber, polyolefin and modified nanometer calcium carbonate. According to the wear-resistant and scraping-resistant injection-molding-grade PC / ABS alloy material, as the compound compatilizer is adopted, the compatibility between a PC interface and an ABS interface is greatly improved; as the compound toughening agent is adopted, the mechanical performance, the wear resistance and the scraping resistance of the alloy material are greatly improved. The wear-resistant and scraping-resistant injection-molding-grade PC / ABS alloy material can be widely applied to the field of the furniture appliance industry, the communication equipment industry, the electron industry and the like.

Description

technical field [0001] The invention relates to a polymer alloy material, more specifically, to a wear-resistant and scratch-resistant injection molding grade PC / ABS alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. It is a widely used polymer with excellent comprehensive properties. It has outstanding impact resistance, high heat resistance and Cold resistance, it is one of the most frequently used engineering plastics in recent years, and has a wide range of uses in optics, electronics, automobiles, construction, office equipment, packaging, telecontrol equipment, medical care and other fields. ABS plastic raw material resin (acrylonitrile-styrene-butadiene copolymer) is a thermoplastic polymer material structure with high strength, good toughness and easy processing. [0003] ABS and PC are two kinds of engineering plastics with e...
