Antistatic and ultraviolet resistant PC/ASA material composition

Abstract

The invention discloses an antistatic and ultraviolet resistant PC / ASA material composition and belongs to the field of macromolecular composition materials. The composition is characterized by consisting of the following components in part by weight: 30 to 85 parts of polycarbonate, 5 to 30 parts of acrylonitrile-styrene-acrylic ester graft copolymer, 0 to 30 parts of acrylonitrile-styrene copolymer, 5 to 15 parts of macromolecular antistatic agent, 2 to 10 parts of compatilizer, 0.2 to 2 parts of light stabilizer and 0.2 to 1 part of antioxidant. The interior plastic parts of an automobile, which are made of the PC / ASA composition of the invention, have the advantages of high weather resistance, ultraviolet resistance and heat resistance, difficult adsorption of dust and the like, and can be used for manufacturing interior-exterior parts, such as automotive door plates and shells of inner-outer view mirrors, of various automobiles.

Description

technical field

[0001] The invention relates to a polycarbonate (PC) / acrylonitrile-styrene-acrylate (ASA) composition, specifically an antistatic and anti-ultraviolet PC / ASA material composition, belonging to the field of polymer composite materials. Background technique

[0002] Polycarbonate (PC) plastic has the advantages of high heat resistance, good transparency, high gloss, good toughness, etc., but it has poor fluidity and difficult molding; the product is sensitive to gaps, not resistant to solvents, and prone to stress cracking.

[0003] There are many known methods for preparing PC plastic alloys to improve these shortcomings, wherein PC / ABS plastic alloys are the most common method, such as US Patent No. 3130177, US No. 4624986, etc., obtained by blending ABS and PC Low cost PC / ABS plastic alloy composition with high impact toughness and improved flow. However, the thermal stability and UV resistance of polycarbonate are often affected by the addition of ABS graf...
