Abstract

The invention relates to the field of PC composite materials, and particularly discloses a high-gloss and high-toughness PC composite material and a preparation method thereof. The high-gloss and high-toughness PC composite material comprises the following raw material components in parts by weight: 80-100 parts of PC; 30 to 45 parts of PMMA (polymethyl methacrylate); 9-12 parts of a toughening agent; 7-10 parts of a compatilizer; 1-3 parts of an antioxidant; the flexibilizer is prepared by mixing an acrylonitrile-styrene-butyl acrylate copolymer and an ethylene-octylene copolymer according to a mass ratio of (2-3): 1; the preparation method comprises the following steps: accurately weighing the raw material components according to the ratio, and uniformly mixing to obtain a mixture; and extruding the mixture, drawing into strips, cooling with water, and pelletizing to obtain the high-gloss and high-toughness PC composite material. The high-gloss and high-toughness PC composite material disclosed by the invention has the advantage of better impact toughness.

Description

technical field [0001] The application relates to the field of PC composite materials, more specifically, it relates to a high-gloss and high-toughness PC composite material and a preparation method thereof. Background technique [0002] PC (polycarbonate) has excellent elastic modulus, impact strength and high transparency, and low molding shrinkage rate. It has a wide range of applications in electronic appliances, industrial machinery parts, health equipment, etc. PMMA (polymethyl methacrylate) is a transparent thermoplastic polymer with excellent chemical stability and weather resistance. It is mainly used in advertising light boxes, lamps, daily necessities and furniture. By mixing PC and PMMA, a composite material with a certain degree of transparency and pearl luster can be obtained. Because of the beautiful appearance and excellent mechanical properties of the composite material, it has been more and more widely recognized and applied by people. [0003] With econom...
