Abstract

The application discloses a spray-free matte PC-ABS alloy material and a preparation method thereof. The spray-free matte PC-ABS alloy material is prepared from the following raw materials: PC, an epoxy compound, ABS, PMI, mica powder, an ultraviolet light absorber, a compatilizer, an antioxidant, a lubricant, calcium carbonate, carbon fibers, titanium oxide fibers, glass fibers, polyethylene glycol, EBS, MBS, HDPE, a flame retardant, PTT fibers and EVA; an epoxy functional group reacts with a terminal hydroxyl group of PC, so that the PC is branched or partially crosslinked, the relative molecular quality is improved, the concentration of the terminal group is reduced and the compatibility between the PC and ABS interface is also decreased before branching; macromolecular chain segments of the material begin to curl by adding mica powder for compounding, a free space is filled with inorganic mineral powder while the macromolecular chain segments curl, so that uneven convex micro-roughness of extrusion lines and extrusion particles of the material is realized; parts obtained by injection molding show low gloss characteristics, while inorganic minerals enable the material to have wear resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a spray-free matte PC-ABS alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is an engineering plastic with outstanding performance. It has high impact toughness, heat resistance, rigidity, creep resistance, and excellent dimensional stability, but its processing fluidity is not good; acrylonitrile -Butadiene-styrene copolymer (ABS) is an engineering plastic with excellent performance and wide application. It has excellent characteristics such as high impact strength and easy molding and processing, but it also has low heat resistance. PC / ABS alloy combines the respective advantages of PC and ABS, and its performance complements each other. It is widely used in machinery industry, automobile industry, electronic and electrical industry, instrumentation industry, textile industry and construction industry. However, the PC / A...
