Abstract

The invention discloses a high-strength electroplating PC/ABS alloy material and a preparation method thereof. The high-strength electroplating PC/ABS alloy material is prepared by comprising the following raw materials in parts by weight: 40-60 parts of PC, 40-60 parts of ABS, 5-10 parts of ABS-g-MAH compatilizer, 1-5 parts of GMA toughening agent, 0.5-1 part of nano calcium carbonate, 0.2-0.5 part of antioxidant 168, and 0.2-0.5 part of lubricant. By adding GMA toughening agent, and nano calcium carbonate in preparation of the PC/ABS alloy material, the modified PC/ABS alloy has higher tensile strength and bending strength, and the PC/ABS alloy material has excellent rigidity; the impact strength of the electroplating PC/ABS alloy material can be improved synergistically by the GMA toughening agent and ABS-g-MAH compatilizer, and the electroplating PC/ABS alloy material has impact toughness of excellent rigidity; and the electroplating PC/ABS alloy material added with GMA toughening agent and nano calcium carbonate does not influence the electroplating performance, and is especially applicable to automobile outer door electroplating handles and inner door electroplating clasping hands and other products which are frequently subjected to drawing force.

Description

technical field [0001] The invention belongs to a technical modification and method in the technical field of polymer materials, and in particular relates to an electroplating PC / ABS alloy material and a preparation method. 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 the problem of low heat resistance. PC / ABS alloy is a kind of engineering plastic modified by melt blending. It combines the advantages of PC and ABS, and its performance is complementary. Its melt viscosity, cost and processing performance are better than PC, and the in...
