Problems solved by technology

[0005] 1) The addition of metal powder will improve the metal texture of the product, but during the flow process, due to the orientation, it is easy to cause weld lines, so the coating technology and amount of metal powder are the key factors affecting the use of the product;
[0006] 2) ASA resin is a ternary graft copolymer composed of acrylonitrile-styrene-acrylate, which has low scratch resistance and cannot be used directly as a product appearance part;
[0008] There is no combination of ABS resin and PMMA resin in the existing composite materials to produce a colorful metal effect, and it does not have scratch resistance and high hardness, and there is no preparation method for preparing composite materials

Abstract

The invention discloses a composite material and a preparation method thereof. The composite material comprises the following raw materials in parts by mass: 10-50 parts of ASA resins, 50-80 parts of PMMA resins, 5-20 parts of compatible flexibilizers, 2-6 parts of color master batches, 0.1-5 parts of metal powder, 0.1-2 parts of pearl powder, 0.5-2 parts of lubricating agents and 0.2-0.6 part of antioxidant. The composite material is prepared by blending, fusing and pelletizing the raw materials in parts by weight. The metal powder and the pearl powder are added into the composite material, so that the colorful metal effect of the alloy material can meet the appearance use requirements of household appliances and the composite material has the advantages of scratching resistance, high hardness, excellent environmental protection property, no spraying glazing, and the like; the lubricating agents have excellent lubricating property, capability of reducing surface tension, capability of reducing friction and capability of enhancing glossiness; the micro-nano silicate particles can improve the mechanical property and glossiness of the composite material and can enhance the wear-resisting property of the material, so that the composite material can meet the requirements for spraying-free and high-gloss appearance of the products.

Description

technical field [0001] The invention relates to the technical field of modification of polymer engineering plastics, in particular to a composite material and a preparation method thereof, in particular to an ASA / PMMA alloy material with scratch resistance and imitation metal texture effect and a preparation method thereof. Background technique [0002] The national strategy of sustainable development requires industrial production to do its utmost to achieve energy conservation and emission reduction. Therefore, the development and manufacture of low-carbon energy-saving products has become a hot spot in the industry and research institutes. At present, metal imitation plastics are mostly prepared by spraying metal paint, electroplating, varnishing, IMD / IML and other processes. Compared with the traditional metal imitation effect achieved by spraying technology, spray-free high-gloss imitation metal materials are energy-saving, emission-reducing, green It has the advantages...
