Abstract

The invention discloses a composite material and a preparation method thereof. The composite material is prepared from 50 to 80 parts by mass of polycarbonate resin, 10 to 35 parts by mass of ABS resin, 1 to 8 parts by mass of a compatible flexibilizer, 4 to 18 parts by mass of mineral powder, 2 to 8 parts by mass of a flow modifier, 1 to 5 parts by mass of color masterbatch, 0.1 to 1.5 parts by mass of metal powder, 0.1 to 1.5 parts by mass of pearl powder and 0.3 to 1.5 parts by mass of diffusion oil. The composite material is produced by blending raw materials according to a mass part ratio and carrying out melting granulation. Through use of the metal powder and pearl powder, alloy material colorful metal effects satisfy household electrical appliance product appearance and use requirements and the composite material has the advantages of scratch resistance, high hardness and environmental friendliness. The flow modifier can provide material flowability and improve the material injection molding performances. The micro / nano-silicate particles can improve the mechanical properties and gloss of the composite material and improve wear resistance of the composite material so that the composite material meets spray-free and high gloss appearance requirements.

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 a polycarbonate / ABS alloy material with a colorful metal effect, scratch resistance and high hardness, and a preparation method thereof. Background technique

[0002] Polycarbonate plastic (abbreviated as PC) is widely used in electronic appliances, automobiles, engineering and construction industries due to its excellent impact strength, toughness, heat resistance, transparency and easy coloring, and has become the five most widely used engineering plastics one. However, defects such as polycarbonate resistance to chemical stability and insufficient scratch resistance also limit its application in certain products.

[0003] Acrylonitrile-butadiene-styrene plastic (referred to as ABS resin) is one of the most widely used non-general plastics, with excellent impact resista...
