Abstract

The invention relates to a high-light spray-free acrylonitrile-acrylate rubber-styrene terpolymer (ASA) / polymethyl methacrylate (PMMA) air-inlet grille special composite material and a preparation method thereof. The composite material consists of the following components in parts by weight: 20-40 parts of acrylonitrile-styrene (AS) resin, 35-45 parts of ASA high rubber powder, 35-45 parts of PMMAresin, 2-4 parts of modified metal powder, 0.5-1 part of an antioxidant and 1-2 parts of a lubricating agent. The composite material has the advantages that surface modification is carried out on themetal powder, so that the compatibility between the metal powder and the resin is improved, the overall fluidity of the material is improved, and flow marks formed in a material injection molding process can be effectively avoided while the comprehensive performance of the material is improved. According to the prepared high-light spray-free ASA / PMMA air-inlet grille special composite material, the excellent mechanical property, chemical oil resistance, weather resistance and processability of the ASA and PMMA materials are achieved, and the metallic texture is also achieved. Paint spraying treatment is not needed, so that the manufacturing efficiency of the automobile air-inlet grille is greatly improved, and the manufacturing cost is greatly reduced at the same time, so that the application prospect is very wide, and the composite material has a good economic value.

Description

[technical field] [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a composite material for a high-gloss spray-free ASA / PMMA automobile air intake grille and a preparation method thereof. [Background technique] [0002] With the continuous development of social economy, automobiles have entered thousands of households as a necessity of life, and people's requirements for automobiles have gradually increased, from a single functional requirement to the pursuit of cost-effective, aesthetics, environmental protection and other factors. The automobile air intake grille must not only meet its functional air intake and exchange requirements, but also take into account the new requirements of material and processing costs, stylish and beautiful appearance, and harmless to the environment and human body. At present, the air intake grille materials of major OEMs are mainly ABS and ABS / PMMA alloys, and the production materials are pai...
