Problems solved by technology

However, pure ASA is difficult to achieve the above effects. At present, in industrial production, PMMA is usually added to the ASA formula system to make an ASA / PMMA alloy to meet the requirements of high-gloss black.
[0003] But because of the density of PMMA (1.19~1.2g / cm 3 ) than the density of ASA (1.07g / cm 3 ) is large, adding PMMA to the ASA system will lead to an increase in material density, and the weight of the injection molded parts is heavy, which does not meet the current development trend of lightweight automobiles
At the same time, it is well known to practitioners in the industry that PMMA material is easy to decompose at high temperature, and at the same time, the melt viscosity is high and it is difficult to flow, which brings many difficulties to the molding process, resulting in low product yield.

Abstract

The invention discloses a black highlight ASA composite material and a preparation method thereof. The ASA composite material is mainly prepared from the following raw materials in parts by weight: 45-70 parts of AS resin, 5-60 parts of MS resin, 25-45 parts of high glue powder, 0.1-3 parts of black powder, 0.1-1 part of a lubricant and 0.1-2 parts of an anti-aging aid. Compared with the prior art, the fluidity of the material can be improved, the defect that the PMMA material is easy to decompose is avoided, injection molding of the material is facilitated, and the processability of the material is improved.

Description

technical field [0001] The invention discloses a black high-gloss ASA composite material and a preparation method thereof, belonging to the technical field of ASA composite materials. Background technique [0002] ASA is a terpolymer of styrene-acrylonitrile-acrylate. Compared with ABS, the weather resistance has been significantly improved due to the introduction of acrylate rubber without double bonds instead of butadiene rubber. It is about 10 times higher, while other mechanical properties, processing properties, electrical insulation and chemical corrosion resistance are similar to ABS. With the development of the automobile industry, ASA material is used because of its excellent weather resistance, chemical resistance and environmental stress crack resistance, it can withstand hot water treatment and detergent cleaning, and it can achieve a good surface effect without additional painting. It is widely used in automobile taillights, rearview mirrors, grilles, door pill...
