Abstract

The invention provides a preparation method of a specular ABS (Acrylonitrile Butadiene Styrene) special material. The formula is as follows: ABS raw material with high melt index, toughening agent, PMMA (Polymethyl Methacrylate) and black color master; the toughening agent with mass fraction of 3-5% is used as reagent. The problem of white patches on the surface of a product is solved through formula material adjustment and earlier-stage processing of the materials, the improved formula can improve the material mobility and improve the glossiness (improved to 87), the melt index is improved by three times, and the material has high tensile strength improved by 1.2 times and high bending strength improved by 1.5 times compared with the standard of the customer.

Description

technical field [0001] The invention relates to a preparation method of a special ABS high-gloss material specially used for a TV base. Background technique [0002] ABS plastic is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size, and good surface gloss. It is easy to paint. , coloring, and secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bonding, etc. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles and construction. Wide range of thermoplastic engineering plastics. [0003] There are many ABS high-gloss materials on the market, including Zhenjiang Chimei and Japan Teijin, which are commonly used in the market; the products made are prone to white lines, or the surface o...
