Modified acrylonitrile-butadiene-styrene (ABS) resin with low glossiness and high performance

Abstract

The invention discloses modified acrylonitrile-butadiene-styrene (ABS) resin with low glossiness and high performance. The modified ABS resin comprises the following raw materials in parts by weight: 10-13 parts of polyvinyl chloride, 50-55 parts of modified ABS resin, 20-30 parts of glass fiber, 0.5-1.5 parts of a crosslinking agent dicumyl peroxide, 0.3-0.5 part of bi(3,5-tert-butyl-4-hydroxycyclohexyl phenyl) thioether, 0.3-0.5 part of thio-propionic acid diester, 0.1-0.5 part of tricresyl phosphate, 0.8-1.2 parts of zinc stearate, 2-4 parts of nanosilicon dioxide, and 4-6 parts of a compatibilizer ethylene-butyl acrylate copolymer, wherein the modified ABS resin is obtained by using N-phenylmaleimide-grafted ABS resin, and the filament diameter of the glass fiber is 5-15 microns. The modified ABS resin has excellent heat resistance, impact resistance and compatibility, good processability, good surface roughness and good extinction effect, and the bending strength and the bending modulus are also significantly enhanced.

Description

technical field [0001] The invention relates to the technical field of resins, in particular to a low-gloss high-performance modified ABS resin. Background technique [0002] ABS has a complex two-phase structure, that is, rubber phase and matrix resin, which combines the excellent properties of acrylonitrile-styrene copolymer and polybutadiene, and has good impact resistance, high surface hardness, dimensional stability, chemical resistance and It has excellent comprehensive properties such as good electrical properties, easy molding and mechanical processing, and is widely used in electronics, instrumentation, automobiles, etc. [0003] For many parts in the automobile and home appliance industries, such as automobile dashboards, integrated covers, grilles, electric water heater elements, and housings for heating appliances, etc., there are high requirements on the heat resistance and impact resistance of materials, while conventional ABS resins are subject to Due to the ...

Problems solved by technology

[0003] For many parts in the automobile and home appliance industries, such as automobile dashboards, integrated covers, grilles, electric water heater elements, and housings for heating appliances, etc., there are high requirements on the heat resistance and impact resistance of materials, while conventional ABS resins are subject to Due to the limitation of its own structure, it is difficult to maintain its good rigidity and hardness when the temperature is higher than 100°C, which makes the application of ABS resin slightly insufficient; and some parts in the optical field require a matting effect, and the general ABS resin is difficult to achieve
