[0029] Prepare the raw materials of Examples 1 to 5 and Comparative Examples 1 to 2 according to the formula in Table 1, and prepare them according to the following steps. The dried ABS resin, heat-resistant agent, compatibilizer, damping reinforcement resin, antioxidant, After the lubricant is mixed, it is added to the main cylinder of the twin-screw extruder (the diameter of the screw is 35mm, and the length-to-diameter ratio L / D=48). The temperature control of each section of the main barrel (from the feeding port to the outlet of the machine head) is 220°C, 230°C, 240°C, 245°C, 240°C respectively, the twin-screw speed is 300 rpm, and the extruded material is cut after cooling in the water tank. grain.

Abstract

The invention discloses a high-damping noise-reducing ABS (Acrylonitrile Butadiene Styrene) resin composition. The high-damping noise-reducing ABS resin composition is prepared from 59.1 to 89.5 percent of ABS resin, 0 to 20 percent of heat-resisting agent, 5 to 15 percent of compatibilizer, 5 to 10 percent damping-enhancing resin, and 0.5 to 1.5 percent of assistant. By adopting the high-damping noise-reducing ABS resin composition, the damping performance of the ABS resin is improved, and a noise-reducing feature is realized through the high-damping resin; meanwhile, a proper compatibilizer is selected to improve the compatibility among co-blended resins; the prepared ABS resin composition has a high emission feature, superior mechanical performance and superior machining performance; the high-damping noise-reducing ABS resin composition is simple in preparation process, has low equipment requirements, is suitable for industrial production, and can be widely applied in the fields of automobiles and home appliances.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-damping and noise-reducing ABS resin composition. Background technique [0002] ABS (acrylonitrile-butadiene-styrene) is an acrylonitrile-butadiene-styrene terpolymer. Because the ABS resin coordinates the superior properties of the three components, it has excellent impact strength, good processing performance and chemical Stable, easy to mold, the product is glossy, and has both toughness and flexibility, and excellent comprehensive performance. ABS resin is widely used in the automobile industry, electronic and electrical industry, light industrial appliances, textile and construction industries due to its excellent comprehensive performance. In recent years, the automotive industry has paid more and more attention to the noise in the car. The noise in the car mainly comes from the extrusion of the joint parts in the car and the friction between the parts. ...
