Abstract

The invention discloses a PC / ASA plastic for an automotive interior trim part and a production technology of the PC / ASA plastic. The production technology comprises following steps: (1), the raw materials are weighed in parts by weight; (2), the raw materials are mixed by a high-speed mixer for 5-15 min at a rotating speed of 300-900 r / min, and a mixed material is obtained; (3), the mixed materialis added to a twin-screw extruder for melt blending, and an extruded material is cooled, dried and diced, and the PC / ASA plastic is obtained. The PC / ASA plastic for the automotive interior trim partis prepared from PC and ASA as resin matrixes by selecting specific components and ratio, and production processes are simple, easy to control, low in cost and suitable for industrial production; thePC / ASA plastic has excellent wear resistance and mechanical performance and higher machinability, facilitates filling formation of a large die, and can be applied to various automotive interior trim parts and the like.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a PC / ASA plastic for automotive interior parts and a production process thereof. Background technique [0002] Automotive interior parts mainly include compartment partitions and door interior decoration. Dashboard assembly, armrest, top panel, carpet, seat and other parts, knitwear, felt, genuine leather, artificial leather, etc. In the manufacture of these devices for automotive use, this can be achieved through the use of metal products, wood products and plastic products. The use of wood products will increase the manufacturing price of automobiles, which is not conducive to the sales and promotion of automobiles, and can be used in high-end automobile manufacturing. The manufacture of metal products is relatively common in low-end automobile manufacturing, and the feel and comfort in use have certain limitations. The use of engineering plastics has changed th...
