The temperature control of each section of the main barrel (from the feeding port to the nozzle outlet) is 170°C, 200°C, 220°C, 230°C, 220°C respectively, and the twin-screw speed is 300 rpm. pellets to obtain the product. Above-mentioned product is injection molded into standard spline with plastic injection molding machine after being dried at 80 DEG C for 3 hours in blast oven, and injection molding temperature is 230 DEG C. The injection-molded strips were placed at 50% relative humidity at 23°C for at least 24 hours before performance testing. The actual test results are shown in Table 1.

Abstract

The invention discloses an ABS material with low gloss, high shock resistance, and high fluidity, which comprises a styrene-based resin, an ethane-acrylate copolymer elastomer, and a copolymer of gelated styrene and acrylonitrile; the amounts by weight of the components are 85-97 parts of the styrene-based resin, 1-10 parts of the ethane-acrylate copolymer elastomer, and 1-5 parts of the copolymer of gelated styrene and acrylonitrile. The ABS material prepared according to the ratio of the invention has low gloss, high shock resistance, and good processing fluidity, facilitates the filling and forming of large-size moulds, and is widely applicable to various automobile interior trimming parts and the like.

Description

technical field [0001] The invention relates to an ABS material, in particular to an ABS material with low luster, high impact resistance and high flow. It belongs to the field of modified plastics. Background technique [0002] In various applications of ABS materials, it is often required that the appearance of products made of this material have low gloss. For example, the appearance gloss of automotive plastic interior parts has a great impact on the performance and feel of automotive interior parts. Generally speaking, automotive original equipment manufacturers (OEMs) are willing to set a gloss target of 60 degrees. [0003] One of the methods to reduce the luster of the ABS material is to control the size of the rubber particles in the ABS resin. For example, US Pat. This method has a limited effect on reducing gloss. [0004] Other methods of reducing the gloss of ABS materials include the introduction of polyepoxides or gelled copolymers of styrene and acrylonitr...
