Preparation process of high-temperature-resistant and impact-resistant acrylonitrile butadiene styrene (ABS) particles

Abstract

The invention discloses high-temperature-resistant and impact-resistant acrylonitrile butadiene styrene (ABS) particles, which are prepared from the following raw materials in parts by weight: 50-70 parts of ABS resin, 5-15 parts of styrene-butadiene-styrene block copolymer (SBS) thermoplastic elastomer, 30-40 parts of polyphenylene sulfide (PPS), 2 parts of a foaming agent, 10 parts of impact-resistant powder, 1 part of a dispersing agent, 10 parts of a toughening agent and 20 parts of a coupling agent, wherein the coupling agent is prepared from a mixture of polylactic acid, acrylonitrile-butadiene-styrene and acrylic oligomers, the toughening agent is prepared from a mixture of methyl methacrylate-butadiene and styrene terpolymer (MBS), the MBS is prepared by polymerizing 42 parts (by dry mass) of styrene-butadiene latex, 28 parts of styrene and 30 parts methyl methacrylate in water, and the impact-resistant powder is prepared from a mixture of modified thermoplastic polyurethane (TPU) and polymethyl methacrylate (PMMA). The ABS particles produced by the process are obviously superior to the special engineering plastics commonly available on the market, and have very good impactresistance and high toughness while having good heat resistance and high temperature resistance, thus being suitable for a wider range of characteristics.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a process for preparing high-temperature-resistant and impact-resistant granule ABS. Background technique [0002] At present, the plastic industry is widely used in all walks of life. For the common plastic ABS on the market, most of them lack good high temperature and high heat resistance, low ductility and no impact resistance. They can only be used as conventional engineering plastics. For special projects such as electronics The application of electrical appliances, aerospace and other engineering applications is insufficient. Contents of the invention [0003] The object of the present invention is to provide a high-temperature-resistant and impact-resistant particle ABS preparation process to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A p...
