Abstract

The invention specifically relates to a preparation method for a high-impact-resistance high-flowability ABS resin, belonging to the technical field of high-molecular materials. The preparation methodcomprises the following steps: preparing ABS resin with high impact strength by using a DOW continuous bulk polymerization process, adding bulk ABS resin, SAN resin, a plasticizer, a lubricant and acompatibilizer in a certain mass ratio into a mixer for thorough mixing so as to obtain a mixed material; and then feeding the obtained mixed material into a twin-screw extruder for mixing, extruding,drawing, cooling and pelletizing so as to obtain the high-impact-resistance high-flowability ABS resin. The ABS resin prepared in the invention has superior impact performance; at the same time, thecompatibilizer is added during blending, so the compatibility between the ABS resin and the SAN resin is improved, the adhesion between the two polymers is increased, and a more stable structure is formed.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-impact high-flow ABS resin and a preparation method thereof. Background technique [0002] ABS resin is a polymer material formed by the copolymerization of styrene, acrylonitrile and butadiene, and has excellent comprehensive mechanical properties. In recent years, with the rapid development of the automobile and home appliance industries, ABS resin has developed towards the direction of high flow and high impact resistance. [0003] At present, there are two methods for preparing ABS resin, namely emulsion grafting blending method and continuous bulk method. The emulsion grafting blending method is the earliest method for industrialization of ABS resin. The particle size and distribution of latex in this method are highly controllable, and at the same time, graft powder products with high rubber content can be produced, but the production cost of ...
