Abstract

The invention discloses a flame-retardant and antistatic ABS modified resin, which comprises the following components in percentage by weight: 20 to 35 percent of ABS high glue powder, 35 to 60 percent of phenylethylene-acrylonitrile resin, 5 to 20 percent of bromine retardant, 2 to 6 percent of antimony retardant, 2 to 10 percent of antistatic agent, 0.1 to 1 percent of antioxidant and 0.2 to 1 percent of processing aid, wherein the total proportion of the components is 100 percent. On the basis of maintaining the good intrinsic impact resistance of an ABS resin, the ABS modified resin of the invention also has excellent flame retardance and antistatic property, is simple and easily operable in preparation process, can be widely applied to OA equipment and other industries having flame-retardant and antistatic requirements and has a wide application prospect.

Description

technical field [0001] The invention relates to an ABS modified resin, in particular to a flame-retardant and antistatic ABS modified resin, which belongs to the technical field of functional materials. Background technique [0002] ABS resin has the advantages of excellent low temperature resistance, impact resistance, chemical corrosion resistance, heat resistance, dimensional stability, surface gloss, small molding shrinkage, etc., and is widely used in household appliances, electronic and electrical products, office equipment, Industrial spare parts, automobile industry and many other fields. However, ABS resin is a flammable material. When it is recommended to be used in household appliances, electronic appliances and other fields, its flammability must comply with the relevant regulations of the American safety laboratory standard UL-94; especially important. Existing Chinese patent documents CN101463177A and CN1962751A respectively disclose brominated flame retardan...
