Abstract

The invention discloses a flame-retardant ultraviolet-resistant ABS (acrylonitrile-butadiene-styrene) modified resin which is composed of the following components in percentage by weight: 30-40% of ABS high rubber powder, 35-45% of styrene-acrylonitrile resin, 15-20% of bromine flame retardant, 5-6% of antimony flame retardant, 0.5-2% of anti-ultraviolet agent, 0.1-1% of antioxidant and 0.2-1% of processing aid. On the premise of maintaining the favorable impact resistance of the ABS resin, the ABS modified resin has the advantages of excellent flame retardancy and excellent ultraviolet resistance. The preparation technique is simple and easy to operate. The ABS modified resin can be widely used in accumulator case materials with requirements for flame retardancy and ultraviolet resistance, and has wide application prospects.

Description

Technical field [0001] The invention relates to an ABS modified resin, in particular to a flame-retardant and anti-ultraviolet ABS modified resin suitable for use in battery shells, and belongs to the technical field of functional materials. Background technique [0002] ABS resin has excellent low temperature resistance, impact resistance, chemical resistance, heat resistance, dimensional stability, surface gloss, and low molding shrinkage. It is widely used in household appliances, electronic and electrical products, office equipment, Industrial spare parts, automobile industry, battery casing 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; therefore, the flame retardant modification of ABS resin is particularly important important. The existing Chinese...
