Abstract

The invention discloses a flame-retardant electroplated ABS for electronic and electrical housings, which is made of the following components in parts by weight: 65-85 parts of ABS; 10-30 parts of flame retardant; 1-5 parts of filler; 0.1-0.5 parts of oxygen agent; 0.1-0.3 parts of lubricant. The invention also discloses a preparation method of the flame-retardant electroplating ABS (acrylonitrile-butadiene-styrene copolymer) used for the housing of the electronic appliance. The present invention can obtain a kind of flame retardant electroplating ABS used for electronic and electrical appliance shells through fillers and controlling the content of rubber phase in the system. The flame-retardant electroplating ABS used for the housing of electronic appliances meets the requirements of electroplating and electronic appliances on flame retardancy. The increase of filling substances is not only beneficial to the advantages of ABS material such as temperature resistance, flame retardancy and cost reduction, but also makes the flame retardant ABS material have electroplating and etching properties.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a flame-retardant electroplated ABS for electronic and electric appliance casings and a preparation method thereof. Background technique [0002] At present, electroplated acrylonitrile-butadiene-styrene copolymer (ABS) is widely used in the field of electronic and electrical housings, which has the advantages of aesthetics and anti-aging, but the traditional ABS used in electronic and electrical housings does not have flame retardant effect. There is a certain fire hazard during use. The international and domestic requirements for the flame retardancy of plastic materials used in electronic appliances are getting higher and higher. The UL standard of the United States has become an international standard and is being continuously improved. This has a certain impact on the flame retardancy of plastic products used in electronic appliances. Require...
