Abstract

The invention discloses a flame-retardant electroplating ABS for the shell of an electronic apparatus. The flame-retardant electroplating ABS is prepared by using the following components, by weight, 65-85 parts of ABS, 10-30 parts of a flame retardant, 1-5 parts of a filler, 0.1-0.5 parts of an antioxidant and 0.1-0.3 parts of a lubricant. The invention also discloses a preparation method of the flame-retardant electroplating ABS (acrylonitrile butadiene styrene copolymer) for the shell of the electronic apparatus. The flame-retardant electroplating ABS for the shell of the electronic apparatus can be obtained by controlling the content of the filler and a rubber phase in a system. The flame-retardant electroplating ABS for shell of the electronic apparatus meets the flame retardation requirements of electroplating and electronic products. The increase of the filler benefits the heat resistance and the flame retardation of the ABS material, reduces the cost, and makes the flame retardant ABS material have an electroplating etching property.

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. Requir...
