Abstract

The invention discloses flame-retardant plastic for an electronic product casing. The plastic is prepared from the following raw materials in parts by weight: 60-80 parts of polycarbonate, 30-40 parts of acrylonitrile-butadiene-styrene (ABS) plastic, 3-9 parts of an antioxidant 1010, 1-4 parts of master batch, 5-10 parts of silane coupling agent, 12-18 parts of polyvinyl chloride resin, 11-16 parts of a lubricant and 0.9-1.2 parts of a fire retardant, wherein the lubricant is a mixture of calcium stearate, glyceryl tristearate and ethylene bisstearamide; and the fire retardant is a mixture of antimonous oxide, polyphenylene sulfide, ammonium polyphosphate and alkyl benzene sulfonate. By using the mixture of the antimonous oxide, polyphenylene sulfide, ammonium polyphosphate and alkyl benzene sulfonate as the fire retardant, the flame-retardant plastic for the electronic product casing disclosed by the invention is good in flame-retardant effect, free from halogen element and low in fuming amount; by adding the antioxidant, the aging resistance of the plastic is improved, and by virtue of the plastic, the tensile property of the plastic is enhanced.

Description

technical field [0001] The invention relates to a flame-retardant plastic for electronic product shells, belonging to the technical field of engineering plastics. Background technique [0002] With the continuous development of science and technology and economy, daily necessities made of plastics play an increasingly important role in daily life. However, plastics are flammable and burn quickly, producing a large amount of toxic gases. At present, there have been many reports of mobile phone shells being burned and scalding users. Therefore, it is very important to choose to add flame retardants to plastic formulations. [0003] Requirements for flame retardants: (1) It must have good flame retardant function, and the flame retardant effect can be obviously achieved with a small amount; (2) The mechanical strength of the plastic cannot be affected after the flame retardant is added, especially the plastic cannot be reduced. The heat distortion temperature, mechanical temp...
