Abstract

The invention provides a material for an electric meter shell and a preparation method thereof, belonging to the field of electric materials. The material for the electric meter shell comprises the following raw materials by weight: polyvinyl chloride, polyethylene, methyl methacrylate, glass fiber, polycarbonate, polylactic acid, decabromodiphenylethane, polydimethylsiloxane, chitin, silicon nitride powder, silicon carbide powder, sodium succinate, talcum powder, barium sulfate, graphite powder, chromium carbide powder, boron nitride, alumina silicate, kaolin, polyamide resin, acetal resin, a flame retardant, a plasticizer, a coupling agent, a heat stabilizer, a light stabilizer and a lubricant. The preparation method comprises the following steps: (1) weighing of the above raw materials; and (2) centrifugation, melting, addition into a mold, shaping and cutting. The material and the preparation method thereof provided by the invention overcomes the problem that conventional materials for the electric meter shell need to be further improved and strengthened in mechanical strength, thermal stability and flame retardation.

Description

technical field [0001] The invention belongs to the field of power materials, and in particular relates to an electric meter shell material and a preparation method thereof. Background technique [0002] The housing of the meter is mainly used to protect the internal parts of the meter, which requires good mechanical properties, good thermal stability and flame retardancy. At present, flame-retardant ABS is mostly used as the housing material of electric meters in China. Although flame retardant ABS is cheap, its rigidity is not very good. Reinforced polycarbonate (PC) is mostly used abroad at present. With the development of my country's economy, a large number of reinforced PCs will be used as the housing material of electric meters in China. Polycarbonate is a colorless, transparent, amorphous thermoplastic material. Its chemical properties are resistance to weak acids, weak bases, neutral oils, ultraviolet light and strong bases. Its physical properties are linear expa...
