Power distribution box case material and preparation method thereof

Abstract

The invention discloses a power distribution box case material and a preparation method thereof, and relates to the field of a power distribution box material. The power distribution box case materialis prepared from the following raw materials in parts by weight: 35 to 50 parts of polycarbonate, 20 to 28 parts of polyphenyl ether resin, 6 to 12 parts of ethylene zinc ene copolymers, 3 to 8 partsof dioctyl phthalate, 14 to 20 parts of acrylic resin, 12 to 18 parts of kaolin, 5 to 13 parts of dolomite, 4 to 10 parts of aluminum triphosphate, 7 to 15 parts of silicon carbide, 6 to 12 parts ofmodified carbon nanometer tubes, 5 to 10 parts of nanometer titanium dioxide, 5 to 10 parts of nanometer zinc oxide, 2 to 4 parts of white carbon black, 1 to 4 parts of polyethylene wax, 0.6 to 1.5 parts of silane coupling agents and 1.2 to 1.8 parts of antioxidants. Through the cooperated effects between the raw materials, the power distribution box case material has the advantages of anti-corrosion performance, good weather resistance performance and temperature resistant performance, pressure resistance, mechanical impact resistance, anti-scratching performance and excellent heat conductionperformance.

Description

technical field [0001] The invention relates to the field of distribution box materials, in particular to a distribution box shell material and a preparation method thereof. Background technique [0002] The distribution box is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then the low-voltage side of the transformer is stepped down to lead to low-voltage The distribution box and the low-voltage distribution box are connected to each power distribution panel, control box, and switch box. Inside, some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices are assembled into one The equipment of the power distribution device that meets the design function requirements. The high and low voltage distribution box is also called: high and low voltage switchgear or high ...

Problems solved by technology

[0003] Chinese patent CN104151758B discloses a distribution box shell material, which is prepared from the following raw materials: kaolin, glass fiber, tetraethyl orthosilicate, butyl acetate, aluminum tripolyphosphate, antimony trioxide, diethylene glycol Monobutyl ether, isobutanol, polycarbonate, glyceryl monostearate, quartz sand, phenolic resin, borax, silicon carbide and acrylic resin, the distribution box shell material of the present invention has good mechanical properties, flame retardant performance and It is greatly improved, but the flame retardancy of the distribution box shell material of the present invention is insufficient, which will easily cause the internal temperature of the distribution box to be too high, which will affect the operation of the internal components

It is suitable for use as a manufacturing method for distribution boxes, but the preparation process of the present invention is complicated and difficult to operate, so the scope of popularization and application is small
