Special heat-resistant, high-impact and flame-retardant resin for outer casing of storage battery

Abstract

The invention discloses special heat-resistant, high-impact and flame-retardant resin for an outer casing of a storage battery. The special heat-resistant, high-impact and flame-retardant resin is prepared from the following raw materials and components in parts by mass: 30 to 50 parts of ABS (acrylonitrile butadiene styrene) powder, 40 to 60 parts of styrene-acrylonitrile resin, 10 to 30 parts ofbutadiene, 20 to 35 parts of heat-resistant agent, 10 to 18 parts of bromine flame retardant, 3 to 8 parts of antinomy flame retardant, 0.5 to 2 parts of antioxidant, and 0.1 to 1 part of anti-dripping agent. The special heat-resistant, high-impact and flame-retardant resin has the beneficial effects that the ABS with high-impact property is used as the main raw material, and is added with the bromine flame retardant, the antinomy flame retardant and the anti-dripping agent, so that the flame-retardant property is obviously improved; by adding the heat-resistant property, the heat-resistant temperature of the ABS material is obviously increased; by adding the antioxidant, the corrosion-resistant property of the outer casing of the storage battery is improved; the heat-resistant property,corrosion-resistant property, high-impact property and obvious fireproof property are realized; the ABS material has good shrinkage property, so that the expanded and deformed outer casing can be restored in the charging process.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a special heat-resistant, high-impact and flame-retardant resin for storage battery casings. Background technique [0002] A battery is a device that converts chemical energy into electrical energy. After discharge, the internal active material can be regenerated by charging - the electrical energy is stored as chemical energy, and the chemical energy is converted into electrical energy again when it needs to be discharged. This type of battery belongs to the secondary battery. The battery casing contains electrolyte and polar plates, and the battery will continue to generate heat during charging and discharging, so the battery casing needs to have high heat resistance and flame retardancy. [0003] The existing batteries are mainly made of hard rubber, which is hard and brittle, and does not have heat resistance, corrosion resistance, high impact resistance and signif...

Problems solved by technology

[0003] The existing batteries are mainly made of hard rubber, which is hard and brittle, and does not have heat resistance, corrosion resistance, high impact resistance and significant fire resistance. When the battery is charged, gas will be generated inside, resulting in The product will expand and easily deform the battery case by impact
