Problems solved by technology

However, ABS resin is a flammable material. The existing technology uses ABS resin for battery slots, which cannot meet the requirements of batteries.
The shortcomings of short service life of the battery and easy pollution of the environment during use
Chinese patent CN200810059699.3 discloses the use of decabromodiphenyl ether and antimony-based flame retardants to prepare flame-retardant ABS resin for valve-regulated battery shells, but this material does not meet environmental protection requirements and cannot be used as battery tank materials
Chinese patent CN200510110092.X discloses a preparation method of heat-resistant and flame-retardant ABS resin. The invention uses a heat-resistant modifier to increase the heat distortion temperature. The heat-resistant modifier is an alkaline compound, so that the material cannot be used in an acid battery tank use
[0004] The heat-resistant and flame-retardant ABS materials used in the prior art for battery tanks have not been reported in the literature

Abstract

The invention belongs to battery jar materials, and discloses a flame-retardant and heat-resistant material for a battery jar and a preparation method thereof. An acrylonitrile butadiene styrene (ABS) resin battery jar of the prior art cannot meet flame-retardant and heat-resistant requirements of a battery. The flame-retardant and heat-resistant material consists of the following materials in part by weight: 20 to 35 parts of ABS high glue powder, 35 to 60 parts of styrene-acrylonitrile resin, 5 to 20 parts of brominated epoxy flame retardant, 3 to 6 parts of antimony flame retardant, 2 to 6 parts of powdered butadiene-acrylonitrile rubber, 0.2 to 1 part of antioxidant, and 0.2 to 1 part of processing agent. The preparation method comprises the following steps of: adding the raw materials into a high-speed mixer for uniform mixing; delivering the mixture into a twin-screw extruder of which the length-diameter ratio is 32 to 40; and performing mixing, extruding, strip pulling, cooling, and chopping to obtain the flame-retardant and heat-resistant material. The flame-retardant and heat-resistant material has the advantages of high flame retardance and heat resistance to prolong the service life of the battery, high impact resistance and chemical corrosion resistance to meet working requirements of the battery, and simple preparation process which is easy to operate.

Description

technical field [0001] The invention relates to a battery tank material, in particular to a flame-retardant and heat-resistant material for a battery tank and a preparation method thereof. Background technique [0002] Storage battery has been widely used since its invention due to its ease of use. The battery itself is a sealed chemical reactor, which generates heat and internal pressure during charging and discharging, which puts forward high requirements on the heat resistance, impact resistance, rigidity, corrosion resistance and flame retardancy of the battery tank material . [0003] ABS resin has the advantages of excellent heat resistance, impact resistance, rigidity, corrosion resistance and dimensional stability, and is widely used in many fields such as household appliances, electronic and electrical products, industrial spare parts, and automobile industry. However, ABS resin is a flammable material, and the existing technology uses ABS resin for battery slots,...
