Abstract

The invention belongs to the field of materials, and relates to a fireproof material of a housing of a storage battery. The housing comprises a metal layer, a polypropylene plastic layer and a ceramicsilicone rubber layer which are sequentially arranged from inside to outside, wherein the ceramic silicone rubber layer is prepared from the following raw materials in parts by weight: 100 parts of silicone rubber, 20-60 parts of ceramic preparing filler, 5-15 parts of a fluxing agent, 0.2-1.5 parts of a platinum catalyst, 2-8 parts of hydroxyl silicone oil, and 2-4 parts of a vulcanizing agent;and the ceramic preparing filler is a mixture of alumina silicate fibers and needle aedelforsite based on the mass ratio of (15-25): (30-40). A plurality of materials are matched with one another to jointly construct the material of the housing of the storage battery; the outermost ceramic silicone rubber layer ensures high fireproofing performance of the storage battery; in case of fire at the outside, the ceramic silicone rubber can be converted into a ceramic body with a dense structure for preventing outside fire from invading to cause combustion of inside materials, and moreover, the riskthat battery fluid leaks from a damaged vessel to cause explosion can be avoided.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a storage battery casing material, in particular to a storage battery casing material with fireproof performance. Background technique [0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is a battery designed to be rechargeable. It is recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery. , belonging to the secondary battery. Its working principle: when charging, the external electric energy is used to regenerate the internal active material, the electric energy is stored as chemical energy, and the chemical energy is converted into electric energy output again when it needs to be discharged. The shell of the storage battery is mainly made of plastic material, usually polypropylene, ABS and other plastics. In order to meet the requirements of fire and flame retardancy, fla...
