Abstract

A disclosed sealant for electric vehicles is prepared from the following raw materials in parts by weight: 15-20 parts of cis-1,4-polybutadiene rubber, 6-9 parts of carbon black, 6-10 parts of sodium silicate, 10-18 parts of polyisobutylene, 5-8 parts of zinc oxide, 6-9 parts of ebonite, 4-7 parts of a lubricant, 10-15 parts of nanometer calcium carbonate, 9-18 parts of dioctyl phthalate, 3-7 parts of barium sulfate, 15-20 parts of thermoplastic synthetic resin, 4-8 parts of calcium carbonate, 11-18 parts of rutile titanium dioxide, 4-8 parts of a phosphate flame retardant and 5-10 parts of diatomite. The provided sealant for electric vehicles is good in stability, good in gumminess, not easy to crack in sun and fall off, and good in fireproof effect.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an electric vehicle sealant. Background technique [0002] Sealants are mainly used for bonding various objects or filling gaps, and their functions are mainly reflected in the two aspects of bonding and sealing. Due to the rapid development of various industries, the application fields of sealants are constantly expanding. In some occasions, sealants are required not only to have the functions of bonding and sealing, but also to have functions such as fire prevention and flame retardancy. In the prior art, there are very few sealants used on electric vehicles, and the sealant for electric vehicles currently on the market has poor stability, poor adhesion, and is easy to dry and fall off in high temperature environments, which seriously affects the adhesion of automotive seals . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical pro...
