Problems solved by technology

However, a large amount of halogen flame retardants added to flame retardant sealants will generate a large amount of toxic gases such as hydrogen halide during the combustion process, while halogen-free flame retardant materials, such as magnesium hydroxide and aluminum hydroxide, have poor flame retardant effects and are added in large amounts. , seriously affect the material properties
At the same time, due to the addition of a large amount of flame retardant, the fluidity of the sealant is reduced, and it is not easy to soak into the narrow caulking, which brings inconvenience to the construction

Abstract

The invention discloses an ethyl ester and furfuryl carboxylate based flame-retardant storage battery sealant and a preparation method. The sealant contains a component A and a component B. The component A is prepared from 2-aminoethyl methacrylate, a solvent, dinonyl phthalate, antimony trioxide, a reinforcing filler, an antioxidant and chlorosulfonated polyethylene. The component B is prepared from tetrahydrofurfuryl methacrylate, acrylate rubber, benzyl dimethylamine, a phosphonate flame-retardant plasticizer, gas-phase silicon dioxide, a solvent, BYK-066N and r-amino propyl triethoxysilane. The adhesive containing two different components is prepared by conducting vacuum kneading on adhesives of the two components A and B and mixing in a reaction kettle. The raw materials in the components A and B are reasonably prepared to make the two components well bonded in the using process, internally produced air bubbles are decreased, adhesive gaps are decreased, meanwhile good fireproof and heat-insulation properties are added, the original liquidity of the adhesive is guaranteed, and the discharge of harmful substances is decreased.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a flame retardant battery sealant based on ethyl ester and furfuryl alcohol ester and a preparation method thereof, which has a sealing effect on a battery. Background technique [0002] Polymer materials are widely used in the building materials industry. However, the polymer materials themselves are very easy to burn. When a fire occurs, the combustion releases a large amount of toxic gases, such as carbon monoxide and nitric oxide, which can poison people in a very short time. die. A large number of data show that poisonous smoke is the number one killer of people dying in fires. Therefore, the flame retardant properties of building materials are directly related to the safety of people's lives and property. However, the halogen flame retardants added in a large amount of flame retardant sealants will generate a large amount of toxic gases such as hydrogen halide d...
