Problems solved by technology

[0002] Polysulfide sealant is used in a wide range and is a very good sealing material. It has the advantages of very reliable sealing effect and convenient use, but because the raw material is flammable, it causes certain safety hazards. Although the addition of inorganic flame retardants can have improved, but there are often compatibility problems and reduce the strength of the sealant

Abstract

The invention discloses an environment-friendly high-strength high-flame-retardant polysulfide sealant. The environment-friendly high-strength high-flame-retardant polysulfide sealant comprises an A sealant ingredient and a B sealant ingredient; the A sealant ingredient comprises liquid polysulfide rubber, butyl benzyl phthalate, calcium carbonate, sulphur, a coupling agent, amino-terminated sulfonated polybenzimidazole prepolymer, and an epoxy quaternary ammonium salt; and the B sealant ingredient comprises manganese dioxide, a vulcanization accelerator, carbon black, and 2,2'-bis(4-carboxyl phenoxy) benzidine. The invention also discloses a preparation method of the environment-friendly high-strength high-flame-retardant polysulfide sealant.

Description

technical field [0001] The invention belongs to the technical field of polymer sealing materials, and more specifically relates to an environment-friendly high-strength and high-flame-retardant polysulfide sealant and a preparation method thereof. Background technique [0002] Polysulfide sealant is used in a wide range and is a very good sealing material. It has the advantages of very reliable sealing effect and convenient use, but because the raw material is flammable, it causes certain safety hazards. Although the addition of inorganic flame retardants can have It has been improved, but there are often compatibility problems and the strength of the sealant is reduced. In addition, since sealants are often used in household life, such as kitchens, it is also expected that they have certain antibacterial properties and are safer and more environmentally friendly. [0003] Therefore, it is very necessary to improve the formulation and production process without adding inorg...
