Abstract

The invention discloses a polysulfide sealant and a preparation method thereof. The polysulfide sealant comprises polyether triol, thio alcohol, isocyanate, liquid polysulfide rubber, graphene oxide, epoxypropane butyl ether, acrylate emulsion, phenolic resin, dibutyl ester, filling materials, a tackifier, and a plasticizer. The preparation method comprises the following steps: performing coarse mixing of polyether triol, thio alcohol, isocyanate, liquid polysulfide rubber, graphene oxide, epoxypropane butyl ether, acrylate emulsion, phenolic resin, and dibutyl ester in a kneader, transferring the mixture into a reaction device, stirring at 30-50 DEG C, then adding the filling materials, the tackifier, and the plasticizer, performing vacuum-pumping, heating to 50-60 DEG C, keeping vacuum, performing heat preservation and stirring for 1-2 hours, cooling with a cooling device, filtering by a filter device, filling with an automatic filling device, and storing the product. The purpose of the invention is to provide the polysulfide sealant with reasonable components and ratios, and good adhesive property, and the preparation method.

Description

technical field [0001] The invention relates to a polysulfide sealant; the invention also relates to a method for preparing the polysulfide sealant. Background technique [0002] Adhesive refers to a kind of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through the adhesion and cohesion of the interface, collectively referred to as glue. Adhesives, also known as adhesives, are customarily referred to as glue. In short, an adhesive is a substance that can bind adherends together through bonding; traditional adhesives have poor adhesion due to unreasonable formula ratios and cannot meet the needs of use. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a polysulfide sealant with reasonable components and ratio and good bonding performance. [0004] Another object of the present invention is to provide a method for preparing th...
