High-performance aqueous polyurea adhesive

Abstract

The invention discloses a high-performance aqueous polyurea adhesive. The high-performance aqueous polyurea adhesive is prepared from the following raw materials in parts by weight: 15-25 parts of polyethylene glycol, 10-20 parts of N-N-dimethylformamide, 5-10 parts of sulfoxide chloride, 6-11 parts of o-aminophenol, 3-6 parts of tetrabutylammonium bromide, 3-8 parts of dichloromethane, 10-15 parts of anhydrous potassium carbonate, 30-45 parts of epoxy resin, 4-10 parts of hexamethylene diisocyanate, 3-6 parts of aqueous polyacrylate, 4-7 parts of polyorganosiloxane, 5-10 parts of an additive and the balance of deionized water. According to the high-performance aqueous polyurea adhesive, the glue agglomeration time is effectively prolonged, the infiltration to a substrate is improved, and meanwhile, the mechanical property of polyurea glue is greatly improved.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a high-performance water-based polyurea adhesive. Background technique [0002] Polyurea adhesive has attracted more and more attention due to its excellent characteristics and convenient construction performance, but due to its rapid response, it has poor wettability to the substrate, resulting in poor adhesion to the substrate, which is easy to cause the substrate The adhesive strength of the material is not strong, and a good bonding effect cannot be initiated, so the application field of the polyurea adhesive is greatly limited. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-performance water-based polyurea adhesive, which effectively prolongs the polyurea time, improves the wettability of the substrate, and at the same time greatly improves the mechanical properties of the polyurea adhesive. [0004] In order t...
