The auxiliary agent used in the embodiment can obviously improve the dispersibility and the leveling property of the coating system, and can obviously reduce the bubbles of the coating so as to ensure that the adhesive system fully wets the bonding base material, and the adhesive system with excellent bonding property can be obtained after curing.
Further, the adhesion promoter can reduce the interfacial tension between the matrix polymer and the adhered surface and increase the peeling strength and initial adhesion of the adhesive. The tackifier is any one of tackifying resin, cellulose ether and polyvinyl alcohol, and the tackifying resin has low molecular polarity, small molecular weight and high glass transition temperature, so that the interfacial tension between the adhesive and the ground is reduced, and the peeling strength and initial adhesion of the adhesive can be effectively enhanced; the cellulose ether can be combined with water to form a lubricating film, so that the wettability of the adhesive on the cement-based surface is further improved, the interface attachment is improved, and the bonding effect is improved; the polyvinyl alcohol with low polymerization degree has the polymerization degree of 2.5-3 ten thousand, has the characteristics of large polymerization degree and uniform dispersion after being dissolved in water, and according to the relation between the polymer and the viscosity, the higher the polymerization degree and the alcoholysis degree of the polymer, the stronger the bonding strength, the better the solvent resistance, and the higher the film strength after film forming, so that the viscosity of the aqueous solution of the polyvinyl alcohol after being dissolved in water is very high, and meanwhile, the polyvinyl alcohol can be uniformly dispersed after being dissolved in water, so that the polyvinyl alcohol is well dispersed in the system, and has no sedimentation and agglomeration phenomena, therefore, the strength and the solvent resistance after the polyvinyl alcohol film forming are excellent, so that the adhesive system also has excellent solvent resistance, and the volume shrinkage of the adhesive system after being cured can be reduced.
