Abstract

The invention relates to the technical field of adhesives, in particular to woodworking glue and a preparation method thereof.Polyvinyl alcohol 05 and polyvinyl alcohol 24 are combined for use, so that balance of fluidity and adhesive strength can be achieved in the glue, a thicker and waterproof film can be formed during combined use, the protection performance of a coating is improved, and the service life of the woodworking glue is prolonged. The adhesive strength, the water resistance and the mechanical strength of the glue are improved by adopting the acrylic monomer and the ethylene monomer, the succinic acid alkyl polyoxyethylene ether disodium sulfonate and the allyloxy hydroxypropyl sodium sulfonate are adopted as emulsifiers, the uniformity and the stability of the glue are guaranteed, and the adhesion of the glue to base materials such as metal and plastic is improved. The preparation method comprises the following steps: dissolving polyvinyl alcohol in water to obtain a polyvinyl alcohol aqueous solution, carrying out monomer copolymerization and aqueous solution emulsification to obtain a polyvinyl alcohol emulsion, and finally adding a performance auxiliary agent to obtain the woodworking glue with strong adhesion, tensile strength and excellent water resistance.
