Abstract

The invention discloses a water-based adhesive and a preparation method thereof. The preparation method of the water-based adhesive comprises the following steps: (1) weighing 20-40 parts of ethylene-vinyl acetate emulsion, 50-70 parts of acrylate emulsions, 10-40 parts of a water-based viscous emulsion and 0.2-0.6 part of an antifoaming agent, dispersing the weighed raw materials evenly in a high-speed disperser to obtain a base emulsion; (2) adding 0.3-0.8 part of a coalescing agent and 0.2-0.6 part of a mildew preventive to the base emulsion, stirring evenly to obtain the first water-based adhesive. In such manner, the water-based adhesive which is fast cured, high in initial adhesion and excellent in permanent adhesion can be provided.

Description

Technical field [0001] The invention relates to an aqueous adhesive and a preparation method thereof. Background technique [0002] Adhesive is a substance that firmly bonds various solid materials together by interface. Adhesives are mainly composed of bonding substances, curing agents, toughening agents, diluents, fillers and modifiers. They are widely used in the automotive industry, shipbuilding industry, aerospace industry, electronic and electrical industry, construction industry, medical industry, light Textile industry and packaging industry. [0003] Water-based adhesives are solvent-free, safe, and environmentally friendly, and have gradually replaced solvent-based adhesives. However, the existing water-based adhesives have problems such as insufficient initial tack and slow curing speed, which cannot well meet the use requirements. Summary of the invention [0004] The main technical problem to be solved by the present invention is to provide a water-based adhesive and...
