Problems solved by technology

In recent years, many chemical companies have produced new water-based acrylic adhesives, but the application of water-based acrylic adhesives is still very limited. Water-based acrylic uses water as the dispersion medium, and the latent heat of volatilization of water is higher than that of solvents. The prolongation of the drying time of the acrylic film causes the adhesive to have disadvantages such as high activation temperature, high price, low solid content, low water resistance and temperature resistance of the film, and unsatisfactory initial and final bonding strength, especially for bonding. Low strength seriously affects its application

Abstract

The invention belongs to the field of a chemical industry, and especially relates to an aqueous acrylic acid adhesive and a preparation method thereof. The aqueous acrylic acid adhesive comprises thefollowing components in parts by weight: 15-20 parts of acrylic acid, 10-15 parts of methyl acrylate, 10-15 parts of ethyl acrylate, 10-15 parts of acrylic acid-2-ethylhexyl acrylate, 10-15 parts of methyl methacrylate, 10-15 parts of butyl acrylate, 5-10 parts of dimethylolpropionic acid, 5-10 parts of an emulsifier, 5-8 parts of triethylamine, 3-5 parts of a silane coupling agent, 3-5 parts of ablocking agent, 3-5 parts of an adhesion agent, 3-5 parts of aqueous silicone oil, and 300-500 parts of deionized water. The technology is simple and easy to control, and a polymerization system is stable; the obtained adhesive has the advantages of good mechanical stability, storage stability, and compatibility with a general auxiliary agent, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a water-based acrylic adhesive and a preparation method thereof. Background technique [0002] Adhesives are essential materials for the development of modern industry and the improvement of human living standards. Adhesives play an important role in modern economy, modern national defense, and modern science and technology. Because of its simple process, cheap raw materials, high bonding strength, colorless and transparent, etc., it is widely used in the bonding of wood-based panels and interior decoration and other industries. At present, most of the adhesives on the market are made by traditional methods, which have poor alkali resistance, solvent resistance and abrasion resistance, and the use effect is not ideal, and the adhesive contains too many organic chemical components. The hazards are serious. Acrylic emulsion is widely used in the field of adhesives due to its exce...
