Abstract

The invention discloses a preparation process for a wood adhesive with high adhesion strength. The preparation process comprises the following raw materials in parts by weight: 20-90 parts of vinyl acetate, 10-30 parts of a starch emulsion, 10-20 parts of an ammonium salt modified acrylate emulsion, 10-12 parts of dibutyl phthalate, 20-30 parts of nanosilicon dioxide sol, 10-60 parts of gulcomannan, 20-40 parts of chitosan and 10-15 parts of a soybean protein denaturant. The preparation method comprises the following steps: uniformly mixing the vinyl acetate, the starch emulsion, the dibutyl phthalate, the nanosilicon dioxide sol, the gulcomannan, the chitosan and the soybean protein denaturant, heating to 70-80 DEG C, stirring to carry out a reaction for 2-3 hours, cooling to the room temperature, adding the ammonium salt modified acrylate emulsion, heating to 100-120 DEG C to carry out a reaction for 20-30 minutes, and cooling. The wood adhesive disclosed by the invention has the advantages of being high in adhesion strength and good in water resistance.

Description

technical field [0001] The invention relates to a preparation process of a wood adhesive with high bonding strength. Background technique [0002] The most prominent feature of wood adhesives is that they are used in large quantities. The cost, variety, and quality of adhesives directly affect the cost, quality, and use of wood-based panels. Therefore, most wood processing enterprises in my country have their own glue-making workshops. The main types of glue produced are urea-formaldehyde resin glue, phenolic resin glue and Melamine resin glue. At the same time, with the increase in the variety of wood glued products and the continuous improvement of their quality requirements, specialized glue-making enterprises have emerged. Adhesive industry is one of the fast-growing fine chemical industries in China since the implementation of the reform and opening up policy. Adhesives are easy to use and have good economic benefits, providing an effective way for various industries ...
