The important position of epoxy glue in solid wood furniture

Gluing is the use of adhesive to firmly join the objects together. Gluing technology is widely used in modern industrial and agricultural production. Epoxy adhesive is a high-performance adhesive that cannot be separated from the production of solid wood furniture. It is produced in solid wood furniture. It occupies an important position.

There are many types of adhesives, different in nature, wood is a polar substance, and the adhesive is also a polar substance in order to make the wood and the adhesive firmly glued. The adhesive used in the wood industry accounts for about 60% of the total adhesive production. Among the adhesives used in the production of solid wood furniture, although the epoxy emulsion is not the largest, it is the best and most environmentally friendly.

The process of firmly joining two glued joints together with adhesive is called glue bonding. The processes of joint, finger joint, thin wood mold sticking, jigsaw and so on involved in the manufacturing process of solid wood furniture are inseparable from the glue technology. . During the bonding process of solid wood furniture parts, a series of physical and chemical changes have taken place on the surface of the wood, and a series of bonding theory has been formed through long-term research. Such as mechanical bonding mechanism, adsorption bonding mechanism, diffusion bonding mechanism, chemical bonding mechanism, chemical reaction between adhesive and adherent molecules to obtain high-strength primary valence bond, chemical bond force is greater than intermolecular force many.

In the process of bonding the solid wood furniture, the chemical bond between the adhesive and the adherend molecules, between the surface treatment and the obtained active group and the adhesive is mainly formed by the adhesive and the active group and the coupling agent in the glue. .The above several mechanisms can only reflect one side of the gluing phenomenon. In fact, the gluing of wood is the result of several forces acting together. Epoxy resin adhesive is one of the most effective adhesives because of its excellent performance. It has formed an important position in the production of solid wood furniture.
