Abstract

The invention discloses an adhesive for engineered wood floors. The adhesive is prepared by mixing the following components in parts by weight: 1-5 parts of an emulsifier, 20-30 parts of corn flour, 20-30 parts of chitosan, 10-20 parts of soybean protein, 15-25 parts of bagasse lignin, 1-5 parts of a toughening agent and 5-10 parts of nano-montmorillonite. By adopting the process, the adhesive is good in adhesive property and filming property, environment-friendly, free of harmful gas emission, good in water resistance and high in adhesive strength.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive for solid wood composite flooring. Background technique [0002] Inheriting the characteristics of solid wood flooring that are elegant and natural, comfortable to the feet, and good thermal insulation performance, it overcomes the shortcomings of solid wood flooring that are prone to warping and cracks due to monomer shrinkage, has good dimensional stability, and is insect-proof, non-combustible, and non-warping out of shape. From the perspective of protecting forest resources, it is the replacement product of solid wood flooring. It has the advantages of convenient installation and maintenance of reinforced composite flooring, and avoids the disadvantages of high formaldehyde emission and stiff foot feeling of reinforced composite flooring. The high-grade solid wood composite floor adopts high-grade matt paint, which has high wear resistance and soft luminosity. Generall...
