Abstract

The invention provides an adhesive for connecting wood, particularly relates to a high-temperature-resistant wood adhesive and a preparation method thereof, and belongs to the technical field of adhesives. The high-temperature-resistant wood adhesive comprises the following components: plant starch, pentalyn, glycerol ester of hydrogenated rosin, barium sulfate, amine p-tolyl sulfinate, ammonium chloride, magnesium oxide, potassium peroxodisulfate, polyvinyl alcohol, butyl latex, resorcinol, microcrystalline wax, butyl methacrylate, triammonium citrate, calcium carbonate, phenol, 2-benzyl-4-chlorophenol, a formaldehyde aqueous solution, carbamide, melamine, sodium hydroxide, a surfactant, sodium hexadecyl benzene sulfonate and water. The bonding strength of the high-temperature-resistant wood adhesive can be higher than 2 MPa, and still be higher than 1.90 MPa after the high-temperature-resistant wood adhesive is soaked in water.

Description

[0001] technical field [0002] The invention provides an adhesive used for wood connection, in particular relates to a wood adhesive with high temperature resistance and a preparation method thereof, belonging to the technical field of adhesives. [0003] Background technique [0004] Adhesives are modern fine chemicals. Since the 21st century, adhesives and bonding technology have shown incomparable vigor and vitality, and their importance is increasing day by day. , creating considerable economic and social benefits. In European and American countries, the growth rate of adhesives is higher than that of the gross national product, with an average growth rate of about 3%. The world's annual sales volume of adhesives has now exceeded 10 million tons, and the global sales of synthetic adhesives have exceeded 26 billion US dollars. [0005] Wood is composed of various cells: tracheids, wood fibers are the main part of the cells and have a decisive influence on the propert...
