Problems solved by technology

[0002] At present, there are many types of wood adhesives. Wood-based panel factories mainly use adhesives such as urea-formaldehyde resin and phenolic resin to produce fiberboard, plywood, particleboard and other boards. Some of them are based on the original polyvinyl acetate emulsion, acrylic emulsion, and polyurethane adhesive. Soybean-based wood adhesives, starch-based wood adhesives, other crop-based wood adhesives, and modified isocyanate adhesives have been developed. Although they all have certain adhesive properties, they still have many shortcomings, such as poor weather resistance and boiling water resistance. Poor resistance, poor frost resistance, acid resistance, etc., can make the colloid deteriorate, thus losing the bonding effect

Abstract

The invention discloses a low-viscosity wood adhesive. The low-viscosity wood adhesive comprises, by weight, 0.5-1 part of powdery butyronityile, 0.7-2 parts of lauryl methacrylate, 2-3 parts of polyvinyl butyral ester, 1-2 parts of sodium myrastate, 2-3 parts of cyclodextrin, 0.4-1 part of lead sulfate tribasic, 0.8-1 part of copper 8-hydroxyquinoline, 1-2 parts of 2,6-ditertbutyl-4 methylphenol, 65-80 parts of ethylene-ethyl acrylate copolymer, 6-8 parts of nanometer powdery carbon, 7-9 parts of hydrogenated rosin resin and 4-7 parts of a bio-adhesive. The bio-adhesive adopts elm bark powder as a structural reinforcing agent, and cooperates with high-viscosity polyacrylamide to make formed gel have the characteristics of fibers and have certain toughness, so the viscosity of the above finished product is improved, and the toughness of the finished product is improved.

Description

technical field [0001] The invention mainly relates to the glue field, in particular to a low-viscosity wood glue. Background technique [0002] At present, there are many types of wood adhesives. Wood-based panel factories mainly use adhesives such as urea-formaldehyde resin and phenolic resin to produce fiberboard, plywood, particleboard and other boards. Some of them are based on the original polyvinyl acetate emulsion, acrylic emulsion, and polyurethane adhesive. Soybean-based wood adhesives, starch-based wood adhesives, other crop-based wood adhesives, and modified isocyanate adhesives have been developed. Although they all have certain adhesive properties, they still have many shortcomings. Some have poor weather resistance and boiling water resistance. Poor resistance, poor frost resistance, acid resistance, etc., can cause the colloid to deteriorate and lose its bonding effect. Contents of the invention [0003] The purpose of the present invention is to p...
