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 metallocene polyethylene wood adhesive. The wood adhesive comprises, by weight, 7-10 parts of hydrogenated rosin glycerin ester, 72-80 parts of metallocene polyethylene, 6-10 parts of poly(n-butyl methacrylate), 1-2 parts of 2-mercaptobenzoimidazole, 2-3 parts of polymaleic anhydride, 1-2 parts of magnesium silicate, 0.7-1 part of hexafluoroacetylacetone, 2-3 parts of calcium aluminate, 0.6-2 parts of 1-hydroxycyclohexylphenylketone, 0.4-1 part of methacrylic acid, 1-2 parts of casein, 0.4-1 part of sodium abietate 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 obtained finished product is improved, and the toughness of the finished product is also improved.
