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 bio-adhesive timber glue. The bio-adhesive timber glue comprises, by weight, 0.2-0.4 parts of sarcosyl, 0.1-0.3 parts of polydimethylsiloxane, 0.1-0.2 parts of tri-n-butyltin chloride, 2-3 parts of bone black, 2-4 parts of distearyl thiodipropionate, 3-5 parts of trumpet shell powder, 0.4-1 part of linoleic acid, 3-4 parts of dibutyl maleate, 5-7 parts of perchloroethylene resin, 80-86 parts of chlorosulfonated polyethylene, 0.6-1 part of tert-butyl peroxyformate, 0.3-1 part of turpentine and 5-6 parts of a bio-adhesive. The bio-adhesive utilizes elm bark powder as a structure reinforcing agent and also utilizes high viscosity polyacrylamide so that the gel has fiber characteristics and a certain toughness and thus finished product viscosity is improved and finished product toughness is improved.
