Problems solved by technology

This kind of panel glue has high bonding strength, good water resistance, no organic solvents, and no formaldehyde. 2~4 hours), the jigsaw glue will solidify and fail, causing loss
In addition, this panel glue also has the following disadvantages: First, the modified polyisocyanate is used as the crosslinking agent, and its residual toxicity is harmful to the environment and human body
Secondly, this panel glue is copolymerized with butyl acrylate and vinyl acetate, which has a low degree of improvement in water resistance.
Thirdly, the use of common non-ionic emulsifier OP-10 is prone to migration of the bonding interface and reduced bond strength
Finally, ordinary polyvinyl alcohol is used, which has low water resistance

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a one-component puzzle glue and a preparation method thereof. Background technique [0002] Panel glue refers to the adhesive used for splicing glulam and other wood products, and is suitable for panel bonding of non-structural materials and glulam for structural materials. Adhesives commonly used in various wood products, furniture and decoration industries in my country mainly include urea-formaldehyde, phenolic resin, melamine-formaldehyde glue (ie trialdehyde glue), polyvinyl acetate emulsion (white glue). [0003] The main formula raw materials of urea-formaldehyde, phenolic resin, and melamine-formaldehyde glue (namely trialdehyde glue) products are: urea, formaldehyde, melamine, catalyst and water. During the reaction of the above raw materials to synthesize trialdehyde glue, the amount of formaldehyde released is high, which seriously pollutes the air environment and i...
