High-gloss anti-crack adhesive for multilayer plywood and method for manufacturing multilayer plywood

A high-gloss anti-crack adhesive for multilayer plywood is provided. The multilayer plywood is mutually glued and laminated by a single layer material. The adhesive includes a urea-formaldehyde resin adhesive and additive and added additives therein, a melamine resin adhesive and added additives therein. The preparation methods of the urea-formaldehyde resin adhesive and the melamine resin adhesive are creatively improved by inventors. The free formaldehyde in the obtained adhesive is less than 0.1%. Operation is easy, equipment is easy to get, no pollution generates, implementation is easy and price is inexpensive. The high-gloss anti-crack adhesive can be used for the multi-layer plywood, has excellent pre-pressing property, can mold at room temperature in 30-40 min, and has bonding strength >= 1.0 MPa, formaldehyde emission = 85 DEG. In the environment with sudden changes in temperature, the high-gloss anti-crack adhesive has the advantages of preventing wear-resistant material cracking and bubbling as a result of thermal expansion and cool contraction.
