A versatile cold-curing wood adhesive derived from butylphenyl polyester

Although there have been notable advances in wood-based adhesive materials, the ability to rapidly bond wood under cold curing conditions at room temperature remains a challenge in these adhesives. Here, we report a new butylphenyl-derived polymer that can achieve super strong adhesion at room temperature by fast response at the wood interface. This behavior is achieved by the external reactive groups to create strong interfacial forces and the internal construction of organic-inorganic hybrid structures to reduce energy dissipation. Our research has established an effective method to modulate the viscoelasticity of the copolymer and optimize the adhesion properties of the adhesive at room temperature. The adhesive has a lap shear strength of 4.2 +/- 0.17 MPa and also has a repair function that allows the repaired wood to withstand tensile forces of up to 470 N. It is anticipated that this dry, self-supporting, low-cost functional latex will be used as a commercial product for furniture restoration, wood industry and other applications.
