Abstract

The invention relates to the industrial field of wood product coating treatment, discloses a modified polyacrylate coating for wooden products, which uses polymerization reaction of 1,3-cyclobutanediol,2,2,4,4-tetramethyl and bisphenol-A dimethylcyclohexane to acrylic ester for control and modification. The modified polyacrylate coating prepared by graft polymerization has excellent comprehensivecharacteristics, including significantly-improved abrasion performance, good solvent resistance, improved light and weather resistance, strong adhesive, good film-forming property, no need of adding film coalescing agents, film-forming temperature up to -5 DEG C, and widely applicable to processing of various wooden products. The invention provides an effective way to improve the abrasion performance, the solvent resistance and other performance of polyacrylate coating for wooden products, which has the advantages of simple process operation, high efficiency, easy operation, safety and reliability, long service life, and is a technical scheme worthy of popularization.
