Abstract

The invention provides UV light-cured resin for an elastic wood veneer. According to the UV light-cured resin, polyester diol is taken as a main component, aliphatic isocyanate and polyester diol are introduced to have a synergistic effect, and the diol component is matched with isocyanate with different degrees of functionality, so that the resin with a cross-linked network structure can be obtained; the reaction activity and the mechanical property of the resin are effectively improved; a synergistic effect of an end-capping monomer is also provided; the end-capping monomer can act on the polyester system, so that the reaction activity of the material is effectively ensured, the supporting property and the weather resistance of the resin are improved; and meanwhile, a UV monomer, a catalyst and a polymerization inhibitor are added, so that the interaction of all the components is facilitated, and it can be ensured that the obtained resin is UV light-cured resin, has good adhesive force to the wood veneer and good flexibility, can resist hydrolysis and bending for 5-8 years, does not crack and does not turn white after being folded in half, and meets the requirements of UV resin for elastic wood veneers.

Description

technical field [0001] The application belongs to the technical field of coatings, and in particular relates to a UV photocurable resin for elastic wood veneer. Background technique [0002] UV light-curing coatings are gradually replacing traditional solvent-based coatings due to their advantages in environmental protection and energy saving. The coating methods of UV light-curing coatings in the field of woodware mainly include roller coating, spraying, etc. Among them, roller coating is the most widely used, but because the current UV light-curing coatings are easy to crack and not resistant to bending, they are only suitable for application on flat wood materials. superior. [0003] Since the special-shaped parts have various shapes and angles, when the elastic veneer is coated and wrapped, it needs various deflections and bends, so the general UV light-curable resin cannot meet this demand, and whitening will appear during the construction process. phenomenon of crack...
