Abstract
To provide: a coated wood composite having surface properties such as transparency, smoothness, gloss, uniformity, and depth, and excellent in various physical properties such as durability and strength; and a method for producing such a coated wood composite efficiently and easily. A coated wood composite produced by placing an unsaturated polyester resin composition on a decorative veneer and heat-pressing the decorative veneer and the composition placed thereon to mold the composite, wherein the unsaturated polyester resin composition comprises: an unsaturated polyester; a polymerizable monomer; and an isocyanate component essentially including an aliphatic diisocyanate.
Claims5
A method comprising:
- placing a composite including a decorative wood veneer having an unsaturated polyester resin composition on at least one of its outer surfaces in a mold such that the resin composition is exposed, the unsaturated polyester resin composition having a thickness from 200 to 1500 μm and comprising an unsaturated polyester, a polymerizable monomer, and an isocyanate component including an aliphatic diisocyanate;
- deaerating bubbles in the unsaturated polyester resin composition;
- after the unsaturated polyester resin composition has been deaerated, curing the unsaturated polyester resin composition in the mold at a temperature of 80 to 160° C. and a pressure of 5 to 100 kg/cm2;
- lowering the temperature of the mold by 30° C. or more while maintaining the pressure in the mold;
- and thereafter
- removing the composite from the mold with the unsaturated polyester resin composition being exposed.
