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.
Claims3
A production method of 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, and
- the production method comprises the steps of:
- curing the unsaturated polyester resin composition under conditions where a temperature of a mold is 80 to 160° C. and a pressure is 5 to 100 kg/cm2;
- lowering the temperature of the mold by 30° C. or more while maintaining the pressure;
- and removing a produced coated wood composite from the mold.
A production method of 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, and
- the production method comprises the steps of:
- preliminarily pressing the unsaturated polyester resin composition to a mold under conditions where a temperature of the mold is less than 80° C. and a pressure is 5 to 100 kg/cm2;
- curing the unsaturated polyester resin composition by raising the temperature of the mold by 20° C. or more to 80 to 160° C. while maintaining the pressure;
- and removing a produced coated wood composite from the mold.
