ある。2. Description of the Related Art Conventionally, WPC treatment is well known. For example, after slicing rice stalks and impregnating a rice squirrel veneer having a thickness of 0.2 to 0.5 mm with a polyester resin solution and curing the slabs, It is used as a flooring material by making the color of the spring wood part dark with a colored adhesive and causing it to reverse the fall wood part and sticking it to the base material. This is to use natural wood veneer to reveal patterns that are not found in natural materials.

This sliced veneer is placed in a large number of treatment tanks with a 1.0 mm spacer net sandwiched between the veneers and treated with treated water. The treated water contains a surfactant. The mixing ratio of the surfactant is preferably 2 to 20% by weight. The surface tension of the liquid is reduced by a surfactant to improve the permeability to the sliced veneer, but if the blending ratio is less than 2% by weight, the effect is halved, and conversely 20% by weight. Even if it exceeds%, the effect is not significantly improved. The boiling treatment with treated water is performed at a temperature of 90 to 100 ° C. for 2.0 to 6.0 hours. When the treatment temperature is lower than 90 ° C, the degreasing effect becomes small.
When the treatment time is less than 2.0 hours, the degreasing effect is small, and when it is more than 6.0 hours, the degreasing effect is improved, but the color is dark. The degreasing rate is 5 to 20% by weight.

採用できる。The sliced veneer is degreased with treated water to change its color to brown, and then dried. If the sliced veneer has a large amount of water, the resin impregnation rate afterwards will decrease, so the lower the moisture rate of the sliced veneer, the better.
It is preferable to dry it to not more than%. Then, the sliced veneer is placed in a cylindrical impregnation tank with a spacer inserted between the veneers. Next, the impregnation tank is depressurized (mercury manometer 5.0 to 15.0 mm / Hg) with a vacuum pump, and under reduced pressure,
For example, an unsaturated polyester resin liquid is injected. After injecting the polyester resin liquid, the vacuum pump is driven for 1.0 to 2.0 hours. In this case, the resin liquid boils (because the styrene monomer has a boiling point or higher). Boiling time is 1.0
~ 2.0 Hrs. After this, the valve is opened and the impregnation tank is returned to normal pressure. Next, the pressure pump is rotated to pressurize the resin liquid. Pressure 15 to 25 kg / cm 2 , time 1.0 to 3.0
Hrs. The polyester resin liquid is composed of a polymer, a styrene monomer, and a polymerization initiator such as BPO and cobalt. The polymer is impregnated in the spring material portion and the styrene monomer is impregnated in the autumn material portion. Then, the valve is opened and the impregnation tank is returned to normal pressure to recover the polyester resin liquid. After this, the sliced veneer is taken out. Next, wipe the front and back of the sliced veneer with a waste cloth with an acetone solvent, and dry it in a drying chamber for 90 minutes.
The polyester resin is cured by drying at 8.0 ° C. for 8.0 to 10.0 Hrs. Impregnation rate of resin liquid is 100-1
20% by weight, and the surface hardness is 50 with a Barcol hardness tester.
It improved to ~ 70. As the resin liquid, a modified acrylic resin, a phenol resin, a melamine resin, a DAP resin, or the like can be used as well.

A 5 mm spacer net was placed and placed in a treatment tank, and the treatment was carried out at a temperature of 90 to 100 ° C. for 5 hours. Then, put it in the impregnation tank and reduce the pressure (mercury manometer 10.0

After injecting the unsaturated polyester resin liquid, the vacuum pump is driven for 1.0 to 2.0 hours to boil the resin liquid (because the styrene monomer is above the boiling point).
