This is the easiest method, but other methods include gluing wood veneers together with water-based adhesive, sewing them together, or attaching multiple wood veneers to the surface of a long sheet of non-woven fabric. There is a method of pasting them in a continuous manner. It goes without saying that the wood veneers connected in the longitudinal direction include long wood veneers with complex patterns such as a checkered pattern, an arrow pattern, and a wickerwork pattern.
この発明における重要な構成は、長尺の木質単板を加熱

式であったWPC単板の生産を連続式にすることができ
るようになる。An important feature of this invention is that a long wooden veneer is continuously immersed in a heated synthetic resin or oil solution. In addition, the heating of the wood veneer softens the wood structure, making it easier for moisture and air in the wood veneer to escape to the outside, and as a result, the wood veneer is more likely to be impregnated with synthetic resin liquid, etc. , the production of WPC veneers, which was conventionally done in batches, can now be done in a continuous manner.
加熱温度は100℃以上が好ましい。というのは100
″Cを越えると木質単板中の水分が蒸発して合成樹脂液
等と置換されやすいからである。The heating temperature is preferably 100°C or higher. That is 100
This is because if the water content exceeds "C", the moisture in the wood veneer will easily evaporate and be replaced with synthetic resin liquid or the like.
なお、合成樹脂あるいは油脂類の液を加熱すると同時に
減圧法や加圧法を併用することによってさらに能率よく
木質単板中に合成樹脂液等を含浸させることができる。Note that by heating the synthetic resin or oil and fat liquid and simultaneously using a pressure reduction method or a pressurization method, the synthetic resin liquid etc. can be impregnated into the wood veneer more efficiently.

ヤを用いてもよいし、熱ロールプレスや平盤熱プレスを
用いてもよい。The wood veneers impregnated with synthetic resins or oils and fats and continuously taken out from the impregnation tank are squeezed out of the excess liquid by squeezing rolls, if necessary, and then hardened by appropriate means. Possible curing methods include a method of leaving it as is, a method of accelerating curing by heating, and a method of using ultraviolet rays or electron beams. Note that a dryer, a hot roll press, or a flat plate hot press may be used for heating.
