この発明は建築材料や家具材料に使用する強化板の製造
方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing reinforcing boards used for building materials and furniture materials.

含浸させて強化木質単板を製造し、これを接着剤を介し
て基材に接着することは公知技術であった。It is a known technique to impregnate a wooden veneer with a synthetic resin by a vacuum bonding method or a pressure impregnation method to produce a reinforced wooden veneer, and then bond this to a base material via an adhesive.

も非常に時間がかかり、生産性が低い欠点があった。[Problems to be Solved by the Invention] As in the past, simply immersing a wooden veneer in a synthetic resin liquid under reduced pressure or increased pressure does not allow the synthetic resin liquid to be reliably impregnated into the wooden veneer in a short period of time. Furthermore, it is very time consuming to bond this wooden veneer to a base material using an adhesive to produce a reinforced board, which has the drawback of low productivity.

When manufacturing a reinforced veneer by impregnating a wooden veneer with a synthetic resin, the wooden veneer is soaked in one heated liquid of the two-component synthetic resin and taken out, and the wood veneer is soaked with the two-component synthetic resin. This relates to a method for producing a reinforced board, characterized in that the wood veneer is coated or impregnated with the other material, and then the wood veneer is adhered to the base material via an adhesive containing an effect accelerator of a two-component synthetic resin. .

合成樹脂液等と置換されやすいからである。In this invention, one of the most important features is to immerse the wooden veneer in a heated liquid in which one of the two-component synthetic resins is heated. This is because when a synthetic resin liquid is heated, its viscosity decreases, making it more likely to be impregnated into the wood veneer, and heating the wood veneer softens the wood structure and removes moisture and air in the wood veneer. This is because it becomes easier to escape outside, and as a result, the wooden veneer is more likely to be impregnated with synthetic resin liquid, etc. The heating temperature is preferably 100°C or higher. This is because when the temperature exceeds 100°C, the moisture in the wood veneer tends to evaporate and be replaced with synthetic resin liquid or the like.

役立つ。また硬化方法としては、そのまま放置しておく
方法、加熱して硬化を促進させる方法等が考えられる。The wood veneer impregnated with one of the two-component synthetic resins as described above is taken out of the heated solution, and after removing the excess impregnating solution with hot rolls or cold rolls, the other of the two-component synthetic resins is impregnated with the other half of the two-component synthetic resin. Apply or impregnate, and if necessary, remove excess cold cloth or impregnation by the same method as in 1-1. It is adhered to the material and hardened by appropriate means. Another important feature of the present invention is to use an adhesive containing a curing accelerator for this two-component synthetic resin. Such a configuration dramatically improves the productivity of manufacturing the reinforcing plate. Here, the base material includes sheet materials such as paper and nonwoven fabric in addition to board materials such as plywood, hardboard, and particle board.When applying the other part of the two-component synthetic resin, the coating liquid is heated. However, materials such as benzoyl peroxide, which easily decompose when heated, cannot be heated.Also, when impregnating, it is also possible to heat the impregnating solution. Heating the impregnating liquid will help it penetrate into the wood veneer and accelerate curing. Further, as a curing method, there are a method of leaving it as is, a method of accelerating curing by heating, and the like.

ックが生じることを防止している。In addition, if the hardening accelerator is spray applied to the surface of a wooden veneer placed on the surface of the base material via an adhesive, and then hot pressed with a flat plate heat press, the surface of the adhesive synthetic resin-impregnated veneer will not harden. and surface cracks are less likely to occur during manufacturing. this is,
The adhesive hardens first and 1. When the synthetic resin-impregnated veneer is then strengthened, it prevents cracks from forming on the surface due to shrinkage of the synthetic resin during curing.
