【発明の詳細な説明】 〔技術分野〕 この発明は、温水パイプ、電気ヒータ等の床暖房器具の
上下面やその周辺で使用される耐熱性木質パネルの製造
方法に関するものである。Description: TECHNICAL FIELD The present invention relates to a method for producing a heat-resistant wood panel used on the upper and lower surfaces of a floor heating appliance such as a hot water pipe and an electric heater and in the vicinity thereof.
近時、温水パイプ、電気ヒータ等の床暖房器具を床面の
表面や内部に配置し、床面から暖房することが行われて

究が多い。Recently, floor heating appliances such as hot water pipes and electric heaters are placed on the surface of the floor or inside the floor to heat the floor. Among them, a system in which a heating appliance is arranged on the lower surface of a floor material having a wooden pipe on the surface is particularly good in terms of appearance and walking sensation, and therefore, there are many studies in this direction.
この場合、暖房器具の寒熱のくり返しや乾湿のくり返し

とは、コストが高くなるうえ、均一に樹脂処理できず、
反りやねじれの原因となるという問題があった。In this case, cracks, warps, push-ups, blinds, etc. were likely to occur in the floor material due to repeated cold heat and repeated dry and humid conditions of the heating equipment. Therefore, for the purpose of imparting heat resistance to the floor material, it has been proposed to perform a resin impregnation treatment (hereinafter, simply referred to as a resin treatment), but the resin treatment of the entire floor material results in high cost and Resin cannot be treated uniformly,
There was a problem of causing warpage and twist.

制約が多く、耐クラック性能にも若干劣っていた。Therefore, as shown in FIG. 2, a wood pipe 21 having a wood veneer 21 (plywood, fiber board, particle board, etc.) bonded to a surface of a wood veneer 21 and a resin treatment to improve heat resistance. 22 was used and attached directly or through an electric heater 24 onto the reinforcing plywood 23 to obtain the heat resistant floor material 25 or the floor heating panel 26. As a resin impregnation treatment method for the wood panel 22, as shown in FIG. 3, a resin-treated wood veneer 21 and a resin-treated wood base material 20 are bonded together (hereinafter referred to as (I) method). , A method of laminating the untreated wood veneer 21 and the untreated wood veneer 20 together and performing resin treatment (hereinafter referred to as the (II) method) has been proposed. Since both the base material 20 and the base material 20 are resin-rich, it is difficult to bond the both, and strict control of the adhesion conditions is required. Further, in the method (II), the stress generated during bonding remains, the warpage is large, there are many process restrictions, and the crack resistance is slightly inferior.

熱性木質パネルの製造方法を提供することである。The object of the present invention is to reduce the restrictions on the bonding conditions, reduce the warpage during the panel production, further improve the workability, improve the crack resistance, and evenly and stably color the wood veneer. It is an object of the present invention to provide a method for manufacturing a heat resistant wood panel that can be manufactured at low cost.

着色剤が添加された樹脂の使用量が少なくて済み、着色
剤の使用量の管理も容易になる。As described above, according to the present invention, of the wood base material and the wood veneer to be bonded to each other, the wood veneer is not resin-treated before the bonding, and therefore the bonding process is performed under normal bonding conditions. You can In addition, since the wood base material is treated with resin before bonding, it has less moisture migration, is highly rigid, has less warpage, and has improved crack resistance, making it suitable for use as a surface material for floor materials for floor heating. It is possible and easy to manufacture. Also, since the wood veneer is not resin-treated before bonding, it is not double resin impregnated,
The resin to which the colorant is added provides uniform and stable coloring. Furthermore, since the wood base material is treated with resin before bonding, when the whole resin is impregnated with the resin to which the colorant is added, the wood base material is hardly impregnated with the resin, and the wood base material is hardly impregnated. The amount of the resin added with the colorant that is impregnated into the wooden base material having a larger volume than that of the plate is small, and the amount of the colorant used is easily controlled.

る。Examples of the resin used for the resin treatment include polymethacrylic acid methyl ester, polystyrene, unsaturated polyester and the like. For the resin treatment, a normal pressure impregnation method in which the resin is impregnated under normal pressure, or a reduced pressure / pressure impregnation method in which the pressure is reduced and then the pressure is impregnated can be employed. After impregnation with the resin, the resin is completely cured by heating or heating and pressing.

る。According to the present invention, of the wood base material and the wood veneer to be bonded to each other, the wood veneer is not resin-treated before bonding, so that the bonding process can be performed under normal bonding conditions. In addition, since the wood base material is treated with resin before bonding, it has less moisture movement, is highly rigid, has less warpage, and has improved crack resistance, making it suitable for use as a floor material for floor heating. It is possible and easy to manufacture.
Further, since the wood veneer is not resin-treated before being laminated, it is uniformly and stably colored with the resin to which the colorant is added without being subjected to the resin impregnation treatment twice. Furthermore, since the wood base material is resin-treated before bonding, when the whole is impregnated with the resin to which the coloring is added, the wood base material is hardly impregnated with the resin and the wood veneer Compared with, the amount of the resin to which the coloring agent impregnated in the wooden base material having a larger volume is used less, the cost is low, and the use amount of the coloring agent can be easily controlled.
