【発明の詳細な説明】
本発明は化粧板の製造方法に関し、特に化粧単
板の表層部分を硬化した化粧板の製造方法に係る
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative laminate, and more particularly to a method for manufacturing a decorative veneer in which the surface layer portion of a decorative veneer is hardened.
従来化粧単板の表面硬度や耐摩耗性、寸法安定
性などと向上させるため、WPC（Wood Plastic
Combination）、と称される技法が利用された
り、化粧単板上に熱硬化性合成樹脂含浸紙をオー
バレイし、熱圧成型する方法が採られていた。 In order to improve the surface hardness, abrasion resistance, and dimensional stability of conventional decorative veneers, WPC (Wood Plastic
A technique called ``Combination'' was used, or a method was used in which thermosetting synthetic resin-impregnated paper was overlaid on the decorative veneer and then hot-pressure molded.
しかしながら化粧単板として桧や杉などの白色
系木肌を有する樹種を使用する場合は、公知の熱

板の極く表層だけしか硬化しない熱硬化性合成樹

つている白色木肌が消え黄色味の強い外観に変化
し商品価値が著しく低下していた。 However, when using a wood species with white skin such as cypress or cedar as a decorative veneer, using a known thermosetting synthetic resin will not only cure WPC, but also a thermosetting resin that will harden only the very surface layer of the decorative veneer. Even with the overlay method using synthetic resin-impregnated paper, the white wood skin of the decorative veneer disappeared and the appearance changed to a strong yellowish tinge, significantly reducing its commercial value.
この色調の変化は木材を水で濡らした時の色調
の変化に酷似している。一方、屈折率が1.5〜1.6
に集中している公知の熱硬化性合成樹脂で化粧単

の色調も黄色味が強くなることから木材の屈折率
は水や之等熱硬化性合成樹脂の屈折率に近いこと
が推定される。 This change in color is very similar to the change in color when wood is wet with water. On the other hand, the refractive index is 1.5-1.6
When a decorative veneer is made of WPC using a known thermosetting synthetic resin that is concentrated in It is estimated that the refractive index is close to that of resin.
故に屈折率が1.5〜1.6から大きく異なる物質を
木材組織に注入硬化させない限りこの黄色味が強
くなる現象は回避出来ない。 Therefore, unless a substance with a refractive index significantly different from 1.5 to 1.6 is injected into the wood structure and hardened, this phenomenon of increased yellowness cannot be avoided.
そこで本発明者等は鋭意検討の結果、木材の中
空組織の中に注入硬化される熱硬化性合成樹脂
が、この中空組織を完全に充填せず、その内部が
無垢の木材と同様の形状を取るつまり細胞壁の廻
りだけを充填する熱硬化性合成樹脂を考案すれば
本問題が解決されることに着目した。 As a result of intensive studies, the inventors of the present invention found that the thermosetting synthetic resin that is injected and hardened into the hollow structure of wood does not completely fill the hollow structure, and the inside of the resin has a shape similar to that of solid wood. We focused on the fact that this problem could be solved by devising a thermosetting synthetic resin that fills only the area around the cell walls.
即ち、公知の熱硬化性合成樹脂に30〜70重量部
の非共重合性低沸点溶剤を加え、之を化粧単板上
に塗布後、熱硬化性合成樹脂含浸オーバレイ紙を

とにより、木材の中空組織内で硬化した樹脂に空
洞を形成させる本発明を完成した。図に木材組織
内で硬化した熱硬化性合成樹脂の模式図を示す。 That is, 30 to 70 parts by weight of a non-copolymerizable low-boiling solvent is added to a known thermosetting synthetic resin, and this is applied onto a decorative veneer, and then an overlay paper impregnated with a thermosetting synthetic resin is overlayed and heat-pressed. By volatilizing these substances during molding, we have completed the present invention in which cavities are formed in the hardened resin within the hollow structure of the wood. The figure shows a schematic diagram of a thermosetting synthetic resin that has hardened within the wood structure.

It exhibits an elegant design with its white wood surface intact.

悪いものになつて了う。 On the other hand, in order to prevent the thermosetting resin from penetrating into the decorative veneer, an overlay paper with a significantly low impregnation rate of the thermosetting resin is used, and an adhesive thermosetting resin is interposed between the overlay paper and the decorative veneer. Although it is possible to consider a method in which the decorative veneer and the overlay paper are not allowed to adhere to each other, this method results in insufficient adhesion between the decorative veneer and the overlay paper, resulting in extremely poor durability.
つまり本発明方法は化粧単板とオーバレイ紙と

法を提供するものである。 In other words, the method of the present invention provides a method for producing a surface-cured decorative veneer that achieves sufficient interfacial adhesion between the decorative veneer and the overlay paper, and also does not impair the white wood grain design of the decorative veneer.

硬度が著しく低下して了う。 The addition rate is preferably 30 to 70 parts by weight. If it is less than 30 parts by weight, the cavities shown in Figure 1 are small, resulting in a slight yellowish tinge, and if it is more than 70 parts by weight, the thermosetting resin does not form a continuous matrix, resulting in a significant decrease in surface hardness. .
本発明に使用される含浸用原紙には薄葉紙、レ
