。[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a method for obtaining a decorative board by impregnating wood with a specific photocurable resin and photocuring it. be.
従来から、木材に光硬化性樹脂を含浸させ光照射のみに
よって硬化させようとする試みはあったが、木材内部に
含浸した樹脂が光硬化性に乏しいために、有機過酸化物
を併用し、表面を光硬化した後加熱して内部を硬化させ
ている場合がすべであった。Previously, there have been attempts to impregnate wood with a photocurable resin and cure it only by light irradiation, but since the resin impregnated inside the wood has poor photocurability, organic peroxides were used in combination. In all cases, the surface was photocured and then the interior was cured by heating.
然しなから、このような方法では、硬化が速やかで、化
粧板製造の工数を著しく削減出来る可能性のある、光硬
化システムを利用するメリットに欠ける欠点があった。However, such a method has the drawback that it lacks the advantage of using a photocuring system, which cures quickly and has the potential to significantly reduce the number of man-hours for manufacturing decorative laminates.
本発明者らは、光硬化性樹脂を含浸させて、他の手数を
併用することなく、光照射することにより表面層のみで
はなく、今迄困難視されていた木材内部に含浸された樹
脂迄も硬化させ、以て優れた物性を有する化粧板の研究
を進めて来たが、意外にも光硬化性樹脂の構造、並びに
組成を特定すれば目的を達成出来ることを知り、本発明
を完成することが出来た。The present inventors impregnated the wood with a photocurable resin and irradiated it with light without using any other procedures, thereby improving not only the surface layer but also the resin impregnated inside the wood, which had been considered difficult until now. We have been conducting research on decorative laminates that have excellent physical properties by curing the resin, but surprisingly, we discovered that we could achieve our goals by specifying the structure and composition of the photocurable resin, and completed the present invention. I was able to do it.
即ち本発明は、

部迄均−に硬化させることよりなるものである。That is, the present invention provides: (1) an epoxy resin having two or more epoxy groups in one molecule, and acrylic acid and/or methacrylic acid (hereinafter referred to as
(hereinafter simply referred to as epoxyl acrylate resin) 20~
90% by weight, (2) a resin represented by the general formula (wherein R4 is hydrogen or a methyl group, R2 is hydrogen, an alkyl group, an aralkyl group, or an aryl group, and m is an integer of 1 or 2); Monoacrylate or monomethacrylate having a ring structure (
Using a photocurable resin obtained in combination with 80 to 10% by weight of mono(meth)acrylate having an alicyclic structure and +310.1% or more of a photoreaction initiator, a thin wood board is completely coated to the inside. The method consists of impregnating the resin with a liquid and then uniformly curing the inside by irradiating it with light.
本発明で組成物を特定した理由は次のように示される。 The reason for specifying the composition in the present invention is as follows.
エポキシルアクリレート樹脂は光硬化性に優れ、木材内
部に含浸された樹脂でも硬化可能であるが、粘度が高く
、実用上は稀釈子ツマ−の併用が必要となる。Epoxyl acrylate resin has excellent photocurability and can be cured even when the resin is impregnated inside wood, but it has a high viscosity and requires the use of a diluent in practical use.
従来はこの稀釈用上ツマ−としては、多価アルコールの
アクリル酸エステル、例えばトリメチロールプロパント
リアクリレート、１，６−ヘキザンジオールジアクリレ

。Conventionally, acrylic esters of polyhydric alcohols, such as trimethylolpropane triacrylate, 1,6-hexanediol diacrylate, neopentyl glycol diacrylate, triethylene glycol diacrylate, etc., have been used in combination as diluting diluters. It's here.
然し、これら多価アルコールのアクリレートを併用した
光硬化性樹脂は、木材に含浸、硬化させると、寒暖の繰
返シこより、木目に沿ってクランクが発生することが見
出された。However, it has been found that when these photocurable resins containing polyhydric alcohol acrylates are impregnated into wood and cured, cranks occur along the wood grain due to repeated heating and cooling.
反面、文献に記載されているような既存の単官能モノマ

クリル酸メチルを始めとするメタクリル酸エステル類は
、エポキシルアクリレート樹脂と併用した時に、著しく
光硬化性が遅くなり、木材内部に含浸した部分が硬化せ
ず、事実上有用な化粧板を与えない。To give an example of those mentioned in 2.3, when styrene and methacrylic acid esters including methyl methacrylate are used in combination with epoxy acrylate resin, the photocurability is significantly slowed down, and the parts impregnated inside the wood are does not cure and yield virtually no useful veneer.
アクリロニトリルなどは揮発性と毒性の点から問題であ
るし、ビニルピロリドンは水溶性があり、硬化性の点か
らも全部を用いるわけにはいかない。Acrylonitrile and the like are problematic in terms of volatility and toxicity, and vinylpyrrolidone is water-soluble, so not all of it can be used in terms of curability.
更に、アクリル酸エステル類は臭気、皮膚刺激性、軟か
いといった諸欠点から、実用性のあるものが乏しかった
。Furthermore, acrylic acid esters have few practical uses due to various drawbacks such as odor, skin irritation, and softness.

A suitable thickness is . Further, the moisture content of the thin plate is preferably 20% or less.
本発明による光硬化性樹脂使用の特長の一つに、含浸、
硬化後、この種の化粧仮にあり勝ちな、木目に沿ったク
ランクが発生し難いことがあげられる。実用上の硬度は
十分である。One of the features of using photocurable resin according to the present invention is impregnation,
After curing, it is difficult to produce cranks that follow the wood grain, which is common with this type of cosmetic. Hardness is sufficient for practical use.
本発明による光硬化樹脂は必要に応じて着色することは
自在である。また木材に樹脂を含浸させる時に、減圧、
加圧等の処置をとることも自由に行える。The photocurable resin according to the present invention can be colored as necessary. Also, when impregnating wood with resin, reduced pressure,
Measures such as pressurization can also be taken freely.
次に本発明の理解を助けるために、以下に実施例を示す
。Next, examples will be shown below to help understand the present invention.
