本発明は電子線硬化型樹脂を用いた化粧板の製法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative board using an electron beam curable resin.
従来より製造されているメラミン化粧板やジアリルフタ
レート化粧板は、含浸性を有する紙にメラミン樹脂等を
含浸させ、これを基板の上に重ねて高温高圧の条件で製
造している。その為、樹脂の含浸工程および加熱加圧工
程が必要となり、工程の多いこと、時間のかかることが
大きな問題点となっていた。Conventionally manufactured melamine decorative boards and diallyl phthalate decorative boards are manufactured by impregnating impregnating paper with melamine resin, etc., and stacking this on a substrate under high temperature and high pressure conditions. Therefore, a resin impregnation step and a heating and pressurizing step are required, and the large number of steps and time required have been major problems.
そこで、含浸工程に代って紙の表面に樹脂を塗布して乾
燥したものを、接着剤を介して基板に貼着するという方
法が考えられたが、この方法では表面に塗布した樹脂が
紙の内部には完全に浸透しておらず、浸漬含浸の方法に
よって製造した化粧板に比較してその性能は劣るもので
あった。Therefore, instead of the impregnation process, a method was considered in which resin was applied to the surface of the paper, dried, and then attached to the substrate using an adhesive. However, in this method, the resin applied to the surface of the paper It did not completely penetrate into the inside of the laminate, and its performance was inferior to that of decorative laminates manufactured by the immersion impregnation method.
本発明は以上のような点を改良すべくなされたものであ

る。The present invention has been made to improve the above-mentioned points. Before drying the resin applied to the surface of the paper, a release film is layered on top of it, and then the resin is placed on the substrate. By applying pressure, the resin applied to the surface penetrates into the inside of the paper and oozes out to the back side of the paper, and this is used as an adhesive to adhere to the substrate. Moreover, the resin applied is an electron beam curing resin. By using this method, a decorative board with surface performance equivalent to that of high-pressure melamine can be manufactured.
以下図面に従って本発明の詳細な説明する。The present invention will be described in detail below with reference to the drawings.
まず第１図に示すように含浸性を有する紙（１）を用意
する。紙の表面には必要に応じて任意の模様（２）を施

が得られる。Next, as shown in Fig. 3, the paper (1) is placed with its side facing the base material (5), and the entire paper is pressurized using a pressure device such as a pressure roller (6). The electron beam curing resin (3) applied to the surface is allowed to penetrate into the inside of the paper and into the back surface. In this state, electron beams are irradiated from above the releasable film to harden the electron beam-curable resin present on the surface and inside of the paper and on the back side of the paper, thereby bonding the resin, paper, and base material. Then, by peeling off the release film, a decorative material (8) as shown in Fig. 4 is obtained.
is obtained.
次に本発明の構成要素を説明する。Next, the constituent elements of the present invention will be explained.
含浸性を有する紙（１）としては、５０〜１２０Ｍのチ
タン紙、３０〜８０楓゛の透明紙等が使用でき、その表
面に施される模様（２）は、木目模様、石目模様、その
他任意に選択できる。As the impregnating paper (1), titanium paper of 50 to 120 M, transparent paper of 30 to 80 M, etc. can be used, and the pattern (2) applied to the surface thereof may be a wood grain pattern, a stone grain pattern, Others can be selected arbitrarily.
電子線硬化型樹脂（３）としては、ウレタン系、アクリ
ル系、アクリルウレタン系、エポキンアクリル系、不飽
和ポリエステル系、ジアリルフタレート系、等の樹脂の
モノマー、オリゴマー、プレポリマーより構成されるも
のが使用でき、電子線の照射によって短時間で硬化し、
しかも高圧メラミン化粧板のような硬い表面が得られろ
。The electron beam curable resin (3) is composed of monomers, oligomers, and prepolymers of resins such as urethane, acrylic, acrylic urethane, Epoquin acrylic, unsaturated polyester, diallyl phthalate, etc. can be used, cures in a short time by irradiating with electron beam,
Moreover, you can obtain a hard surface like high-pressure melamine decorative board.
離型性を有するフィルム（４）としてはポリエステル系
フィルム、ポリプロピレン系フィルム、等が用いられ、
透明不透明は問わない。又、その厚さも特に限定はない
。なお、得られろ化粧板の表面の光沢等は使用する離型
性を有するフィルム（４）の表面と同じになるので、該
フィルムの樹脂と接触する側の表面の光沢を任意に調節
することによって化粧材の表面状態をコントロールする
ことができる。As the film (4) having mold releasability, a polyester film, a polypropylene film, etc. are used,
Transparent or opaque does not matter. Moreover, there is no particular limitation on its thickness. Incidentally, the gloss etc. of the surface of the obtained decorative board will be the same as the surface of the film (4) having mold releasability used, so the gloss of the surface of the film on the side that comes into contact with the resin can be adjusted as desired. This makes it possible to control the surface condition of decorative materials.
基材（５）としては、樹脂含浸紙、合成樹脂ソート、そ
の他のソート状物、あるいは合板、パーチクルボード、
突板、無機質板、金属板、その他の板状物、およびこれ
らを２種類以上組み合わせたものが使用できる。As the base material (5), resin-impregnated paper, synthetic resin sort, other sort-like materials, plywood, particle board,
A veneer, an inorganic plate, a metal plate, other plate-like materials, and a combination of two or more of these can be used.
加圧装置としては、図示した加圧ローラーの他に、１広
フ０レスイ艮、ユンＦｌ／スヘルト状゛の市口尺殻貫等
も使用できるが、生産性の点を考慮すれば連続的に加圧
できるローラー状のものが好ましい。As a pressure device, in addition to the pressure roller shown in the figure, a 1-wide flat roller, a Yun-Fl/Schelt-like Ichiguchi-shaku shell, etc. can be used, but from the viewpoint of productivity, it is possible to use a continuous A roller-shaped material that can be pressurized is preferred.
なお、紙の表面に塗布する樹脂は紙の表面に樹脂層を形
成して高圧メラミン化粧板と同等の表面性能を確保し、
紙の内部に浸透して紙間強度を向上させるとともに紙の
層を樹脂化し、更に紙の裏面に浸み出して基材との接着
剤としての役割を果たすものであるから、その塗布量は
多い方が良く、具体的には使用する紙の重量よりも多く
塗布することが有効である。The resin applied to the surface of the paper forms a resin layer on the surface of the paper to ensure surface performance equivalent to high-pressure melamine decorative board.
It penetrates into the inside of the paper to improve interpaper strength and turns the paper layer into a resin, and it also seeps into the back side of the paper and acts as an adhesive to the base material, so the amount of application is limited. More is better; specifically, it is effective to apply more than the weight of the paper used.
離型性を有するフィルムを用いる最大の理由は、電子線
硬化型樹脂が未硬化の状態でロール等で加圧するので樹
脂がロール等に付着するのを防ぐ為である。The main reason for using a film having mold releasability is to prevent the resin from adhering to the rolls etc. since the electron beam curable resin is pressurized with a roll etc. in an uncured state.
以上のような本発明の方法によれば次のような数々の効
果が得られろ。According to the method of the present invention as described above, the following numerous effects can be obtained.
