【発明の詳細な説明】
本発明は光硬化型上塗塗料を使用した紙貼り化粧板の製
造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 paper-bound decorative board using a photocurable top coating.
従来の塗料の塗膜硬化にはおもに熱エネルギーが使用さ
れてきたが、光硬化塗料では紫外線エネルギーによって
塗膜の硬化反応が起り、短かい時間で硬化乾脈が可能で
あり、又、加熱乾燥が困難であった素材、たとえば合板
、木材、パーチクルボード等の木質繊維板の場合加熱せ
ずに架橋硬化形の塗膜を形成することができる等のメリ
ットもある。Heat energy has been mainly used to cure the film of conventional paints, but with photocurable paints, the curing reaction of the paint film occurs with ultraviolet energy, and it is possible to cure the film in a short period of time. In the case of materials that have been difficult to cure, such as plywood, wood, and wood fiber boards such as particle board, there are also advantages such as the ability to form cross-linked and cured coatings without heating.
本発明は紙貼り化粧板の上塗塗料に光硬化型上塗塗料を
使用して品質の優れた化粧板を得る構想を提供せんとす
るものである。The present invention aims to provide a concept for obtaining a decorative board with excellent quality by using a photocurable top coat as the top coat for a paper-bound decorative board.

ｍ２の薄葉紙を接着剤が中層部まで浸透するように貼着
し、浸透性大の自己硬化性樹脂を接着剤浸透部まで浸透

。In the present invention, adhesive is applied to a desired base material and 15 to 30 gr/g
A thin paper of m2 is pasted so that the adhesive penetrates to the middle layer, and a self-curing resin with high permeability is applied so that it penetrates to the adhesive penetration part.
The present invention relates to a method for producing a decorative board, which is characterized by applying a photo-curable top coat, irradiating it with ultraviolet rays, and curing it.
所望基材（合板、木質繊維板、石綿スレート板等）に熱
可塑性接着剤（酢ビエマルジョン等）と薄葉紙に対して
浸透性のよい熱硬化性接着剤（尿素樹脂、メラミン樹脂
等）とを混合した接着剤を４５〜１００ｇｒ／ｍ２塗布
し、指触乾燥程度の段階で１５〜３０ｇｒ／ｍ２の薄葉
紙を接着剤が中層部まで浸透するように貼着する。A thermoplastic adhesive (vinyl vinegar emulsion, etc.) and a thermosetting adhesive (urea resin, melamine resin, etc.) that has good permeability to thin paper are applied to the desired base material (plywood, wood fiber board, asbestos slate board, etc.). The mixed adhesive is applied at 45 to 100 gr/m2, and when it is dry to the touch, a thin paper of 15 to 30 gr/m2 is attached so that the adhesive penetrates into the middle layer.
貼着方法としてはラミネート法、プレス法等がある。Examples of pasting methods include a laminating method and a pressing method.
この場合、接着剤としては薄葉紙への浸透性のよいもの
を一種以上加えた接着剤を使用する。In this case, the adhesive used is one or more adhesives that have good permeability into thin paper.
又、使用する積層紙としては紙間剥離防止の為に樹脂浸
透が容易な薄葉紙を用いる。In addition, the laminated paper used is thin paper that is easily penetrated by resin in order to prevent paper separation.
この場合、薄葉紙に種々の印刷を施しておけばよい。In this case, the thin paper may be printed in various ways.
薄葉紙貼着後、浸透性のよい自己硬化性樹脂（ラッカー
、湿気硬化型ウレタン等）を１８〜４５ｇｒ／ｍ２塗布
する。After pasting the thin paper, a self-curing resin with good permeability (lacquer, moisture-curing urethane, etc.) is applied at a rate of 18 to 45 gr/m2.
この場合、薄葉紙の接着剤浸透部まで該樹脂が浸透して
未含浸層を生じないように塗布後、所望時間経過させた
後乾燥させる。In this case, after application, the resin is dried after a desired period of time so that the resin does not penetrate into the adhesive-penetrated portion of the thin paper to form an unimpregnated layer.
この意味は、樹脂強化して薄葉紙の紙間剥離を防止する
ことと、次工程での光硬化型塗料が薄葉紙中へ浸透しな
いように薄葉紙の空隙を充填することである。The purpose of this is to strengthen the resin to prevent the thin paper from peeling, and to fill the voids in the thin paper so that the photocurable paint in the next step does not penetrate into the thin paper.
薄葉紙を樹脂強化した後、光硬化型上塗塗料を９０〜２
００ｇｒ／ｍ２塗布する。After reinforcing the thin paper with resin, apply a light curing top coat of 90-2.
Apply 00gr/m2.
薄葉紙は既に樹脂強化されている為、光硬化型上塗塗料
は薄葉紙には浸透せず、薄葉紙中の気泡が置換によって
塗膜中へ出てくる可能性は全くない。Since the tissue paper is already reinforced with resin, the photocurable top coating does not penetrate into the tissue paper, and there is no possibility that air bubbles in the tissue paper will come out into the coating film by displacement.
その為次工程での紫外線照射による上塗塗料硬化に際し
ては均一に塗膜を硬化さすことができ、上塗塗料が紙に
浸透して光硬化が阻害される可能性も全くない。Therefore, when curing the top coat by UV irradiation in the next step, the coating film can be uniformly cured, and there is no possibility that the top coat will penetrate into the paper and inhibit photocuring.
従来のポリエステル化粧板製造法はセロハン法、フロー
コーター法共に塗装に長時間（２０〜３０分）を要した
が、紫外線を利用することにより、又上述の製造方法を
採用することによって短時間（約１分）で品質の優れた
化粧板を得ることができた。Conventional polyester decorative board production methods require a long time (20 to 30 minutes) for both the cellophane method and flow coater method, but by using ultraviolet rays and adopting the above-mentioned manufacturing method, the coating process can be completed in a short time (20 to 30 minutes). A decorative board of excellent quality could be obtained in about 1 minute).
本発明中使用する紙として１５〜３０ｇｒ／ｍ２の薄葉
紙に限定した理由は、該紙の中層部で接着剤とシーラー
処理目的の自己硬化性樹脂とが結合して未含浸層を生じ
ないために必要な条件であり又、光硬化型上塗塗料層と
薄葉紙との間に自己硬化性樹脂層を介在させることは、
上塗塗料の浸み込み防止と、薄葉紙中の気泡が置換して
塗膜中に出てくることを防止する為であり、そのことに
よって上塗塗料全体を紫外線によって硬化さすことがで
きる。The reason why the paper used in the present invention is limited to thin paper of 15 to 30 gr/m2 is to prevent the adhesive from bonding with the self-curing resin for sealer treatment in the middle layer of the paper, resulting in an unimpregnated layer. This is a necessary condition, and interposing a self-curing resin layer between the photocurable top coat layer and the thin paper is a necessary condition.
This is to prevent the top coat paint from penetrating and to prevent air bubbles in the thin paper from being replaced and coming out into the coating film, thereby allowing the entire top coat paint to be cured by ultraviolet rays.
本発明に使用する光硬化用樹脂としては不飽和ポリエス
テル系、アクリル系、アルキツド系、変性ウレタン系、
変性エポキシ系があり、これらの樹脂はビニルモノマー
で稀釈して使用する。Photocuring resins used in the present invention include unsaturated polyester, acrylic, alkyd, modified urethane,
There are modified epoxy systems, and these resins are used after being diluted with vinyl monomer.
又、目的に応じ光増感剤、顔料を使用する。Also, photosensitizers and pigments are used depending on the purpose.
顔料を使用する場合は、紫外線通過率の大きいものを選
択することが必要である。When using pigments, it is necessary to select pigments that have a high UV transmittance.
