【発明の詳細な説明】
［産業上の利用分野］
本発明は着色粉体樹脂で着色された紫外線硬化
性塗料を塗布した化粧板の製造方法に関するもの
出ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing a decorative board coated with an ultraviolet curable paint colored with a colored powder resin.
［従来の技術、従来技術の問題点］
従来、紫外線硬化性塗料（以下UVPと略す）
を塗布した化粧板は、UVPが紫外線を透過しな
ければならないため透明なものが主に用いられて
いたので模様が単調になりがちであつた。又着色
したUVPを塗布する場合は、不透明にならない
程度に着色するか又は塗膜層を薄くしなければな
らなかつた。[Conventional technology, problems with conventional technology] Conventionally, ultraviolet curable paint (hereinafter abbreviated as UVP)
Decorative boards coated with UV rays were mostly transparent because UVP had to pass through them, so the patterns tended to be monotonous. Furthermore, when applying colored UVP, the color must be applied to an extent that it does not become opaque, or the coating layer must be made thin.
［問題点を解決するための手段］
本発明は粉体の直径が１〜50μの着色粉体樹脂
をUVP100重量部に１〜30重量部添加することに
より、着色されたUVPを板状基材に厚く塗布し
た場合にも紫外線照射で容易に硬化できるもので
ある。[Means for Solving the Problems] The present invention is capable of applying colored UVP to a plate-like substrate by adding 1 to 30 parts by weight of colored powder resin having a powder diameter of 1 to 50 μm to 100 parts by weight of UVP. It can be easily cured by UV irradiation even when applied thickly.
本発明において着色粉体樹脂とは適宜着色され
た溶剤を含まない高分子量の熱可塑性樹脂または
熱硬化性樹脂を微粉砕したものである。高分子の
樹脂としてはポリエステル、エポキシ、アクリ
ル、塩化ビニル、ポリエチレン等が用いられる。 In the present invention, the colored powder resin is finely pulverized appropriately colored, solvent-free, high molecular weight thermoplastic resin or thermosetting resin. Polyester, epoxy, acrylic, vinyl chloride, polyethylene, etc. are used as the polymer resin.
着色された前記UVPが紫外線照射で硬化する
理由は、着色粉体樹脂がUVP中に若干間隙をも
つて分散しているので紫外線がその間隙を通過す
るためと考えられる。従つてUVPに紫外線の透
過性を低下させない範囲で増量剤等の充填剤を添
加する事ができる。 The reason why the colored UVP is cured by ultraviolet irradiation is thought to be that the colored powder resin is dispersed in the UVP with slight gaps, and the ultraviolet rays pass through the gaps. Therefore, fillers such as extenders can be added to UVP within a range that does not reduce the transmittance of ultraviolet rays.
以下本発明の一実施例を示す図面に基ずいて説
明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below based on the drawings.
合板、パーテイクルボード、フアイバーボード
等の有機質板、ケイ酸カルシユウム板、石綿スレ
ート板等の無機質板よりなる板状基材１の表面に
適宜下地処理層２を施す。下地処理を施す方法と
しては着色塗料の塗布、適宜絵柄模様の印刷、化
粧紙、クロスの貼着等がある。 A base treatment layer 2 is suitably applied to the surface of a plate-shaped substrate 1 made of an organic board such as plywood, particle board, fiber board, or an inorganic board such as a calcium silicate board or an asbestos slate board. Methods for performing surface treatment include applying colored paint, printing appropriate patterns, and pasting decorative paper or cloth.
次に絵柄模様層３をスクリーン印刷で形成し、
その上にポリエステル、ウレタン、アクリル、エ
ポキシ樹脂等よりなるUVP100重量部に粉体の直
径が１〜50μの着色粉体樹脂を１〜30重量部添加
してなる着色粉体樹脂含有のUVPをロールコー
ター、リバースコーター、スプレー等で20〜
500μの厚さに塗布して紫外線硬化性塗膜４を形
成する。 Next, a picture pattern layer 3 is formed by screen printing,
On top of that, roll UVP containing colored powder resin, which is made by adding 1 to 30 parts by weight of colored powder resin with a powder diameter of 1 to 50 μm to 100 parts by weight of UVP made of polyester, urethane, acrylic, epoxy resin, etc. 20~ with coater, reverse coater, spray, etc.
The ultraviolet curable coating film 4 is formed by coating to a thickness of 500 μm.
又前記着色粉体樹脂の添加された塗料を模様状
に塗布する場合にはスクリーン印刷法によるのが
好適であり、＃20〜＃130のスクリーンの紗を使
用することにより20〜500μの厚さの塗膜を任意
の模様に形成することができる。その上に必要に
応じて透明なトツプコート層５を形成する。 In addition, when applying the paint containing the colored powder resin in a pattern, it is preferable to use the screen printing method, and by using screen gauze of #20 to #130, a thickness of 20 to 500 μm can be applied. The coating film can be formed into any pattern. A transparent top coat layer 5 is formed thereon if necessary.
着色粉体樹脂の粉体の直径が1μ未満の場合は
多数の微粉体がUVPの中に均一に分散するため
紫外線を遮断してUVPの硬化を妨げる。他方直
径が50μを越す場合は該着色粉体樹脂がUVPの中
にモザイク調に点在し均質な色調のものができな
いので好ましくない。 When the diameter of the colored powder resin powder is less than 1μ, many fine powders are uniformly dispersed in the UVP, blocking ultraviolet rays and preventing the UVP from curing. On the other hand, if the diameter exceeds 50 μm, the colored powder resin will be scattered in a mosaic pattern within the UVP, making it impossible to obtain a uniform color tone, which is not preferable.
又前記着色粉体樹脂の添加量が１重量部未満の
場合は着色が不十分であり、30重量部を越す場合
は該着色粉体樹脂がUVPの中に多量に分散する
ので紫外線の透過が低下してUVPの硬化時間が
長くなつたり、硬化不良が生じることがあり好ま
しくない。 Furthermore, if the amount of the colored powder resin added is less than 1 part by weight, the coloring is insufficient, and if it exceeds 30 parts by weight, a large amount of the colored powder resin will be dispersed in the UVP, resulting in poor UV transmission. This is undesirable because it may cause the UVP curing time to become longer or to cause curing failure.
