Abstract
Description
この発明は、化粧板成型用含浸紙の製造方法に関し、特に、含浸紙の表面付着合成樹脂層（表面保護層）と裏面付着合成樹脂層（基材との接着層）が異種の合成樹脂で構成されている含浸紙を、縦続配置した一連の装置により連続的に製造する方法に関する。 The present invention relates to a method for producing an impregnated paper for molding a decorative board, and in particular, the surface-attached synthetic resin layer (surface protective layer) and the back-attached synthetic resin layer (adhesive layer to the base material) of the impregnated paper are different types of synthetic resins. The present invention relates to a method for continuously producing impregnated paper by a series of devices arranged in cascade.
下記特許文献に開示されているような従来の含浸紙の製造方法においては、化粧紙などの被処理紙を、樹脂液の中を通過させて表裏より樹脂液を含浸させ、乾燥機により乾燥させて巻き取っていた。
従来より含浸紙の表面機能性（硬さ、耐磨耗性、耐薬品性、耐汚染性などの表面物性、および光沢性、深みなどの意匠性）を向上させるために、高価な樹脂液を使用して含浸処理を行っていたので、裏面の接着用の含浸樹脂は機能的に無駄が大きかった。 In order to improve the surface functionality of impregnated paper (surface properties such as hardness, abrasion resistance, chemical resistance and stain resistance, and design properties such as glossiness and depth), an expensive resin liquid has been used. Since the impregnation treatment was performed, the impregnation resin for bonding the back surface was functionally wasteful.
このように従来の含浸紙の製造方法においては、表裏いずれか一面の機能性を向上させるために高価な樹脂液を使用していた。 As described above, in the conventional method for producing impregnated paper, an expensive resin liquid is used in order to improve the functionality of either one of the front and back sides.
また、表面付着樹脂の機能性を向上させる樹脂液は、裏面の基材に対する密着性が劣ることがあり、結果的に性能を低下させて含浸紙の価格を高くすることがあった。 In addition, the resin liquid that improves the functionality of the surface-adhesive resin may have poor adhesion to the base material on the back surface, resulting in a decrease in performance and an increase in the price of the impregnated paper.
また、樹脂液を含浸、乾燥処理した含浸紙をいったん巻取り、機能性を付与するために、別の樹脂液を表面または裏面に再塗布して含浸紙を作ることも行われていたが、製造工程が多くならざるを得なかった。 In addition, once impregnated paper impregnated with a resin liquid and dried, the impregnated paper was wound up once, and in order to impart functionality, another resin liquid was reapplied to the front or back surface to make an impregnated paper. There were many manufacturing processes.
そこで、この発明は、要求される表裏の機能に合わせた樹脂層を形成した含浸紙を製造する方法を提供するために考えられたものである。 Accordingly, the present invention has been conceived in order to provide a method for producing an impregnated paper having a resin layer formed in accordance with the required front and back functions.
特に、機能性向上を必要とする一面に高価な樹脂液を塗布し、紙間および他の一面には廉価な樹脂液を含浸させるように構成し、含浸樹脂の材料費を抑制して、表裏の機能を目的に合わせた含浸紙の製造方法を提供するために考えられたものである。 In particular, an expensive resin solution is applied to one surface that requires improved functionality, and an inexpensive resin solution is impregnated between the paper and the other surface to reduce the material cost of the impregnated resin. It was conceived to provide a method for producing an impregnated paper having the above functions for the purpose.
この発明の含浸紙の製造方法は、被処理紙を第１の樹脂液の中に浸漬して被処理紙に表裏より第１の樹脂液を含浸させる第１工程と、この第１の樹脂液を含浸させた被処理紙の一面から第１の樹脂液を剥ぎ取る第２工程と、この第２工程で第１の樹脂液を剥ぎ取った被処理紙の一面に、第１の樹脂液とは異種の第２の樹脂液を塗布する第３工程と、この第３工程で処理された被処理紙を乾燥させる第４工程とを経る製造方法である。 The impregnated paper manufacturing method of the present invention includes a first step of immersing a paper to be treated in a first resin liquid and impregnating the paper to be treated with the first resin liquid from the front and back, and the first resin liquid. The second step of peeling the first resin liquid from one side of the paper to be treated impregnated with the first resin liquid, and the first resin liquid on one side of the paper to be treated after peeling off the first resin liquid in the second step Is a manufacturing method through a third step of applying a different second resin liquid and a fourth step of drying the paper to be treated that has been treated in the third step.
この発明の含浸紙の製造方法は、被処理紙の一面に第１の樹脂液を塗布して紙間に予備的に含浸する第１工程と、この予備的に含浸された被処理紙を第１の樹脂液の中に浸漬して被処理紙に表裏より第１の樹脂液を含浸させる第２工程と、第１の樹脂液を含浸させた被処理紙の一面から第１の樹脂液を剥ぎ取る第３工程と、この第３工程で第１の樹脂液を剥ぎ取った被処理紙の一面に、第１の樹脂液とは異種の第２の樹脂液を塗布する第４工程と、この第４工程で処理された被処理紙を乾燥させる第５工程とを経る製造方法とすることもできる。 The method for producing impregnated paper according to the present invention includes a first step of applying a first resin liquid on one side of the paper to be treated and preliminarily impregnating between the papers; A second step of immersing in the first resin liquid and impregnating the paper to be treated with the first resin liquid from the front and back, and a first resin liquid from one side of the paper to be treated impregnated with the first resin liquid. A third step of stripping, and a fourth step of applying a second resin liquid different from the first resin liquid on one side of the paper to be treated which has stripped the first resin liquid in the third step; It can also be set as the manufacturing method which passes through the 5th process of drying the to-be-processed paper processed at this 4th process.
この発明の含浸紙の製造方法によると、要求される表裏の機能に合わせた樹脂層を形成した含浸紙を製造することができ、特に、機能性向上を必要とする一面に高価な樹脂液を塗布し、紙間および他の一面には廉価な樹脂液を含浸させるように構成しているので、含浸樹脂の材料費を抑制して、かつ、表裏の機能を目的に合わせた含浸紙を製造することができる。 According to the method for producing impregnated paper of the present invention, it is possible to produce impregnated paper in which a resin layer is formed in accordance with the required front and back functions, and in particular, an expensive resin liquid is required on one side requiring improvement in functionality. Since it is applied and impregnated with an inexpensive resin liquid between the paper and the other side, the material cost of the impregnating resin is suppressed, and the impregnated paper is manufactured with the purpose of the front and back functions. can do.
この発明の各実施形態において使用する装置は、図１に一例を示すように、第１の樹脂液を攪拌しながら貯留する樹脂液貯留槽１と、原反21から引き出された化粧紙などの被処理紙２を第１の樹脂液の中に浸漬して含浸させる第１の樹脂液槽３と、被処理紙２の下面に付着した第１の樹脂液を剥ぎ取るドクターブレード４と、被処理紙２の下面に第２の樹脂液を塗布する液上げローラ51を備えた第２の樹脂液槽５と、第１の樹脂液が含浸され、第２の樹脂液が塗布された被処理紙２を乾燥させる乾燥機（図示せず）とにより構成されている。樹脂液貯留槽１に貯留されている第１の樹脂液は、ポンプ11によって第１の樹脂液槽３に供給される。
The apparatus used in each embodiment of the present invention includes, as shown in FIG. 1, a resin liquid storage tank 1 that stores the first resin liquid while stirring, and a decorative paper drawn from the

この含浸紙を厚み８ｍｍの中密度ファイバーボード上にセットし、エンボス付き鏡面板を使用して１４５℃、２０ｋｇ／ｃｍ2で４分間熱圧成型により貼りあわせたところ、表面付着の白色樹脂が熱圧で流動してエンボス版の谷の部分に流れ込んで偏在状態となり、使用したエンボス版に同調した柄の化粧板が得られた。 When this impregnated paper was set on a medium density fiber board with a thickness of 8 mm and bonded by hot pressing at 145 ° C. and 20 kg / cm 2 for 4 minutes using an embossed mirror plate, the white resin adhered to the surface was heated. It flowed by pressure and flowed into the valley portion of the embossed plate, becoming unevenly distributed, and a decorative veneer with a pattern synchronized with the used embossed plate was obtained.
この製造方法によると、着色した含浸樹脂の使用量が少ないので、製品中の原材料費が軽減されるとともに、含浸終了後、他に転用がきかない白色チタン混入した残樹脂量も減少できて、製品を廉価に製造することができる。 According to this manufacturing method, since the amount of colored impregnated resin used is small, the cost of raw materials in the product is reduced, and the amount of residual resin mixed with white titanium that cannot be diverted after impregnation is reduced. Can be manufactured at low cost.

得られた含浸紙を厚み１２ｍｍのパーチクルボード上にセットし、撤兵石柄の凹凸を有するエンボス板を用いて、１８０℃、２５ｋｇ／ｃｍ2で、９０秒間熱圧成型により貼り合わせた。 The obtained impregnated paper was set on a particle board having a thickness of 12 mm, and was bonded by hot pressing at 180 ° C. and 25 kg / cm 2 for 90 seconds using an embossed plate having relief stone pattern irregularities.
成型板の仕上りは、使用したエンボス板の凹部に乳白色半透明の樹脂が溜まり、石張り壁材に比して遜色無い化粧板が得られた。 As for the finish of the molded board, milky white translucent resin accumulated in the recesses of the used embossed board, and a decorative board comparable to that of stone-walled wall material was obtained.
なお、この第５の実施形態において、含浸処理を実施する前に、予備的に行った紙間に含浸させて強化する処理は、含浸に使用する第１の樹脂液およびに塗布に使用する第２の樹脂液とは異なった浸透性のよい第３の樹脂液を使用することもできる。
In this fifth embodiment, before the impregnation treatment is performed, the preliminarily performed impregnation between the papers to strengthen the first resin liquid used for the impregnation and the first resin liquid used for the application. A third resin liquid having good permeability different from the
第３の樹脂液として、第１の樹脂液およびに第２の樹脂液よりも廉価な樹脂液を使用すると、さらに化粧板を安価に製造することができる。 When the first resin liquid and a less expensive resin liquid than the second resin liquid are used as the third resin liquid, the decorative board can be manufactured at a lower cost.
