Description
本発明は、基材を熱硬化性樹脂化粧板で一連に被覆した積層板における、耐熱性及び生産性に優れた接着加工方法に関する。 The present invention relates to an adhesion processing method excellent in heat resistance and productivity in a laminated board in which a base material is continuously coated with a thermosetting resin decorative board.
熱硬化性樹脂化粧板を基材の形状に沿って一連に被覆した積層板は、表面硬度や耐熱性に優れ、意匠性にも富むため、各種カウンターや、キッチンの扉等に広く用いられている。このような積層板の製造方法として、基材と熱硬化性樹脂化粧板の平面部を貼り合わせた後、基材の側面部に沿うように熱硬化性樹脂化粧板を折り曲げつつ貼り合わせ、さらに、必要に応じて基材の裏面部に沿うように熱硬化性樹脂化粧板を折り曲げつつ貼り合わせることにより、基材を熱硬化性樹脂化粧板でＬ字状やコの字状に被覆した積層板を得る方法が知られている。 Laminated boards with a series of thermosetting resin decorative boards coated along the shape of the substrate are excellent in surface hardness, heat resistance, and design, so they are widely used in various counters, kitchen doors, etc. Yes. As a method for producing such a laminated board, after bonding the base portion and the flat portion of the thermosetting resin decorative plate, the thermosetting resin decorative plate is folded and bonded along the side surface portion of the base material, If necessary, the base material is laminated in a L-shape or U-shape by folding the thermosetting resin decorative plate along the back surface of the base material while bending it. A method for obtaining a plate is known.
従来、基材と熱硬化性樹脂化粧板の曲面部の貼り合わせには初期接着力に優れたホットメルト接着剤が用いられており、生産性には優れているものの、積層板の耐熱性の点で改良の余地があった。一方、耐熱性に優れる反応型接着剤を用いた場合、初期接着力に劣るため基材と熱硬化性樹脂化粧板を貼り合わせてから曲げるまでに一定の養生時間が必要となり、生産性が低下したり仕掛品ができる等の問題があった。
本発明の課題は、積層板の耐熱性及び生産性に優れる、積層板の接着加工方法を提供することである。 The subject of this invention is providing the adhesion processing method of a laminated board which is excellent in the heat resistance and productivity of a laminated board.
本発明は、基材を熱硬化性樹脂化粧板で一連に被覆した積層板の製造方法であって、ポリウレタン反応性ホットメルト接着剤及び非反応性ホットメルト接着剤が併用されることを特徴とする積層板の製造方法である。 The present invention is a method for producing a laminated board in which a base material is coated with a thermosetting resin decorative board in a series, wherein a polyurethane reactive hot melt adhesive and a non-reactive hot melt adhesive are used in combination. It is the manufacturing method of the laminated board to do.
本発明の製造方法によれば、基材と熱硬化性樹脂化粧板を貼り合わせてからすぐに曲げ加工を行うことができるため、生産性に優れる。また、本発明の製造方法によって製造された積層板は耐熱性に優れるため、各種カウンターや、キッチンの扉に好適である。 According to the production method of the present invention, since the bending process can be performed immediately after the base material and the thermosetting resin decorative board are bonded together, the productivity is excellent. Moreover, since the laminated board manufactured by the manufacturing method of this invention is excellent in heat resistance, it is suitable for various counters and a kitchen door.
以下、本発明について詳細に説明する。本発明における積層板とは、基材を熱硬化性樹脂化粧板で一連に被覆したものである。基材としては、単板、合板、集成材、中密度繊維板（ＭＤＦ）、パーティクルボード等が挙げられる。熱硬化性樹脂化粧板としては、メラミン、フェノール、ジアリルフタレート、ポリエステル等の熱硬化性樹脂を化粧紙やコア紙に含浸し熱圧硬化させたもの、化粧紙にコートし常温硬化させた化粧板等が挙げられる。 Hereinafter, the present invention will be described in detail. The laminate in the present invention is a laminate in which a base material is covered with a thermosetting resin decorative board. Examples of the substrate include a single plate, a plywood, a laminated material, a medium density fiberboard (MDF), and a particle board. As the thermosetting resin decorative board, a decorative paper or core paper impregnated with thermosetting resin such as melamine, phenol, diallyl phthalate, polyester, etc. and heat-pressure cured, or a decorative board coated with decorative paper and cured at room temperature Etc.
ポリウレタン反応性ホットメルト接着剤は、ポリオール等の活性水素基含有化合物と多価イソシアネート化合物を反応させたものであり、常温で固形状の接着剤である。ポリオールとして結晶性、非晶性、液状の各種ポリオールを組み合わせたり、さらに分子量や融点を調整することにより、常温では固形状であり、加熱することにより液状となるよう調製したものである。ポリウレタン反応性ホットメルト接着剤の具体的な組成は特に限定されず、公知のものを使用することができる。 A polyurethane reactive hot melt adhesive is obtained by reacting an active hydrogen group-containing compound such as a polyol and a polyvalent isocyanate compound, and is a solid adhesive at room temperature. The polyol is prepared by combining various polyols such as crystalline, amorphous and liquid, and adjusting the molecular weight and melting point, so that it is solid at normal temperature and becomes liquid when heated. The specific composition of the polyurethane reactive hot melt adhesive is not particularly limited, and known ones can be used.
ポリウレタン反応性ホットメルト接着剤は加熱溶融状態で塗布され、被着体との接触や空気中で冷却されて固形状に戻ることによって初期接着力を発現するとともに、ウレタン反応の進行により耐熱性等の最終接着性能にも優れるものである。しかしながら、本発明においてポリウレタン反応性ホットメルト接着剤のみを用いて積層板を製造する場合、平面部を貼り合わせた直後に熱硬化性樹脂化粧板の曲げ加工を行おうとすると、熱硬化性樹脂化粧板に加えた熱がポリウレタン反応性ホットメルト接着剤層にも伝わるため、ポリウレタン反応性ホットメルト接着剤が軟化することにより基材と熱硬化性樹脂化粧板がはく離してしまう問題がある。そこで、以下の非反応性ホットメルト接着剤を併用することが必要である。 Polyurethane reactive hot melt adhesive is applied in a heated and melted state and exhibits initial adhesive force by contacting with the adherend or cooling in the air and returning to a solid state. It also has excellent final adhesion performance. However, in the case of producing a laminated board using only the polyurethane reactive hot melt adhesive in the present invention, if it is attempted to bend the thermosetting resin decorative board immediately after bonding the flat portions, the thermosetting resin makeup Since the heat applied to the plate is also transferred to the polyurethane reactive hot melt adhesive layer, there is a problem that the base material and the thermosetting resin decorative plate are peeled off when the polyurethane reactive hot melt adhesive is softened. Therefore, it is necessary to use the following non-reactive hot melt adhesive together.
非反応性ホットメルト接着剤は熱可塑性樹脂をベースとした接着剤であり、具体的にはスチレン系ブロック共重合体、ブチルゴム、粘着付与樹脂、石油樹脂、無機充填材等を配合したものである。加熱溶融して塗布され、被着体との接触や空気中で冷却されて固形状に戻ることによって接着力を発現する。反応性ホットメルト接着剤と比較して最終接着性能は劣るものの、溶融温度が高いことから、被着体の貼り合わせ直後に再加熱されても軟化しにくい性質を有する。そこで、本願発明においては、熱硬化性樹脂化粧板が基材に沿って折り曲げられる箇所から少なくとも５ｍｍ以内、好ましくは１０ｍｍ以内については、非反応性ホットメルト接着剤を用いる。 Non-reactive hot melt adhesives are adhesives based on thermoplastic resins, specifically blended with styrene block copolymers, butyl rubber, tackifying resins, petroleum resins, inorganic fillers, etc. . It is applied by heating and melting, and is brought into contact with the adherend or cooled in the air to return to a solid state, thereby exhibiting an adhesive force. Although the final adhesion performance is inferior to that of the reactive hot melt adhesive, the melting temperature is high, and therefore, it has the property that it is difficult to soften even if it is reheated immediately after the adherends are bonded. Therefore, in the present invention, a non-reactive hot melt adhesive is used at least within 5 mm, preferably within 10 mm from the location where the thermosetting resin decorative board is bent along the base material.
積層板の製造方法としては、平面部に接着剤に塗布して貼り合わせた後、側面部に接着剤を塗布して熱硬化性樹脂化粧板を基材に沿うように曲げつつ貼り合わせ、さらに必要に応じて裏面部に接着剤を塗布して熱硬化性樹脂化粧板を基材に沿うように曲げつつ貼り合わせる方法が挙げられるが、各面の貼り合わせの順序や、接着剤を塗布するタイミング、接着剤を塗布する面は特に制限されない。平面部、側面部、裏面部とは、コの字状の積層体を得る場合の基材の各面を便宜的に称したものであり、基材の形状は特に限定されない。また、熱硬化性樹脂化粧板を曲げやすくするため、曲げ加工時に加熱することが好ましい。さらに、極小の曲げ半径を得るために基材や熱硬化性樹脂化粧板を切削してもよい。 As a manufacturing method of a laminated board, after applying and bonding an adhesive to a plane part, applying an adhesive to a side part and bonding the thermosetting resin decorative board while bending along the substrate, There is a method of applying an adhesive to the back surface as needed and bonding the thermosetting resin decorative plate while bending it along the base material, but apply the bonding order of each surface and the adhesive. The timing and the surface to which the adhesive is applied are not particularly limited. A plane part, a side part, and a back part refer to each surface of the base material in the case of obtaining a U-shaped laminated body for convenience, and the shape of a base material is not specifically limited. Moreover, in order to make a thermosetting resin decorative board easy to bend, it is preferable to heat at the time of a bending process. Furthermore, in order to obtain a minimum bending radius, the base material and the thermosetting resin decorative board may be cut.
以下、本発明について実施例、比較例を挙げてより詳細に説明するが、具体例を示すものであって特にこれらに限定するものではない。 EXAMPLES Hereinafter, although an Example and a comparative example are given and demonstrated in detail about this invention, a specific example is shown and it does not specifically limit to these.
熱硬化性樹脂化粧板と基材を平貼りするため、図１に示すように熱硬化性樹脂化粧板１の基材に沿って折り曲げられる箇所から１２ｍｍ空けて、ポリウレタン反応性ホットメルト接着剤２を塗布した。また、基材４の端部から１２ｍｍの範囲に非反応性ホットメルト接着剤３を塗布した。熱硬化性樹脂化粧板１と基材４を重ね合わせ、ピンチローラーで圧締することによって、図２に示す平貼り体を得た。さらに側面部に非反応性ホットメルト接着剤３を塗布し、熱硬化性樹脂化粧板１をヒーターで加熱しつつピンチローラーで折り曲げて圧締した。裏面部も同様に折り曲げ加工を行い、図３に示すような、基材を熱硬化性樹脂化粧板でコの字状に被覆した積層板を得た。
In order to flatly bond the thermosetting resin decorative board and the base material, as shown in FIG. 1, the polyurethane reactive
本発明の製造方法によれば、基材と熱硬化性樹脂化粧板を貼り合わせてからすぐに曲げ加工を行っても浮きが発生しないため、短時間で生産することが可能であり、仕掛品が発生しない。また、平面部にはポリウレタン反応性ホットメルト接着剤が使用されるため、熱した調理器具や食器が置かれる可能性があるカウンター面は、高い耐熱性を有する。 According to the production method of the present invention, even if bending is performed immediately after the base material and the thermosetting resin decorative board are bonded together, the float does not occur. Does not occur. Moreover, since a polyurethane reactive hot melt adhesive is used for the flat portion, the counter surface on which a heated cooking utensil or tableware may be placed has high heat resistance.
