Description
【0001】[0001]
本考案は、婚礼セット、厨房器等の家具や建築材料に使用される防湿性合板に 関するものである。 The present invention relates to a moisture-proof plywood used for furniture such as wedding sets and kitchen appliances and building materials.
【0002】[0002]
わが国では、約20年前より、MDFと呼ばれるファイバーボード(木材およ びその他の植物繊維を主な原料として成形した板状製品)が利用されてきた。M DFは、表面、木口が緻密で均質、化粧性、加工性が優れている等の特徴を生か して婚礼セット、ドレッサー、テーブル、厨房器などの家具・什器、テレビ・オ ーディオ、楽器等のキャビネットや部品等の材料として市場に受け入れられ、需 要を広げて来た。その後、この材料の別の特徴である長尺物が得やすい事、品質 のばらつきが少ない事、安定供給が可能な事等を生かしたまわり縁、幅木、飾り 柱・框等の建築の造作材へと市場を広げた。 In Japan, fiberboard called MDF (a plate-shaped product formed by mainly using wood and other plant fibers) has been used for about 20 years. MDF is a furniture and fixtures such as wedding sets, dressers, tables, kitchen appliances, TVs, audio equipment, musical instruments, etc., which make use of the features that the surface and the mouth are dense and uniform, and that the cosmetics and processability are excellent. It has been accepted by the market as a material for cabinets and parts, and has expanded its demand. After that, other features of this material such as long products are easy to obtain, there is little variation in quality, stable supply is possible, and the construction work of surrounding edges, skirting boards, decorative pillars, frames, etc. Expanded the market to wood.
【0003】 今後、資源の枯渇、森林保護の考え方から素材や合板の経済的利用が困難にな る事が予想され、MDFは従来の荷重のかからない比較的穏やかな環境条件の中 で使用される木質材料にとどまらず、建築の床、壁のように、長年月に渡って荷 重に耐え、より苛酷な環境条件で使用されることが期侍されている。From the point of view of resource depletion and forest protection, it is expected that it will be difficult to use materials and plywood economically in the future, and MDF will be used under the conventional and relatively mild environmental conditions without load. Not only wood materials, but also floors and walls of buildings are expected to withstand the load for many years and be used under more severe environmental conditions.
【0004】 また、MDFは高い通気性があることから、防湿性の面でやや劣っており、防 湿性に優れたMDFの開発が望まれている。Further, since MDF has high air permeability, it is slightly inferior in terms of moisture resistance, and development of an MDF having excellent moisture resistance is desired.
【0005】[0005]
本考案は、湿度の影響を防止出来る、家具等に使用される防湿性合板であるM DFを提供する事を目的とする。 An object of the present invention is to provide an MDF, which is a moisture-proof plywood used for furniture and the like, which can prevent the influence of humidity.

【課題を解決するための手段】 本考案は上記問題点を解決するため、次の様な防湿性合板を採用した。OPP フィルム(1)の片面にエマルジョン接着剤層(2)を設け、さらにそのエマル ジョン接着剤層(2)の上にMDF(3)を設ける。また、OPPフィルム(1 )のもう一方の面には、ホットメルト接着剤層(4)を設け、さらにそのホット メルト接着剤層(4)の上にMDF(3)を設けた防湿性合板である。すなわち 、この防湿性合板は、OPPフィルム(1)の両側を、エマルジョン接着剤層( 2)とホットメルト接着剤層(4)を介在させて、2枚のMDF(3)で挟み込 む構造となっている。Means for Solving the Problems In order to solve the above problems, the present invention employs the following moisture-proof plywood. The emulsion adhesive layer (2) is provided on one surface of the OPP film (1), and the MDF (3) is provided on the emulsion adhesive layer (2). A moisture-proof plywood having a hot melt adhesive layer (4) provided on the other surface of the OPP film (1) and an MDF (3) provided on the hot melt adhesive layer (4). is there. That is, the moisture-proof plywood is a structure in which both sides of the OPP film (1) are sandwiched between two MDFs (3) with the emulsion adhesive layer (2) and the hot melt adhesive layer (4) interposed. Has become.
【0007】 MDFとは、Medium Density Fibreboardの略称で 、厚物中密度ファイバーボードのことである。JISでは、ファイバーボードを 密度範囲により、JIS−A−5905軟質繊維板(インシュミレーションボー ド、密度0.4g/cm3未満)、JIS−A−5906中質繊維板(MDF、 密度0.4g/cm3以上0.8g/cm3未満)、JIS−A−5907硬質 繊維板(ハードボード、密度0.8g/cm3)に大別している。MDF is an abbreviation for Medium Density Fiberboard, and is a thick medium-density fiberboard. According to JIS, depending on the density range, depending on the density range, JIS-A-5905 soft fiber board (insulation board, density less than 0.4 g / cm 3 ), JIS-A-5906 medium quality fiber board (MDF, density 0.4 g / Cm 3 or more and less than 0.8 g / cm 3 ) and JIS-A-5907 hard fiber board (hardboard, density 0.8 g / cm 3 ).
【0008】 なお、ファイバーボードとは、木材およびその他の植物繊維を主な原料として 成形した板状製品の総称である。ある程度の繊維束も含めてパルプ状に解繊した 繊維を水を媒体として(湿式法)もしくは空気を媒体として(乾式法)シート状 に成形し、乾燥あるいは熱圧締して製板したもので、その密度は広範囲にわたっ ている。さらに製品の強さや防音性、防火性、防虫性、および耐候性などを向上 させるため、製造工程中に接着剤その他の添加剤および塗装等の表面処理を行う 場合もある。The fiber board is a general term for plate-like products formed by mainly using wood and other plant fibers. Fibers that have been defibrated into pulp, including a certain amount of fiber bundles, are formed into sheets using water as the medium (wet method) or air as the medium (dry method), and then dried or heat-pressed to make plates. , Its density is widespread. Furthermore, in order to improve the strength, soundproofness, fireproofness, insect resistance, and weather resistance of the product, adhesives and other additives and surface treatment such as painting may be applied during the manufacturing process.
【0009】 本考案では、2軸延伸のポリプロピレンフィルムであるOPPフィルムを使用 するが、これは防湿性を特に重視するために、特にOPPフィルムが優れていた ので特定したものである。厚みは普通20〜60μmのものがよく使用される。 またOPPフィルムの中でも接着性の良好なもの(例えば、東レ(株)製S64 5等)が望ましい。In the present invention, an OPP film, which is a biaxially oriented polypropylene film, is used. This is specified because the OPP film is particularly excellent because the moisture resistance is particularly important. A thickness of 20 to 60 μm is often used. Among OPP films, those having good adhesiveness (for example, S645 manufactured by Toray Industries, Inc.) are desirable.
【0010】 エマルジョン接着剤層は、エマルジョン接着剤が硬化したものである。エマル ジョン接着剤は、合成樹脂の微小粒子が水に浮遊分散している接着剤である。単 量体を乳化剤や保護コロイドの存在化で水の中で乳化重合してつくるものが多い が、合成樹脂を溶剤または可塑剤に溶解させて、それを乳化するものなども一部 用いられている。エマルジョン接着剤の長所は、媒体が水であるために衛生上、 火災上の危険がなく、水で希釈、洗浄が可能であり、しかも乾燥後は耐水性の皮 膜をつくることができることである。また高濃度、低粘度のものができ、糸をひ かないためにローラー塗布、はけ塗り、スプレー塗布もできる。エマルジョン接 着剤としては、酢酸ビニル樹脂系エマルジョン、アクリル共重合樹脂系エマルジ ョン、ウレタン変性ビニル樹脂系エマルジョン等があげられる。The emulsion adhesive layer is a cured emulsion adhesive. The emulsion adhesive is an adhesive in which fine particles of synthetic resin are suspended and dispersed in water. Many are produced by emulsion polymerization of monomers in water in the presence of emulsifiers and protective colloids, but some are also used, such as those in which a synthetic resin is dissolved in a solvent or a plasticizer to emulsify it. There is. The advantage of emulsion adhesives is that they are water, and therefore there is no danger of hygiene and fire, they can be diluted and washed with water, and after drying they can form a water-resistant skin. . In addition, a high-concentration, low-viscosity product can be obtained, and roller coating, brush coating, and spray coating can be performed because the yarn is not pulled. Examples of emulsion adhesives include vinyl acetate resin emulsions, acrylic copolymer resin emulsions, urethane-modified vinyl resin emulsions, and the like.
【0011】 ホットメルト接着剤層は、熱溶融した後、冷えて固まったホットメルト接着剤 でできている。ホットメルト接着剤は、加熱、溶融状態で接着する固形の接着剤 である。ホットメルト接着剤が熱可塑性の場合には、冷却するとただちに固化す るので、きわめて短時間に接着できる。その外観は板状、ひも状、チップ、粉末 など各種の形状のものがある。ホットメルト接着剤としては、EVA系ホットメ ルト接着剤やポリオレフィン系ホットメルト接着剤やポリアミド系ホットメルト 接着剤やポリエステル系ホットメルト接着剤やアクリル樹脂系ホットメルト接着 剤やポリウレタン系ホットメルト接着剤等があげられる。The hot melt adhesive layer is made of a hot melt adhesive which is melted by heat and then cooled and solidified. A hot melt adhesive is a solid adhesive that adheres when heated and melted. If the hot-melt adhesive is thermoplastic, it solidifies immediately upon cooling, so it can bond in an extremely short time. There are various shapes such as plate, string, chip, and powder. Hot melt adhesives include EVA hot melt adhesives, polyolefin hot melt adhesives, polyamide hot melt adhesives, polyester hot melt adhesives, acrylic resin hot melt adhesives and polyurethane hot melt adhesives. Can be given.
