Description
床材、壁材、天井材等の建築内装材において、熱可塑性樹脂化粧シートを積層するときに撥水コート層と親水性コート層を塗布することにより、簡便に防水加工ができ、且つ優れた意匠とリサイクル性を併せ持つ化粧材に関する。 In building interior materials such as floor materials, wall materials, and ceiling materials, water-repellent coating layer and hydrophilic coating layer can be applied easily when waterproofing a thermoplastic resin decorative sheet, and it can be easily waterproofed. The present invention relates to a decorative material having both design and recyclability.
従来、キッチンや洗面まわり、脱衣場などの住宅内の水廻りは常に湿潤な環境にさらされ、更には水しぶきなどがかかるため、木質系床材ではフクレやシミ、カビなどが発生しやすく、木質系床材は使用しにくい環境であった。 Conventionally, the water around the house such as kitchens, washrooms, dressing rooms, etc. is always exposed to a moist environment, and it is also splashed with water, so wooden flooring tends to cause swelling, stains, mold, etc. The flooring was difficult to use.
この為、多くの住宅では水廻りにはクッションフロアーが使用されている。 For this reason, many homes use cushion floors around the water.
しかし近年の内装に対する消費者の意識の高まりや、キッチンと一体化したダイニングの登場により、水廻りにもフローリングが要求される傾向にある。 However, with increasing consumer awareness of interior decoration in recent years and the appearance of dining integrated with the kitchen, flooring tends to be required.
この為、フローリングにも耐水性が要求されるようになり、合板の上に樹脂系の化粧シートを貼着した耐水フロアーが実用化されている。 For this reason, the flooring is also required to have water resistance, and a water-resistant floor in which a resin-type decorative sheet is stuck on a plywood has been put into practical use.
しかし、上記耐水フロアーは、通常フローリングと比べ表面や木口からの吸水によるフクレ、シミは発生しにくいが、後加工によってできた溝や嵌合部分は合板が表面にでており、耐水性は十分とは言えなかった。 However, the above water-resistant floor is less likely to cause blisters and stains due to water absorption from the surface and the end of the floor compared to the normal flooring, but the grooves and fitting parts made by post-processing have plywood on the surface, and water resistance is sufficient I couldn't say that.
そこで、基材に木紛含有ポリプロピレン樹脂を使い、熱可塑性樹脂化粧シートを積層した樹脂系床材も出てきたが、嵌合部分からの水のしみ込みにより、樹脂系床材の下にある下張りの木質基材や根太を腐らせることがあった。 Therefore, resin-based flooring using wood powder-containing polypropylene resin as the base material and laminated with a thermoplastic resin decorative sheet has come out, but it is under the resin-based flooring due to water soaking from the fitting part. The wood base and joists of the underlay could be rotted.

前記嵌合部分の四方相决り部の突合せ部分に水の接触角が１００度以上になる撥水コート層を設け、且つ、
前記撥水コート層の周囲の熱可塑性樹脂シート表面に接触角が８５度以下になる親水性コート層を設ける
ことを特徴とする防水樹脂床。
A waterproof resin floor formed by laminating a thermoplastic resin decorative sheet on a resin base material formed by adding wood powder to at least a thermoplastic synthetic resin ,
The waterproof resin bed has a mating portion, the mating portion is square phase决Ri-lap shape, and provided with a return to the end of the outs phase, and,
The contact angle of water on the abutting portion of the four-way phase决Ri portion of the fitting portion only set the water repellent coating layer comprising more than 100 degrees, and,
A waterproof resin floor comprising a hydrophilic coat layer having a contact angle of 85 degrees or less on a surface of a thermoplastic resin sheet around the water repellent coat layer .
前記撥水コート層が２液硬化型シリコーン変成樹脂で有ることを特徴とする防水樹脂床。 The waterproof resin floor, wherein the water repellent coating layer is a two-component curable silicone modified resin.
前記撥水コート層と親水コート層を化粧シートのラッピング時にコートすることを特徴とする防水樹脂床。 A waterproof resin floor, wherein the water-repellent coating layer and the hydrophilic coating layer are coated when a decorative sheet is wrapped.
本発明では、木紛添加熱可塑性樹脂を相欠き嵌合をもった板状に異型成型し、化粧シートをラッピング加工により積層する時に、四方相决り部の突き合わせ部分に水の接触角が１００度以上になる撥水コート層を塗布し、更に、その周囲に接触角が８５度以下になる親水性コート層を設けることを特徴とする防水樹脂床とすることにより、通常の床材と同等の意匠性を持ち、かつ基材から耐水性をもった床材を得ることができた。 According to the present invention, when a wood-powder-added thermoplastic resin is formed into a plate shape having a phased fit, and a decorative sheet is laminated by lapping, the contact angle of water is 100 at the abutting portion of the four-way phase contact portion. Applying a water-repellent coating layer that is at least 80 ° C, and further providing a hydrophilic coating layer with a contact angle of 85 ° or less around it is equivalent to a normal flooring. It was possible to obtain a flooring material having a design property and having water resistance from the base material.
この樹脂化粧部材は、基材そのものに耐水性があるだけでなく、基材同士の嵌合部分が、任意の隙間を持たせた返しのある相欠き嵌合で密着して嵌合し、且つ、撥水コート層が水をはじき、更に、その周囲に親水性コート層が水を嵌合部より移動させる為、施工後に面としての防水性能を持たせることを可能とした。 In this resin decorative member, not only the base material itself is water resistant, but also the fitting part between the base materials is closely fitted and fitted with an inverted gap with an arbitrary gap, and The water repellent coating layer repels water, and the hydrophilic coating layer moves water from the fitting portion around the water repellent coating layer, so that it is possible to provide waterproof performance as a surface after construction.
樹脂基材の成型法に特に限定はなく、射出成形、異形成型、回転成型など任意の立体成型方法が可能であるが、長尺ものの成型に適しており、連続で生産できる、異形成型法が好適である。 There is no particular limitation on the molding method of the resin base material, and any three-dimensional molding method such as injection molding, dysmorphic molding, and rotational molding is possible. However, there is a dysmorphic molding method that is suitable for long molding and can be produced continuously. Is preferred.
異形成型法では、理論上いくらでも長尺の部材の作成が可能であり、従来、どうしても必要であった天地方向の嵌合をなくす事もでき、水が下地に浸透する主な経路である嵌合部の数を限りなく減らす事ができる。 With the dysmorphic method, it is possible to create an unlimited number of members in theory, and it is possible to eliminate the top-and-bottom fitting that was necessary in the past, and the fitting that is the main route through which water penetrates the substrate The number of parts can be reduced without limit.
樹脂基材は基材同士を嵌合させた際に、基材間に任意の隙間が出来るように調整されている。 The resin base material is adjusted so that an arbitrary gap is formed between the base materials when the base materials are fitted to each other.
基材間の隙間は、化粧シートの厚みによって嵌合が阻害されるのを防ぐと同時に、さらに嵌合の硬さを調整する。 The gap between the substrates prevents the fitting from being hindered by the thickness of the decorative sheet, and further adjusts the hardness of the fitting.
化粧シートに使われる素材は耐水性のあるものであれば特に限定は無いが、リサイクルの観点から、樹脂基材と同じ樹脂系フィルムに印刷した物であることが望ましい。 The material used for the decorative sheet is not particularly limited as long as it has water resistance, but from the viewpoint of recycling, it is desirable that the material is printed on the same resin film as the resin base material.
従来の木質系床材は床材同士を嵌合するためのサネの加工をテノーナーによる切削加工によっている。このためサネに返しを設けた嵌合形状はできなかった。 In the conventional wooden flooring, the processing of the sash for fitting the flooring materials is performed by cutting with a tenoner. For this reason, the fitting shape which provided the return | turnback in the sun was not made.
本発明の木質系樹脂化粧部材は押出し異型成形であるため、従来できなかった形の返しを設ける事ができる。 Since the wood-based resin decorative member of the present invention is an extrusion profile molding, it is possible to provide a barb having a shape that has not been possible in the past.
ホモポリプロピレン樹脂９０重量部、マレイン酸変成ポリプロピレン１０重量部に木質系添加剤を４０重量部、２軸押出し混錬機によって混合、ペレット化し木紛混合樹脂ペレットを作製した。 A wood powder mixed resin pellet was prepared by mixing and pelletizing 90 parts by weight of a homopolypropylene resin and 10 parts by weight of a maleic acid-modified polypropylene with 40 parts by weight of a wood additive using a twin-screw extrusion kneader.
この木紛混合樹脂ペレットを異形押出成形法にて断面が５ｍｍ×１５７ｍｍサイズで相欠き嵌合部分を持った床材形状に押し出した。 This wood powder mixed resin pellet was extruded into a floor material shape having a cross section of 5 mm × 157 mm and having a phased fitting portion by a profile extrusion molding method.
この樹脂基材に厚み０．２５ｍｍのオレフィン系化粧シートを１液湿気硬化型ウレタン樹脂系ホットメルト接着剤にてラッピング法により積層すると同時にまたは、後に、嵌合部分になる化粧シート上に撥水コート層として紫外線硬化型樹脂１００重量部に２液硬化型シリコーン変成樹脂（主剤フルシェードＵ−３１１：硬化剤フルシェードＵ３１１ＮＬ＝１００：１７ 東洋インキ製造株式会社製）を３０重量部添加して乾燥後の塗布量が６ｇ／ｍ２塗布したあと水銀灯にて紫外線を照射して硬化させた。 At the same time as or after laying an olefin-based decorative sheet having a thickness of 0.25 mm on this resin base material by a lapping method using a one-component moisture-curing urethane resin-based hot melt adhesive, 30 parts by weight of a two-part curable silicone modified resin (main agent full shade U-311: curing agent full shade U311NL = 100: 17 manufactured by Toyo Ink Manufacturing Co., Ltd.) is added to 100 parts by weight of an ultraviolet curable resin as a coating layer and dried. After a subsequent coating amount of 6 g / m 2 was applied, the film was cured by irradiating ultraviolet rays with a mercury lamp.
更に、撥水コート層の周辺部で基材表面上に、公知の酸化チタン系光触媒を乾燥後の塗布量が３ｇ／ｍ２塗布して乾燥させた。 Further, a known titanium oxide photocatalyst was applied at a peripheral portion of the water-repellent coating layer on the surface of the substrate, and the application amount after drying was 3 g / m 2 and dried.
次に、裏面には２ｍｍ厚のＥＶＡ系（エチレン−酢酸ビニル共重合樹脂）クッション材を積層し、防水樹脂床を得た。 Next, an EVA-based (ethylene-vinyl acetate copolymer resin) cushion material having a thickness of 2 mm was laminated on the back surface to obtain a waterproof resin floor.
