Description
本発明は、耐水性及び寸法安定性を強化しながらも、環境に優しく、クッション性及び遮音性に優れ、軽量化を実現できる新たなボード及びその製造方法、並びにそのボードを用いた室内内装材に関する。 The present invention is a new board and a manufacturing method thereof that are environmentally friendly, have excellent cushioning and sound insulation properties, and can realize weight reduction while enhancing water resistance and dimensional stability, and an interior interior material using the board. Regarding.
通常、室内床材、壁材のような室内内装材の用途に使用される硬質のボード資材としては、合板、HDF(High Density Fiberboard)、MDF(Medium Density Fiberboard)、無機物ボード、繊維ボードなどがある。それぞれのボードは欠点を有しており、合板、HDF、MDFのような木質系ボードの場合、耐水性が悪く、無機物ボードの場合、比重が高いため軽量化する必要がある。繊維ボードの場合、寸法補強繊維が高分子バインダーと一定の重量で混合されているが、この場合、補強繊維のバリ(bur)により、一定の大きさに加工されたボードを締結できる溝の加工が難しいという問題があった。 Hardboard materials usually used for interior interior materials such as interior flooring and wall materials include plywood, HDF (High Density Fiberboard), MDF (Medium Density Fiberboard), inorganic boards, and fiberboards. is there. Each board has drawbacks, and in the case of wood-based boards such as plywood, HDF, and MDF, water resistance is poor, and in the case of inorganic boards, the specific gravity is high, so it is necessary to reduce the weight. In the case of fiber boards, dimensional reinforcing fibers are mixed with a polymer binder at a constant weight, but in this case, the burrs of the reinforcing fibers are used to process grooves that can fasten boards processed to a certain size. There was a problem that it was difficult.
前記のような各ボードの問題点を解決するために、大韓民国公開特許公報第10−2008−0092588号は、ケナフ(Kenaf)ボードの両面にHDF又はMDFを接着したり、HDF又はMDFの両面にケナフボードを接着したりした後、プレス成形して形成された複合基材上に、表面層及び表面処理層を順次形成した床材を提供することによって、耐水性、寸法安定性などの基本物性を改善するようにした床材を開示している。 In order to solve the problems of each board as described above, the Republic of Korea Patent Publication No. 10-2008-0092588 has HDF or MDF adhered to both sides of the Kenaf board, or both sides of the HDF or MDF. By providing a flooring material in which a surface layer and a surface treatment layer are sequentially formed on a composite base material formed by press molding after adhering a kenaf board, basic physical properties such as water resistance and dimensional stability are provided. We disclose flooring materials that are designed to improve.
しかし、先行技術に開示された複合基材は、既存のHDF又はMDFに比べて寸法安定性が一部改善されたかも知れないが、HDF又はMDFを含むことにより、耐水性及び寸法安定性の問題が依然として存在する。また、複合基材が硬質のボードのみで構成されているため、床材のクッション性及び軽量性が不十分であるという問題がある。 However, the composite substrate disclosed in the prior art may have some improvements in dimensional stability as compared with the existing HDF or MDF, but by including HDF or MDF, the water resistance and dimensional stability are improved. The problem still exists. Further, since the composite base material is composed of only a hard board, there is a problem that the cushioning property and the light weight of the floor material are insufficient.
また、最近、生活の質が向上するにつれて、健康はもとより、環境に優しい製品への関心が高まっており、マンションの層間の騒音問題が社会的問題として台頭している実情で層間の騒音を最小化できる室内内装材が要求される。その一例として、住居生活と密接な関係のある床材及び壁材などのような室内内装材は、次第に環境への配慮及び遮音性能を付与できる材質を使用している趨勢である。 In addition, as the quality of life has improved recently, interest in environmentally friendly products as well as health has increased, and the noise problem between layers of condominiums has emerged as a social problem to minimize the noise between layers. Interior interior materials that can be converted are required. As an example, indoor interior materials such as flooring materials and wall materials, which are closely related to living life, tend to use materials that can gradually give consideration to the environment and sound insulation performance.
したがって、既存の木質系ボードの欠点を解決するために、耐水性及び寸法安定性を強化しながらも、環境に優しく、クッション性及び遮音性に優れ、軽量化を実現できる新たなボードの開発、及びそれを用いた室内内装材の開発が切実に要求されている。 Therefore, in order to solve the drawbacks of existing wood-based boards, we have developed a new board that is environmentally friendly, has excellent cushioning and sound insulation, and can achieve weight reduction while enhancing water resistance and dimensional stability. And the development of interior interior materials using it is urgently required.
上記のような問題点を解決するために、本発明は、耐水性及び寸法安定性を強化しながらも、環境に優しく、クッション性及び遮音性に優れ、軽量化を実現できる新たなボード及びその製造方法、並びにそのボードを用いた室内内装材を提供することを目的とする。 In order to solve the above-mentioned problems, the present invention is a new board which is environmentally friendly, has excellent cushioning and sound insulation, and can realize weight reduction while enhancing water resistance and dimensional stability. It is an object of the present invention to provide a manufacturing method and an interior interior material using the board.
上記目的を達成するために、本発明は、第1寸法補強層と;前記第1寸法補強層上に形成されたコア層と;前記コア層上に形成された第2寸法補強層と;を含む室内内装材用ボードを提供する。 In order to achieve the above object, the present invention comprises a first dimension reinforcing layer; a core layer formed on the first dimension reinforcing layer; and a second dimension reinforcing layer formed on the core layer; Provide boards for interior interior materials, including.
また、本発明は、発泡フォームを準備するステップと;前記発泡フォームの下部及び上部に繊維不織布を位置させた後、熱ラミネートするステップと;を含む室内内装材用ボードの製造方法を提供する。 The present invention also provides a method for manufacturing a board for an interior interior material, which comprises a step of preparing a foam foam; a step of locating a fibrous nonwoven fabric on the lower and upper portions of the foam foam and then heat laminating the foam.
また、本発明は、前記室内内装材用ボード上に表面材を付着して形成された室内内装材を提供する。 The present invention also provides an interior interior material formed by adhering a surface material onto the interior interior material board.
本発明の室内内装材用ボードは、コア層として発泡フォームを用いているので、クッション性及び遮音性に優れ、衝撃吸収が可能であり、軽量化された室内内装材用ボードを提供できるという効果がある。 Since the board for interior interior materials of the present invention uses foam as the core layer, it has excellent cushioning and sound insulation properties, can absorb shocks, and has the effect of providing a lightweight board for interior interior materials. There is.
また、本発明の室内内装材用ボードは、コア層として発泡フォームを、第1寸法補強層及び第2寸法補強層として繊維不織布を用い、これらを熱ラミネートして、コア層を中心に下部及び上部に第1寸法補強層及び第2寸法補強層がそれぞれ形成された室内内装材用ボードを製造することによって、耐水性及び寸法安定性に優れた室内内装材用ボードを提供できるという効果がある。 Further, in the board for interior interior material of the present invention, foam foam is used as a core layer, and a fibrous non-woven fabric is used as a first dimension reinforcing layer and a second dimension reinforcing layer, and these are thermally laminated to form a lower portion centering on the core layer. By manufacturing a board for an interior interior material in which a first dimension reinforcing layer and a second dimension reinforcing layer are formed respectively on the upper portion, there is an effect that a board for an interior interior material having excellent water resistance and dimensional stability can be provided. ..
また、本発明の室内内装材用ボードは、第1寸法補強層及び第2寸法補強層を形成するための繊維不織布内の補強繊維として天然繊維を使用し、合成樹脂繊維としてポリオレフィン系樹脂を使用することによって、環境に優しい室内内装材用ボードを提供できるという効果がある。 Further, the board for interior interior material of the present invention uses natural fibers as reinforcing fibers in the fiber non-woven fabric for forming the first dimension reinforcing layer and the second dimension reinforcing layer, and uses a polyolefin resin as the synthetic resin fiber. By doing so, there is an effect that an environment-friendly board for interior interior materials can be provided.
また、本発明の室内内装材用ボードは、ソフトなコア層を中心にハードな第1寸法補強層及び第2寸法補強層が対称的に位置して、従来の繊維ボードが実現できなかったさねはぎ(Tongue & groove)又はクリック構造の形成が可能であるという効果がある。 Further, in the board for interior interior material of the present invention, the hard first dimension reinforcing layer and the second dimension reinforcing layer are symmetrically located around the soft core layer, and the conventional fiber board cannot be realized. It has the effect of being able to form a symmetry & groove or click structure.
以下では、本発明を添付の図面と共に具体的に説明する。 Hereinafter, the present invention will be specifically described together with the accompanying drawings.
図1に示したように、本発明の室内内装材用ボード1は、第1寸法補強層10と;前記第1寸法補強層10上に形成されたコア層30と;前記コア層30上に形成された第2寸法補強層50と;を含む。 As shown in FIG. 1, the board 1 for an interior interior material of the present invention has a first dimension reinforcing layer 10; a core layer 30 formed on the first dimension reinforcing layer 10; and a core layer 30 formed on the first dimension reinforcing layer 10. Includes the formed second dimension reinforcing layer 50 and;
本発明において前記第1寸法補強層10及び第2寸法補強層50は、繊維不織布を熱圧着して形成されたボードの形態であって、室内内装材用ボード1が耐水性及び寸法安定性を確保できるようにする役割を果たす。 In the present invention, the first dimension reinforcing layer 10 and the second dimension reinforcing layer 50 are in the form of a board formed by thermocompression bonding a fibrous non-woven fabric, and the board 1 for an interior interior material has water resistance and dimensional stability. It plays a role in ensuring that it can be secured.
前記繊維不織布は、合成樹脂繊維及び補強繊維を含むように製造することで、コア層30との熱圧着時に、繊維不織布内の合成樹脂繊維の溶融によって、別途の接着剤なしにもコア層との接着が可能である。前記繊維不織布内の合成樹脂繊維と補強繊維との重量比は、5:5〜7:3であることが好ましい。補強繊維の重量比が5を超える場合、引張強度や曲げ強度は高くなるが、相対的に合成樹脂繊維の重量が低くなるため、不織布が良好に形成されず、形成された不織布が脆い(brittle)ため、好ましくなく、3未満の場合、引張強度や曲げ強度が弱いため、好ましくない。また、合成樹脂繊維の重量比が7を超える場合、多孔性素材である不織布を製造する意味がなくなり、5未満の場合、不織布が良好に形成されないため、繊維不織布内の合成樹脂繊維と補強繊維との重量比は、5:5〜7:3であることが好ましい。 By manufacturing the fibrous nonwoven fabric so as to contain synthetic resin fibers and reinforcing fibers, the synthetic resin fibers in the fibrous nonwoven fabric are melted during thermal pressure bonding with the core layer 30 to form a core layer without a separate adhesive. Can be bonded. The weight ratio of the synthetic resin fiber to the reinforcing fiber in the fibrous nonwoven fabric is preferably 5: 5 to 7: 3. When the weight ratio of the reinforcing fibers exceeds 5, the tensile strength and bending strength are high, but the weight of the synthetic resin fibers is relatively low, so that the non-woven fabric is not formed well and the formed non-woven fabric is brittle. ) Therefore, it is not preferable, and if it is less than 3, the tensile strength and bending strength are weak, which is not preferable. Further, when the weight ratio of the synthetic resin fiber exceeds 7, there is no point in producing the non-woven fabric which is a porous material, and when it is less than 5, the non-woven fabric is not formed well, so that the synthetic resin fiber and the reinforcing fiber in the fibrous non-woven fabric are not formed. The weight ratio with and is preferably 5: 5 to 7: 3.
前記合成樹脂繊維は、熱可塑性樹脂であって、比較的有害物質の放出のない環境に優しい素材であるポリオレフィン系繊維を用いることができる。 As the synthetic resin fiber, a polyolefin-based fiber which is a thermoplastic resin and is an environment-friendly material that does not release relatively harmful substances can be used.
前記ポリオレフィン系繊維は、ポリエチレン繊維、ポリプロピレン繊維、またはポリエチレンテレフタレート繊維を用いることが好ましい。前記ポリオレフィン系繊維は、単一樹脂の繊維であってもよく、またはコア−シェル構造の繊維であって、コアをなす繊維とシェルをなすコーティング樹脂を同種又は異種の樹脂を用いて製造したものであってもよい。 As the polyolefin fiber, it is preferable to use polyethylene fiber, polypropylene fiber, or polyethylene terephthalate fiber. The polyolefin-based fiber may be a single resin fiber, or is a fiber having a core-shell structure, in which the core fiber and the shell coating resin are produced by using the same or different resins. It may be.
前記補強繊維として、ガラス繊維、炭素繊維(アラミド繊維)、及び天然繊維からなる群から選択された1つまたは2つ以上を混合して使用することができる。好ましくは、環境に優しく、寸法変化率が小さい天然繊維を単独で用いることが好ましい。 As the reinforcing fiber, one or two or more selected from the group consisting of glass fiber, carbon fiber (aramid fiber), and natural fiber can be mixed and used.

前記発泡フォームの硬度は、ショアD(Shore D type)硬度で65〜85であることが、クッション性を発現するのに好ましい。65未満の場合、ダブルベルトプレス圧着工程上、フォームが過度に押されることがあり、85を超える場合は、クッション性が弱くなるため、前記範囲内の硬度を有することが好ましい。 The hardness of the foam foam is preferably 65 to 85 in Shore D type hardness in order to exhibit cushioning properties. If it is less than 65, the foam may be pressed excessively in the double belt press crimping process, and if it exceeds 85, the cushioning property is weakened. Therefore, it is preferable to have a hardness within the above range.
前記発泡フォームの厚さは3〜7mmであってもよく、この発泡フォームを寸法補強層と積層後に熱ラミネートして形成されたコア層30の厚さは、発泡フォームの初期の厚さに対して約40〜50%圧着されて、1.5〜4.5mmであり得る。 The thickness of the foam may be 3 to 7 mm, and the thickness of the core layer 30 formed by laminating the foam with the dimensional reinforcement layer and then heat-laminating the foam is with respect to the initial thickness of the foam.

本発明は、前記の室内内装材用ボードの製造方法に関し、具体的には、発泡フォームを準備するステップと;前記発泡フォームの下部及び上部に繊維不織布を位置させた後、熱ラミネートするステップと;を含む室内内装材用ボードの製造方法に関する。 The present invention relates to the method for manufacturing a board for an interior interior material, specifically, a step of preparing a foam foam; a step of locating a fibrous nonwoven fabric on the lower and upper portions of the foam foam, and then heat laminating. The present invention relates to a method for manufacturing a board for interior interior materials including.
本発明の製造方法に用いられた発泡フォーム及び繊維不織布に関する説明は、前記で記載したので、重複記載は省略する。 Since the description of the foamed foam and the fibrous nonwoven fabric used in the production method of the present invention has been described above, duplicate description will be omitted.
また、前記熱ラミネートするステップにおいて、熱ラミネートの温度条件は200〜250℃であり得る。200℃未満では、繊維不織布内の合成樹脂繊維の溶融が良好に行われないため、発泡フォームとの熱ラミネートが容易ではなく、250℃を超える場合には、合成樹脂の溶融が過度に行われてしまい、ボードの厚さを制御することが難しいため、前記温度範囲内で熱ラミネートを行うことが好ましい。 Further, in the step of heat laminating, the temperature condition of the heat laminating can be 200 to 250 ° C. If the temperature is lower than 200 ° C, the synthetic resin fibers in the fibrous nonwoven fabric are not melted well, so that thermal lamination with the foam is not easy. If the temperature exceeds 250 ° C, the synthetic resin is excessively melted. Since it is difficult to control the thickness of the board, it is preferable to perform thermal laminating within the above temperature range.
本発明において、前記熱ラミネートするステップは、ダブルベルトプレス(Double belt press)装置を用いることができる(図5参照)。 In the present invention, a double belt press device can be used for the heat laminating step (see FIG. 5).
または、前記熱ラミネートするステップにおいて、前記発泡フォームと繊維不織布との間にホットメルトフィルムをさらに位置させた後に熱ラミネートすることもできる。これは、発泡フォームと繊維不織布との間に加熱圧着のみでは接着力が弱い場合、すなわち、一例として、発泡フォームの合成樹脂と繊維不織布内の合成樹脂繊維の材質の差によって接着力が弱い場合、ホットメルトフィルムを媒介として熱ラミネートすることができる。または、選択的に、ホットメルトフィルムの代わりに、発泡フォームの上部及び下部に接着剤を塗布した後、繊維不織布を付着させて熱ラミネートすることもできる。 Alternatively, in the heat laminating step, the hot melt film may be further positioned between the foam and the fibrous nonwoven fabric, and then heat laminating may be performed. This is the case where the adhesive strength is weak between the foamed foam and the fibrous nonwoven fabric only by heat-bonding, that is, for example, the adhesive strength is weak due to the difference in the material of the synthetic resin of the foamed foam and the synthetic resin fiber in the fibrous nonwoven fabric. , Can be heat-laminated via a hot melt film. Alternatively, optionally, instead of the hot melt film, an adhesive may be applied to the upper and lower parts of the foam, and then a fibrous nonwoven fabric may be attached and heat-laminated.
本発明の室内内装材用ボードの製造方法は、前記熱ラミネートステップの後に側面にさねはぎを形成するステップをさらに含むことによって、複数のボード間の締結を容易にすることができる(図6参照)。 The method for manufacturing a board for an interior interior material of the present invention can facilitate fastening between a plurality of boards by further including a step of forming a tongue on the side surface after the heat laminating step (FIG. 6). reference).
または、さねはぎの代わりにクリック構造を形成するステップをさらに含むことができる(図7参照)。 Alternatively, it may further include the step of forming a click structure instead of a tongue (see FIG. 7).
前記さねはぎを形成するステップ又はクリック構造を形成するステップは、好ましくは、室内内装材用ボードの上部に表面材を付着した状態でさねはぎ構造又はクリック構造を形成することが、形成の容易性及び工程経済上、好ましい。 The step of forming the tongue or the click structure is preferably formed by forming the tongue structure or the click structure with the surface material attached to the upper part of the board for the interior interior material. It is preferable in terms of ease and process economy.
本発明は、前記室内内装材用ボードの製造方法は、選択的に、発泡フォームと繊維不織布とを熱ラミネートして室内内装材用ボードを製造する方法の代わりに、繊維不織布を熱圧着して成形した繊維ボードと発泡フォームとを接着剤で接着して製造することもできる。この場合、繊維ボードの比重が0.4〜0.7であるものを使用することが好ましい。一方、このような方法により製造された室内内装材用ボードの比重が約0.5〜0.7となるように発泡フォームの厚さを調節することが好ましい。 In the present invention, in the method for manufacturing a board for interior interior materials, instead of the method for manufacturing a board for interior interior materials by selectively heat-laminating foam foam and fibrous nonwoven fabric, the fibrous nonwoven fabric is heat-bonded. It can also be manufactured by adhering a molded fiber board and foam foam with an adhesive. In this case, it is preferable to use a fiber board having a specific gravity of 0.4 to 0.7. On the other hand, it is preferable to adjust the thickness of the foam so that the specific gravity of the board for interior interior material produced by such a method is about 0.5 to 0.7.
本発明は、前記の室内内装材用ボードを用いた室内内装材に関し、前記室内内装材用ボード1上に表面材3を付着して形成された室内内装材Aに関する(図3及び図4参照)。 The present invention relates to an interior interior material using the interior interior material board, and relates to an interior interior material A formed by adhering a surface material 3 on the interior interior material board 1 (see FIGS. 3 and 4). ).
本発明の室内内装材Aは、床材または壁材であってもよい。 The interior interior material A of the present invention may be a floor material or a wall material.
前記表面材3は、ポリエチレン、ポリプロピレン、ポリ塩化ビニルのような熱可塑性樹脂系シート、HPM(high pressure melamine)のような熱硬化性樹脂系シート、経木又は原木のような木質系シート、または無機質系シートであってもよい。 The surface material 3 is a thermoplastic resin-based sheet such as polyethylene, polypropylene, or polyvinyl chloride, a thermosetting resin-based sheet such as HPM (high pressure melamine), a wood-based sheet such as warp wood or raw wood, or an inorganic material. It may be a system sheet.
前記熱可塑性樹脂系シートは、非発泡シートまたは発泡シートであってもよい。 The thermoplastic resin-based sheet may be a non-foamed sheet or a foamed sheet.
前記表面材3の厚さは、0.2〜2mmであってもよい。 The thickness of the surface material 3 may be 0.2 to 2 mm.
前記表面材3内には、印刷パターンが形成されたフィルム又は紙などが貼り合わされているので、審美感に優れた外観及びデザイン効果を付与することができる。 Since a film or paper on which a print pattern is formed is bonded to the surface material 3, it is possible to impart an aesthetically pleasing appearance and design effect.
前記表面材3を室内内装材用ボード1上に付着するために使用される接着剤は、表面材の種類に応じて異なり得、表面材として熱可塑性樹脂系シートを用いる場合には、オレフィン系ホットメルト、反応性ポリウレタン(Reactive polyurethane)、EVAホットメルトなどの接着剤を使用することができ、HPM(high pressure melamine)のような熱硬化性樹脂系シートを用いる場合には、エポキシ、ポリウレタン系またはメラミン系接着剤を使用することができ、経木又は原木のような木質系シートを用いる場合には、PVAc系接着剤を使用することができる。 The adhesive used to attach the surface material 3 onto the indoor interior material board 1 may differ depending on the type of the surface material, and when a thermoplastic resin-based sheet is used as the surface material, it is olefin-based. Adhesives such as hot melt, reactive polyurethane, EVA hot melt can be used, and when a thermosetting resin sheet such as HPM (high pressure melamine) is used, epoxy or polyurethane is used. Alternatively, a melamine-based adhesive can be used, and when a wood-based sheet such as warp wood or raw wood is used, a PVAc-based adhesive can be used.
選択的に、表面材3との接着力を高めるために、接着剤を塗布する前に室内内装材用ボード1の表面をサンディング(sanding)加工することができる。 Optionally, the surface of the interior interior material board 1 can be sanded before the adhesive is applied in order to increase the adhesive force with the surface material 3.
また、室内内装材用ボード1上に接着剤を塗布して第3接着層2の形成後に表面材3を付着する場合、ボード1の上部に付着された表面材3により、内装材の全体的な曲げバランスが合わないことがあるため、この場合、ボード1の下部に別途にシートを付着してバランス層(図示せず)を形成することによって、全体的な曲げバランスを維持できるようにすることができる。また、前記バランス層の厚さは、前記表面材3と同一又は類似の厚さの範囲で形成することが好ましい。 Further, when an adhesive is applied onto the interior interior material board 1 to attach the surface material 3 after the formation of the third adhesive layer 2, the surface material 3 attached to the upper part of the board 1 causes the entire interior material to adhere. In this case, a sheet is separately attached to the lower part of the board 1 to form a balance layer (not shown) so that the overall bending balance can be maintained. be able to. Further, the thickness of the balance layer is preferably formed in the range of the same or similar thickness as the surface material 3.
前記バランス層は、前記第1寸法補強層10に含まれた合成樹脂と同じ材質の熱可塑性樹脂を使用することができ、この場合、前記バランス層とボード1の第1寸法補強層10との接着力が向上して、室内内装材Aの耐久性を向上させることができる。 As the balance layer, a thermoplastic resin of the same material as the synthetic resin contained in the first dimension reinforcing layer 10 can be used. In this case, the balance layer and the first dimension reinforcing layer 10 of the board 1 are combined. The adhesive strength is improved, and the durability of the interior interior material A can be improved.
