Description

本発明は壁材や床材に使用される柾目調の木質様材に関する。   The present invention relates to a wood-like material having a grid pattern used for wall materials and floor materials.

木目調の模様を有する木質様材として、異なる色調に着色された樹脂を押出成形する時に色の濃淡を生じさせ、木目調の模様が表面に表すことが知られている。（例えば、特許文献１）。   As a wood-like material having a wood grain pattern, it is known that when a resin colored in a different color tone is extruded, color shades are produced and the wood grain pattern is expressed on the surface. (For example, patent document 1).

また、ＯＳＢ（オリエンテッド・ストランド・ボード）と言われる２〜３mm程度四方の大きさの多数の木材片が並べられた状態に重ねられ、接着材により板状に塗り固められた板材が知られており、壁や間仕切として使用されている（例えば、特許文献２）。   Also known as OSB (Oriented Strand Board) is a plate material that is piled up in a state in which a large number of pieces of wood of about 2 to 3 mm in size are arranged and then solidified into a plate shape with an adhesive. It is used as a wall or partition (for example, Patent Document 2).

しかしながら、異なる色調に着色された樹脂を押出成形する時に色の濃淡を生じさせ、木目調の模様が表面表す方法では、人工的な樹脂製である感じになることは否めず、木質感が乏しかった。
また、天然材料である木材片を使用するＯＳＢ（オリエンテッド・ストランド・ボード）では、天然の木材を使用しているので、木製であることが分かるが、２〜３mm程度四方の長方形状の木材片が使用され、木材片があまり配向していないため、年輪が平行な木目として現れる柾目のような方向性のある筋（すじ）が形成されず、廃棄された木材片を固めている感じがするだけという問題があった。 However, when extruding resins colored in different tones, the method of producing shades of color and representing the surface of the woodgrain pattern cannot be denied that it is made of artificial resin, and the wood texture is poor. It was.
In addition, OSB (Oriented Strand Board), which uses a piece of wood that is a natural material, uses natural wood, so it can be seen that it is made of wood. Because the pieces are used and the wood pieces are not oriented very much, there is no directional streak that appears as a parallel grain, where the annual rings appear as parallel wood grain, and the feeling that the discarded wood pieces are solidified There was a problem just to do.

本発明の目的は、上記の問題点に鑑み、化粧材として壁材・床材・天井材等に使用される柾目調の木質様材を提供することにある。   In view of the above-described problems, an object of the present invention is to provide a wood-like material having a gray scale tone used as a decorative material for a wall material, a floor material, a ceiling material, and the like.

上記目的を達成するために、本発明の請求項１に記載の木質様材は、針葉樹からなる木質材料片と広葉樹からなる木質材料片とが混合され、重量比７０％以上が厚み１〜１０ｍｍ、長さ２０ｍｍ〜１５０ｍｍの範囲にあり、破砕されて細長い紡錘形状である多数の木質材料片からなり、重量比７０％以上の木質材料片が±１５度以内に配向された状態で積まれ、結合剤により木質材料同士が結合されていることを特徴とする。   In order to achieve the above object, the wood-like material according to claim 1 of the present invention is a mixture of a piece of wood material made of coniferous wood and a piece of wood material made of hardwood, and a weight ratio of 70% or more is 1 to 10 mm in thickness. , Consisting of a large number of pieces of wood material that are in the range of 20 mm to 150 mm in length and crushed into an elongated spindle shape, and the wood material pieces of 70% by weight or more are stacked in a state of being oriented within ± 15 degrees, The wood materials are bonded to each other by a binder.

本発明の請求項２に記載の木質様材は、辺材からなる木質材料片と心材からなる木質材料片とが混合され、重量比７０％以上が厚み１〜１０ｍｍ、長さ２０ｍｍ〜１５０ｍｍの範囲にあり、破砕されて細長い紡錘形状である多数の木質材料片からなり、重量比７０％以上の木質材料片が±１５度以内に配向された状態で積まれ、結合剤により木質材料同士が結合されていることを特徴とする。   In the wood-like material according to claim 2 of the present invention, a wood material piece made of sapwood and a wood material piece made of a heartwood are mixed, and a weight ratio of 70% or more is a thickness of 1 to 10 mm and a length of 20 mm to 150 mm. It is composed of a large number of pieces of wood material that are crushed and in the shape of an elongated spindle, and the pieces of wood material of 70% or more by weight are stacked in a state of being oriented within ± 15 degrees. It is characterized by being connected.

本発明の請求項３に記載の木質様材は、表面が透明または半透明の塗料で塗装されていることを特徴とする請求項１又は２に記載の木質様材である。   The wood-like material according to claim 3 of the present invention is the wood-like material according to claim 1 or 2, wherein the surface is painted with a transparent or translucent paint.

本発明の請求項４に記載の木質様材は、結合剤を、有色とすることを特徴とする請求項１、２又は３に記載の木質様材である。   The wood-like material according to claim 4 of the present invention is the wood-like material according to claim 1, 2 or 3, wherein the binder is colored.

木質材料片となる針葉樹としては、主に、スギ、ヒノキ、マツ、スプルース、ファー、パイン等が挙げられ、広葉樹としては、ラワン、シラカバ、アピトン、カメレレ、アスペン等が挙げられる。
心材とは、樹木の材の中心に近い部分であり、細胞壁に種々の色素が沈着して赤・黒・黄などに着色されている。辺材とは、樹木の材のうち周辺部を占める部分であり、心材に比べて淡色である。
異なる樹種の木質材料片を混合したり、辺材からなる木質材料片と心材からなる木質材料片とが混合することにより、木質材料片同士の色が異なる。そのため、木質材料片をほぼ一方向を向くように±１５度以内に配向された状態で積んで、加熱・加圧して結合剤により木質材料同士を結合することにより、長手方向に、木質材料片が柾目のような方向性のある筋（すじ）のような外観を呈する。 Examples of the conifers that serve as the wood material pieces include cedar, cypress, pine, spruce, fur, pine, and the like, and examples of the broad-leaved trees include lauan, birch, apiton, chamelere, and aspen.
The heartwood is a portion close to the center of the wood of the tree, and various pigments are deposited on the cell wall and colored red, black, yellow or the like. The sapwood is a portion that occupies the periphery of the wood, and is lighter than the heartwood.
By mixing wood material pieces of different tree species, or by mixing wood material pieces made of sapwood and wood material pieces made of heartwood, the colors of the wood material pieces differ. Therefore, the wood material pieces are stacked in a state oriented within ± 15 degrees so as to face almost one direction, and the wood material pieces are bonded in the longitudinal direction by heating and pressurizing and joining the wood materials with a binder. Has a streak-like appearance like a square.

木質材料片としては、天然木を使用しても廃棄木材を使用しても構わない。廃棄木材とは、特に限定されないが、例えば、上記樹種の丸太、間伐材等の生材料、工場や住宅建築現場で発生する端材、部材輸送後に廃棄される廃パレット材、建築解体時に発生する解体廃材等が挙げられる。   The wood material piece may be natural wood or waste wood. Waste wood is not particularly limited, but, for example, logs of the above tree species, raw materials such as thinned wood, scraps generated at factories and residential construction sites, waste pallet materials discarded after transporting materials, generated at the time of building demolition Demolition waste materials, etc. are listed.

上記原料材を木質材料片にする破砕方法としては、ハンマーミル破砕機により破砕される。ＯＳＢ（オリエンテッド・ストランド・ボード）やＷＢ（ウエファーボード）で使用される回転刃によって丸太を切削してストランドにするナイフフレーカーは、小片が薄く削られ、２〜３ｍｍ程度四方の長方形状の木材片となるから使用できない。   As a method for crushing the raw material into a wooden material piece, the material is crushed by a hammer mill crusher. A knife flaker that cuts logs with a rotary blade used in OSB (Oriented Strand Board) or WB (Wafer Board) to make a strand is thinly cut into small pieces with a rectangular shape of about 2 to 3 mm. Can not be used because it becomes a piece of wood.

本発明の木質系複合材料において、使用される木質材料片は、その比重が０．３〜０．６、その長さが２０ｍｍ〜１５０ｍｍ、その厚さ（短辺）が１ｍｍ〜１０ｍｍであることが好ましい。製造された木質系複合材料の嵩密度が０．６以上に限定されるが、その理由は、以下の通りである。
即ち、木質材料片の比重が０．３未満のもの場合、木質が腐敗しているため十分な強度が得られなかったり、成形時の圧密処理を十分に行うことができず、強度が得られない。木質材料片の比重が０．６を越えるものは、木質材料片が固く、所望する構造材としての成形が難しい。 In the wood-based composite material of the present invention, the wood material piece used has a specific gravity of 0.3 to 0.6, a length of 20 mm to 150 mm, and a thickness (short side) of 1 mm to 10 mm. Is preferred. Although the bulk density of the manufactured wood type composite material is limited to 0.6 or more, the reason is as follows.
That is, when the specific gravity of the wood material piece is less than 0.3, sufficient strength cannot be obtained due to the decay of the wood, or the compaction process cannot be sufficiently performed at the time of molding, and the strength is obtained. Absent. When the specific gravity of the wood material piece exceeds 0.6, the wood material piece is hard, and it is difficult to form it as a desired structural material.

木質材料片の厚さが１ｍｍ未満のものを用いると、構成材料片が小さくなりすぎ、多くの結合材が必要となり、また、短いのもとなりやすく強度を発現しない。一方、木質材料片の厚さが１０ｍｍを越えると、構造材料の厚さ方向への木質片の積層数が少なくなってしまい、応力伝達が十分に行えず、木質片の継ぎ目に応力集中を起こしやすく、所望な強度を得ることができない。
木質材料片の長さが２０ｍｍ未満のものを用いると、構造材として使用する場合、軸方向の強度が不十分となり、１５０ｍｍを越えるものを用いると、木質材料片を積層したとき、１本の木質材料片の積層交点が増してしまい、十分な圧密化ができない。木質材料片の長さは、完全にきっちり分離できる物ではないため、重量比で、７０％以上であり、好ましくは８０％以上が、上記長さの破砕チップが含有していれば十分効果が発揮される。 When a wood material piece having a thickness of less than 1 mm is used, the constituent material piece becomes too small, a large amount of binder is required, and a short piece tends to be formed, so that strength is not exhibited. On the other hand, if the thickness of the wood material piece exceeds 10 mm, the number of wood pieces stacked in the thickness direction of the structural material will be reduced, stress transmission will not be sufficient, and stress concentration will occur at the joint of the wood piece. It is easy and the desired strength cannot be obtained.
If a wood material piece with a length of less than 20 mm is used, when used as a structural material, the strength in the axial direction becomes insufficient. If a wood material piece with a length exceeding 150 mm is used, when the wood material pieces are laminated, The crossing points of the wood material pieces increase, and sufficient consolidation cannot be achieved. Since the length of the wood material piece is not a material that can be completely separated, the weight ratio is 70% or more, and preferably 80% or more is sufficient if the crushed chips of the above length are contained. Demonstrated.

また、木質材料片の長さと厚さとの比は、特に限定されないが、長さが厚さの１０倍以上となることが好ましい。すなわち、長さが厚さの１０倍未満であると、木質系複合材料の軸方向の強度が不十分となる恐れがある。   Moreover, the ratio between the length and the thickness of the wooden material piece is not particularly limited, but the length is preferably 10 times or more of the thickness. That is, when the length is less than 10 times the thickness, the strength in the axial direction of the wood-based composite material may be insufficient.

嵩密度が０．６未満では木質材料片の十分な結合が得られず、構造材として用いる場合、十分な強度を得ることができない恐れがある。
さらに、空隙率は、特に限定されないが、１０％以下となることが好ましい。すなわち、空隙率が１０％を越えると、木質系複合材料中の各木質材料片同士の結合が不十分となり、十分な強度を発現しなくなる恐れがある。 When the bulk density is less than 0.6, sufficient bonding of the wooden material pieces cannot be obtained, and when used as a structural material, there is a possibility that sufficient strength cannot be obtained.
Further, the porosity is not particularly limited, but is preferably 10% or less. That is, if the porosity exceeds 10%, the bonding between the wooden material pieces in the wooden composite material becomes insufficient, and there is a possibility that sufficient strength may not be exhibited.

本発明で用いられる結合剤としては、フェノール樹脂、メラミン樹脂、尿素樹脂、イソシアネート等、合板やパーティクルボードに用いられる木材工業用の接着剤が挙げられ、これらの結合剤は、単独或いは数種類を併用しても良い。
また、結合剤は、液状でも粉末状でも構わないが、に木質材料片に噴霧したり、混合した状態で付着される。 Examples of the binder used in the present invention include phenolic resin, melamine resin, urea resin, isocyanate, wood industry adhesives used for plywood and particle board, and these binders may be used alone or in combination of several kinds. You may do it.
The binder may be in the form of liquid or powder, but is attached to the wood material piece in a sprayed or mixed state.

プレス機としては、特に限定されないが、例えば、既存の木質系材料成形用の縦型プレス機や連続プレス機を垂直方向動作にしたものを用いることができる。
加熱方法としては、特に限定されないが、例えば、熱盤のように木質材料片の表面から伝熱により内部に熱を伝える方法や、蒸気噴射や高周波加熱等のように内部を直接加熱する方法が挙げられる。加熱と加圧とは、同時に行ってもよいし、加圧をした後に加熱をしてもよいし、加熱した後に加圧してもよい。 Although it does not specifically limit as a press machine, For example, what used the vertical type | mold press machine and the continuous press machine for shaping | molding the existing wood type material to a perpendicular | vertical direction operation can be used.
The heating method is not particularly limited, but for example, there is a method of transferring heat from the surface of a wooden material piece to the inside by heat transfer like a hot plate, or a method of directly heating the inside such as steam injection or high frequency heating. Can be mentioned. Heating and pressurization may be performed simultaneously, may be performed after pressurization, or may be performed after heating.

木質材料片がほぼ一方向を向くように配向された状態で積む方法として、ベルトコンベア−の上に複数の板状体が搬送方向に沿って並列に立設され、並列された板状体の上から木質材料片を投下して、配向させながら、ベルトコンベア−の上に積みながら搬送する方法や、幅方向に樋状体を並設させて、凹凸溝形状として、木質材料片が溝の内を流れることで並べる方法や、ディスクオリエンター等の公知の配向手段をフォーミング型の上方に配置し、この配向手段により配向させながら投入する方法が使用できる。   As a method of stacking in a state where the wood material pieces are oriented so as to face almost one direction, a plurality of plate-like bodies are erected in parallel along the conveying direction on the belt conveyor, and the parallel plate-like bodies are arranged. Drop the wood material piece from above, orient it, convey it while stacking it on the belt conveyor, or arrange the rod-shaped bodies side by side in the width direction to make the uneven groove shape, the wood material piece is the groove There can be used a method of arranging by flowing inside, or a method in which a known orientation means such as a disk orienter is disposed above the forming mold and thrown while being oriented by this orientation means.

さらに、本発明の木質系複合材料を製造する場合、プレス成形後、得られる木質系複合材料の寸法精度や表面性を向上させるために、切削、サンディング加工を行うことが好ましい。   Furthermore, when producing the woody composite material of the present invention, it is preferable to perform cutting and sanding in order to improve the dimensional accuracy and surface properties of the woody composite material obtained after press molding.

本発明の木質様材の表面には、透明または半透明の塗料で塗装されることが好ましい。加熱・加圧されることにより木質材料同士が結合されるが、木質様材の表面には、木質材料同士の間に若干の隙間が発生することがあり、この隙間に引っかかったり、塵が詰まったりする不具合が発生することがあるため、塗料により隙間を埋めることが考えられる。この際、塗料を有色にすると、木質様材の表面の模様を見ることができなくなるという問題が発生する。そのため、この塗料を透明または半透明とすることで、問題を解決することができる。   The surface of the woody material of the present invention is preferably painted with a transparent or translucent paint. Wood materials are joined together by heating and pressurization, but there may be slight gaps between the wood materials on the surface of the wood-like material. Therefore, it is conceivable to fill the gap with paint. At this time, if the paint is colored, there arises a problem that the pattern on the surface of the wood-like material cannot be seen. Therefore, the problem can be solved by making the paint transparent or translucent.

結合剤を、有色とすることにより、木質材料片により形成された柾目のような方向性のある筋（すじ）が明確になるため好ましい。   By making the binder colored, it is preferable because directional streaks such as squares formed by wood material pieces become clear.

本発明にかかる木質様材は、以上のように構成されているので、年輪が平行な木目として現れる柾目のような方向性のある筋（すじ）が形成され、天然的な木質感がある。よって、壁の化粧材や床材に好適に使用できる。   Since the wood-like material according to the present invention is configured as described above, directional streaks such as squares in which annual rings appear as parallel grain are formed, and there is a natural wood texture. Therefore, it can be suitably used for a wall decorative material or a flooring material.

図１は、木質様材の斜視図である。木質様材１の上下２面の長手方向（図の矢印Ｘ１方向）に対して垂直方向（図の矢印Ｚ方向）に木質材料片１１の断面積が７０％以下に圧縮され、木質材料片１１が扁平される。上下２面の木質材料片１１の平均配向角度が各木質材料片１１の繊維方向αと木質様材１の長手方向（図の矢印Ｘ１方向）とのなす角度が±１５度以内の角度で配向している。左右２面の木質材料片２２の平均配向角度が各木質材料片２２の繊維方向βと木質系複合材料１の長手方向（図の矢印Ｘ２方向）とのなす角度が±５度以内の角度で配向している。これらの配向されている木質材料片は、全てを配向することは難しいので、重量比７０％以上が上記の角度で配向している。   FIG. 1 is a perspective view of a wood-like material. The cross-sectional area of the wood material piece 11 is compressed to 70% or less in the vertical direction (the arrow Z direction in the figure) with respect to the longitudinal direction (the arrow X1 direction in the figure) of the upper and lower surfaces of the wood-like material 1. Is flattened. The average orientation angle of the wood material pieces 11 on the upper and lower surfaces is oriented so that the angle formed by the fiber direction α of each wood material piece 11 and the longitudinal direction of the wood-like material 1 (direction of arrow X1 in the figure) is within ± 15 degrees. doing. The average orientation angle of the wood material pieces 22 on the two left and right sides is within an angle of ± 5 degrees between the fiber direction β of each wood material piece 22 and the longitudinal direction of the wood-based composite material 1 (the arrow X2 direction in the figure). Oriented. Since it is difficult to orient all of these oriented wood material pieces, a weight ratio of 70% or more is oriented at the above angle.

図２は、木質様材からなる壁材の斜視図である。木質様材を化粧板として使用すると、細長い木質材料片が一方向に並んでいるため、施工後の化粧板同士の板間の継ぎ目がわかりにくくなり、当化粧板を何枚使用しても壁紙を施工したような大面積の模様が形成できる。   FIG. 2 is a perspective view of a wall material made of a wood-like material. When wood-like material is used as a decorative board, strips of wooden material are lined up in one direction, making it difficult to see the joint between the decorative panels after construction. A large-area pattern can be formed.

図３は、木質様材からなる床材の斜視図である。木質様材を床材として使用すると、木質材料を構成する木質繊維内の空隙が加圧前の40％から80％に減り、木質材料が圧密化され、成形体の硬度が高くなった。当発明により比重の低い木材が使用できなかった重歩行用の床材として、比重の低い木質材料でも使用できるようになった。表面を塗装することにより、木質材料の木目が強調され、汚れ防止ができる。また、木材が圧縮され表面硬度が高いため、重歩行用の床材として使用できる。また、木質材料片がランダムに配置されているため、隣同士の床材間の継ぎ目がわかりにくく大面積の模様が形成できる。   FIG. 3 is a perspective view of a flooring made of a wood-like material. When the wood-like material was used as a flooring material, the voids in the wood fibers constituting the wood material were reduced from 40% before pressing to 80%, the wood material was consolidated, and the hardness of the molded body increased. According to the present invention, a wood material having a low specific gravity can be used as a flooring material for heavy walking where a low specific gravity wood cannot be used. By painting the surface, the grain of the woody material is emphasized, and dirt can be prevented. Moreover, since wood is compressed and the surface hardness is high, it can be used as a flooring material for heavy walking. In addition, since the wooden material pieces are randomly arranged, the seam between the adjacent flooring materials is difficult to understand and a large area pattern can be formed.
