Description

本発明は、床材に関し、より詳しくは、床材の自然な表面の質感を向上させるためのハンドクラフト（Hand-Craft、手工業）効果が容易に得られ、凹み、引っかき、及び変色等を防ぐことができる床材に関する。   The present invention relates to a flooring material, and more specifically, a hand-craft effect for improving the natural surface texture of the flooring material is easily obtained, and dents, scratches, discoloration, and the like are prevented. It can be related to flooring.

一般的に、建築物の室内床に施工されたコンクリート面等を覆い、装飾し、高級な室内雰囲気を演出するとともに、全体的に自然な木の質感を得るために床材を施工している。   In general, the concrete surface, etc. constructed on the indoor floor of the building is covered and decorated to produce a high-quality indoor atmosphere, and flooring is applied to obtain an overall natural wood texture. .

周知のとおり、合板製造技術の発達につれて、原木の活用度を高め、物性に優れた合板等が多く提供されているが、合板は、原木を加工するにあたって、原木から角材や板材を直接切断せず、原木を丸く削り、薄く形成された木の薄板を裁断し、その木目が互いに垂直方向に配置されるように積層し、接着剤等で薄板を互いに固着し、一定の厚さを有する板状体に成形して製造される。   As is well known, with the development of plywood manufacturing technology, the utilization of raw wood has been improved and many plywoods with excellent physical properties have been provided. First, the raw wood is cut into rounds, the thin wooden plates are cut, laminated so that the grain is arranged in the vertical direction, and the thin plates are fixed to each other with an adhesive, etc., and have a certain thickness It is manufactured by molding into a body.

このため、合板は、木目を有する木の板材に比べて、一定の木目の方向を有せず、歪み等が殆どなく、全ての方向への耐靭性等が向上するという長所を有する。しかしながら、このような方法で加工された合板は、その加工特性上、木本来の木目等の模様がなく、装飾性が低下するという問題点があった。   For this reason, the plywood has advantages in that it does not have a fixed grain direction, has almost no distortion and the like, and has improved toughness in all directions. However, the plywood processed by such a method has a problem that there is no pattern such as a natural grain of the tree due to its processing characteristics, and the decorativeness is deteriorated.

したがって、このような合板が床等の床材やその他の建築資材用に用いられる場合、これをさらにスライスドベニヤ等で表面を装飾し、その表面を樹脂塗料でコート処理することにより、耐水性及び引っかき現象に対する耐性を与えている。   Therefore, when such plywood is used for flooring such as floors and other building materials, the surface is further decorated with sliced veneer and the surface is coated with a resin paint, thereby providing water resistance. And resistance to scratching.

このような形態の室内床材を製造する一例として、合板の上面にスライスドベニヤの単板をヨウ素樹脂で接着して、床板材を製造する方法があるが、製造原価の上昇をもたらし、耐水性及び耐熱性が極めて脆弱であるという短所があった。   As an example of manufacturing an indoor floor material of such a form, there is a method of manufacturing a floor board material by adhering a sliced veneer veneer with an iodine resin to the upper surface of a plywood. There is a disadvantage that the property and heat resistance are extremely fragile.

また、木を表面に用いる床材は、現実性を確保するために、ハンドクラフト効果が求められ、このようなハンドクラフト効果は、一々手作業で進行するため、生産性を確保し難かった。特に、前記ハンドクラフト効果は、一般に用いられる０．５ｍｍのスライスドベニヤでは得られ難く、少なくとも２ｍｍ以上の原木を用いなければならないので、製造原価の上昇要因となる問題点があった。   In addition, floor materials using wood as a surface are required to have a handcraft effect in order to ensure the reality, and such a handcraft effect proceeds by hand, so it is difficult to ensure productivity. In particular, the handcraft effect is difficult to obtain with a commonly used 0.5 mm sliced veneer, and at least 2 mm or more of raw wood must be used, which causes a problem of increasing manufacturing costs.

本発明は、上記問題点に鑑みなされたものであり、その目的は、ベース層の上面に積層される表面層を、木の代わりにＰＬＡ（Poly Lactic Acid）樹脂を用いて形成することにより、親環境性を確保することができ、表面層の生産時、上面にエンボスロールを用いた屈曲パターンを適用して手工芸的な表面の質感が容易に得られ、木に比べて、凹み、引っかき、及び変色等を防ぐようにした床材を提供することにある。   The present invention has been made in view of the above problems, and its purpose is to form a surface layer laminated on the upper surface of the base layer by using PLA (Poly Lactic Acid) resin instead of wood. It is possible to ensure environmental friendliness, and during the production of the surface layer, the texture of the handicraft surface can be easily obtained by applying a bending pattern using an embossing roll on the upper surface. Another object is to provide a flooring that prevents discoloration and the like.

上述した目的を達成するために、本発明は、建築構造物の床に施工される床材であって、ＭＤＦ、ＨＤＦまたは合板のいずれか一つからなるベース層と、前記ベース層の上面に補強層、印刷層、透明層が順次積層され、これらの層の一つ以上がＰＬＡ樹脂からなる表面層と、を備え、前記表面層の上面には、手工芸的な表面の質感を表現するための屈曲パターンが形成されたことを特徴とする。   In order to achieve the above-described object, the present invention provides a flooring material to be constructed on a floor of a building structure, comprising a base layer made of any one of MDF, HDF or plywood, and an upper surface of the base layer. A reinforcing layer, a printed layer, and a transparent layer are sequentially laminated, and at least one of these layers is a surface layer made of PLA resin, and the upper surface of the surface layer expresses a handcrafted surface texture For this reason, a bent pattern is formed.

前記表面層の上面に屈曲パターンを形成し、手工芸的な表面の質感を表現したことを特徴とする。   A bent pattern is formed on the upper surface of the surface layer to express a hand-crafted surface texture.

この場合、前記屈曲パターンは、モータの動力を伝達されて回転する一対のエンボスローラ間に前記表面層を通過させる加圧工程によって形成されたものであることを特徴とする。   In this case, the bending pattern is formed by a pressurizing step of allowing the surface layer to pass between a pair of embossing rollers that are rotated by transmitting the power of the motor.

また、前記一対のエンボスローラの少なくとも一つの外周縁には、前記表面層の一面を加圧して屈曲パターンを形成するための所定形状の突出部が設けられたことを特徴とする。   Further, at least one outer peripheral edge of the pair of embossing rollers is provided with a protruding portion having a predetermined shape for pressurizing one surface of the surface layer to form a bent pattern.

また、前記表面層は、熱硬化性メラミン樹脂の接着層を介して前記ベース層の上面に積層されたことを特徴とする。   The surface layer is laminated on the upper surface of the base layer through an adhesive layer of a thermosetting melamine resin.

また、前記表面層の上面には、ＵＶコート層が積層されたことを特徴とする。   Further, a UV coat layer is laminated on the upper surface of the surface layer.

また、前記ベース層の下部には、上・下側の全般的な撓みバランスを取るための基材層がさらに設けられたことを特徴とする。   The base layer may further include a base material layer for balancing the upper and lower deflections.

本発明によれば、ベース層の上面に積層される表面層を、木の代わりにＰＬＡ樹脂を用いて形成することにより、親環境性を確保するとともに、製造原価を低くし、表面層の生産時、上面にエンボスロールを用いた屈曲パターンを適用して手工芸的な表面の質感が容易に得られ、これにより、木に比べて、凹み、引っかき、及び変色等を防ぐ等の優れた表面物性を確保することができる。   According to the present invention, the surface layer laminated on the upper surface of the base layer is formed by using PLA resin instead of wood, thereby ensuring environmental friendliness and lowering the manufacturing cost and producing the surface layer. Sometimes, the surface of the handicraft surface can be easily obtained by applying a bending pattern using an embossing roll on the top surface, which makes it possible to prevent dents, scratches, discoloration, etc. compared to wood. Physical properties can be secured.

以下、添付した図面に基づき、本発明の好適な実施例について詳述する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

ここで、各図面の構成要素について参照符号を付けるにあたって、同一の構成要素については、たとえ他の図面に示されていても、なるべく同一の符号で表記されたことに留意すべきである。   Here, in attaching reference numerals to the constituent elements of each drawing, it should be noted that the same constituent elements are denoted by the same reference numerals as much as possible even if they are shown in other drawings.

図１は、本発明による床材を示す断面図であり、図２は、本発明による床材の屈曲パターンを示す図面代用写真である。   FIG. 1 is a sectional view showing a flooring according to the present invention, and FIG. 2 is a drawing-substituting photograph showing a bending pattern of the flooring according to the present invention.

図１及び図２を参照すると、本発明の好適な一実施例による床材１００は、建築構造物の床に施工される床材であって、ベース層１１０と、前記ベース層１１０の上面に補強層１３１、印刷層１３３、透明層１３５が順次積層され、これらの層の一つ以上がＰＬＡ樹脂からなる表面層１３０と、を備え、前記表面層１３０の上面に屈曲パターン１３７が形成されたことを特徴とする。   Referring to FIGS. 1 and 2, a flooring 100 according to a preferred embodiment of the present invention is a flooring constructed on a floor of a building structure, and includes a base layer 110 and an upper surface of the base layer 110. A reinforcing layer 131, a printed layer 133, and a transparent layer 135 are sequentially laminated, and one or more of these layers are provided with a surface layer 130 made of PLA resin, and a bent pattern 137 is formed on the upper surface of the surface layer 130. It is characterized by that.

ここで、好ましくは、前記屈曲パターン１３７は、回転する一対のエンボスローラＲ間に表面層１３０を通過させて加圧する工程によって形成されてもよい（図３参照）。   Here, preferably, the bent pattern 137 may be formed by a process of passing the surface layer 130 between a pair of rotating embossing rollers R and applying pressure (see FIG. 3).

この場合、一対のエンボスローラＲは、一方向に押し込まれる表面層１３０の上面を押しつぶすことなく、一定の加圧力で屈曲パターン１３７を形成するように所定の間隙を維持している。また、一対のエンボスローラＲの少なくとも一つの外周縁には、表面層１３０の一面を加圧して屈曲パターン１３７を形成するための所定形状の突出部Ｒ１が設けられる。ここで、好ましくは、前記突出部Ｒ１は、上部ローラに形成されてもよい（図４参照）。   In this case, the pair of embossing rollers R maintain a predetermined gap so as to form the bent pattern 137 with a constant pressure without crushing the upper surface of the surface layer 130 pushed in one direction. Further, at least one outer peripheral edge of the pair of embossing rollers R is provided with a projecting portion R1 having a predetermined shape for forming a bent pattern 137 by pressing one surface of the surface layer 130. Here, preferably, the protrusion R1 may be formed on the upper roller (see FIG. 4).

このような構造のエンボスローラＲは、一側に設けられたモータ（図示せず）の動力を伝達され、一定の速度で回転しながら、一側に投入される表面層１３０の上面の長手方向に沿って所定の屈曲パターン１３７を繰り返して形成する。   The embossing roller R having such a structure is transmitted with the power of a motor (not shown) provided on one side, and rotates at a constant speed, while the longitudinal direction of the upper surface of the surface layer 130 thrown on one side A predetermined bending pattern 137 is repeatedly formed along

一方、ベース層１１０は、床材としてのある程度の厚さを形成してボリュームを与えるものであり、このようなベース層１１０は、ＭＤＦ（中密度繊維板）、ＨＤＦ（高密度繊維板）または合板のいずれか一つからなってもよい。ＭＤＦとＨＤＦは、周知のとおり、原木を磨き、粉に作ったものに膠を混ぜて固め、平らに圧縮させて、合板のように作ったものである。   On the other hand, the base layer 110 forms a certain amount of thickness as a flooring to give a volume, and such a base layer 110 is made of MDF (medium density fiberboard), HDF (high density fiberboard) or It may consist of any one of plywood. As is well known, MDF and HDF are made like a plywood by polishing a raw wood, mixing it with a paste, hardening it, and compressing it flatly.

さらに詳述すると、ＭＤＦは、全厚さにわたって、繊維分配が均一であり、組織が緻密であり、複雑な機械加工作業を面や側面を破裂することなく行うことができる。また、面が堅固かつ平滑であるので、装飾用フィルムやベニヤ等をオーバレイし、またはペイントするのにも極めて適合である。また、優れた安定性と機械加工性、高い強度のため、引き出しの側面や、キャビネットレール、鏡の枠、モールディングはもとより、本発明におけるように床材として用いられる。   More specifically, the MDF has a uniform fiber distribution, a dense structure, and a complex machining operation can be performed without rupturing the surface or side surface over the entire thickness. Further, since the surface is firm and smooth, it is extremely suitable for overlaying or painting decorative films, veneers and the like. Also, because of its excellent stability, machinability and high strength, it is used as a flooring material as in the present invention, as well as the sides of drawers, cabinet rails, mirror frames and moldings.

ＨＤＦは、密度が９００ｋｇ／ｍ以上の高密度繊維板であって、ＭＤＦよりも強度が遥かに高く、合板代替材として広く用いられ、家具材及び強化床材として多く用いられている。   HDF is a high-density fiberboard having a density of 900 kg / m or more, and has a much higher strength than MDF, and is widely used as a substitute for plywood, and is often used as a furniture material and a reinforced flooring material.

また、本発明の表面層１３０を構成するＰＬＡ樹脂は、ラクチドまたは乳酸の熱可塑性ポリエステルであって、トウモロコシ、ジャガイモ等から抽出した澱粉を発酵させて製造される乳酸を重合して製造される。   The PLA resin constituting the surface layer 130 of the present invention is a thermoplastic polyester of lactide or lactic acid, and is produced by polymerizing lactic acid produced by fermenting starch extracted from corn, potato or the like.

このようなＰＬＡ樹脂は、いくらでも再生可能であり、石油資源等の枯渇による問題点を解決することができ、廃棄過程でも、環境有害物質の排出量が他の樹脂、例えば、塩化ビニルよりも遥かに少なく、分解速度も速いという長所がある。   Such PLA resin can be regenerated as much as possible, can solve the problems caused by the depletion of petroleum resources, etc., and even in the disposal process, the amount of discharge of environmental hazardous substances is far greater than other resins such as vinyl chloride In addition, there is an advantage that the decomposition speed is high.

前記ＰＬＡ樹脂は、結晶質ＰＬＡ（ｃ‐ＰＬＡ）樹脂と、非晶質ＰＬＡ（ａ‐ＰＬＡ）樹脂に分けられるが、結晶質ＰＬＡ樹脂の場合、可塑剤がシート表面に流れ出るブリーディング現象が生じることがあるので、本発明では、非晶質ＰＬＡ樹脂を用いる。   The PLA resin is divided into a crystalline PLA (c-PLA) resin and an amorphous PLA (a-PLA) resin. In the case of a crystalline PLA resin, a bleeding phenomenon occurs in which the plasticizer flows out to the sheet surface. Therefore, an amorphous PLA resin is used in the present invention.

非晶質ＰＬＡ樹脂を用いる場合、１００％の非晶質ＰＬＡ樹脂を用いることが好ましいが、必要に応じて、結晶質と非晶質が共存するＰＬＡ樹脂が用いられてもよい。   When an amorphous PLA resin is used, it is preferable to use 100% amorphous PLA resin, but a PLA resin in which crystalline and amorphous coexist may be used if necessary.

また、前記ＰＬＡ樹脂は、成形時、非フタル酸系可塑剤や、溶融強度を補強する充填剤として、アクリル系共重合体、炭酸カルシウム、シリカゲル、酸化チタンが含まれてもよい。この場合、可塑剤は、樹脂成形による加工性、柔軟性等の用途に適合した物性を示すために用いられる添加物であつて、特に、本発明では、人体に有害でない非フタル酸系可塑剤が用いられる。   In addition, the PLA resin may contain a non-phthalic acid plasticizer or a filler for reinforcing the melt strength at the time of molding, such as an acrylic copolymer, calcium carbonate, silica gel, and titanium oxide. In this case, the plasticizer is an additive used for exhibiting physical properties suitable for applications such as processability and flexibility by resin molding, and in the present invention, in particular, a non-phthalic plasticizer that is not harmful to the human body. Is used.

このような材質と構造からなる表面層１３０は、熱硬化性メラミン樹脂の接着層１２０を介してベース層１１０の上面に積層される。   The surface layer 130 made of such a material and structure is laminated on the upper surface of the base layer 110 via a thermosetting melamine resin adhesive layer 120.

また、前記表面層１３０の上面には、表面層１３０の保護のためのＵＶコート層１３９が積層されることにより、木に比べて、凹み、引っかき、及び変色等を防ぐ等の優れた表面物性を確保することができる。   In addition, a UV coating layer 139 for protecting the surface layer 130 is laminated on the upper surface of the surface layer 130, so that superior surface properties such as prevention of dents, scratches, and discoloration are obtained compared to wood. Can be secured.

また、前記表面層１３０の下部には、床材１００の上・下側の全般的な撓みバランスを取るために、基材層（図示せず）がさらに設けられてもよい。   Further, a base material layer (not shown) may be further provided below the surface layer 130 in order to balance the upper and lower sides of the flooring 100 in general.

以上のような構成の本発明による床材１００は、表面層１３０を回転する一対のエンボスローラＲ間に通過させて加圧する工程により形成される屈曲パターン１３７によって、まるで作業者が床材の表面層１３０の表面をかんな等の道具を用いて手作業で直接削ったような表面の質感が得られ、これにより、床材１００を用いる消費者にとって手工芸的な審美感を感じさせるようになる。   The flooring 100 according to the present invention having the above-described configuration is as if the operator has the surface of the flooring by the bending pattern 137 formed by passing the surface layer 130 between a pair of rotating embossing rollers R and applying pressure. The surface texture of the surface of the layer 130 can be obtained by directly cutting the surface of the layer 130 manually using a tool such as a planer. This makes a handcrafted aesthetic feel to the consumer using the flooring 100. .

以上、本発明を特定の好適な実施例を挙げて図示して説明したが、本発明は、上記した実施例に限定されず、本発明の技術思想を逸脱しない範囲内で、様々な変更と修正が可能であることは言うまでもない。   The present invention has been illustrated and described with reference to specific preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made without departing from the technical idea of the present invention. It goes without saying that corrections are possible.
