Description

마루 바닥재{Flooring having ＰＬＡ layer}Flooring Flooring {Flooring having PLAA layer}

본 발명은 마루 바닥재에 관한 것으로, 보다 상세하게는 바닥재의 자연적인 표면 질감을 향상시킬 수 있도록 핸드크래프트(Hand-Craft, 수공업) 효과를 용이하게 구현할 수 있으며, 눌림, 긁힘 및 변색 등을 방지할 수 있는 마루 바닥재에 관한 것이다.
The present invention relates to a flooring flooring, and more particularly, it is possible to easily implement a handcraft (Hand-Craft, handcraft) effect to improve the natural surface texture of the flooring, and to prevent pressing, scratching and discoloration, etc. It is about the flooring which can be floor.

일반적으로, 건축물의 실내 바닥에 시공된 콘크리트면 등을 커버, 장식하고 고급스러운 실내 분위기를 연출하면서 전체적으로 자연스런 나무 질감 효과를 갖도록 하기 위해, 마루 바닥재를 시공하고 있다.In general, the flooring material is constructed to cover and decorate the concrete floor which is constructed on the indoor floor of the building, and to have a natural wood texture effect as a whole while producing a luxurious indoor atmosphere.

합판 제조 기술의 발달과 더불어 원목의 활용도를 높이고, 물성이 우수한 합판 등이 많이 제공되고 있음은 주지된 바와 같은데, 합판은 원목을 가공함에 있어 원목으로부터 각목이나 판재를 직접 절단하지 아니하고, 원목을 둥글게 깎아내어 얇게 형성된 나무 박판을 재단하여 그 결이 서로에 대해 수직방향으로 배치되는 방법으로 적층하고, 접착제 등으로 서로의 박판을 고착하여 일정한 두께를 갖는 판상체로 성형하여 제조하게 된다.It is well known that with the development of plywood manufacturing technology, the utilization of solid wood is improved and a lot of plywood with excellent physical properties are provided, but plywood does not cut the lumber or plate directly from solid wood, but rounds the solid wood. The thin thin plated wood sheets are cut and laminated in a manner in which the grains are disposed in a vertical direction with respect to each other, and the thin plates are adhered to each other with an adhesive or the like to be formed into a plate-like body having a certain thickness.

이렇게 함으로써, 합판은 결을 갖는 나무판재에 비해 일정한 결의 방향을 갖고 있지 않아 뒤틀림 등이 거의 없으며, 모든 방향으로 내인성 등이 향상되는 등의 장점을 갖게 된다. 그러나 이러한 방법으로 가공된 합판은 그 가공특성상 나무 본연의 결 등 무늬가 없어 장식성이 저하되는 문제점이 있다.By doing so, the plywood does not have a certain grain direction compared to the wood plate having a grain, so there is almost no warpage and the like, and the endurance and the like are improved in all directions. However, the plywood processed by this method has a problem that the decoration property is deteriorated because there is no texture of the wood itself due to its processing characteristics.

따라서, 이러한 합판을 사용하여 마루 바닥 등의 바닥재나 기타 건축자재용으로 사용되는 경우, 이를 다시 무늬목 등으로 표면을 장식하고, 그 표면을 수지도료로 코팅 처리하여 내수성 및 긁힘 현상 등에 대하여 내성이 부여되도록 하고 있다.Therefore, when such plywood is used for flooring materials such as flooring and other building materials, the surface is decorated with veneer and the surface thereof is coated with a resin paint to impart resistance to water resistance and scratching .

이러한 형태의 실내 마루 바닥재를 제조하는 일례로, 합판의 상면에 무늬목 단판을 요소수지로 접착하여 마루판재를 제조하는 방법이 있으나 제조원가의 상승을 가져오고, 내수 및 내열성이 매우 취약한 단점이 있다.As an example of manufacturing an indoor floorboard of this type, there is a method of manufacturing the floorboard material by adhering the veneer veneer to the upper surface of the plywood with urea resin, but the production cost rises, water and heat resistance is very weak.

또한 나무를 표면으로 사용하는 마루 바닥재는 현실성을 확보하기 위해 핸드크래프트 효과를 구현하게 되는데, 이와 같은 핸드크래프트 효과는 일일이 수작업으로 진행하게 됨에 따라 생산성을 확보하기가 어렵다. 특히 상기 핸드크래프트 효과는 일반적으로 사용되는 0.5㎜ 무늬목에 구현하기가 어렵고 적어도 2㎜ 이상의 원목을 사용해야 함에 따라 제조원가의 상승 요인이 되는 문제점이 있다.
In addition, the flooring material using wood as a surface implements a handcraft effect in order to secure reality, such handcraft effect is difficult to secure productivity as it is carried out manually by hand. In particular, the handcraft effect is difficult to implement in the commonly used 0.5mm veneer, there is a problem that the increase in the manufacturing cost due to the use of at least 2mm solid wood.

본 발명은 상술한 문제점을 해결하고자 안출된 것으로, 베이스층의 상면에 적층되는 표면층을 나무 대신 ＰＬＡ(Poly Lactic Acid) 수지를 이용하여 형성해줌으로써 친환경성을 확보할 수 있고, 표면층의 생산시 상면에 엠보롤(Embo-Roll)을 이용한 굴곡패턴을 적용하여 수공예적인 표면 질감을 용이하게 구현할 수 있으며, 나무 대비 눌림, 긁힘 및 변색 등을 방지할 수 있도록 한 마루 바닥재를 제공하는데 그 목적이 있다.
The present invention has been made to solve the above problems, by forming a surface layer to be laminated on the upper surface of the base layer by using a poly actic acid (PLA) resin instead of wood to ensure environmental friendliness, the upper surface during the production of the surface layer The embossing pattern using embossing (Embo-Roll) can be applied to easily implement the surface texture of the hand, and its purpose is to provide a flooring material that can prevent pressing, scratching and discoloration compared to wood.

도 1 및 도 2를 참조하면, 본 발명의 바람직한 일 실시예에 따른 마루 바닥재(100)는, 건축 구조물의 바닥에 시공되는 마루 바닥재로서, 베이스층(110)과, 상기 베이스층(110)의 상면에 보강층(131), 인쇄층(133), 투명층(135)이 순차적으로 적층되되 이들 층 중 하나 이상이 ＰＬＡ수지로 이루어지는 표면층(130)을 포함하여 구성되며, 상기 표면층(130)의 상면에 굴곡패턴(137)이 형성된 것을 특징으로 한다.1 and 2, the flooring flooring material 100 according to an exemplary embodiment of the present invention is a flooring material installed on the floor of a building structure, and includes a base layer 110 and the base layer 110. The reinforcement layer 131, the printing layer 133, and the transparent layer 135 are sequentially stacked on the upper surface, and at least one of the layers includes a surface layer 130 made of PLA resin, and is disposed on the upper surface of the surface layer 130. The bending pattern 137 is formed.

여기서, 바람직하게는 상기 굴곡패턴(137)은 회전하는 한 쌍의 엠보롤러(R) 사이에 표면층(130)을 통과시켜서 가압해주는 공정을 통해 형성될 수 있다.(도 3 참조)Here, preferably, the bending pattern 137 may be formed through a process of pressing the surface layer 130 through a pair of rotating emboss rollers R (see FIG. 3).

이 경우 한 쌍의 엠보롤러(R)는 일방향으로 압입되는 표면층(130)의 상면을 짓이기지 않고 일정한 가압력으로 굴곡패턴(137)을 형성해줄 수 있도록 소정의 간극을 유지하고 있다. 그리고 한 쌍의 엠보롤러(R) 중 적어도 하나의 외주연에는 표면층(130)의 일면을 가압하여 굴곡패턴(137)을 형성하기 위한 소정 형상의 돌출부(R1)가 구비된다. 여기서, 바람직하게는 상기 돌출부(R1)는 상부롤러에 형성될 수 있다.(도 4 참조)In this case, the pair of emboss rollers R maintains a predetermined gap so that the bending pattern 137 can be formed at a predetermined pressing force without crushing the upper surface of the surface layer 130 press-fitted in one direction. At least one outer periphery of the pair of emboss rollers R is provided with a protrusion R1 having a predetermined shape for pressing the one surface of the surface layer 130 to form the bending pattern 137. Here, preferably, the protrusion R1 may be formed on the upper roller. (See FIG. 4).

이와 같은 구조의 엠보롤러(R)는 일측에 구비된 모터(미도시)의 동력을 전달받아 일정 속도로 회전하면서 일측으로 투입되는 표면층(130)의 상면 길이방향을 따라 소정의 굴곡패턴(137)을 반복적으로 형성해주게 된다.The embossing roller R having such a structure receives a power of a motor (not shown) provided on one side and rotates at a predetermined speed, while predetermined curvature patterns 137 are provided along the longitudinal direction of the upper surface of the surface layer 130 which is introduced to one side. Will form repeatedly.

한편, 베이스층(110)은 바닥재로서 어느 정도의 두께를 부여하여 볼륨을 형성해주는 것으로, 이러한 베이스층(110)은 ＭＤＦ(중밀도 섬유판), ＨＤＦ(고밀도 섬유판) 또는 합판 중 어느 하나로 이루어질 수 있다. ＭＤＦ과 ＨＤＦ는 이미 알려진 바와 같이, 원목을 갈아 가루로 만든 것에 아교를 섞어 뭉쳐 평평하게 압축시켜 합판처럼 만든 것이다.On the other hand, the base layer 110 is to form a volume by giving a certain thickness as a flooring material, the base layer 110 may be made of any one of MDF (medium density fiberboard), HDF (high density fiberboard) or plywood. . As already known, MDF and HDF are made by mixing wood flour with glues, compressing them flatly and making them like plywood.

좀더 구체적으로 설명해보면, ＭＤＦ는 전 두께에 걸쳐 섬유분배가 균일하고 조직이 치밀하여 복잡한 기계 가공작업을 면이나 측면의 파열 없이 수행할 수 있다. 또한 면이 견고하고 평활하여 장식용 필름이나 베니어 등을 오버레이 하거나, 페인팅하는데에도 아주 적합하다. 아울러 뛰어난 안정성과 기계 가공성, 높은 강도 때문에 서랍 측면이나 캐비넷 레일, 거울 틀, 몰딩은 물론 본 발명에서와 같이 바닥재로 사용된다.More specifically, the MDF can perform complicated machining operations with uniform fiber distribution over the entire thickness and with a dense structure, without rupture of the side or side. It is also very suitable for overlaying or painting decorative films, veneers, etc., because the surface is solid and smooth. In addition, because of its excellent stability, machinability and high strength, the drawer side, cabinet rail, mirror frame and molding are of course used as flooring as in the present invention.

ＨＤＦ는 밀도가 900㎏/m 이상의 고밀도 섬유판으로 강도면에서 ＭＤＦ 보다 월등히 높아 합판 대체재로 널리 사용되고, 가구재 및 강화 마루로 많이 사용된다.HDF is a high-density fiberboard with a density of more than 900 kg / m, which is much higher than MDF in terms of strength, and is widely used as a substitute for plywood, and is widely used as furniture and reinforced flooring.

또한 본 발명의 표면층(130)을 구성하는 ＰＬＡ(Polylactic acid) 수지는 락 타이드 또는 락트산의 열가소성 폴리에스테르로서, 옥수수, 감자 등에서 추출한 전분을 발효시켜 제조되는 락트산을 중합시켜 제조될 수 있다. In addition, the polylactic acid (PLA) resin constituting the surface layer 130 of the present invention is a thermoplastic polyester of lactide or lactic acid, and may be prepared by polymerizing lactic acid prepared by fermenting starch extracted from corn or potato.

이러한 ＰＬＡ 수지는 얼마든지 재생이 가능하여 석유 자원 등의 고갈에 따른 문제점을 해결할 수 있고, 폐기 과정에서도 환경 유해 물질의 배출량이 다른 수지 예컨대 염화비닐보다 훨씬 적고, 분해 속도도 빠른 장점이 있다.Such PLA resin can be regenerated as much as possible, thereby solving the problems due to depletion of petroleum resources, etc., and also has a merit that the emission of environmentally harmful substances is much smaller than that of other resins such as vinyl chloride and disintegration rate.

상기 ＰＬＡ 수지는 결정질 ＰＬＡ(c-ＰＬＡ) 수지와 비정질 ＰＬＡ(a-ＰＬＡ) 수지로 구분될 수 있으며, 결정질 ＰＬＡ 수지의 경우 가소제가 시트 표면으로 흘러나오는 브리딩 현상이 발생할 수 있으므로 본 발명에서는 비정질 ＰＬＡ 수지를 이용한다.The PLA resin may be classified into a crystalline PLA (c-PLA) resin and an amorphous PLA (a-PLA) resin. In the case of the crystalline PLA resin, a bleeding phenomenon may occur in which the plasticizer flows to the sheet surface. Resin is used.

비정질 ＰＬＡ 수지를 이용하는 경우 100% 비정질 ＰＬＡ 수지를 사용하는 것이 바람직하나, 필요에 따라서는 결정질과 비정질이 공존하는 ＰＬＡ 수지가 이용될 수도 있다.When an amorphous PLA resin is used, it is preferable to use 100% amorphous PLA resin, but PLA resin in which crystalline and amorphous coexist may be used if necessary.

또한 상기 ＰＬＡ 수지는 성형할 때 비프탈레이트계 가소제나, 용융 강도를 보강하는 충전제로는 아크릴계 공중합체, 탄산칼슘, 실리카 겔, 산화 티타늄이 포함될 수 있다. 이 경우 가소제는 수지 성형에 따른 가공성, 유연성 등 용도에 맞는 물성을 나타낼 수 있도록 사용하는 첨가물로 특히 본 발명에서는 인체에 유해하지 않은 비프탈레이트계 가소제가 사용된다.The PLA resin may include a non-phthalate plasticizer when molding, and an acrylic copolymer, calcium carbonate, silica gel, or titanium oxide as fillers for reinforcing the melt strength. In this case, the plasticizer is an additive which is used so as to exhibit physical properties suitable for use such as workability, flexibility and the like according to resin molding.
