Description
본 발명은 바닥재용 천연소재층 조성물, 이의 제조방법 및 이를 포함하는 바닥장식재에 관한 것으로, 좀 더 상세하게는 목분 또는 왕겨로부터 선택된 천연소재에 대해 카슈도료 및 아마유의 혼합결합제를 결합제로서 포함하는 바닥재용 천연소재층 조성물, 이의 제조방법 및 이를 포함하는 바닥장식재에 관한 것이다.The present invention relates to a natural material layer composition for flooring, a method for manufacturing the same and a flooring material comprising the same, and more particularly, a flooring comprising a mixed binder of cashew paint and linseed oil as a binder for a natural material selected from wood flour or chaff. The present invention relates to a natural material layer composition, a method for preparing the same, and a flooring material including the same.
종래부터 바닥장식재는 PVC를 주원료로 하여, 일반적으로 하부로부터 하지층, 발포층, 유리섬유 함침층, 인쇄층, 상지층 및 UV 코팅층으로 구성된 PVC계 바닥재가 주종을 이루고 있다. PVC 바닥재는 시공이 간편하고 저렴하다는 장점을 가지고 있으나, 인위적인 질감과 짧은 내구성 등 단점이 있다. 더구나, 최근 소비자들의 제품 선택취향이 자연스러운 질감이나 문양을 갖는 자연 친화적인 제품을 선호하고 있는 추세이기 때문에, 목재와 같은 천연소재를 이용한 목질 마루판 등의 제품이 제조되고 있다. 이러한 천연원목을 이용한 목질 마루판은 천연질감과 긴 내구성을 갖는 장점이 있지만, 원목의 전처리, 절단, 건조, 표면처리 등의 수많은 공정과 시공시 평활성 유지를 위한 전문 시공인력이 필요하며 단가가 높고 시공성이 떨어질 뿐만 아니라, 원목 전처리시 포르말린을 방산하는 결정적인 단점이 있다.Conventionally, the flooring material is mainly made of PVC, PVC-based flooring mainly composed of a base layer, foam layer, glass fiber impregnated layer, printing layer, upper layer and UV coating layer from the bottom. PVC flooring has the advantage of easy construction and low cost, but has disadvantages such as artificial texture and short durability. In addition, since the consumer's current product preferences tend to favor natural-friendly products having natural textures or patterns, products such as wooden floorboards using natural materials such as wood have been manufactured. Although wood floorboards using such natural wood have the advantages of having a natural texture and long durability, many construction processes such as pretreatment, cutting, drying, and surface treatment of wood and professional construction personnel are required for maintaining smoothness during construction. Not only does this fall, but there is a decisive disadvantage of dissipating formalin in the pretreatment of wood.
또한 바닥장식재에 자연스러운 질감과 입체감을 부여하기 위하여 천연 목무늬 등의 인쇄무늬를 형성하거나 목분과 PVC칩을 이용하여 목분칩층을 형성하는 방법(한국 실용신안 공개번호 제99-7018호)이 사용되어 오고 있다. 그러나, 이러한 방법은 자연적인 질감을 나타내는 효과보다 인위적인 질감을 나타내는 효과가 더욱 강한 문제가 있었다. 또한, 바닥장식재에 자연스러운 질감을 나타내기 위한 다른 방법으로는, 바닥장식재 일부에 목재칩을 산포하고 그 위에 액상졸을 함침시키는 방법이 있으나, 함침후 천연소재에 함유되어 있는 기포가 발생하는 문제점이 있었다. 이러한 기포의 발생을 억제하기 위한 액상졸을 얇게 함침시킨 경우 목재칩이 상기 졸의 상부로 토출되어 불량발생의 원인이 되기도 하고, 목재칩이 겹쳐진 경우에는 평탄한 면을 만들기 어려웠다. 이러한 문제를 해결하고자 최근에는 점착층 위에 천연소재의 칩을 산포한 후 PVC 파우더로 상부층을 형성하는 방법이 한국공개특허 제2000-7992호에 기재되어 있지만, 여기서는 바닥장식재층의 일부층에만 한정하여 천연소재를 적용하였고 천연소재층이 상부로 표출되지 않기 때문에 천연소재의 질감 표출에는 한계가 있었다.In addition, in order to give a natural texture and three-dimensional appearance to the flooring material, a method of forming a printed pattern such as a natural wood pattern or a wood chip chip layer using wood flour and PVC chips (Korean Utility Model Publication No. 99-7018) is used. Coming. However, this method has a problem in that an artificial texture effect is stronger than an natural texture effect. In addition, as another method for showing the natural texture of the flooring material, there is a method of spreading wood chips in some of the flooring material and impregnated with a liquid sol thereon, but the problem that air bubbles contained in the natural material occurs after the impregnation there was. When the liquid sol for suppressing the occurrence of such bubbles is impregnated thinly, the wood chips are discharged to the upper portion of the sol to cause defects, it is difficult to make a flat surface when the wood chips overlap. Recently, in order to solve this problem, a method of forming an upper layer with PVC powder after dispersing a chip of a natural material on an adhesive layer is described in Korean Patent Laid-Open Publication No. 2000-7992, but here, only a part of the floor decorative layer Natural materials were applied and there was a limit to the texture of natural materials because the natural material layer was not exposed upward.
이에 본 발명자들은 종래 문제점을 해결하고 자연스러운 느낌을 부여할 수 있는 바닥장식재를 제공하기 위해 연구한 결과, 왕겨 또는 목분의 천연소재를 이용하는 바닥재 조성물을 개발하였으며, 본 발명은 이에 기초하여 완성되었다.Accordingly, the present inventors have developed a flooring composition using a natural material of chaff or wood flour as a result of research to solve the conventional problems and to give a natural decorative feel, the present invention was completed based on this.
따라서, 본 발명의 목적은 종래의 PVC 바닥재와 목질 마루판의 단점을 해결하고 자연스러운 질감과 입체감을 가지며 환경친화적인 바닥재용 천연소재층 조성물, 이의 제조방법 및 이를 포함하는 바닥장식재를 제공하는데 있다.Accordingly, it is an object of the present invention to solve the disadvantages of conventional PVC flooring and wood floorboards, and to provide a natural texture and three-dimensional impression environment-friendly natural material layer composition for flooring, a method of manufacturing the same and a flooring material comprising the same.

또한, 상기 본 발명의 또 다른 목적을 달성하기 위한 바닥장식재는, 다층구조의 바닥장식재에 있어서, 전술한 방법에 의해 제조된 천연소재층 조성물을 벨트 프레스, 칼렌더 가공 또는 T-다이 압출의 공정을 이용하여 천연소재층을 제조한 다음, 이를 바닥재 층구조의 일정층으로 적용함으로써 제조된다.In addition, the flooring material for achieving the another object of the present invention, in the flooring material of a multi-layer structure, the process of belt pressing, calendar processing or T-die extrusion of the natural material layer composition prepared by the above-described method It is prepared by using a natural material layer, and then applying it as a predetermined layer of the flooring layer structure.
도 1 내지 도 5는 본 발명에 따른 다양한 바닥장식재의 측단면의 구성을 개략적으로 도시한 개략도이다.1 to 5 are schematic diagrams schematically showing the configuration of the side cross-section of the various floor decoration according to the present invention.
이하, 본 발명을 첨부된 도면을 참조하면서 구체적으로 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
전술한 바와 같이, 본 발명에 따른 바닥재용 천연소재층 조성물은 목분 또는 왕겨로부터 선택된 천연소재와, 카슈도료 및 아마유의 혼합결합제를 포함하며, 이들을 리본 블렌더 믹서에 함께 투입하여 블렌딩함으로써 제조된다.As described above, the natural material layer composition for flooring according to the present invention comprises a natural binder selected from wood flour or chaff and a mixed binder of cashew paint and linseed oil, which are prepared by blending them together in a ribbon blender mixer.
상기 천연소재는 평균입경 100∼500㎛의 목분 또는 평균입경 30∼200㎛의 왕겨로부터 선택된다. 이 때, 상기 천연소재 내부에 잔존해 있는 수분의 영향으로 최종 제품의 내수성 및 기계적 물성이 나빠질 수 있기 때문에, 전처리하는 것이 바람직하다. 우선 드라이 오븐에서 충분히 건조시킨 후, 상기 건조된 천연소재 100중량부에 대해 카슈도료 30∼80중량부 및 카슈도료의 경화 및 건조속도를 빠르게 하기 위해 상기 카슈도료 100중량부에 대해 열경화촉진제인 헥사아민(hexamine)(헥사 메틸렌 테트라아민(hexa methylene tetramine)) 1∼5중량부를 리본 블렌더에 넣고 50∼100℃에서 함침시키고 건조상태에 따라 블렌딩 시간을 조절하여 전처리시킨다. 상기 전처리 공정에 있어서, 카슈도료의 함량이 천연소재에 대해 30중량부 미만이면 목분이나 왕겨 입자 전체에 골고루 표면처리하는 것이 어려우며, 80중량부를 초과하면 표면처리의 효과는 우수하지만, 함침후의 건조공정에 소요되는 시간이 너무 길어지게 된다. 또한, 열경화촉진제인 헥사아민의 함량이 카슈도료 100중량부에 대해 1중량부 미만이면 페놀성 유도체 합성수지가 주원료인 카슈도료의 경화반응을 개시시키기 어렵고, 5중량부를 초과하면 경화반응 중 헥사아민의 분해로 파생되는 질소가스의 영향으로 기포생성 등의 불량원인이 된다.The natural material is selected from wood flour having an average particle diameter of 100 to 500 µm or rice husk having an average particle diameter of 30 to 200 µm. At this time, the water resistance and mechanical properties of the final product may be deteriorated under the influence of moisture remaining inside the natural material, it is preferable to pretreat. First, after drying sufficiently in a dry oven, 30 to 80 parts by weight of cashew paint and 100 parts by weight of the cashew paint to accelerate the curing and drying rate of the cashew paint, based on 100 parts by weight of the dried natural material, 1 to 5 parts by weight of hexamine (hexamethylene tetramine) is placed in a ribbon blender, impregnated at 50 to 100 ° C, and pretreated by adjusting the blending time according to the dry state. In the pre-treatment step, if the content of the cashew paint is less than 30 parts by weight based on the natural material, it is difficult to surface-treat the wood powder or chaff particles evenly, and when it exceeds 80 parts by weight, the surface treatment is excellent, but the drying step after impregnation The time it takes to become too long. In addition, when the content of hexaamine, which is a thermosetting accelerator, is less than 1 part by weight based on 100 parts by weight of cashew paint, it is difficult to initiate the curing reaction of the cashew material whose main ingredient is a phenolic derivative synthetic resin. The effect of nitrogen gas, which is derived from the decomposition of, causes defects such as bubble generation.
카슈(cashew) 도료라 함은 자연에서 채취하는 카슈열매에서 추출한 액을 정제한 것이나, 최근에는 아나카르드산, 카다놀, 티르시올, 우르시올, 타롤 등의 페놀성 유도체 단량체로부터 선택된 하나 또는 이들의 혼합물 60∼95중량부, 파라포름알데히드 1∼40중량부, 촉매 0.05∼2.5중량부를 사용하여 80∼200℃에서 축중합시켜 페놀성 유도체 수지를 제조한 후, 상기 수지에 대하여 0.5∼2.5중량부의 유변성 알키드 수지를 첨가하여 변경시킨 고형분 수지를 용제로 희석하여 천연의 카슈오일과 동일한 효과를 나타낼 수 있도록 하였는데, 본 발명에서는 상술한 고형분 수지인 페놀성 유도체 합성수지 20∼80중량부, 미네랄 스피리트와 같은 지방족 탄화수소계 카슈도료 희석제 80∼20중량부, 망간, 칼슘, 납 및 코발트 등의 금속건조제 1∼3중량부, KF-69와 같은 실리콘 소포제 0.1∼0.3중량부 및 MEK-옥신과 같은 피막방지제 0.1∼0.3중량부를 포함한 카슈도료를 사용한다.Cashew paint is a purified liquid from a cashew fruit collected in nature, but recently selected from phenolic derivative monomers such as anacardic acid, cardanol, tyrsirol, ursol, tarol, or the like. 60 to 95 parts by weight of the mixture of 1 to 40 parts by weight of paraformaldehyde, 0.05 to 2.5 parts by weight of the catalyst was condensation-polymerized at 80 to 200 ℃ to prepare a phenolic derivative resin, 0.5 to 2.5 parts by weight relative to the resin The solid resin modified by the addition of negative rheological alkyd resin was diluted with a solvent so as to exhibit the same effect as natural cashew oil. In the present invention, 20 to 80 parts by weight of the phenolic derivative synthetic resin, which is the solid resin, mineral spirit Aliphatic hydrocarbon-based cashew paint diluent such as 80 to 20 parts by weight, metal drying agents such as manganese, calcium, lead and cobalt 1 to 3 parts by weight, silicone such as KF-69 Posay 0.1-0.3 uses Cache paint containing 0.1 to 0.3 weight parts of the coating agent, such as parts by weight and MEK- auxin.
카슈도료는 건성유로서 건조가 느린 단점이 있으나, 천연 옻칠과 동일하게 광택이 우수하며 내열성, 용제성, 내수성 및 내약품성이 뛰어나고 방오성과 방충효과까지 겸비한다. 따라서, 본 발명에서는 기존 전통공예나 일부 공업용으로 사용되는 카슈도료의 건조가 느린 단점을 경화촉진제를 이용하여 보완함으로써 목분이나 왕겨와 같은 천연소재를 이용한 바닥장식재 제조시에 결합제로서 이용하고, 또한 후술하는 바와 같이 바닥장식재의 표면도장에도 적용한다. 본 발명에서 결합제로서사용되는 카슈도료는 아마유를 함께 사용함으로써 건조공정 단축 및 기계적 물성 상승에 효과가 있다.Cashew paint has a disadvantage of slow drying as a dry oil, but has excellent gloss, excellent heat resistance, solvent resistance, water resistance and chemical resistance as well as natural lacquer and combines antifouling and insect repellent effects. Accordingly, in the present invention, by using a curing accelerator to compensate for the slow drying of the cashew paint used for traditional crafts and some industrial use as a binder in the manufacture of flooring materials using natural materials such as wood flour or chaff, and also described later The same applies to the surface coating of floor coverings. The cashew paint used as a binder in the present invention is effective in shortening the drying process and increasing mechanical properties by using flax oil together.
본 발명에 따른 천연소재층 조성물은, 전술한 바와 같이 전처리된 천연소재 100중량부에 대해 카슈도료 및 아마유의 혼합결합제 30∼100중량부를 포함하는데, 상기 혼합결합제의 함량이 30중량부 미만이면 천연소재 결합제로서의 역할이 미미하여 강도가 약해지는 문제가 있으며 100중량부를 초과하면 결합제 증량에 따른 기계적 물성의 증가보다는 건조공정에 소요되는 시간이 길어지는 단점이 있다.The natural material layer composition according to the present invention includes 30 to 100 parts by weight of a mixed binder of cashew paint and linseed oil with respect to 100 parts by weight of the pretreated natural material as described above, and when the content of the mixed binder is less than 30 parts by weight of natural There is a problem in that the strength is weakened because the role as a material binder is insignificant, and if it exceeds 100 parts by weight has a disadvantage in that the time required for the drying process rather than the increase in mechanical properties due to the binder increase.
또한, 상기 카슈도료 및 아마유의 혼합결합제는 카슈도료 100중량부에 대해 아마유 20∼70중량부 및 헥사아민 1∼5중량부를 혼합하여 제조되는데, 아마유의 함량이 20중량부 미만이면 전체 혼합결합제의 건조공정이 느려지고, 70중량부를 초과하면 카슈도료의 특성을 나타내기 곤란한 문제가 생긴다. 또한, 헥사아민의 함량이 1중량부 미만이면 페놀성 유도체 합성수지가 주원료인 카슈도료의 경화반응을 개시시키기 어렵고, 5중량부를 초과하면 경화반응 중 헥사아민의 분해로 파생되는 질소가스의 영향으로 기포생성 등의 불량원인이 된다.In addition, the mixed binder of the cashew paint and linseed oil is prepared by mixing 20 to 70 parts by weight of flax oil and 1 to 5 parts by weight of hexaamine with respect to 100 parts by weight of cashew paint, if the amount of flax oil is less than 20 parts by weight of the total binder When the drying process is slow and exceeds 70 parts by weight, a problem arises in that it is difficult to exhibit the characteristics of the cashew paint. In addition, when the content of hexaamine is less than 1 part by weight, it is difficult to initiate the curing reaction of the cashew paint whose phenolic derivative synthetic resin is the main raw material. When the content of the hexaamine is more than 5 parts by weight, bubbles are affected by the nitrogen gas derived from decomposition of hexaamine during the curing reaction. It may cause a defect such as generation.
이렇게 제조된 바닥재용 천연소재층 조성물을 일반적인 벨트 프레스, 칼렌더 가공 및 T-다이 압출공정을 이용하여 천연소재층으로 제조할 수 있다.The natural material layer composition for the flooring thus prepared may be manufactured as a natural material layer using a general belt press, calendar processing and T-die extrusion process.
또한, 천연소재 시트에 대한 디자인의 차별을 얻기 위해서, 칼렌더 가공이나 T-다이를 통해 제조된 천연소재 시트에 대해 다양한 무늬를 직접 인쇄하거나 전사지를 부착시킨 후 카슈도료 또는 UV-경화된 카슈도료를 도포할 수 있다. 바닥장식재의 제조시에 인쇄층의 색상에 따라 적절한 투명성의 카슈도료를 선별하여 도포함으로써, 카슈도료의 특성인 천연 옻칠과 유사한 색상과 질감을 나타낼 수 있다. 인쇄층의 표면보호를 위해 종래의 우레탄 아크릴레이트를 기본으로 한 무색투명의 UV 경화도료를 최종적으로 도포할 수도 있다.In addition, in order to differentiate the design of the natural sheet, various patterns can be directly printed on the natural sheet produced through calender processing or T-die or the transfer paper is attached, and then the cashew paint or UV-cured cashew paint is applied. It can be applied. When the flooring material is manufactured, by selecting and applying a suitable transparent cashew paint according to the color of the printing layer, the color and texture similar to those of the natural lacquer, which is a characteristic of the cashew paint, can be exhibited. In order to protect the surface of the printed layer, a colorless and transparent UV cured paint based on a conventional urethane acrylate may be finally applied.
이러한 천연소재의 바닥재는 륨과 동일한 규격의 제품생산이 가능하기 때문에 낱장씩 사용하는 타일류에 비해 사용이 간편하며, 일예로서 최하층에 부직포, 황마, 모시, 직포층으로 구성되어 있을 경우에는 기존 PVC 기저하지층(륨, 타일)에 비해 시공접착제와의 접착력도 우수하다.The flooring of such natural materials is easy to use compared to the tiles used one by one because it is possible to produce products of the same standard as the rium, and as an example, when the lower layer is composed of nonwoven fabric, jute, ramie, and woven fabric, the existing PVC The adhesive strength with the construction adhesive is also superior to the base layer (lium, tile).
바닥재 층구조에 있어서, 천연소재층이 삽입된 예들을 첨부된 도면을 참조하여 설명하지만, 본 발명이 이에 한정되는 것은 아니다.In the flooring layer structure, examples in which a natural material layer is inserted will be described with reference to the accompanying drawings, but the present invention is not limited thereto.

도 5에는 두께 2.0∼2.6mm의 천연소재층 상단에 인쇄층을 부착하고, 그 상부에 카슈도료나 UV 경화형 카슈도료 또는 UV도료를 도포하고, 천연소재층 하단에 하지층을 부착한 바닥장식재가 도시되어 있다.In Figure 5, the printing layer is attached to the top of the natural material layer of 2.0 to 2.6mm thickness, the cashew paint or UV curable cashew paint or UV coating is applied on the top, and the flooring material is attached to the bottom layer of the natural material layer Is shown.
상기 최상층에 카슈도료나 UV 경화형 카슈도료 또는 UV층을 도포할 경우에는 20㎛의 두께가 바람직하다.When the cashew paint, the UV curable cashew paint or the UV layer is applied to the uppermost layer, a thickness of 20 μm is preferable.
