Description

마루바닥재 및 그 제조방법{WOOD FLOORING AND MANUFACTURING METHOD THEREOF}Flooring flooring and its manufacturing method {WOOD FLOORING AND MANUFACTURING METHOD THEREOF}

본 발명은 마루바닥재에 관한 것으로, 더욱 상세하게는, 마루바닥재의 표면강도를 강화시켜 내충격성을 향상시키고 합판보다 저렴한 중밀도섬유판(MDF) 또는 고밀도섬유판(HDF)로 치수를 보강하며 아울러 마루바닥의 무늬를 다양하게 구현하면서도 제조공정을 간소화시켜 제조에 소요되는 비용 및 시간을 단축시킬 수 있는 마루바닥재 및 그 제조방법에 관한 것이다.The present invention relates to a flooring material, and more particularly, to improve the impact resistance by strengthening the surface strength of the flooring material and to reinforce the dimensions with a medium density fiberboard (MDF) or a high-density fiberboard (HDF) that is cheaper than plywood, The present invention relates to a flooring material and a method of manufacturing the same, which may reduce the cost and time required for manufacturing by simplifying the manufacturing process while implementing various patterns.

종래 마루 바닥재는 도1에 도시된 바와 같이 합판 등에 무늬목이 결합된 마루바닥재가 많이 사용되고 있다. 이러한 마루바닥재에서 무늬목(2)은 원목을 슬라이서를 이용하여 0.182mm 내지 0.5mm 두께로 얇게 절삭함으로써 얇은 무늬목을 얻고, 이를 MDF, HDF, 합판, OSB 등의 판재 또는 목질 재료를 바탕으로 하는 복합 재료 등의 표면에 접합하여 형성하게 된다. 이 때 원목으로부터 슬라이스된 천연 무늬목(2)은 시트형태로 제작되어 기재인 합판(4) 등에 결합되고, 그 상측에 도장층(1)이 형성되어 마루바닥재로 많이 사용되고 있다.Conventionally, as shown in FIG. 1, flooring materials in which veneer is coupled to plywood or the like are used as shown in FIG. In such flooring material veneer (2) is obtained by cutting the wood thinly to 0.182mm to 0.5mm thickness using a slicer to obtain a thin veneer, which is based on a plate or wood material such as MDF, HDF, plywood, OSB It is formed by bonding to the surface of the back. At this time, the natural veneer (2) sliced from the solid wood is produced in the form of a sheet and bonded to the plywood (4) or the like as a base material, the coating layer (1) is formed on the upper side is used as a floor covering material.

그런데, 이와 같이 표면재로서 천연무늬목을 사용하는 종래 마루바닥재는 무 늬목(2)이 비교적 고가일 뿐만 아니라 물체를 떨어뜨릴 경우 찍히거나 긁혀 표면의 무늬목(2)이 손상되는 문제가 있었다. 또한, 통상적으로 무늬목(2)과 합판등의 기재층(4)을 접착제(3)로 접합하게 되는데 이럴 경우 온도변화에 따라 무늬목(2)이 합판(4)에서 분리되는 경우가 간혹 발생하게 되는 문제가 있었다.However, the conventional floorboard material using natural veneer as a surface material as described above has a problem that the wood veneer (2) is not only relatively expensive, but also when the object is dropped, the veneer (2) of the surface is damaged by being photographed or scratched. In addition, the veneer (2) and the base material layer (4) such as plywood is usually bonded with an adhesive (3). In this case, the veneer (2) is sometimes separated from the plywood (4) due to temperature change. There was a problem.

따라서, 이와 같은 문제점을 해결하기 위해 표면강도를 강화시키기 위해 천연무늬목 대신 다양한 무늬가 인쇄된 모양지에 멜라민수지를 함침시킨 저압멜라민 함침지를 합판 상부에 열압하여 제조되는 마루바닥재가 개발되어 있다. 그러나, 이와 같이 합판 상부에 저압멜라민 함침지(LPM)를 열압하여 제조하는 경우에는 제조비용이 저렴한 장점은 있으나, 합판의 표면밀도가 불균일함으로 인하여 저압멜라민 함침지와의 접착력이 약하여 온도나 압력의 변화에 따라 떨어지는 문제점이 있었다. 또한, 이러한 문제점을 해결하기 위해 저압멜라민 함침지가 아닌 여러 장의 멜라민 함침지를 50kgf/㎠이상의 고압에서 열압하여 성형하는 고압멜라민 함침지(HPM)가 사용되기도 하나 고압멜라민 함침지의 경우 비교적 고가인 문제점이 있다.Therefore, in order to solve such problems, a flooring material is manufactured by thermopressing a low-pressure melamine impregnated paper impregnated with melamine resin on a pattern paper printed with various patterns instead of natural veneer to enhance surface strength. However, when the low pressure melamine impregnated paper (LPM) is manufactured by thermopressing the upper part of the plywood as described above, the manufacturing cost is advantageous. However, due to the non-uniformity of the surface density of the plywood, the adhesive strength with the low pressure melamine impregnated paper is weak. There was a problem falling with the change. In addition, to solve this problem, high pressure melamine impregnated paper (HPM), which is formed by hot-pressing several sheets of melamine impregnated paper at a high pressure of 50 kgf / cm 2 or more, is used in the case of high pressure melamine impregnated paper. .

그 다음 투명 보호필름(50)의 상면에 마루를 제조하는 일반공정인 UV도료로 UV도장층(60)을 형성한다.Next, a UV coating layer 60 is formed of UV coating, which is a general process of manufacturing floors, on the upper surface of the transparent protective film 50.

이상과 같이 본 발명에 따른 마루바닥재의 제조방법에 의하면, 중/고밀도 섬유판의 양측에 멜라민수지 함침 모양지와 오버레이지를 적층한 후 열압 압착한 다 음 중/고밀도 섬유판을 절단하여 제조함으로써, 한 번의 열압착으로 인해 2배수의 마루바닥재를 제조할 수 있어 제조시간과 제조공정이 단축되어 적은 제조비용으로 다량의 마루바닥재를 생산할 수 있는 장점이 있다. According to the manufacturing method of the flooring material according to the present invention as described above, by laminating the melamine resin impregnated pattern paper and the overlay paper on both sides of the medium / high density fiber board, and then by pressing and pressing to produce a medium / high density fiber board, Due to the thermocompression, it is possible to manufacture a double flooring material, which shortens the manufacturing time and manufacturing process, and thus has the advantage of producing a large amount of flooring material with a low manufacturing cost.

또한, 합판과 멜라민수지 함침 모양지(LPM)의 사이에 중/고밀도 섬유판을 개재하여 제조함으로써, 멜라민수지 함침 모양지와의 접착력이 우수해지고, 두꺼운 고가의 합판을 사용할 필요가 없어 제조비용이 저렴해지는 장점이 있다. In addition, by manufacturing a medium / high density fiberboard between the plywood and the melamine resin impregnated paper (LPM), the adhesive force with the melamine resin impregnated paper is excellent, and the manufacturing cost is low because there is no need to use a thick expensive plywood. There is an advantage to being terminated.
