종래의 천연마루는 합판구조에 접착제 층을 형성하고 위에 무늬목을 입히고 표면도장층을 형성한 마루이다. 이러한 천연마루는 사용하는 무늬목 자체가 온도, 습도 조절작용, 삼림욕 효과, 전기파장 억제기능, 방사능 방어기능 등으로 쾌적함을 제공하여 건강 측면에서 긍정적 기능을 하지만, 다른 재료에 비해 강도가 약하여 사용상 찍힘, 눌림, 긁힘 등에 약한 단점을 갖고 있다. 또한, 무늬목은 수분을 흡수하여 변색되거나 변형이 되는 성질이 있는 단점도 있다.Conventional natural floors are floors formed by forming an adhesive layer on a plywood structure, coating veneer thereon, and forming a surface coating layer. These natural floorings provide comfort in terms of temperature, humidity control, forest bathing effect, electric wave suppression, and radiological defense function, but have a positive function in terms of health, but they are weak in strength compared to other materials. It has a weak point of being pressed, scratched, etc. In addition, veneer has a disadvantage in that it absorbs moisture and discolors or deforms.

이 같은 단점으로 인하여 사용자들이 바닥재를 사용할 때 부주의로 인하여 생활도구를 떨어뜨리거나, 무거운 물건을 이동할 때 바닥재 표면에 손상이 발생할 수 있다. Due to this drawback, when the user uses the flooring, carelessness may cause damage to the surface of the flooring material when the household utensil is dropped or a heavy object is moved.

이에 본 발명자들은 종래 천연마루의 단점을 해결하기 위해 연구와 실험을 거듭하여 본 발명을 제안하게 된 것으로, 본 발명은 천연마루의 외관을 유지하면서 수분에 의한 변색 및 변형을 억제하고, 외부충격에 의한 저항성을 향상시킨 표면이 강한 표면강화 천연마루 바닥재 및 그 제조방법을 각각 제공하고자 하는데, 그 목적이 있다.In order to solve the shortcomings of the conventional natural floor, the present inventors have repeatedly proposed research and experiment, and the present invention, while maintaining the appearance of the natural floor, suppresses discoloration and deformation caused by moisture and prevents external impact. The purpose of the present invention is to provide a surface-reinforced natural hardwood flooring and a method of manufacturing the same, each of which has improved surface resistance.

이하, 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.

본 발명의 천연마루 바닥재는 위로부터 순차적으로 적층된 표면도장층, 오버레이 (Overlay)층, 무늬목층, 유리섬유 (Glass Fiber) 함침층, 및 합판 (Plywood)층을 포함하여 이루어진다.The natural flooring material of the present invention comprises a surface coating layer, an overlay (Overlay) layer, a veneer layer, a glass fiber impregnated layer, and a plywood layer laminated sequentially from above.

상기 합판층, 무늬목층은 기존에 공지된 방법이나 재료에 의해 시공할 수 있다.The plywood layer, veneer layer can be constructed by a conventionally known method or material.

상기 유리섬유 함침층은 페놀수지, 멜라민수지로부터 선택된 수지에 유리섬유지를 함침하여 형성하는 것으로, 보강층의 역할을 하여 찍힘이나 눌림에 대한 저항성을 향상시키고, 열압 프레스 공정에 의한 압밀화에 의해서 무늬목층에 수지 성분을 공급하여 수분에 의한 무늬목의 변색/변형을 억제할 수 있는 것이다. 이때 사용할 수 있는 유리섬유는 평량 80 내지 300 g/m2의 유리섬유이며, 페놀수지, 멜라민 수지로부터 선택된 수지에 유리섬유지 평량 대비 30 내지 150 중량%를 함침시킨 후 80 내지 150 ℃ 오븐에서 0.5 내지 3 분간 건조 및 반경화시켜 조제하였다. 상기 유리섬유 함침지는 원하는 두께에 따라서 여러 장을 사용할 수도 있다.
The glass fiber impregnated layer is formed by impregnating glass fiber paper in a resin selected from phenol resin and melamine resin, and serves as a reinforcing layer to improve resistance to chipping or crushing, and to obtain a pattern wood layer by consolidation by a hot pressing process. It is possible to suppress discoloration / deformation of veneer by water by supplying a resin component to the resin. At this time, the glass fiber that can be used is a glass fiber of 80 to 300 g / m 2 basis weight, impregnated 30 to 150% by weight relative to the basis weight of glass fiber paper in a resin selected from phenolic resin, melamine resin 0.5 in 80 to 150 ℃ oven Prepared by drying and semi-curing for 2-3 minutes. The glass fiber impregnated paper may use several sheets depending on the desired thickness.

상기 오버레이층은 멜라민 수지에 셀룰로오스지를 함침하여 형성하는 것으로, 무늬목의 낮은 비중에 의한 눌림, 찍힘, 긁힘에 대한 저항성을 향상시키고, 열압 프레스 공정에 의한 압밀화에 의해서 무늬목층에 수지성분을 공급하여 수분에 의한 무늬목의 변색/변형을 억제할 수 있는 것이다. 이때 사용할 수 있는 셀룰로오스지는 평량 20 내지 100 g/m2의 셀룰로오스지이며, 셀룰로오스지에 내마모 실리카 또는 알루미나가 고르게 분포되어 함유된 오버레이지를 오버레이지 평량 대비 150 내지 300 중량%의 멜라민 수지로 함침시킨 후 100 내지 150 ℃ 오븐에서 0.5 내지 4 분간 건조 및 반경화시켜 조제하였다.
The overlay layer is formed by impregnating cellulose paper with melamine resin, and improves resistance to crushing, chipping, and scratching due to low specific gravity of the veneer, and supplies a resin component to the veneer layer by consolidation by a hot pressing process. Discoloration / deformation of veneer due to moisture can be suppressed. At this time, the cellulose paper which can be used is a cellulose paper having a basis weight of 20 to 100 g / m 2 , and the overlay paper containing abrasion-resistant silica or alumina evenly distributed in the cellulose paper is impregnated with a melamine resin of 150 to 300% by weight relative to the basis weight of the overlay paper. Prepared by drying and semi-curing for 0.5 to 4 minutes in a 100 to 150 ℃ oven.

상기 표면도장층은 순차적으로 적층된 표면 프라이머층, 하도층, 중도층 및 상도층을 포함한다.The surface coating layer includes a surface primer layer, a lower layer, a middle layer, and a top coat layer sequentially stacked.

본 발명의 바닥재는 합판층, 유리섬유 함침층, 무늬목층, 오버레이층을 열압프레스 (Hot Press)에서 고온, 고압 조건으로 일체화시키는 것이 바람직하다. 열압프레스 가공시 하부의 유리섬유 함침층과 상부의 오버레이층의 수지성분이 무늬목 내부로 보다 많이 침투되어, 침투된 수지성분이 경화됨으로써 수분에 의한 변색/변형을 우수하게 억제할 수 있기 때문이다. 또한, 유리섬유 함침지와 오버레이 함침지가 고온, 고압에서 완전 경화됨으로써 합판층, 유리섬유 함침층, 무늬목층, 오버레이층 간의 층간 접착력이 접착제 없이도 강한 접착력을 가질 수 있다.
In the flooring material of the present invention, it is preferable to integrate the plywood layer, glass fiber impregnation layer, veneer layer, and overlay layer under high temperature and high pressure conditions in a hot press. This is because the resin component of the glass fiber impregnated layer and the overlay layer on the upper side is more penetrated into the veneer at the time of hot pressing, and thus the discolored / deformed due to moisture can be excellently suppressed by curing the penetrated resin component. In addition, since the glass fiber impregnated paper and the overlay impregnated paper are completely cured at high temperature and high pressure, the interlayer adhesion between the plywood layer, the glass fiber impregnated layer, the veneer layer, and the overlay layer may have a strong adhesive force without an adhesive.

상기한 바와 같은 층 구조를 갖는 본 발명의 바닥재 제조방법 중에서 대표적인 방법은 다음과 같다. Representative methods of the flooring manufacturing method of the present invention having a layer structure as described above are as follows.

먼저, 페놀수지, 멜라민 수지로부터 선택된 수지에 평량 80 내지 300 g/m2의 유리섬유지를 평량 대비 30 내지 150 중량%로 함침시킨 후 80 내지 150 ℃ 오븐에서 0.5 내지 3분간 건조 및 반경화시켜 유리섬유 함침지를 제조하고, 평량 20 내지 100 g/m2 셀룰로오스지에 내마모 실리카 또는 알루미나가 고르게 분포되어 함유된 오버레이지를 오버레이지 평량 대비 150 내지 300 중량%의 멜라민 수지로 함침시킨 후, 100 내지 150 ℃ 오븐에서 0.5 내지 4 분간 건조 및 반경화시켜 오버레이 함침지를 제조하는 과정을 거친다. First, a glass fiber paper having a basis weight of 80 to 300 g / m 2 is impregnated in a resin selected from a phenol resin and melamine resin at 30 to 150% by weight, and then dried and semi-cured in an oven at 80 to 150 ° C. for 0.5 to 3 minutes. Fiber impregnated paper was prepared, and the overlay paper containing abrasion-resistant silica or alumina evenly distributed in a basis weight of 20 to 100 g / m 2 cellulose paper was impregnated with 150 to 300% by weight of melamine resin relative to the basis weight of overlay paper, and then 100 to 150 ° C. Drying and semi-curing in an oven for 0.5 to 4 minutes to produce an overlay impregnated paper.

그리고 합판 상에 상기 유리섬유 함침지를 위치시키고, 그 위에 무늬목을 위치시키고, 그 위에 상기 오버레이 함침지를 위치시킨 후, 열압 프레스에 의해 일체화시키는 과정을 거친다.
Then, the glass fiber impregnated paper is placed on the plywood, the veneer is placed thereon, the overlay impregnated paper is placed thereon, and then integrated by a hot press.

그리고, 상기 함침 페이퍼 위에 표면도장층을 형성시키고 재단 및 형상 가공하는 과정을 거친다. Then, the surface coating layer is formed on the impregnated paper, and undergoes cutting and shape processing.

상기 열압 프레스 공정은 130 내지 190 ℃의 온도에서 100 내지 150 kg/cm2의 압력으로 5 내지 10분간 가열 및 가압을 실시한다. 온도가 130 ℃미만이면 오버레이 함침지와 유리섬유 함침지의 미경화에 의해 층간 접착의 박리 문제가 발생할 수 있으며, 온도가 190 ℃를 초ㅘ하면 무늬목의 열에 의한 변색이 발생할 수 있다. The hot press process is heated and pressurized for 5 to 10 minutes at a pressure of 100 to 150 kg / cm 2 at a temperature of 130 to 190 ℃. If the temperature is less than 130 ℃ may cause the problem of peeling of the interlayer adhesion due to the uncuring of the overlay impregnated paper and glass fiber impregnated paper, if the temperature is 190 ℃ may cause discoloration by heat of veneer.

또한, 압력이 100 kg/cm2 미만이면 무늬목에 대한 수지 침투량이 감소하여 수분에 의한 변색/변형의 억제 기능이 감소할 수 있으며, 압력이 150 kg/cm2 초과하면 고압에 의한 합판 및 제품의 두께 감소 및 합판의 터짐이 발생할 수 있다. In addition, if the pressure is less than 100 kg / cm 2 , the amount of resin penetrating into the veneer may be reduced to reduce the discoloration / deformation by moisture, and when the pressure exceeds 150 kg / cm 2 of the plywood and products Reduced thickness and bursting of the plywood may occur.

한편, 시간이 5 분 미만이면 오버레이 함침지와 유리섬유 함침지의 미경화에 의해 층간 접착의 박리 문제가 발생할 수 있으며, 시간이 10 분 이상이면 무늬목의 열에 의한 변색이 발생할 수 있다.
On the other hand, when the time is less than 5 minutes, the problem of peeling of the interlayer adhesion may occur due to the uncuring of the overlay impregnated paper and the glass fiber impregnated paper, and when the time is 10 minutes or more, discoloration may occur due to heat of veneer.

각 층별 두께는 표면도장층은 롤 코터를 이용하여 0.08 내지 0.1 mm, 오버레이층은 0.1 내지 0.2 mm, 무늬목층은 0.3 내지 0.6 mm, 유리섬유 함침층은 0.2 내지 0.4 mm, 합판층은 0.7 내지 0.75 mm가 바람직하다.
The thickness of each layer is 0.08 to 0.1 mm for the surface coating layer using a roll coater, 0.1 to 0.2 mm for the overlay layer, 0.3 to 0.6 mm for the veneer layer, 0.2 to 0.4 mm for the glass fiber impregnation layer, and 0.7 to 0.75 for the plywood layer. mm is preferred.

상술한 바에 따르면, 천연마루의 외관을 유지하면서 수분에 의한 변색/변형이 없고 표면이 강한 천연마루를 제공할 수 있다. 이때 표면 강화는 하기 실시 예를 통하여 규명된 바와 같이, 유리섬유 함침층이 보강층의 역할을 하여 찍힘이나 눌림에 대한 저항성을 향상시키고, 오버레이(Overlay)층이 무늬목의 낮은 비중에 의한 눌림,찍힘, 긁힘에 대한 저항성을 향상시키며, 오버레이 (Overlay)층과 표면도장층에 의해 외부의 긁힘에 대한 표면 물성이 강화되기 때문으로 여겨진다. According to the above, it is possible to provide a natural floor with no surface discoloration / deformation due to moisture while maintaining the appearance of the natural floor. At this time, as the surface reinforcement is identified through the following examples, the glass fiber impregnated layer acts as a reinforcing layer to improve resistance to being taken or pressed, and the overlay layer is pressed, peeled, It is considered to improve the resistance to scratches, and the surface properties against external scratches are enhanced by the overlay layer and the surface coating layer.

나아가 내수성 강화는 무늬목 자체는 수분을 흡수하여 변색/변형이 되는 성질을 갖고 있으나, 본 발명에 의한 제조시 핫 프레스에 의해 하부의 유리섬유 함침층과 상부의 오버레이 (Overlay)층의 수지 성분이 무늬목 내부로 침투되어 경화됨으로써 수분에 의한 변색/변형을 방지하기 때문으로 여겨진다. Furthermore, the water resistance reinforcement has the property that the veneer itself absorbs moisture and discolors / deforms, but the resin component of the glass fiber impregnated layer and the overlay layer on the upper side is produced by the hot press during manufacture according to the present invention. It is considered to be because it prevents discoloration / deformation due to moisture by penetrating and curing inside.

본 발명에 의하면, 유리섬유 함침층과 오버레이층이 찍힘이나 눌림에 대한 저항성을 향상시키고, 유리섬유 함침층과 오버레이층의 수지성분이 무늬목 내부로 침투되어 경화됨으로써 수분에 의한 변색/변형을 방지할 수 있는 효과가 있다.According to the present invention, the glass fiber impregnation layer and the overlay layer improve the resistance to the stamping or pressing, and the resin components of the glass fiber impregnation layer and the overlay layer penetrate into the veneer and harden to prevent discoloration / deformation due to moisture. It can be effective.

상기한 바와 같은 방법에 의해 제조된 3 종류의 바닥재에 대하여 온돌마루 표면강도 측정법에 따라 상온에서 일정 크기의 시편을 재단한 후 긁힘 (내스크래치성)은 다이아몬드 침범을 이용하여 0.5 N 단위로 측정하였으며, 찍힘 (내충격성)의 경우 286 g의 추를 이용하여 10 cm 단위로 자유 낙하시켜 표면의 손상 유무를 육안으로 판정하여 측정하였으며, 눌림 (내캐스터성)의 경우 속도 12 m/min, 중량 60 kg, 반복회수 100 회로 하여 표면의 눌림 정도를 다이얼 게이지를 사용하여 측정하였다. After cutting the specimen of a certain size at room temperature according to the ondol floor surface strength measurement method for the three types of flooring materials prepared by the method described above, the scratch (scratch resistance) was measured in 0.5 N units using diamond invasion. In the case of stamping (impact resistance), a free fall of 10 cm was carried out using a 286 g weight to determine whether the surface was damaged or not. The degree of pressing of the surface was measured by using a dial gauge with 100 kg and a repeated number of times.

표 1에서 보듯이, 본 발명의 바닥재는 기존의 바닥재 대비 긁힘 (내스크래치성), 찍힘 (내충격성) 및 눌림 (내캐스터성)에 대한 저항성이 우수함을 알 수 있었다.
As shown in Table 1, the flooring of the present invention was found to have excellent resistance to scratching (scratch resistance), stamping (impact resistance) and crushing (caster resistance) compared to the conventional flooring.

이 같은 표면 강화는 유리섬유 함침층이 보강층의 역할을 하여 찍힘이나 눌림에 대한 저항성을 향상시키고, 오버레이 (Overlay)층이 무늬목의 낮은 비중에 의한 눌림, 찍힘, 긁힘에 대한 저항성을 향상시키며, 오버레이 (Overlay)층과 표면도장층에 의해 외부의 긁힘에 대한 표면 물성이 강화되기 때문으로 여겨진다.
This surface reinforcement allows the glass fiber impregnated layer to act as a reinforcing layer to improve resistance to chipping or crushing, while the overlay layer improves resistance to crushing, chipping and scratching due to low specific gravity of the veneer. It is considered that the surface properties against external scratches are strengthened by the overlay layer and the surface coating layer.

표 2에서 보는 바와 같이, 본 발명에 의한 바닥재는 기존의 바닥재에 비하여 수분에 대한 저항성이 우수하여 변색 및 변형이 잘 되지 않음을 알 수 있었으며, 이 같은 내수성 강화는 무늬목 자체는 수분을 흡수하여 변색/변형되는 성질을 갖고 있으나, 본 발명에 의한 제조시 핫 프레스에 의해 하부의 유리섬유 함침층과 상부의 오버레이 (Overlay)층의 수지 성분이 무늬목 내부로 침투되어 경화됨으로써 수분에 의한 변색/변형을 방지하기 때문으로 여겨진다. As shown in Table 2, the flooring according to the present invention was excellent in resistance to moisture compared to the existing flooring, it was found that the discoloration and deformation is not good, this water-resistant reinforcement, the veneer itself absorbs the water discoloration Although it has the property of being deformed, the resin component of the glass fiber impregnation layer and the overlay layer of the upper layer is penetrated into the veneer and cured by the hot press during the production according to the present invention to prevent discoloration / deformation due to moisture. It is believed to prevent.
