Description

Method of adhering printing paper on plywood floor {Method for adhesiving the printing paper of plywood floor}

본 발명은 아파트나 주택 등의 거실바닥에 시공되어 장식되는 마루재에 관한 것으로, 특히 마루재의 주재료인 합판재와 인쇄지를 접착하여 제조단가 및 제조공수를 점감시킴과 더불어 내수성을 증대시킬 수 있도록 된 합판마루의 인쇄지 접착 방법에 관한 것이다.The present invention relates to a flooring that is installed and decorated on the floor of a living room such as an apartment or a house, and in particular, plywood, which is the main material of the flooring, is bonded to a printing paper to reduce the manufacturing cost and manufacturing labor and increase water resistance. A printing paper bonding method of floor.

일반적으로, 마루재는, 아파트나 주택 등의 거실이나 현관의 바닥면에 시공되어 목재의 질감을 느끼면서도 안락함을 제공하는 것으로서, 이러한 마루재로는 원목을 주재료로 하는 원목마루와 합판을 주재료로 하는 합판마루와 강화소재를 주재료로하는 강화마루 등으로 대별된다.In general, the flooring is installed in the floor of the living room or entrance of the apartment or house, providing comfort while feeling the texture of the wood. It is roughly divided into floors and reinforced floors based on reinforced materials.

그러나, 원목마루는, 목재 자체의 천연 질감을 살리면서도 고급스러운 장점이 있기는 하지만, 원목자체의 단가가 비쌀 뿐만 아니라 수축팽윤이 매우 심하여 대중화가 어려우며, 바닥난방이 주요 난방 방식인 국내의 현실을 감안하여 가정용으로 적용하기에는 미흡한 단점이 있다.However, solid wood flooring, while utilizing the natural texture of the wood itself, has the advantage of being luxurious, but not only the cost of the wood itself is expensive, but also the shrinkage and swelling is very difficult to popularize, and floor heating is the main heating method domestic realities In view of this, there is a disadvantage that it is insufficient to apply to the home.

그리고, 합판마루는, 합판에 천연무늬목을 건식공정을 통해 접착하고 우레탄 등과 같은 도장물질을 코팅한 다음 샌딩공정과 절단공정 및 홈파기가공을 통해 제조되는 마루재로서, 천연무늬목 자체의 단가가 비쌀 뿐만 아니라 제조공정이 복잡하여 가공비가 증대됨은 물론 내수성이 저하되는 문제점이 있었다.And, plywood floor is a flooring manufactured by bonding natural veneer to plywood through a dry process, coating a coating material such as urethane, and then by sanding process, cutting process, and grooving process. In addition, the manufacturing process is complicated, the processing cost is increased as well as there was a problem that the water resistance is lowered.

또한, 합판마루는, 합판에 천연무늬목을 접착하고 45°각도의 컷터날로 가공하는 이른바, 면도리작업을 수행하게 되므로, 면도리작업에 따른 작업하중 및 작업공수가 증대되어 제조단가가 증대될 뿐만 아니라 면도리부분으로 오염물질이 침투되어 제품을 조기에 손상시키는 문제점이 있었다.In addition, the plywood floor is a so-called shaving work to bond the natural veneer to the plywood to the cutting blade of 45 ° angle, so that the work load and workmanship according to the shaving work is increased to increase the manufacturing cost But there was a problem that the contaminants penetrate into the shaving portion and damage the product early.

한편, 강화마루는, 인조합판(HDF 소재)에 인쇄지를 함침하고 고온 및 고압의 압축과정을 통해 제조되는 마루재로서, 디자인이 다양함은 물론 유지관리가 양호한 장점이 있기는 하지만, 목재자체의 천연질감을 낼 수 없을 뿐만 아니라 습기에 민감하여 내수성이 저하되는 문제점이 있었다.On the other hand, reinforced floor is a flooring material which is manufactured by impregnating printing paper on HDF material and compressing it at high temperature and high pressure, and it has various advantages in design and good maintenance. Not only can not texture, but also sensitive to moisture there was a problem that the water resistance is lowered.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 합판마루에 접착되는 천연무늬목을 대신하여 인쇄지를 부착하여 마루재의 제조단가 및 작업공수를 절감시킴과 더불어 내수성을 증대시킬 수 있도록 된 합판마루의 인쇄지 접착 방법을 제공하는 데에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the problems as described above, by attaching printing paper in place of the natural veneer glued to the plywood floor to reduce the manufacturing cost and labor of the flooring material and increase the water resistance. It is an object of the present invention to provide a method of adhering printing paper to plywood floors.

상기한 바의 목적을 달성하기 위한 인쇄지의 접착 방법은, 합판상에 50∼100g/㎡의 두께로 접착제를 도포한 상태에서, 이 접착제의 상부측에 인쇄지 두 장을 겹쳐서 안착시킨 다음, 110∼130℃의 온도가 유지되는 핫프레스를 이용하여 100∼150 ㎏/㎤의 압력에서 0.5∼2분 동안 압축한 후, 상온에서 2∼4시간 동안 자연 냉각시키는 것을 특징으로 한다.The method of adhering printing paper for achieving the above object is to laminate two sheets of printing paper on the upper side of the adhesive with the adhesive applied to the plywood at a thickness of 50 to 100 g / m 2, then 110 After compressing for 0.5 to 2 minutes at a pressure of 100 to 150 kg / cm 3 using a hot press maintained at a temperature of ˜130 ° C., it is naturally cooled at room temperature for 2 to 4 hours.

그리고, 상기 합판상에 도포되는 접착제로는, 멜라민 50∼60wt％ - 라텍스 20∼30wt％ - 전분 10∼20wt％ - 경화제 0.1∼0.5wt％가 배합되는 성분을 갖는 것을 특징으로 한다.And as an adhesive agent apply | coated on the said plywood, it has a component which 50-60 wt% of melamine-20-30 wt% of latex-10-20 wt% of starch-0.1-0.5 wt% of a hardening | curing agent are mix | blended.

이하, 본 발명의 인쇄지의 접착 방법을 설명하면 다음과 같다.Hereinafter, the adhesive method of the printing paper of the present invention will be described.

먼저, 본 발명의 접착제로는, 합판마루의 내수성과 내열성을 감안하여 배합되는 조성비로서, 실내장식용 가구에 통상적으로 사용하는 요소수지나 폴리졸을 대신하여, 상기한 성분을 갖는 접착제를 도포한 것이다.First, the adhesive of the present invention is a composition ratio blended in consideration of the water resistance and heat resistance of the plywood floor, and is applied to the adhesive having the above-mentioned components in place of urea resins and polysols commonly used in upholstery furniture. .

이때, 경화제로는, 염화암모늄 등과 같이 경화속도가 비교적 빠르면서 경화효율이 높을 재료를 사용함이 바람직하다.In this case, as the curing agent, it is preferable to use a material having a high curing efficiency while having a relatively high curing rate such as ammonium chloride.

이어서, 인쇄지의 절단작업에서 즉, 합판의 무늬결방향으로 940mm, 무늬결반대방향으로 925mm의 면적으로 절단하되, 이렇게 절단된 인쇄지 두 장을 나란히 이어 붙여서 사용함이 바람직하다.Subsequently, in the cutting operation of the printing paper, that is, cutting the area of 940 mm in the patterned direction of the plywood and 925 mm in the opposite direction of the patterned pattern, it is preferable to use two sheets of the printed paper thus connected side by side.

그런 다음, 스프레더장치(미도시)의 롤러위에 접착제를 공급하면서, 스프레더장치를 작동하여 롤러사이로 합판(910 ×1820mm)을 통과시켜, 합판의 상부측에50∼100g/㎡의 두께로 접착제를 도포하였다.Then, while supplying the adhesive on the roller of the spreader device (not shown), the spreader device is operated to pass the plywood (910 x 1820 mm) between the rollers, and the adhesive is applied to the upper side of the plywood with a thickness of 50 to 100 g / m 2. It was.

이어서, 접착제의 상부측에, 합판의 90°방향인 가로방향으로 인쇄지 두장을 이어 붙였으며, 이때, 인쇄지의 겹침부위를 1mm이하로 유지하였다. 물론, 인쇄지를 합판 보다 크게 절단하여 예컨대, 도장과정에서 합판의 측면으로 도료가 흐르는 것을 방지함이 바람직하다.Subsequently, two sheets of printing paper were attached to the upper side of the adhesive in the transverse direction in the 90 ° direction of the plywood, and at this time, the overlapped portion of the printing paper was kept at 1 mm or less. Of course, it is preferable to cut the printing paper larger than the plywood, for example, to prevent paint from flowing to the side of the plywood during the painting process.

그런 다음, 핫프레스(미도시, 110∼130℃)를 이용하여 인쇄지의 상부면을 100∼150㎏/㎤의 압력에서 0.5∼2분 동안 압축한 다음, 핫프레스에서 인쇄지가 접착된 합판(이하, 접착소재라 칭함)을 인출하였다.Then, using a hot press (not shown, 110 to 130 ° C.), the upper surface of the printing paper was compressed at a pressure of 100 to 150 kg / cm 3 for 0.5 to 2 minutes, and then the plywood to which the printing paper was bonded in the hot press (hereinafter referred to as , Called an adhesive material).

이어서, 접착소재를 상온상태에서 2∼4시간 동안 자연건조시키면서 냉각시킨 결과, 합판의 상부측에 인쇄지 두 장이 나란히 부착된 상태로 유지되었다.Subsequently, the adhesive material was cooled while naturally drying at room temperature for 2 to 4 hours. As a result, two sheets of printing paper were attached to the upper side of the plywood side by side.

이때, 인쇄지는, 폴리에스테르 필름의 인쇄문양의 흡수를 용이하게 하는 티타늄이 미량 포함됨과 더불어 폴리에스테르 수지의 함침을 위한 유성 또는 수성물질이 포함됨은 당연하다.At this time, the printing paper is included in the trace amount of titanium, which facilitates the absorption of the print pattern of the polyester film, as well as oil or water for impregnating the polyester resin is naturally included.

이상에서 설명한 바와 같이 본 발명에 따른 합판마루의 인쇄지 접착 방법에 의하면, 합판재에 인쇄지를 접착하여 합판마루로 제조하므로 천연무늬목을 사용하는 종래 방식에 비해 제조단가 및 제조공수가 절감되어 합판마루의 제조에 따른 각종 부대비용이 절감되는 효과가 있다.As described above, according to the printing paper adhering method of plywood floor according to the present invention, the printing paper is adhered to the plywood material and manufactured as plywood floor, thereby reducing the manufacturing cost and manufacturing labor compared to the conventional method using natural veneer. There is an effect of reducing the various incident costs according to the manufacturing.
