Description

코르크층을 포함하는 쿠션 바닥재{CUSHION FLOOR TILE HAVING CORK LAYER}Cushion flooring material including a cork layer {CUSHION FLOOR TILE HAVING CORK LAYER}

본 발명은 마루 바닥재에 관한 것으로서, 보다 상세하게는 쿠션, 방음 등의 기능을 부여하기 위해 코르크층을 포함하는 쿠션 바닥재에 관한 것이다.The present invention relates to parquet flooring, and more specifically, to a cushion flooring material including a cork layer to provide cushioning, soundproofing, etc. functions.

목재를 주요 소재로 하는 종래의 마루 바닥재는 층간소음 저감을 위해 코르크층을 포함하게 되었다.Conventional flooring materials mainly made of wood include a cork layer to reduce noise between floors.

예를 들어, 도 1에 도시된 바와 같이 목재로 이루어진 본체(30)의 상면에 표면패널(40)과 코팅층(50)을 구비하고, 상기 본체(30)의 저면에 코르크 패널(60)을 형성함으로써 이의 탄성을 이용하여 충격을 완충시키고 소음을 저감시키는 효과를 얻도록 하였다.For example, as shown in Figure 1, a surface panel 40 and a coating layer 50 are provided on the upper surface of a main body 30 made of wood, and a cork panel 60 is formed on the bottom of the main body 30. By doing so, the effect of cushioning shock and reducing noise was obtained by using its elasticity.

그러나, 이와 같은 종래의 마루 바닥재는 코르크 패널(60)이 본체(30)에 부착하기 위해 도포하는 접착제가 대부분 상기 코르크 패널(60) 속으로 흡수됨에 따라 많은 양의 접착제를 도포하여야만 상기 본체(30)에 부착될 수 있었는데, 이 경우 많은 양의 접착제가 함유되어 경화한 코르크 패널(60)은 쿠션 기능이 현저히 떨어지고, 방음 효과도 달성하지 못한다는 문제가 있었다.However, in such a conventional flooring material, most of the adhesive applied to attach the cork panel 60 to the main body 30 is absorbed into the cork panel 60, so a large amount of adhesive must be applied to attach the cork panel 60 to the main body 30. ), but in this case, the cork panel 60 cured with a large amount of adhesive had a problem in that the cushioning function was significantly reduced and the soundproofing effect was not achieved.

따라서, 본 발명의 목적은 코르크층의 성능저하 없이도 목재로 이루어진 본체에 부착시킬 수 있는 쿠션 바닥재를 제공하는 데 있다.Therefore, the purpose of the present invention is to provide a cushion flooring material that can be attached to a body made of wood without deteriorating the performance of the cork layer.

상기 목적을 달성하기 위해 본 발명은 코르크층을 포함하는 쿠션 바닥재에 있어서, 오버레이(overlay)와, 모양지와, 밀도가 400~450kg/㎥이고 두께가 1~1.2mm인 코르크층이 적층되어 일체화됨으로써 얻어지는 고압수지함침시트(High Pressure Laminate, HPL)와; 접착제층과; 합판 내지 목재로 이루어진 본체를 포함하며, 상,하 금형 사이에 상기 고압수지함침시트, 상기 접착제층 및 상기 본체를 적층하여 개재시킨 상태에서 상기 상,하 금형을 통해 가압함으로써 상기 코르크층과 상기 본체가 부착되도록 한 것을 특징으로 하는 코르크층을 포함하는 쿠션 바닥재를 제공한다.In order to achieve the above object, the present invention provides a cushion flooring material including a cork layer, in which an overlay, a patterned paper, and a cork layer with a density of 400 to 450 kg/㎥ and a thickness of 1 to 1.2 mm are laminated and integrated. A high pressure resin impregnated sheet (High Pressure Laminate, HPL) obtained by becoming; an adhesive layer; It includes a main body made of plywood or wood, and the high-pressure resin impregnated sheet, the adhesive layer, and the main body are laminated and interposed between the upper and lower molds, and the cork layer and the main body are pressed through the upper and lower molds. Provides a cushion flooring material including a cork layer, characterized in that it is attached.

여기서, 상기 쿠션 바닥재는 핫멜트 시트로 이루어진 핫멜트층과; 밀도가 400~450kg/㎥이고 두께가 1~1.2mm인 제2 코르크층을 더 포함하며, 상기 상,하 금형 사이에는 상기 고압수지함침시트, 상기 접착제층 및 상기 본체에 더하여 상기 제2 핫멜트층과 상기 제2 코르크층을 적층하여 개재시킨 상태에서 상기 상,하 금형을 통해 가열 및 가압함으로써 상기 핫멜트층에 열전달을 시켜 이를 매개로 하여 상기 본체에 상기 제2 코르크층이 부착되도록 할 수도 있다.Here, the cushion flooring material includes a hot melt layer made of a hot melt sheet; It further includes a second cork layer having a density of 400 to 450 kg/㎥ and a thickness of 1 to 1.2 mm, and between the upper and lower molds is a second hot melt layer in addition to the high pressure resin impregnated sheet, the adhesive layer, and the main body. and the second cork layer are stacked and sandwiched, and the heat is transferred to the hot melt layer by heating and pressing through the upper and lower molds, thereby allowing the second cork layer to be attached to the main body.

또한, 상기 목적을 달성하기 위해 본 발명은 코르크층을 포함하는 쿠션 바닥재에 있어서, 오버레이(overlay)와, 모양지와, 크라프트지가 적층되어 일체화됨으로써 얻어지는 고압수지함침시트(High Pressure Laminate, HPL)와; 상기 고압수지함침시트의 저면에 부착되어 일체화되는, 합판 내지 목재로 이루어진 본체와; 핫멜트 시트로 이루어진 핫멜트층과; 밀도가 400~450kg/㎥이고 두께가 1~1.2mm인 코르크층을 포함하며, 상,하 금형 사이에 상기 고압수지함침시트에 일체화된 본체, 상기 핫멜트층 및 상기 코르크층을 적층하여 개재시킨 상태에서 상기 상,하 금형을 통해 가열 및 가압함으로써 상기 핫멜트층에 열전달을 시켜 이를 매개로 하여 상기 본체와 상기 코르크층이 부착되도록 한 것을 특징으로 하는 코르크층을 포함하는 쿠션 바닥재를 제공한다.In addition, in order to achieve the above object, the present invention provides a cushion flooring material including a cork layer, a high pressure resin impregnated sheet (High Pressure Laminate, HPL) obtained by stacking and integrating an overlay, patterned paper, and kraft paper, and ; a body made of plywood or wood that is attached to and integrated with the bottom of the high-pressure resin impregnated sheet; A hot melt layer made of a hot melt sheet; It includes a cork layer with a density of 400 to 450 kg/㎥ and a thickness of 1 to 1.2 mm, and the main body integrated with the high pressure resin impregnated sheet, the hot melt layer, and the cork layer are stacked and interposed between the upper and lower molds. Provides a cushion flooring material including a cork layer, wherein heat is transferred to the hot melt layer by heating and pressing through the upper and lower molds, and the main body and the cork layer are attached through this.

한편, 상기 코르크층은 코르크의 파쇄입자를 방수코팅한 것을 시트 형태로 압착함으로써 얻어진 것일 수도 있다.Meanwhile, the cork layer may be obtained by compressing crushed cork particles with a waterproof coating into a sheet form.

그리고, 상기 고압수지함침시트의 표면에는 멜라민 95중량% 및 은나노 5중량%를 함유하는 항균 코팅제가 도포되어 경화될 수도 있다.Additionally, an antibacterial coating containing 95% by weight of melamine and 5% by weight of silver nano may be applied to the surface of the high-pressure resin impregnated sheet and cured.

이상과 같이, 본 발명에 따른 쿠션 바닥재에 의하면 밀도가 400~450kg/㎥인 고밀도 코르크층을 이용함으로써 접착제가 흡수되는 현상을 상당 부분 차단할 수 있으므로 쿠션 및 방음 기능이 떨어지는 현상을 방지할 수 있다.As described above, according to the cushion flooring material according to the present invention, by using a high-density cork layer with a density of 400 to 450 kg / ㎥, absorption of adhesive can be blocked to a large extent, thereby preventing deterioration of cushion and soundproofing functions.

또한, 상기 코르크층의 두께를 1~1.2mm로 설정함으로써 이를 통한 열전달 저하 문제를 해결할 수 있으므로 핫멜트 시트를 매개로 하여 본체에 부착시키는 방법을 적용할 수 있다. 즉, 상,하 금형 사이에 개재하여 가열 및 가압 시 상기 핫멜트 시트로 충분한 열전달이 가능하므로 이를 매개로 한 코르크층과 본체의 부착이 가능하다. 이로써 접착제가 코르크층에 흡수되어 성능이 떨어지는 현상을 완전히 배제할 수 있다.In addition, by setting the thickness of the cork layer to 1 to 1.2 mm, the problem of reduced heat transfer through this can be solved, so a method of attaching it to the main body through a hot melt sheet can be applied. In other words, sufficient heat transfer is possible to the hot melt sheet when heated and pressed between the upper and lower molds, so it is possible to attach the cork layer and the main body through this. This completely eliminates the phenomenon of adhesive being absorbed into the cork layer and deteriorating performance.

도 7 내지 도 9는 본 발명의 제1 실시예에 따른 쿠션 바닥재의 제조과정을 설명하기 위한 단계별 단면도이다.1 is a cross-sectional view of a cushion flooring material according to the prior art;
2 to 4 are step-by-step cross-sectional views for explaining the manufacturing process of the cushion flooring material according to the first embodiment of the present invention;
Figures 5 and 6 are step-by-step cross-sectional views for explaining the manufacturing process of the cushion flooring material according to the second embodiment of the present invention;
7 to 9 are step-by-step cross-sectional views for explaining the manufacturing process of the cushion flooring material according to the first embodiment of the present invention.

본 발명의 제1 실시예에 따른 쿠션 바닥재(100)는 도 2 내지 도 4에 도시된 바와 같은 순서로 제조된다. 먼저, 도 2에 도시된 바와 같이 오버레이(Overlay, 111), 모양지(112) 및 코르크층(113)을 상하로 적층, 부착시켜 서로 일체함으로써 고압수지함침시트(High Pressure Laminate, HPL: 110)를 제조한다.The cushion flooring 100 according to the first embodiment of the present invention is manufactured in the order shown in FIGS. 2 to 4. First, as shown in Figure 2, the overlay (111), pattern paper (112), and cork layer (113) are stacked and attached top and bottom to form a high pressure resin impregnated sheet (High Pressure Laminate, HPL: 110). manufactures.

여기서, 코르크층(113)은 밀도가 450kg/㎥인 고밀도 코르크 시트로 이루어지며, 두께는 1.2mm인 것으로 한다. 상기 종래기술에 개시된 바와 같은 저밀도 코르크 시트와 달리 고밀도 코르크 시트는 표면에 도포되는 접착제가 내부로 용이하게 침투되는 현상을 억제할 수 있으며, 그 두께 또한 종래 2mm 이상이던 것을 1.2mm로 줄일 수 있어 충격완충과 소음저감의 효과를 보유하면서도 두께방향으로의 열전달 효율을 크게 저하시키지 않을 수 있다. 이로써 후술하는 바와 같이 핫멜트 시트를 매개로 하여 본체에 부착시키고자 할 경우 코르크층을 통해 상기 핫멜트 시트로 충분한 열을 전달할 수 있으므로, 종래 적용하지 못하던 핫멜트 시트를 통한 접착도 가능해진다.Here, the cork layer 113 is made of a high-density cork sheet with a density of 450 kg/m3 and has a thickness of 1.2 mm. Unlike the low-density cork sheet as disclosed in the prior art, the high-density cork sheet can prevent the adhesive applied to the surface from easily penetrating into the interior, and its thickness can also be reduced from 2mm or more to 1.2mm, reducing impact. While maintaining the effects of buffering and noise reduction, the heat transfer efficiency in the thickness direction cannot be significantly reduced. As a result, as will be described later, when attempting to attach to the main body via a hot melt sheet, sufficient heat can be transferred to the hot melt sheet through the cork layer, making adhesion through a hot melt sheet possible, which was not possible in the past.

나아가, 접착체의 침투를 방지함은 물론 설치 후 수분이 침투하는 현상을 예방하기 위해 상기 코르크층(113)을 이루는 개개의 코르크 입자에 대하여 방수코팅을 수행할 수 있다. 즉, 코르크 시트의 제조과정에서 코르크 목재를 파쇄하여 얻어지는 파쇄입자에 대하여 방수코팅을 수행하고, 이와 같이 방수코팅된 파쇄입자들을 시트 형태로 압착한 것을 코르크층(113)으로 사용하는 것이다. 이와 같이 방수코팅된 코르크 입자에 의해 습기에 취약한 코르크층(113)의 내구성을 향상시킬 수 있다.Furthermore, in order to prevent penetration of the adhesive as well as moisture penetration after installation, waterproof coating may be performed on each cork particle forming the cork layer 113. That is, in the process of manufacturing a cork sheet, the crushed particles obtained by crushing cork wood are subjected to a waterproof coating, and the waterproof-coated crushed particles are pressed into a sheet form and used as the cork layer 113. In this way, the durability of the cork layer 113, which is vulnerable to moisture, can be improved by the waterproof-coated cork particles.

오버레이(111), 모양지(112) 및 코르크층(113)의 합지 시의 온도조건은 120~150℃, 상하로 누르는 압력조건은 50~100kg/㎠의 환경 하에서 30~80분 동안 유지함으로써 합지, 즉 고압수지함침시트(110)를 달성할 수 있다.When combining the overlay (111), pattern paper (112), and cork layer (113), the temperature condition is 120~150℃, and the pressure condition for pressing up and down is maintained at 50~100kg/㎠ for 30~80 minutes. , That is, the high-pressure resin impregnated sheet 110 can be achieved.

이와 같이 코르크층(113)이 일체화된 고압수지함침시트(110)는 도 3에 도시된 바와 같이, 수성접착제로 이루어진 접착제층(120)이 도포된 본체(130)에 부착된다. 본체(130)는 합판 내지 목재로 이루어지며, 상하로 적층 부착된 구성들은 상,하 금형 사이에 개재시킨 상태에서 상기 상,하 금형을 통해 가압함으로써 상기 코르크층(113)이 본체(130)에 완전히 부착되도록 한다.As shown in FIG. 3, the high-pressure resin impregnated sheet 110 with the cork layer 113 integrated in this way is attached to the main body 130 on which the adhesive layer 120 made of water-based adhesive is applied. The main body 130 is made of plywood or wood, and the components laminated and attached top and bottom are sandwiched between the upper and lower molds and pressed through the upper and lower molds, so that the cork layer 113 is attached to the main body 130. Make sure it is completely attached.

이와 같이 얻어지는 쿠션 바닥재(100)는 도 4에 도시된 바와 같다. 고압수지함침시트(110) 표면의 항균 기능을 부여하기 위해 멜라민 95중량%, 은나노 입자 5중량%를 함유하는 항균 코팅제를 도포하여 경화처리한 것을 적용할 수 있다.The cushion flooring material 100 obtained in this way is as shown in FIG. 4. In order to provide an antibacterial function to the surface of the high-pressure resin impregnated sheet 110, an antibacterial coating containing 95% by weight of melamine and 5% by weight of silver nanoparticles can be applied and cured.

본 발명의 제2 실시예에 따른 쿠션 바닥재(200)는 도 5 및 도 6에 도시된 바와 같은 순서로 제조된다. 먼저 오버레이(211), 모양지(212) 및 코르크층(213)의 합지에 의해 달성되는 고압수지함침시트(210) 및 부착방법은 상기 제1 실시예에서 설명된 바와 동일하게 이루어지며, 이와 같이 코르크층(213)이 일체화된 고압수지함침시트(210)는 접착제층(220)이 도포된 본체(230) 상에 배치되고, 본체(230)의 저면에는 핫멜트 시트(240)와 제2 코르크층(250)이 배치된다. 제2 코르크층(250)의 밀도와 두께는 코르크층(213)과 동일하다.The cushion flooring 200 according to the second embodiment of the present invention is manufactured in the order shown in FIGS. 5 and 6. First, the high-pressure resin impregnated sheet 210 and the attachment method achieved by combining the overlay 211, the pattern paper 212, and the cork layer 213 are the same as those described in the first embodiment, and as follows. The high-pressure resin impregnated sheet 210 with the integrated cork layer 213 is disposed on the main body 230 to which the adhesive layer 220 is applied, and the hot melt sheet 240 and the second cork layer are on the bottom of the main body 230. 250 is placed. The density and thickness of the second cork layer 250 are the same as those of the cork layer 213.

상기와 같이 배치된 적층 구성을 상,하 금형 사이에 개재시킨 상태에서 상기 상,하 금형을 통해 가열 및 가압함으로써 코르크층(213)이 본체(230)의 상면에 부착되도록 함과 동시에 핫멜트 시트(240)를 가열에 의해 녹임으로써 이를 통해 본체(230)의 저면에 제2 코르크층(250)이 부착되게 한다.With the laminated structure arranged as above sandwiched between the upper and lower molds, the cork layer 213 is attached to the upper surface of the main body 230 by heating and pressing through the upper and lower molds, and at the same time, a hot melt sheet ( By melting 240 by heating, the second cork layer 250 is attached to the bottom of the main body 230.

이와 비교하여, 도 1의 종래기술에서 코르크 패널(60)은 150kg/㎥의 저밀도로 내부에 많은 공기구멍을 가지고 있고 그 두께 또한 2mm 이상이어서 열전달 효율을 크게 떨어뜨리는 관계로 본체(30)에 부착하는데 상기와 같은 핫멜트 시트(240)를 적용할 수 없었다. 더욱이, 접착제를 도포하여 본체(30)에 부착시키고자 할 경우에도 상기 접착제가 코르크 패널(60)의 내부로 쉽게 침투함에 따라 더 많은 양의 접착제를 사용할 수 밖에 없었고, 이로 인해 코르크 패널(60)의 물성이 변화하는 문제가 발생하게 되었다.In comparison, in the prior art of FIG. 1, the cork panel 60 has a low density of 150 kg/㎥, has many air holes inside, and is more than 2 mm thick, which greatly reduces heat transfer efficiency, so it is attached to the main body 30. However, the hot melt sheet 240 as described above could not be applied. Moreover, even when applying adhesive to attach it to the main body 30, a larger amount of adhesive had to be used as the adhesive easily penetrated into the interior of the cork panel 60, which resulted in the cork panel 60 A problem arose where the physical properties of the material changed.

본 발명에 따라 핫멜트 시트(240)을 이용한 본체(230)와 제2 코르크층(250)의 부착은 상기 제2 코르크층(250) 내부로 어떠한 접착성분이 침투되지 않게 해줌으로써 코르크층의 고유한 쿠션 및 방음 기능을 발휘할 수 있게 해준다.According to the present invention, the attachment of the main body 230 and the second cork layer 250 using the hot melt sheet 240 prevents any adhesive component from penetrating into the second cork layer 250, thereby maintaining the inherent properties of the cork layer. It provides cushioning and soundproofing functions.

핫멜트 시트(240)에는 원적외선 내지 음이온이 발생하는 성분, 예를 들어 황토, 옥, 자석, 게르마늄, 숯 등의 기능성 물질을 함유시킬 수도 있다.The hot melt sheet 240 may contain functional materials such as components that generate far infrared rays or negative ions, such as red clay, jade, magnet, germanium, and charcoal.

본 발명의 제3 실시예에 따른 쿠션 바닥재(300)는 도 7 내지 도 9에 도시된 바와 같이 제조된다. 먼저, 고압수지함침시트(310)는 접착제(320)가 도포된 본체(330)에 부착된다. 이때의 고압수지함침시트(310)는 종래 오버레이, 모양지 및 크라프트지가 상하로 적층되어 합지된 것이다.The cushion flooring 300 according to the third embodiment of the present invention is manufactured as shown in FIGS. 7 to 9. First, the high-pressure resin impregnated sheet 310 is attached to the main body 330 to which the adhesive 320 is applied. At this time, the high-pressure resin impregnated sheet 310 is a conventional overlay, patterned paper, and kraft paper stacked vertically and laminated.

그리고, 고압수지함침시트(310)가 부착된 본체(330)의 저면에는 핫멜트 시트(340)와 코르크층(350)이 배치된 상태에서 상,하 금형 사이에 개재시켜 가열 및 가압함으로써 상기 핫멜트 시트(340)가 열전달에 의해 가열되어 녹음에 따라 이를 매개로 코르크층(350)이 본체(330)의 저면에 부착된다.In addition, the hot melt sheet 340 and the cork layer 350 are disposed on the bottom of the main body 330 to which the high pressure resin impregnated sheet 310 is attached, and are sandwiched between the upper and lower molds to heat and pressurize the hot melt sheet. (340) is heated by heat transfer and melts, thereby attaching the cork layer (350) to the bottom of the main body (330).
