그리고, 본 발명의 우븐패브릭으로 이루어진 심재(150)는, 물결무늬를 갖도록 적어도 일측이 중첩되고, 상기 우븐패브릭에 대응토록 기재의 일측에 복수의 지지턱(117)이 금형의 가압성형에 의해 일체로 형성된다.And, the core material 150 made of the woven fabric of the present invention, at least one side overlaps so as to have a wave pattern, and a plurality of support jaws 117 on one side of the base material to correspond to the woven fabric are integrally formed by press molding of the mold. is formed with

이때, 상기 물결무늬는, 도 3에 도시된 바와 같이, 좌,우가 서로 높이 차를 두고 서로 엇갈리게 배치되는 지지봉(210)을 서로 교차하여 이동시키는 엑튜에이터(200)에 의해 일체로 형성된다.At this time, as shown in FIG. 3 , the wave pattern is integrally formed by an actuator 200 that crosses and moves the support rods 210 , which are disposed to be alternately arranged with a height difference between the left and right sides, as shown in FIG. 3 .

상기와 같은 구성으로 이루어진 본 발명의 동작을 설명한다.The operation of the present invention configured as described above will be described.

도2 내지 도6에서 도시한 바와같이 플로어링보드(100)는, 심재(150)가 적층되는 기재(110)와 상기 기재의 표면에 위치하여 상부면에 노출되는 표면재(190)의 적층구조로 이루어져 노출되는 표면재의 특성에 의해 원하는 강도 및 내스크래치성등을 구현하면서 심재에 의해 조습성을 향상을 가져오도록 한다.2 to 6, the flooring board 100 has a laminated structure of a substrate 110 on which a core material 150 is laminated and a surface material 190 positioned on the surface of the substrate and exposed to the upper surface. By the characteristics of the exposed surface material, the desired strength and scratch resistance are realized, while the moisture control is improved by the core material.

이때, 상기 심재(150)는 기재에 한층 이상으로 적층될 때 PET계열이면서 위사와 경사의 제직물인 우븐패브릭으로 이루어져 조습성을 향상시키게 된다.At this time, when the core material 150 is laminated on the substrate in one or more layers, it is made of PET-based woven fabric of weft and warp yarns to improve moisture control.

즉, 상기 심재는 도6의 주사전자현미경(SEM) 촬영 사진에서와 같이 섬유질이 얽혀져 있어 복수의 공기층을 형성함으로써 물의 흡수 및 건조가 용이하여 조습성을 높이게 된다.That is, as shown in the scanning electron microscope (SEM) photograph of FIG. 6 , the core material is entangled with fibers to form a plurality of air layers, thereby facilitating absorption and drying of water, thereby enhancing moisture control.

또한, 상기 표면재(190)는, 멜라민 수지에 함침된 모양지를 페놀수지에 함침된 펄프와 적층한 후 고온고압으로 압착한 HPL로서 이루어지면서 멜라민수지층과 모양지층 및 펄프층이 반복적인 실험에 의해 10:30:60의 비율을 갖도록 형성함으로써 최적의 내스크래치성, 내마모성, 압축강도의 상승을 가져오게 되었다.In addition, the surface material 190 is made as HPL by laminating a patterned paper impregnated with a melamine resin with pulp impregnated with a phenolic resin and then compressed at high temperature and high pressure, while a melamine resin layer, a patterned paper layer and a pulp layer are repeatedly tested. By forming it to have a ratio of 10:30:60, the optimum scratch resistance, abrasion resistance, and compressive strength were increased.

더하여, 본 발명의 우븐패브릭과 기재, 기재와 기재는, 25%의 EVA, 20%의 결합제, 35%의 흡수제, 20%의 물로 이루어진 접착제층(130)로서 열 접합되며, 결합제는 폴리비닐알콜이 흡수제로는 칼슘카보네이트가 사용되었다.In addition, the woven fabric of the present invention and the substrate, the substrate and the substrate are thermally bonded as an adhesive layer 130 composed of 25% EVA, 20% binder, 35% absorbent, and 20% water, and the binder is polyvinyl alcohol. Calcium carbonate was used as this absorbent.

이때, 상기 접착제층을 이루어진 각 성분의 함량 역시 출원인의 반복적인 실험으로 최적화 한 것이다.At this time, the content of each component constituting the adhesive layer was also optimized through repeated experiments of the applicant.

계속하여, 상기 기재(110)는, 우븐패브릭의 위사 및 경사로 이루어진 메쉬에 대응되는 다수의 요철(115)이 일체로 구비되어 기재와 심재의 접합시 접합면적을 넓혀 견고한 결합이 가능하게 된다.Subsequently, the substrate 110 is provided integrally with a plurality of irregularities 115 corresponding to the mesh made of the weft and warp yarns of the woven fabric, thereby expanding the bonding area when bonding the substrate and the core material, thereby enabling a strong bonding.

그리고, 본 발명의 우븐패브릭으로 이루어진 심재(150)는, 물결무늬를 갖도록 적어도 일측이 중첩되어 형성됨으로써 한번의 공정으로 단위면적당 밀도를 높혀 수분의 흡수효과를 극대화 시키게 된다.In addition, the core material 150 made of the woven fabric of the present invention is formed so that at least one side is overlapped to have a wave pattern, so that the density per unit area is increased in one process to maximize the water absorption effect.

이때, 상기 물결무늬는, 도 3에 도시한 바와 같이 좌,우에 위치하는 엑튜에이터(200)에 각각 일정간격으로 지지봉(210)이 연결될 때, 상기 좌,우의 지지봉은 서로 높이 차를 가지면서 엇갈리게 배치되어, 좌,우엑튜에이터 및 이에 연결되는 지지봉이 서로 교차하여 이동하는 상호작용을 통하여 지지봉에 엇갈리게 걸쳐진 심재가 일정 너비 단위로 오버랩되어 접힘으로써 단위면적당 밀도를 높이도록 한다.At this time, the wave pattern is, as shown in FIG. 3, when the support rods 210 are connected to the actuators 200 located on the left and right at regular intervals, respectively, the left and right support rods are staggered while having a height difference from each other. Arranged, the left and right actuators and the support rods connected thereto cross each other and move, so that the core material crossed over the support rods overlaps and folds in a unit of a certain width to increase the density per unit area.

또한, 상기 요철(115) 및 지지턱(117)은 롤상의 금형의 가압회전에 의해 연속하여 형성된다.In addition, the irregularities 115 and the support jaws 117 are continuously formed by the rotation of the mold on the roll.

그리고, 소방청고시등에 의하면 합판, 섬유판, 목재 및 기타물품 (이하 “합판등”이라 한다.)의 방염성능기준은 잔염시간 10초 이내, 잔신시간 30초 이내, 탄화면적 50㎠ 이내,탄화길이 20㎝ 이내이어야 한다라고 규정되어 있으며, 본 발명은 도4와 같이 상기와 같은 방염성능 시험을 수행한 결과 모든 조건이 규정내인 것으로 나타났다.And, according to the notification of the Fire Department, the flame-retardant performance standards for plywood, fiberboard, wood and other articles (hereinafter referred to as “plywood, etc.”) are within 10 seconds of afterflame time, within 30 seconds of after-burn time, within 50cm of carbonization area, and 20 carbonization length. It is stipulated that it should be within cm, and the present invention shows that all conditions are within the regulations as a result of performing the flame-retardant performance test as described above as shown in FIG. 4 .

또한, 도5와 같이 경사 인장형 미끄럼 시험기를 이용하여 고분자 바닥재(목재 플라스틱 복합재 바닥판) 시험방법(KS M 3510:2010)에 의해 조건별 미끄럼저항계수(C.S.R)를 측정한 결과 역시 미끄럼저항성 기준인 C.S.R 0.40 이상을 만족하고 있는 것입니다.In addition, the result of measuring the coefficient of slip resistance (C.S.R) for each condition by the test method (KS M 3510:2010) for polymer flooring (wood-plastic composite flooring) using an inclined tension type slip tester as shown in FIG. 5 is also the slip resistance standard. It satisfies C.S.R 0.40 or higher.

계속하여, 본 발명은 아래의 [표1] 및 [표2]와 같이 시험편 기본 구성 중 PLAIN은 최하부 합판으로 이루어진 기재와 표면재(HPL)로만 이루어지고, WF는 PLAIN 시험편 구성의 중앙부에 심재가 더 포함되는 구성으로 상기 WF는 PET계열 우븐패브릭이 적층된다.In the present invention, as shown in [Table 1] and [Table 2] below, PLAIN consists only of the base material and the surface material (HPL) made of the lowest plywood among the basic components of the specimen, and the WF has a core material in the center of the PLAIN specimen configuration. In the included configuration, the WF is laminated with a PET-based woven fabric.

상기와 같은 시험편은, 수분 흡수량을 시험하기 위해 상온의 물에 침지 후 수분을 흡수시켜 시간 변화에 따른 최종 흡수량을 비교하였고, 열전달성을 알기 위해 60℃의 열판플레이트 상부에 시험편을 올려 시간의 변화에 따라 표면 온도변화를 열화상 카메라로 촬영하였다. The test piece as described above was immersed in water at room temperature to test the amount of moisture absorption and then absorbed moisture to compare the final absorption amount according to time change. Accordingly, the surface temperature change was photographed with a thermal imaging camera.

이상과 같은 시험에 의하면 본 발명은, 상온의 수분에 시간별로 침지 된 시험편의 흡수량을 무게 대비 비교한 결과 WF(Woven Fabric)가 PLAIN 대비 약 40% 더 흡수하였으며, PLAIN은 10분 이후 흡수가 멈춘 것으로 나타났지만, WF는 흡수가 지속 이루어진 것으로 나타나 조습성을 향상을 가져옴을 알 수 있다.According to the above test, in the present invention, as a result of comparing the weight of the absorption amount of the specimen immersed in moisture at room temperature for each hour, WF (Woven Fabric) absorbed about 40% more than PLAIN, and PLAIN stopped absorbing after 10 minutes. However, it can be seen that WF is shown to be continuously absorbed, resulting in improved humidity control.

또한, 단열성시험은, WF만 적용된 시험편이 PLAIN 대비 약 2℃ 정도 온도차이가 있었고 단열 액상을 분무한 경우 최대 5℃의 열전달성 차이가 나타나 우븐패브릭의 낮은 열전달성과 단열 액상도 추가적으로 열전달성을 감소시켜 주는 것을 알 수 있다.In the thermal insulation test, the WF-only specimen had a temperature difference of about 2°C compared to PLAIN, and when the insulating liquid was sprayed, a maximum of 5°C difference in heat transfer was observed. You can see that it does
