Abstract
Description
본 발명은 건축용 플라스틱 판재에 관한 것으로서, 보다 상세하게는 합성섬유 원사를 서로 연결하여 직조한 부직포를 플라스틱 합판 속에 내장 성형시켜 인장강도와 충격흡수율을 높이는 것은 물론, 수분에 의한 신축변형이 없고 내구성이 강한 건축용 플라스틱 판재 및 이의 제조방법에 관한 것이다.The present invention relates to a plastic sheet for building, and more particularly, to form a woven nonwoven fabric by connecting synthetic fiber yarns to each other in a plastic plywood to increase the tensile strength and impact absorption, as well as the elastic deformation and moisture resistance It relates to a strong building plastic sheet and a method of manufacturing the same.
일반적으로 토목·건축용 합판이나 판재는 목재, 플라스틱 합판, 폐수지를 이용한 판재 또는 금속 판재 등 다양한 종류의 합판이나 판재가 사용되고 있다. 이중 목재만으로 된 판재는 가격이 싸고 가공이 쉽다는 장점이 있으나, 수분에 의한 팽창, 변형 및 부패의 단점이 있고, 플라스틱만으로 된 판재는 못질을 할 수 없고, 표면가공 등의 작업성이 좋지 않음은 물론 기온에 따라 변형이 생길 수 있으며 가격이 비싸다는 단점을 안고 있다. 또한 금속으로 된 경우에는 무겁고 원가가 비싸며 작업성이 용이하지않다는 단점이 있다.In general, various types of plywood or plate, such as wood, plastic plywood, plate or metal plate using waste resin is used as civil engineering and building plywood. The plate made of only wood has the advantage of being cheap and easy to process, but has the disadvantages of expansion, deformation and decay due to moisture, and the plate made of plastic cannot be nailed and workability such as surface processing is poor. Of course, there is a disadvantage that the deformation may occur depending on the temperature and the price is expensive. In addition, the metal has a disadvantage of being heavy, expensive and not easy to work.
상기와 같은 판재들의 단점을 해결하기 위해 재질이 다른 것들을 조합하여 만들기도 하나, 목재가 들어가는 경우에는 목재의 특성인 수분에 의한 변형, 강도저하, 목재와 플라스틱 간의 분리현상 등 여전히 문제점이 남게 된다.In order to solve the shortcomings of the boards as described above, but also made of a combination of different materials, when the wood enters, there is still a problem such as deformation due to moisture, deterioration of strength, separation between wood and plastic.
또한 플라스틱에 유리섬유를 함침하여 사용하는 경우도 있으나, 이는 판재가 가벼우면서도 강성을 유지하는데는 효과적일지라도 가격이 비싸고 유리섬유가 유해물질이어서 제조 작업시 몸이 따갑고 가려움증을 유발하기도 하는 단점이 있다.In addition, there is a case in which the plastic is impregnated with glass fiber, but this is an expensive plate and effective to maintain the rigidity, but the price is expensive and the glass fiber is a harmful substance that causes the body swelling and itching during manufacturing work.
또한 재활용플라스틱만으로 판재를 만드는 경우에는 강도가 약하다는 단점을 갖고 있다.In addition, there is a disadvantage that the strength is weak when the plate made of recycled plastic only.
이들과 관련된 종래기술로 실용신안 공개 제2001-201호에서는 겹층으로 이루어진 합판의 재단된 4측면에 수분 침투방지 및 취급 시 충격방지용 우레탄계 합성수지층을 형성시킨 콘크리트 거푸집용 합판을 공개하고 있으나 상기와 같이 목재와 수지와의 이종 재질에 따른 문제점은 여전히 해결하고 있지 못한다.In the related art, Korean Utility Model Publication No. 2001-201 discloses a plywood for concrete formwork in which a urethane-based synthetic resin layer is formed on the cut four sides of a laminated plywood to prevent moisture penetration and to prevent impact during handling. The problem of different materials between wood and resin is still not solved.
또 다른 종래기술인 등록특허 제10-509900호에서는 판재의 내충격성 및 기계적 강도를 증가시키고 사용횟수를 늘리고자 강화섬유 및 폴리우레탄계 접착제를 사용하는 복합판재 및 그 제조방법을 개시하고 있으나, 열경화성 수지 접착제를 사용하여야 하고 열가소성수지, 충전제, 가공 조제 등으로 혼합 수지판을 만들어야하는 등 복잡한 구조로서 실시하기가 곤란하며 비경제적인 문제점을 안고 있다.Another prior art Patent Registration No. 10-509900 discloses a composite plate using a reinforced fiber and a polyurethane-based adhesive and its manufacturing method to increase the impact resistance and mechanical strength of the plate and increase the number of uses, but the thermosetting resin adhesive It is difficult to carry out as a complicated structure, such as to make a mixed resin plate with a thermoplastic resin, a filler, a processing aid, etc., and has an uneconomical problem.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위한 것으로서,The present invention is to solve the problems of the prior art as described above,
가볍고, 수분에 의한 변형이 없으며 강성을 유지하면서도 쉽게 파손되지 않고 내충격성을 갖고 있으며 내구성이 우수하고, 사용 후 재활용이 쉬우며 유지보수가 용이한, 건축용 플라스틱 판재와 그 제조방법을 제공함에 그 목적이 있다.To provide a plastic sheet for construction and its manufacturing method which is light, free from deformation by moisture, easy to maintain while maintaining rigidity, impact resistance, excellent durability, easy recycling after use, and easy maintenance. There is this.
본 발명은 상기와 같은 본 발명의 목적을 달성하기 위하여;The present invention to achieve the above object of the present invention;
플라스틱 판재와 부직포 그리고 상기 부직포 상부의 플라스틱 판재로 이루어지는 건축용 플라스틱 판재를 제공한다.Provided is a building plastic sheet consisting of a plastic sheet and a nonwoven fabric and a plastic sheet above the nonwoven fabric.
상기에서 플라스틱 판재는 폴리프로필렌(PP), 폴리에틸렌(PE), 에이비에스(ABS), 폴리카보네이트(PC) 등 어느 것이나 또는 합성으로 사용할 수 있고 재활용플라스틱을 사용하여도 된다.In the above-described plastic sheet, any of polypropylene (PP), polyethylene (PE), ABS (ABS), polycarbonate (PC), or the like may be used synthetically, or recycled plastic may be used.
또한 상기에서의 부직포는 PE, PP, ABS, PC, 카본 등 합성수지 원사를 사용하여 직조된 것이면 모두 사용할 수 있고, 바람직하게는 상기 부직포를 펀칭하여 미세 홀을 형성시켜 사용함이 좋다.In addition, the nonwoven fabric may be used as long as it is woven using synthetic resin yarns such as PE, PP, ABS, PC, carbon, and preferably, the nonwoven fabric is punched out to form fine holes.
본 발명은 또한 상기와 같이 하부플라스틱 판재 위에 미세 홀이 형성된 부직포를 올려놓고 그 위에 다시 플라스틱 판재를 놓은 후 가열 압착하는데 이때의 온도는 플라스틱 판재의 용융온도보다 조금 낮은 온도로 가열함이 바람직하다.The present invention also put a non-woven fabric with a fine hole formed on the lower plastic plate as described above, and then put the plastic plate again on it and heat-compression, the temperature at this time is preferably heated to a temperature slightly lower than the melting temperature of the plastic plate.
물론 상기에서 플라스틱 판재와 부직포를 여러 겹으로 하여도 된다.Of course, you may make multiple layers of a plastic board material and a nonwoven fabric in the above.
본 발명에 의하면 플라스틱 판재와, 플라스틱 판재 재료와 같은 것으로 만들어지는 부직포를 이용함으로서 재활용이 용이하고 부직포 내의 미세 홀로 플라스틱이 용융되어 흘러들어가서 상하플라스틱 판재가 강하게 밀착되어 강성을 유지하면서도 가볍고 내충격성과 내구성이 우수하며 수분에 의한 변형이 없고 유지보수가 용이할 뿐만 아니라 환경오염을 방지할 수 있음은 물론 경제적으로도 우수한, 건축용 플라스틱 판재를 제공하는 효과를 가져 올 수 있게 된다.According to the present invention, by using a plastic plate and a nonwoven fabric made of the same material as the plastic plate material, it is easy to recycle and the plastic melts and flows into the fine holes in the nonwoven fabric so that the upper and lower plastic plates are tightly adhered to maintain the rigidity, while being lightweight, impact resistance and durability. Excellent and free from deformation by moisture, easy maintenance and environmental pollution prevention as well as economically excellent, it can bring the effect of providing a plastic sheet for building.
본 발명을 실시하기 위해서는 먼저, 폴리프로필렌(PP), 폴리에틸렌(PE), 에이비에스(ABS), 폴리카보네이트(PC) 등으로 만들어지거나 이들 재료를 혼합 또는 재활용플라스틱을 사용하여 판재를 만든다.In order to practice the present invention, first, a plate is made of polypropylene (PP), polyethylene (PE), ABS (ABS), polycarbonate (PC), or the like, or by mixing or recycling these materials.
또한, 폴리프로필렌(PP), 폴리에틸렌(PE), 에이비에스(ABS), 폴리카보네이트(PC), 카본(cabon) 등의 합성수지 원사 또는 재활용 원사를 사용해 직조한 후 통상의 부직포를 만들고, 본 발명의 실시를 위해 상기 원사에 펀칭하여 홀 구멍이 형성되도록 한다.In addition, after weaving using a synthetic resin yarn or recycled yarn such as polypropylene (PP), polyethylene (PE), ABS (ABS), polycarbonate (PC), carbon (cabon) and the like to make a normal nonwoven fabric of the present invention, The holes are punched into the yarn for implementation so that hole holes are formed.
상기와 같이 만들어진 플라스틱 판재를 일정크기로 절단 후 약 240℃까지의 온도로 예열시킨다. 그러면 플라스틱 판재가 반 용융상태가 되는데 이때 플라스틱 판재 위에 홀 구멍이 형성된 부직포를 안치시키고 그 상부에 반 용융상태의 플라스틱 판재를 또 안치시킨 후 약 1500t의 압력을 가하면서 압착시키는데 이때에도 플라스틱 판재가 용융되기 전의 온도까지 열을 주면서 압착시킨다.The plastic sheet made as described above is cut to a predetermined size and then preheated to a temperature of about 240 ° C. Then, the plastic sheet is semi-melted. At this time, the non-woven fabric with hole holes is placed on the plastic sheet, and the semi-molten plastic sheet is placed on the upper portion of the plastic sheet. Press to heat to the temperature before it is pressed.
물론 상기 압착성형은 일정온도로 반 용융상태의 플라스틱 판재가 되도록 플라스틱 판재를 가열로에 통과시킨 후 금형에 삽입하고 부직포를 안치시킨 후 다음의 반 용융플라스틱 판재를 안치 후 상기 압력으로 압착시킬 수도 있다. 물론 이때 플라스틱 판재와 부직포를 여러 겹으로 할 수 있고 박판형으로 하여 다층구조로 하여도 된다.Of course, the press molding may pass the plastic sheet through a heating furnace so as to become a semi-molten plastic sheet at a predetermined temperature, and then insert the sheet into a mold, settle the nonwoven fabric, and then press and hold the next semi-molten plastic sheet. . Of course, at this time, the plastic sheet and the nonwoven fabric may be made in multiple layers, and may have a multilayer structure.
상기와 같이 반 용융상태의 상하 플라스틱 판재 사이에 홀 구멍이 형성된 부직포가 안착된 것을 가열 압착하게 되면 부직포 내의 홀 구멍으로 거의 용융된 플라스틱이 서로 융합되면서 강한 밀착력과 강성을 갖게 되는 것이다.As described above, if the non-woven fabric having a hole hole is seated between the upper and lower plastic plates in a semi-melt state, heat-compression bonding of the molten plastic into the hole holes in the non-woven fabric results in strong adhesion and rigidity.
즉, 부직포는 원사의 일부가 녹으면서 플라스틱 판재와 결합하고 또 부직포 내의 홀 구멍을 통해 상하플라스틱이 강하게 결합됨은 물론 원사 자체의 모습이 남게 되어 서로의 결합력에 의해 강성이 좋게 되고 판재의 뒤틀림을 방지할 수 있게 된다. 또한 내부의 원사에는 미세기공이 남아 있으므로 충격흡수나 방음효과도 얻을 수가 있게 된다.In other words, the nonwoven fabric is combined with the plastic sheet as the part of the yarn melts, and the upper and lower plastics are strongly bonded through hole holes in the nonwoven fabric, as well as the appearance of the yarn itself, so that the rigidity is good due to the mutual bonding force and prevents the warping of the plate. You can do it. In addition, since micropores remain in the yarn inside, shock absorption or sound insulation effects can be obtained.
또한 상하플라스틱 판재나 내부의 부직포가 거의 같은 재질이므로 용융하여 재사용할 수 있는 장점도 갖게 된다.In addition, since the upper and lower plastic plates and the inner nonwoven fabric are almost the same material, it also has the advantage of being melted and reused.
