Description

거푸집 제작용 화이바보드의 제조방법{THE METHOD OF MAKING FIBER BOARD FOR FORM WORK}Manufacturing method of fiber board for formwork {THE METHOD OF MAKING FIBER BOARD FOR FORM WORK}

본 발명은 폐기되는 각종 합성수지 화이바섬유를 이용한 거푸집 제작용 화이바보드(Fiber Board)의 제조방법에 관한 것으로 구체적으로는 화이바섬유 제조과정에서 불량(Loss)으로 발생되는 아크릴화이바, 폴리에스텔화이바, 폴리아마이드화이바, 폴리푸로피렌화이바 그리고 이들로 직조된 직물의 넝마 스크랩 등을 원료로 한 거푸집(Form Work) 제작용 화이바보드(Fiber Board)의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a fiber board for formwork using various synthetic resin fiber fibers discarded. Specifically, acrylic fiber, polyester fiber, polyamide, which are generated as defects in the fiber manufacturing process, The present invention relates to a manufacturing method of a fiber board for forming a formwork made from a fiber bar, polypuroprene fiber, and rag scraps of a fabric woven therefrom.

종래에 상기와 같은 목적으로 제조되는 화이바보드는 목분 또는 미세한 톱밥 등을 충진재로 하여 폴리푸로피렌을 골고루 섞은 혼합물을 가열수단과 혼련 압출하여 시트화하므로서 화이바보드를 얻을 수 있었다. 이와 같은 보드는 보강재가 섬유상이 아니고 분말 또는 입자상이여서 충격강도, 굴곡강도 등이 극히 약하고 특히 폴리푸로피렌은 내한성이 약하여 추운 겨울에는 보드면에 균열이 발생하거나 쉽게 깨어지므로 콘크리트몰탈에 의한 강력한 내압을 받게 되는 거푸집(Form Work) 용도로는 적합지 않을 뿐만 아니라 큰 위험이 뒤따른다.In the conventional fiber board manufactured for the above purpose, the fiber board can be obtained by kneading and extruding a mixture of polypuropyrene evenly mixed with a heating means using wood flour or fine sawdust as a filler. These boards are not fibrous but powdery or granular, so their impact strength and flexural strength are extremely weak. In particular, polypropylene has very low cold resistance, so cracks or breaks easily on the board surface during cold winters. Not only is it not suitable for the form work it receives, but it also carries a great risk.

종래 또 다른 화이바보드로는 목분, 폐지 등을 고루 섞고 용제에 용해시킨 페놀수지나 요소수지 등의 열경화수지용액으로 분사합침하여 시트상으로 성형가열 경화시키므로서 얻어지는 화이바보드는 우선 용제를 사용하므로서 작업환경이 극히 나쁘고 열경화시에 소요되는 열에너지의 손실과 경화하는데 장시간이 소요되므로 생산능률이 크게 떨어진다.Another fiber board conventionally obtained is a fiber board obtained by spraying and impregnating with a thermosetting resin solution such as phenol resin or urea resin, which is evenly mixed with wood powder and waste paper, and dissolved in a solvent. Extremely bad working environment, loss of heat energy for heat curing and long time to harden, greatly reduce production efficiency.

그밖에도 국내 특허공보 특 1987-0005764호 기재된 내용은 발명의 명칭을 화이바보드 제조방법으로 한 발명으로서 폴리프로피렌 폐포대를 분쇄한 분쇄물과 폴리에스터, 폴리아마이드, 아크릴 등의 폐화학섬유를 절단한 절단화이바를 균일하게 섞고 소면기로 개섬하여 웨브(Web)상태의 일정형으로 1차 성형하고 이를 가열실(Heating Chamber)에 넣고 약 200℃로 40초간 가열한 후 냉각압한으로 성형하여 화이바보드를 얻는 방법이다.In addition, the contents described in Korean Patent Publication No. 1987-0005764 are an invention in which the name of the invention is a fiber board manufacturing method, which cuts pulverized materials obtained from pulverizing polypropylene pyrophore and waste chemical fibers such as polyester, polyamide, and acrylic. Mix the cutting fiber uniformly and open it with a carding machine to form the web firstly into a certain type of web state, put it in a heating chamber, heat it to about 200 ℃ for 40 seconds, and then mold it with cooling pressure. How to get.

위의 방법에서 판단되는 것처럼 분말화된 폴리푸로피렌을 상기 폴리에스텔, 폴리아마이드, 아크릴섬유와 혼합하여 소면기로 개섬하는 과정에서 폴리푸로피렌 분쇄물이 아래쪽으로 집적되어 웨브상태로 가열실에서 가열할시 접착제(결합제)로 작용하는 PP가 균일하게 분산되지 못하므로 제품의 균질성이 떨어지고 성형 후 가열실(200℃에서 40초간)의 온도와 시간으로는 PP가 완전 용융되어 확산될 수도 없으므로 제조된 화이바보드에 PP용융 응고물이 편중되거나 적어도 220℃이상의 용융점을 갖는 폴리아마이드 및 폴리에스텔화이바가 표면으로 표출되어 평활한 표면이 요구되는 거푸집판제로서는 적합지 않다.As determined by the above method, the powdered polypuropyrene is mixed with the polyester, polyamide, and acrylic fiber to be opened with a carding machine. When the PP acting as an adhesive (binding agent) is not uniformly dispersed, the homogeneity of the product is inferior, and the temperature of the heating chamber (for 40 seconds at 200 ° C) after molding causes the PP not to be completely melted and diffused. It is not suitable for formwork which requires a smooth surface because polyamide and polyester fiber having a melting point of at least 220 ° C. or more are concentrated on the board or the PP melt coagulates.

또 국내특허공개번호(특1990-0009273)의 화섬판제 제조방법에서와 같이 아크릴섬유설, 나이론섬유설, 폴리에스텔섬유설, 면섬유를 50∼100㎜길이로 절단 균일하게 혼합시키고 이를 타면기로 개섬한 다음 이를 웨브(Web)상태로 (성긴조직상태) 매드를 얻은 다음 온도 200∼250℃ 압력 650∼700톤의 하드프레스에서 3∼10분간 프레싱하고 냉각프레스에서 300톤의 압력으로 2∼7분간 냉각함으로서 화섬판재를 제조하는 방법에 관한 것으로 이는 한 장의 화장판재를 얻기 위하여 5∼17분이 소요되고 엄청난 압력이 소요됨으로 극히 비생산적이면서 엄청난 에너지가 소요되는 방법이며 이와 같은 고압상태의 높은 온도범위에서는 폴리푸로피렌과 융점이 비슷한 아크릴섬유(화이바)는 물론 이보다 비교적 높은 융점을 갖는 폴리아마이드(하중이 없는 상태에서 220℃) 및 폴리에스텔(하중이 없는 상태에서 250℃)화이바 까지도 완전히 용융하여 화이바 보강에 의한 강력한 힘을 갖는 화섬판재 또는 화이바보드는 기대할 수 없다.In addition, acrylic fiber, nylon fiber, polyester fiber, and cotton fiber are cut into 50 to 100 mm lengths and uniformly mixed, and then opened with other cotton wool as in the method of manufacturing the sum thread plate of Korean Patent Publication No. (Specific 1990-0009273). Next, a web (coarse tissue) was obtained in a web state, and then pressed for 3 to 10 minutes in a hard press at a temperature of 200 to 250 ° C. and a pressure of 650 to 700 tons and cooled at a pressure of 300 tons for 2 to 7 minutes in a cooling press. It is a method of manufacturing a fiber board material, which takes 5 to 17 minutes to obtain a single sheet of cosmetic board and takes tremendous pressure, which is extremely unproductive and requires tremendous energy. Acrylic fibers (fibers) with melting points similar to pyrene, as well as polyamides (220 ° C without load) and poles with higher melting points Fibers or fiber boards that are completely melted even in polyester (250 ° C without load) and have strong strength by fiber reinforcement cannot be expected.

다시 말하면 커팅작업, 소면기에 의한 개섬공정, 웨브상태의 매드 제작공정 등 일련의 공정이 필요없고 각각의 합성수지화이바나 설을 그대로 용융 혼합 브렌딩하여 압출성형으로 얻어지는 합성수지의 판재에 불과한 것이라 하겠다.In other words, it does not require a series of processes such as cutting work, carding process by carding machine, and mad manufacturing process of web state, and it is just a synthetic resin plate obtained by extrusion mixing by melt blending each synthetic resin bar or sulfide as it is.

본 발명은 전술한 바와 같이 종래의 화이바보드 또는 화섬판재의 기능은 물론 그 제조방법에 관한 문제점을 개선한 화이바보드의 제조방법을 제공함에 목적이 있으며 구체적으로는 고융점을 갖는 폴리푸로피렌화이바, 아크릴화이바, 나일론화이바 및 폴리에스텔화이바의 화이바로서의 보강기능을 살릴 수 있고 생산능률을 크게 향상시킬 수 있으며 표면 평활성이 우수한 거푸집 제작용 화이바보드의 제조방법을 제공함에 있다.The present invention has an object to provide a method for manufacturing a fiber board that improves the problems of the conventional fiber board or the fiber board material as well as the manufacturing method as described above, specifically a polypropylene pyrofiber having a high melting point, The present invention provides a method for manufacturing a fiber board for forming a die, which can utilize the reinforcement function of acrylic fiber, nylon fiber and polyester fiber as a fiber, and can greatly improve production efficiency.

본 발명은 폐기되는 합성수지화이바(화섬사)를 재활용하는 것이므로 원료확보에 제한을 받지 않도록 가능한한 다종의 합성수지 화섬사를 사용하는 것이 유리하며 여기에서는 폐기되는 폴리푸로피렌화이바, 아크릴화이바, 폴리아마이드화이바, 폴리에스텔화이바 중에서 선택되는 하나 이상의 화이바를 선택 사용하게 되고 이들을 화이바보드 조직내에서 화이바 상태로 존재하도록 결합시키는 원료를 융점이 상기 합성수지 보다 낮고 용융점에서 점도가 낮아 침투가 용이한 폴리에치렌을 사용한다.Since the present invention recycles discarded synthetic resin fibers (fiber yarns), it is advantageous to use as many synthetic resin fiber yarns as possible so as not to be limited to securing raw materials. Herein, polypuroprene fibers, acrylic bars, polyamide fibers, and polyamide fibers, One or more fibers selected from esterified fibers are selected and used to combine them so that they are present in the fiber structure in the fiber board. Polyethylene is easily infiltrated because the melting point is lower than that of the synthetic resin and the viscosity is low at the melting point.

또한 위와 같은 원료로서 본 발명에 의한 거푸집 제작용 화이바보드의 제조방법은 폴리에치렌을 상기 소면기로 개섬된 화이바와 함께 혼합하여 성형하는 것이 아니고 상기 화섬화이바를 소면기로서 개섬한 화이바로 웨이브상태(성글은 부직포상태의 조직)로 성형한 매트를 폴리에치렌 융점보다 높고 선택된 화이바들 중에서 가장 낮은 융점을 갖는 합성수지(화이바)의 용융점 보다는 낮은 온도로 열처리한 매트에 미리 용융된 폴리에치렌 용액은 침투 및 표면처리하는 방법으로 이를 구체적으로 설명하면 도 1에서와 같이 선택된 합성수지 폐설을 절단 개섬하여 일정두께의 열처리된 웨브상태(성근부직포상태)의 매트(1, 1')를 양측에서 연속적으로 공급하여 일정간격을 갖는 가열 맞물림 로울러(2, 2')를 통과 적층시킴과 동시에 만나는 양매트 사이에 제1 T다이(3)로부터 압출되는 폴리에치렌 용융막(3')이 삽입 첨착시킴과 동시에 로울러의 가압으로 매트 조직에 균일하게 침투되고 두께가 압축된 상태로 제2의 T다이(5)로부터 압출되는 폴리에치렌 용융막(5')이 매트(1, 1')의 외부로 첨착 코딩됨과 동시에 매트 조직내로 침투되고 더욱 축소되어 냉각실(6)을 통과시킨 다음 다시 맞물림 로울러(7, 7')를 통과시켜 절단기(8)로 절단함을 특징으로 하는 거푸집 화이바보드의 제조방법이라 할 수 있다.In addition, the manufacturing method of the fiber board for formwork according to the present invention as a raw material as described above is not mixed with the poly ethylene and the fiber to be opened with the carding machine, but not molded, and the fiber is opened in a fiber state in which the fiber is opened as a carding machine. Sunggle's pre-melted polyethylene solution is infiltrated into a mat formed with a non-woven tissue) and heat-treated to a temperature higher than the melting point of the synthetic resin (fiber) having a higher melting point than the polyethylene styrene and the lowest melting point among the selected fibers. And specifically described in the method of surface treatment by cutting and opening the selected synthetic resin waste snow as shown in Figure 1 by continuously supplying the mat (1, 1 ') of the heat treated web state (adult non-woven fabric state) of a certain thickness from both sides Between the mats which meet at the same time as laminating through the heating engagement rollers 2 and 2 'with a predetermined interval. The second T-die 5 in the state where the poly-ethylene molten film 3 'extruded from the 1-T die 3 is inserted and attached, and is uniformly penetrated into the mat structure by pressurization of the roller and the thickness is compressed. The polyetchene molten film 5 ', which is extruded from, is impregnated and coded out of the mats 1, 1' and simultaneously penetrates into the mat tissue and further shrinks, passes through the cooling chamber 6, and then reengages the rollers 7, It can be referred to as a manufacturing method of the die fiber board, characterized in that the cutting through 7 ') through the cutter (8).

여기에서 각 수지의 용융점은 분자량의 차이에 따라서 약간의 차이가 있지만 폴리에스텔수지는 약 250℃, 폴리아마이드는 210∼220℃, 알크릴수지는 180℃부근이고 폴리푸로피렌 168∼171℃이며 폴리에치렌은 120℃ 전후로서 웨브상매트의 열처리 온도는 130∼160℃ 범위가 적당하고 열쳄버내를 통과시켜 열처리하며 합성수지화이바에 대한 폴리에치렌의 첨가비율은 합성수지화이바의 종류에 따라 약간의 차이는 있으나 30∼35wt% 정도면 매트의 조직의 내부간극을 충분히 메울수 있고 또한 표면의 평활성 형성에 문제가 생기지 않는다. 또한 웨브상매트를 열처리하는 이유는 용융폴리에치렌의 응고화가 빨리 일어나지 않고 열에 의한 점도를 낮게 하므로서 극히 미세한 수미크론의 화이바 사이에도 쉽게 침투되어 화이바보드의 전체적인 물성을 향상시킴에 도움을 줄 수 있다.Here, the melting point of each resin is slightly different depending on the molecular weight difference, but the polyester resin is about 250 ° C, the polyamide is 210 to 220 ° C, the acrylate resin is around 180 ° C, and the polypuropyrene is 168 to 171 ° C. Ethylene is around 120 ℃ and the heat treatment temperature of the web phase mat is in the range of 130 ~ 160 ℃, and the heat treatment is carried out through the heat chamber, and the ratio of the addition of polyethylene to the synthetic fiber is slightly different depending on the type of synthetic fiber. However, about 30 to 35wt% can sufficiently fill the internal gap of the tissue of the mat, and there is no problem in forming the smoothness of the surface. In addition, the reason why the heat treatment of the web phase mat is that the coagulation of the molten polystyrene does not occur quickly and the viscosity due to the heat is low, so that it can easily penetrate between the extremely fine micromicron fibers, which may help to improve the overall physical properties of the fiber board. .

본 발명에 의한 거푸집 제작용 화이바보드는 화이바보드 조직내에 보강섬유가 그대로 존재하므로서 충격강도, 굴곡강도가 극히 우수하며 더욱이 표면 평활성이 뛰어나 시멘트 경화 후 거푸집 제거가 용이하고 경화된 표면이 평활하여 미장 또는 마감처리 등이 필요 없다.The fiber board for forming formwork according to the present invention has an excellent impact strength and flexural strength because the reinforcing fibers are present in the fiber board structure as it is, and furthermore, the surface smoothness is easy to remove the formwork after cement hardening, and the hardened surface is smoothed to make plastering or There is no need for finishing.

또 제조과정에 있어서도 성형에 소요되는 시간을 단축할 수 있고 생산성을 크게 향상시킬 수 있으며 내한성이 우수하여 한냉지나 겨울에도 사용할 수 있는 이점이 있는 거푸집 제작용 화이바보드의 제조방법이라 할 수 있다. In addition, in the manufacturing process, it can shorten the time required for molding, can greatly improve the productivity and excellent cold resistance, it can be said to be a manufacturing method of the fiber board for forming the formwork having the advantage that can be used even in cold or winter.
