본 발명은 산업폐기물인 페타이어, 폐고무, 천(섬유), 가죽, 제지스러지, 톱밥 등의 산업폐기물을 이용하여 건설공사에서 사용되는 거푸집판넬을 제조하는 방법과 그 거푸집판넬을 제공하기 위한 산업폐기물을 이용한 건설공사용 거푸집판넬을 제조하는 제조방법과 그 거푸집판넬에 관한 것이다.The present invention is to provide a method for manufacturing a formwork panel used in construction work using industrial waste, such as industrial waste such as tires, waste rubber, cloth (fiber), leather, paper waste, sawdust, and to provide the formwork panel The present invention relates to a manufacturing method for manufacturing formwork panels for industrial construction using industrial waste and formwork panels.
현재 건설공사, 토목공사 현장에서 콘크리트설시에 흔히 합판으로 구성된 거푸집판넬이 사용되고 있다. 이러한 거푸집판넬은 첨부한 도면 제1도에서와 같이 일정한 두께와 크기를 가진 합판(1)의 끝단에 강도를 보지하기 위한 각목(角木)(2)을 고정하는 방법에 의해 구성된 것을 이용하고 있다.Currently, formwork panels composed of plywood are used in concrete construction at construction and civil engineering sites. This formwork panel is used by the method of fixing the wood 2 for holding the strength at the end of the plywood (1) having a constant thickness and size as shown in FIG. .
이러한 종래의 거푸집판넬은 제조된 합판을 절단 및 각목의 절단과 재부착을 요하는 2차적인 공정에 의해 제조되었고, 또한, 종래의 거푸집판넬은 목재로만 제조되었기 때문에 원재료원가의 고가, 무게가 무겁고 통상노천에서 야적되기 때문에 우천시 수분을 흡수하게 되므로 이와 같은 상태에서는 강도가 떨어져 어느정도 건조상태를 유지한 상태에서 사용해야 한다.The conventional formwork panel is manufactured by a secondary process that requires cutting the plywood and cutting and reattaching the manufactured plywood. In addition, since the conventional formwork panel is made only of wood, it is expensive and expensive Since it is usually stored in open air, it absorbs moisture when it rains, so it should be used in such a state that the strength is lowered in a dry state.
이러한 단점을 어느정도 배제하고자하여 합판(1)의 표면에 코올타르를 피복하는 등의 임시방편의 조치를 취하여 사용하고 있으나 이 역시 상기한 문제점을 완전히 해결하지 못하여 결국 높은 제조원가를 제공하고 있음에도 불구하고 목재의 문제점 등에 의한 사용상제약이 많았다.In order to rule out this disadvantage to some extent, we have used temporary measures such as coating the coal tar on the surface of the plywood (1), but this also does not completely solve the above problems, but in spite of providing high manufacturing cost There were many usage restrictions due to problems.
그리고 근래에 이르러서는 옹벽(콘크리트벽)의 단조로움을 피하기 위하여 옹벽에 각종 문양을 넣은 상태로 시공하는데 이때 거푸집판넬을 상기한 바와같이 목재로 되어있기 때문에 문양을 넣어 콘크리트를 타설할 수 없었다.In recent years, in order to avoid the monotony of the retaining wall (concrete wall), it is constructed with various patterns in the retaining wall. At this time, since the form panel is made of wood as described above, it was not possible to pour concrete into the pattern.
이러한 문제점을 해결하고자하여 발포수지(일명 스치로폴수지)로 각종 문양을 만들어 연속문양이 나타나도록 이용하고 있으나, 이 발포수지에 의한 문양은 재사용이 불가능하여 비경제적인 단점이 있다.In order to solve this problem, various patterns are made of foamed resin (also known as styropol resin), so that the continuous pattern appears. However, the pattern by the foamed resin cannot be reused, which is uneconomical disadvantage.
본 발명은 이러한 종래의 거푸집판넬이 가지는 문제점을 감안하여 높은 강도와 낮은 가격의 거푸집판넬을 제공하되, 제조되는 거퍼집판넬은 산업폐기물 중에서도 소각 등 폐기가 어려운 폐타이어, 폐고무, 봉제 등 섬유류로 의목을 제조하는 의류공장에서 나오는 섬유스크랩 또는 피혁을 이용하여 각종 가죽제품을 제조하는 공장에서 나오는 절단가죽조각, 스폰지조각, 제지공장에서 필히 나오는 제지스퍼지, 목재 제재소에서 나오는 톱밥 등의 산업폐기물을 이용하여 일정한 두께와 크기를 가진 높은 강도의 거푸집판넬을 제공하고자 하는데 그 목적이 있다.The present invention provides a high strength and low price formwork panel in view of the problems of the conventional formwork panel, the manufactured formwork panel is a waste tire, waste rubber, sewing, such as incineration among industrial wastes Industrial wastes such as cutting leather pieces, sponge pieces, paper spurs from paper mills, sawdust from wood mills, etc. The purpose is to provide a high strength formwork panel with a constant thickness and size.
또한, 상기한 산업폐기물을 본 발명에 의해 성형할 때, 음·양각으로 각종 문양을 넣어 성형하므로서, 콘크리트타설시 옹벽의 표면에 성형된 문양이 그대로 표출될 수 있도록 하여 아름다운 옹벽을 갖추되 기 성형된 문양이 있는 거푸집판넬을 장기간 계속하여 사용할 수 있도록 하는데 그 부목적이 있다.In addition, when molding the industrial wastes according to the present invention, by inserting a variety of patterns in the negative, embossed, so that the molded pattern on the surface of the retaining wall can be expressed as it is when the concrete is placed to form a beautiful retaining wall Its sub-objective is to provide continuous use of patterned formwork panels.
이러한 목적을 달성하기 위해 본 발명에서는 상기한 바와같이 각종 산업폐기물을 이용하게 되는데, 그 주된 이유는 폐기타이어 및 폐고무는 그 재질 특성상 연성과 탄성율이 높아 완제품의 성형시 어느정도의 휨에 서도 견딜수 있도록 한 탄성을 주고자 하는데 있고, 섬유조각 및 가죽조각은 그 재질 특성상 인장강도 즉 질기기 때문에 완제품 성형시 절단 등에서 견딜 수 잇도록 하는데 있고, 제지스러지 및 톱밥은 목재의 섬유질에 의한 탄성과 강도를 유지하면서 경량성을 유지하도록 하는데 그 목적이 있다.In order to achieve this object, in the present invention, various industrial wastes are used as described above. The main reason is that waste tires and waste rubber have high ductility and elastic modulus in their material properties, so that they can withstand a certain degree of warpage during molding of the finished product. In order to give a elasticity, the fiber pieces and leather pieces are able to withstand the tensile strength, that is, the toughness due to their material characteristics, so that they can be cut during molding of the finished product. The purpose is to maintain lightweight while maintaining.
이러한 산업폐기물을 이용하고 있는 본 발명에서의 그 제조방법에 대하여 구체적으로 설명하면 다음과 같다.Referring to the production method in the present invention using such industrial wastes in detail as follows.
폐기타이어, 폐고무(이하 폐고무재라 함), 천(섬유), 가죽(이하 폐피혁재라 함)등은 1~3mm의 크기로 잘게 분쇄하는 분쇄공정으로 취한다.Waste tires, waste rubber (hereinafter referred to as waste rubber material), cloth (fiber), leather (hereinafter called as leather waste) are taken as a pulverizing process that is finely crushed to a size of 1 to 3 mm.
이러한 분쇄공정에 의할 때 3mm이상의 크기로 분쇄하면 산업폐기물간의 응집력이 떨어지는 문제점이 발생되므로 3mm이하의 크기로 분쇄한다.When crushing to a size of 3mm or more due to such a crushing process, the cohesive force between industrial waste is reduced, so crushed to a size of 3mm or less.
이렇게 분쇄공정에 1~3mm의 크기로 분쇄된 분쇄물인 폐고무재와의 혼합비율을 1 : 1로 혼합하는 제1혼합물을 만들거나, 폐고무재, 폐피혁재, 제지스러지, 톱밥(이하 폐목재질이라 함)의 혼합비율을 5 : 3 : 2의 비율로 혼합하는 제2혼합물을 만드는 혼합공정을 취한다.In the crushing process, the first mixture is made by mixing the mixing ratio with the waste rubber material, which is pulverized to a size of 1 to 3 mm in a ratio of 1: 1, or used rubber material, waste leather material, paper waste, sawdust (hereinafter referred to as Take a mixing process to make a second mixture in which the mixing ratio of the waste wood material) is mixed at a ratio of 5: 3: 2.
이러한 폐산업폐기물로 이루어진 제1 또는 제2혼합물 60~80wt%, 요소수지 30~17wt%, 멜라민수지 10~3wt%를 혼합기에 넣어 완전히 혼합하는 혼화공정을 취한다.60-80 wt% of the first or second mixture consisting of these waste industrial wastes, 30-17 wt% of urea resin, and 10-3 wt% of melamine resin are mixed in a mixer to take a mixing process.
이러한 혼화공정에서 얻어지는 혼화물을 컨베이어를 통하여 일정한 간격을 두고 상·하에서 설치된 가공로울러를 통과시켜주는 가공공정을 취한다. 이러한 가공공정을 취한다음 일정한 두께(가공로울러가 이격설치된위치만큼의 크기)를 가진 반가공물을 150℃~220℃의 연속가열도를 통과시켜 완성품을 얻는 완성공정을 취한다음 일정한 규정으로 절단하는 절단공정을 연속적으로 취하여 본 발명에 의한 거푸집판넬을 얻는다.It takes a processing step that passes the mixed roller obtained in such a mixing process through the processing rollers installed at the top and bottom at regular intervals through the conveyor. After taking these processing steps, a semi-finished product with a certain thickness (as much as the position where the processing roller is spaced apart) is passed through the continuous heating degree of 150 ℃ ~ 220 ℃ to take the finishing process to get the finished product. The process is taken continuously to obtain a formwork panel according to the present invention.
이러한 상기의 제1혼합물에서 폐고무재와 폐피혁재를 1 : 1로 혼합하는 것을 폐고무재의 연성, 탄성유지와 폐피혁재의 인장(질김)문제를 동시에 해결하기 위해 동일한 비율로 혼합물을 얻는 것이고, 제2혼합물에서 폐고무재, 폐피혁재, 폐목재질이 5:3:2로 혼합되는 것을 폐목재질은 그 자체의 섬유질에 dlm한 인장이 있으나 가볍기 때문에 폐피혁재의 대체용으로 이용하는데 있다.Mixing the waste rubber material and the waste leather in a ratio of 1: 1 in the above first mixture is to obtain a mixture at the same ratio in order to solve the problems of ductility, elasticity of the waste rubber and tension (toughness) of the waste leather at the same time. In the second mixture, waste rubber material, waste leather material, and waste wood material are mixed at 5: 3: 2, and the waste wood material is used as a substitute for waste leather material because of its tensile strength but lightness.
그러나, 이러한 혼합물의 비율은 꼭 그렇게 해야한다는 것이 아니고, 필요에 따라 다소 변경이 될 수 있음을 지적하고 싶다.However, I would like to point out that the proportions of these mixtures are not necessarily so, but can be changed somewhat as needed.
이러한 제1혼합물 또는 제2혼합물 60~80wt%에 요소수지 30~17wt%, 멜리민수지 10~30wt%를 혼화하는 혼화공정에 있어서, 상기한 성형완성품 제조공정시에 가공로울러를 통과하면서 압축될 때에도 상기한 요소수지가 열가형성수지이기 때문에 가공로울러와의 마찰열에 의해 완제품의 형상에 흐트러짐이 없어져야 할 뿐만 아니라 연속가열로에서 가열성형될 때도 그 형상에 흐트러짐이 없어져야 한다.In the blending process of blending the urea resin 30-17 wt% and the melamine resin 10-30 wt% with the first or second mixture 60-80 wt%, the compacted material may be compressed while passing through the processing roller during the manufacturing process of the molded article. In this case, since the urea resin is a thermoformable resin, the shape of the finished product should not be disturbed by the frictional heat with the processing roller, and the shape of the urea resin should be eliminated even when heated in a continuous heating furnace.
따라서, 상기한 요수수지의 혼화율이 전체 wt%에서 30wt%이상이 되면 비교적 고가인 요소수지를 많이 이용할 이유는 없거니와 성형후 겉부분은 즉시 응고는 되나 내부는 미쳐 응고가 일어나지 아니하므로 성형 시간이 너무 많이 걸리는 단점이 있었고, 전제 wt%에서 17wt%이하가 되면 제1혼합물 또는 제2혼합물의 응집력이 떨어져서 결국 강도, 인장력 등이 크게 떨어지는 단점이 있었다.Therefore, if the mixing ratio of the urea resin is more than 30wt% in the total wt%, there is no reason to use a relatively expensive urea resin, but since the outer part is solidified immediately after forming, but the inside is not coagulated, molding time There was a disadvantage that takes too much, when the wt% or less at the premise wt%, the cohesive force of the first mixture or the second mixture was dropped and eventually the strength, tensile strength, etc. were greatly reduced.
또한 혼화되는 멜라민수지의 혼화율이 전제 wt%에서 10wt%이상이 되게되면 완제품의 강도가 너무 크게 되어 탄성유지가 어렵게 되어 충격에 의해 쉽게 깨질 우려가 있고, 전체 wt%에서 3wt%이하로 혼화하게 되면 방수능력이 떨어지는 단점이 있다.In addition, when the blending ratio of the melamine resin blended becomes more than 10wt% at the premise wt%, the strength of the finished product becomes too large, making it difficult to maintain elasticity, and it may be easily broken by the impact, and blends below 3wt% at the total wt%. If there is a disadvantage that the waterproof ability.
이러한 것은 결국 상기한 혼화물을 압축한 후에 서로의 형상유지 및 강도유지를 위해 가열되어질때의 열이 180℃가 되면 혼화물이 서로 응집 또는 형상의 성형이 거의 일어나지 아니하여 부서져 버리는 반면에 220℃이상이 되면 요수수지가 용해되어버려 제1,2혼합물의 응집력이 떨어져 충분한 강도유지가 불가능한 단점을 나타내었다.In the end, when the heat is heated to 180 ° C. after compressing the above-mentioned admixtures to maintain shape and strength of each other, the admixtures are broken with little flocculation or shaping of each other. When the abnormalities were found, the urea resin was dissolved and the cohesive strength of the first and second mixtures was low, indicating that the sufficient strength was not maintained.
이러한 본 발명의 상기한 성형완성품 제조공정시에는 가공로울러의 표면에 혼화물을 성형하게 되면 성형물인 완성품의 일표면에 가공로울러 형성된 모양이 그대로 음·양각 형태로 표출되게 되는 효과를 구득할 수 있게 된다.In the manufacturing process of the finished molded article of the present invention, when the blend is molded on the surface of the processed roller, the shape formed by the processed roller on one surface of the finished product, which is a molded product, can be obtained as it is, in the form of negative and embossed shapes. do.
이러한 본 발명의 방법에 의해 제조되는 거푸집판넬은 첨부한 도면 제2도와 같은 형태로 성형하게 되는데 일측내측면에도 요철부(10)를 두어 강도유지와 함께 그 타측면에는 문양(11)을 표현하여 줌으로써 옹벽의 미감을 표출할 수 있게 되는 효과를 구득할 수 있게 된다.Formwork panel manufactured by the method of the present invention is to be molded in the form as shown in Figure 2 attached to the uneven portion 10 on one side inner surface to maintain the strength and to express the pattern 11 on the other side By giving it, the effect of being able to express the aesthetics of the retaining wall can be obtained.
이러한 본 발명에 의해 제조된 거푸집판넬과 종래에 이용되었던 목재로 된 거푸집판넬과 서로 휨강도(휘어서 파손될 때의 강도)에 의한 품질비교 분석을 하여본 결과 본 발명에 의한 거푸집판넬이 휨 즉 탄성도와 강도가 높은 우수한 품질을 가지고 있는 것을 알 수 있었다.As a result of analyzing the quality comparison by the formwork panel manufactured according to the present invention and the formwork panel made of wood and the bending strength (strength when broken), the formwork panel according to the present invention is warped, that is, elasticity and strength. It can be seen that has a high excellent quality.
