Abstract
본 발명은 비교적 경량질의 건축용 패널을 제조함에 있어서 코아층을 형성하는 충전물질을 펄라이트, 플라스틱폼 등의 경량골재의 파쇄분과 경질탄산칼슘 등의 필러, 발전소 연돌 속의 폐분진인 플라이애시, 도장후 회수되는 분체도료의 폐기분말 등을 열경화성의 페놀수지분말과 혼합한 것을 에스엠씨(SMC)판으로 된 상하 샌드위치 기판 사이에 충전하여 열간 프레스로 가압, 용융성형한 바닥재 겸용 벽판용 패널의 제조방법이다.According to the present invention, in the manufacture of a relatively lightweight building panel, the filling material forming the core layer is divided into crushed powder of light aggregate such as pearlite and plastic foam, filler such as hard calcium carbonate, fly ash which is waste dust in the power plant stack, and recovery after coating. It is a method of manufacturing a flooring combined wall panel panel which is mixed with a waste powder of a powder coating and the like and a thermosetting phenolic resin powder is sandwiched between upper and lower sandwich substrates of SMC plates and pressurized by hot press.
종래의 이와같은 목적으로 제조된 패널은 경석을 충전재로 하고 상하기판용 열경화수지에는 발포제를 사용하여 패널을 경량화 하였으나 제조시 사용되는 발포제는 제조시 유출되는 유해물질로 인하여 작업자에게 호흡장애 등의 위험이 있었다.Conventionally, the panel manufactured for this purpose is made of pumice as a filler and the panel is lightened by using a blowing agent in the thermosetting resin for the upper and lower substrates. There was a danger.
본 발명은 이와같은 종래의 건축용 패널의 문제점을 해결하기 위하여 경화제 또는 발포제를 사용하지 않는 열경화성수지와 플라이애시, 분체도료 폐기분, 경탄, 경량골재의 파쇄분과 혼합하여 에스엠씨 판재 사이에 충전, 열간 프레스로 제조하는 비교적 간단한 제조방법을 제공한 것으로 상하기판이 사전에 성형된 공지의 에스엠씨로 된 시이트상 이므로 층간 물질인 코아의 충전공정이 간단하다.In order to solve the problems of the conventional building panels, the present invention is mixed with a thermosetting resin and a fly ash, powder ash waste, hard coal, light aggregate crushed powder without using a curing agent or foaming agent to fill, hot It provides a relatively simple method of manufacturing by pressing, and the filling process of core, which is an interlayer material, is simple because the upper and lower substrates are sheet-forms of known SMCs which have been molded in advance.
이와같이 된 본 발명은 상하기판 사이에 무기질 경량골재와 전술한 코아성형 물질을 열경화성수지와 혼합하여 충전, 열압, 층착한 것이므로 고강도, 경량성, 가공성, 내화성이 우수한 바닥재, 벽재용도의 복합 패널이다.Thus, the present invention is a composite panel of high strength, light weight, workability, fire resistance, and composite panels, because the inorganic lightweight aggregate and the core-forming material is mixed, filled with thermosetting resin, and laminated between the upper and lower boards.
Description
본 발명은 바닥재와 벽재를 사용 할 수 있는 건축용 패널을 제조함에 있어서 열경화성수지로 된 상하 샌드위치 기판 사이에 층간 충전재로 경량골재, 플라이 애시, 폐기도료분말, 필러 등을 혼합하여 열간프레스로 성형한 복합구조의 패널을 제공한 것이다.The present invention is a composite of a lightweight aggregate, fly ash, waste paint powder, filler, etc. as an interlayer filler between the upper and lower sandwich substrate made of a thermosetting resin in the manufacture of a building panel that can use the flooring and wall materials formed by hot press It provides a panel of structures.
종래에 이와같은 목적으로 제조된 패널은 경석을 주재로 각종 수지에 무기질 섬유를 보강한 것으로, 치수 안정성이 우수한 경량의 패널이 제조되고 있으나, 경량을 위해 상하 표층용 열경화수지에 발포제를 사용하므로서 내화성은 없지만 시공성이 좋아 빙화성을 요하지 않는 장소의 천정, 벽재 등에 방음재, 차음재, 방진재 등으로 사용되고 있으나, 제조시 사용되는 발포제는 제조시 작업자의 건강에 위험이 있는 유해물질일 뿐만 아니라 제조공정에서도 온도관리가 정확치 못 할 경우 바포제중의 톨루엔, 디페닐메틸이소시아네이트 성분의 유출로 호흡장애 등의 위험이 있었다. 또 다른 종류로는 패널의 강도증대와 불연성을 위하여 플라이 애시등 폐기물을 사용한 바닥재가 고강도, 경량, 불연성 및 원적외선 방사용으로 철재, 목재, 바닥재의 대용으로 공지되고 있으나 강도에 비해 전단력이 약하여 바닥재의 효용에는 부적합 하였고 원적외선 방사에도 특성이 없었다.Conventionally, the panel manufactured for this purpose is to reinforce inorganic fibers in various resins mainly based on pumice, and to manufacture lightweight panels with excellent dimensional stability, but by using a foaming agent in upper and lower surface thermosetting resins for light weight. Although it is not fireproof, it is used as a soundproofing material, soundproofing material, and dustproofing material in ceilings, walls, etc. where it does not require ice resistance because of its workability. If the temperature control is not accurate, the leakage of toluene and diphenylmethyl isocyanate components in the foaming agent may cause respiratory disorders. Another type of flooring using waste ash such as fly ash for increased strength and non-combustibility of panels is known as a substitute for steel, wood, and flooring for high strength, light weight, non-combustibility and far infrared radiation. It was unsuitable for utility and had no characteristics in far infrared radiation.
유리섬유 내장 패널은 멜라민, 페놀, 요소수지 등을 유리단섬유에 분무한 후 열간 프레스로 가압성형하여 층착한 것으로 접착되는 상하기판 제조시 사용하는 이 형재의 영향으로 접착성이 좋지 않고 표면의 평활성이 부족한 것도 있었고, 유리단섬유를 별도의 접착공정 없이 속경화성 페놀수지로 함침 건조 시킨 후 가압 가열하는 방법등이 공지 되었다.Glass-fiber embedded panel is made by spraying melamine, phenol, urea resin, etc. on short glass fiber and press-molded by hot press to form a laminate. There was also a shortage, and a method of impregnating and drying the short glass fibers with a fast curing phenol resin without a separate bonding process, and then pressurized heating is known.
본 발명 이와같은 종래의 패널의 문제점과 결함을 해결하기 위하여 경화제 또는 발포제를 사용하지 않는 열경화성수지, 발전소 연돌 속의 미연소 폐자원인 탄화분 플라이애시, 분체도료의 도장 후 회수되는 폐기분말, 필러로서 경질탄산칼슘, 경량골재의 파쇄분과 혼합하여 에스엠씨 (SMC : Sheet Moulding Compound) 판재 사이에 충전하여 열간 프레스로 제조하는 비교적 간단한 방법으로서 이 방법은 상하판재가 시트상이므로 층간재인 충전공정이 간단하다.In order to solve the problems and defects of the conventional panel, a thermosetting resin which does not use a curing agent or a foaming agent, a carbonaceous fly ash, which is an unburned waste resource in a power plant stack, a waste powder and a filler recovered after the coating of powder coating It is a relatively simple method that is mixed with crushed powder of hard calcium carbonate and light weight aggregate and filled between sheet molding compounds (SMC) and manufactured by hot press. This method is simple because the upper and lower plates are in the form of sheets. .
본 발명에서 사용되는 수지는 열경화성 페놀수지 외 불포화 폴리에스테르수지, 폴리우레탄수지, 에폭시수지 등을 사용할 수 있고 경량골재로는 펄라이트, 버미큐라이트, 슬레그, 플라스틱, 발포체인 우레아 폼, 페놀 폼, 점토혼합 플라이 애쉬등이며, 필러로는 경질탄산칼슘, 그 외내화재로는 돌로마이트 클링커, 마그네시아 클링커등에서 선별 사용한다.The resin used in the present invention may be a thermosetting phenol resin, unsaturated polyester resins, polyurethane resins, epoxy resins, and the like. As lightweight aggregates, pearlite, vermiculite, slag, plastic, foamed urea foam, phenolic foam, Clay-mixed fly ash and the like, used as filler in hard calcium carbonate, and other refractory materials in dolomite clinker and magnesia clinker.
본 발명에서 기술적 과제를 종래의 방법과 대비하면 본 발명은 강화 플라스틱인 에스엠씨(SMC) 판재를 샌드위치용 패널로 도입하여 패널의 용도와 요구되는 품질수준에 따라 에스엠씨의 품질규격을 할 수 있다.In contrast with the conventional method in the present invention, the present invention can be introduced to the SMMC (SMC) plate material of reinforced plastic as a panel for sandwich can be the quality standard of SM according to the use of the panel and the required quality level. .
종래에는 에스엠씨로 된 샌드위치 패널 대신 금형내에서 수지분말을 일정 두께로 도포한 위에 각종 무기섬유를 살포하고 경량골재와 수지분말을 혼합한 충전재를 포설 한 후 다시 수지분말과 강화용 무기섬유를 살포하여 열간 압축하여 층착된 샌드위치 패널을 성형한 것으로, 제조시 성형품질의 수준을 조정 할 수 있는 작업자의 재량이 없고, 작업공정이 늘어나서 성형품질이 일정하지 못하므로서 건축용 패널로서 용도별 수요수준을 쉬이 제공 할 수 없었다.Conventionally, instead of the sandwich panel made of SMC, various inorganic fibers are sprayed on the mold by applying a resin powder in a predetermined thickness, and then a resin powder and a reinforcing inorganic fiber are sprayed again after the filling material is mixed with light aggregate and resin powder. It is molded by sandwiching the sandwich panel by hot compression, and there is no worker's discretion to adjust the level of molding quality during manufacturing, and it is easy to provide demand level for each application as a building panel because the work quality is not constant and molding quality is not constant. I could not.
그러나 본 발명은 비교되는 패널에 비해 작업공정이 단순화 되었고 특히 조성의 변화를 부여한 환경 친화형 이므로 용도별 목적에 따른 광법위한 효용을 기대 할 수 있다.However, the present invention has a simplified work process compared to the panel to be compared, and in particular, since it is an environment-friendly type that gives a change in composition, it can be expected to be useful for light method according to the purpose of each use.
첨부도면은 패널의 복합단면 형성공정을 보인 예시도.The accompanying drawings show an example of the composite cross section forming process of the panel.

종래의 건축 패널용 열경화성수지는 경량화를 위하여 발포제를 혼합하여 경화 하므로서 성형시 유해물질의 유출 위험이 있었으나, 본 발명은 발포제를 사용하지 않고 페놀수지분말과 상기한 경량골재, 플라이애시, 분체도료 폐기분말을 균일하게 혼합하여 층간 충전재로 사용하였고 또 샌드위치용 상하기판은 에스엠씨의 두께로 균일하게 조절 할 수 있으므로 열간 압축성형이 용이한 샌드위치 구조의 복합패널을 제조할 수 있다.Conventional thermosetting resin for building panels has a risk of spillage of harmful substances during molding by mixing and curing the foaming agent to reduce the weight, but the present invention discards the phenolic resin powder and the above-mentioned lightweight aggregate, fly ash, powder coating without using a blowing agent. The powder was uniformly mixed and used as an interlayer filler, and the upper and lower substrates for sandwiches can be uniformly controlled by the thickness of SMC, so that a composite panel having a sandwich structure can be manufactured easily with hot compression molding.
