본 발명은 펄라이트를 이용한 다기능, 다공질 세라믹 형상을 갖는 건축자재의 제조방법에 관한 것으로서, 더욱 상세하게는 펄라이트를 주재료로 건축자재 생산함으로서, 경량성, 불연성, 흡음성 및 단열보온성이 우수하여 소비자의 구매욕구를 충족시킬 수 있는 펄라이트를 이용한 다기능, 다공질 세라믹 형상을 갖는 건축자재의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a building material having a multi-functional, porous ceramic shape using pearlite, and more specifically, by producing a building material of pearlite as a main material, it is excellent in light weight, nonflammability, sound absorption and thermal insulation, and can be purchased by consumers. The present invention relates to a method of manufacturing a building material having a multifunctional, porous ceramic shape using pearlite that can satisfy a desire.
일반적으로, 생활수준의 향상과 지식산업의 고도화 및 정보화 사회의 급변하는 환경에 대응하는 주거공간의 절대 필요에 따라 날로 건축물의 대형화, 첨단화, 기능화가 요구되는 현실에서 건축물 예를 들면 아파트, 복합상가 등의 고층화, 대형화는 필연적인 현상이다. 이에 건축자재의 경량, 불연, 방음, 단열보온을 동시에 충족시켜주는 소재를 개발하기 위한 연구, 노력은 지속되어 왔으며, 이러한 요구에 부응하여 다공질의 건축자재가 여러 분야에서 개발되고 있는 실정이다.In general, buildings such as apartments and complex shopping malls are required in the reality that large scale, advanced and functionalization of buildings are required in accordance with the improvement of living standards, the advancement of the knowledge industry, and the absolute necessity of living spaces corresponding to the rapidly changing environment of the information society. Higher and larger scales are inevitable. Accordingly, researches and efforts to develop materials that satisfy light weight, nonflammability, sound insulation, and thermal insulation at the same time have been continued. In response to these demands, porous building materials are being developed in various fields.
지금까지 개발된 건축자재들은 스티로폼, 우레탄, 석면 또는 석고보드 등으로 제작되고 있으나, 전술한 건축자재들은 경량성, 불연성, 방음성, 단열보온성 모두를 충족시키지 못하는 문제점이 있었다. 먼저, 스티로폼 및 우레탄으로 제작된 우레탄 폼은 내부의 공기로 인해 외부의 찬공기는 방어하고 내부의 열기는 외부로 차단하는 보온성이 뛰어나며 반면, 여름에는 외부의 더운공기를 막아줌으로써, 외부와 내부의 온도차로 실내가 시원해지는 효과가 있으나, 비교적 열에 약한 문제점이 있어 화재시 유독성 가스 분출로 인명피해가 매우 높으며, 우레탄 폼 역시 스티로폼에 비해선 점화속도가 낮으나 발화후에는 검은연기와 가스가 배출되며 중량이 무거운 문제점이 있다.The building materials developed so far are made of styrofoam, urethane, asbestos or gypsum board, but the above-described building materials have a problem that does not satisfy all of light weight, nonflammability, sound insulation, and thermal insulation. First, the urethane foam made of styrofoam and urethane is excellent in thermal insulation, which protects cold air from outside and blocks heat from the outside due to the air inside, while preventing the outside hot air in summer. The effect is that the indoors are cool due to temperature difference, but there is a relatively weak problem in heat, which causes very high casualties due to the release of toxic gases in the fire. There is a heavy problem.
한편, 석면은 마그네슘과 규소를 포함하고 있는 광물질로서 솜과 같이 부드러운 섬유질로 되어 있고, 내화성이 강하고 마찰에 잘 견딜 수 있으며 화학약품에 대한 저항성, 전기에 대한 절연성이 우수하나 석면에서 발생하는 먼지는 사람에게 암과 같은 질병을 유발시킬 뿐만 아니라 물에 젖으면 무게가 무거워져 작업성이 떨어지는 문제점이 있었으며, 석고보드는 단열성 및 보온성을 우수한 불연재임에는 틀림없으나 그 자체 무게가 무겁고 물에 젖으면 부서지는 문제점이 있었다.On the other hand, asbestos is a mineral containing magnesium and silicon. It is made of soft fiber like cotton, has strong fire resistance, can withstand friction, and has excellent resistance to chemicals and insulation against electricity. In addition to causing diseases such as cancer to humans, there is a problem in that workability is poor because the weight is heavy when wet, and the gypsum board must be a non-flammable material excellent in insulation and heat insulation, but the weight itself is heavy and broken when wet There was a problem.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 펄라이트를 주재료로 건축자재 생산함으로서, 경량성, 불연성, 흡음성 및 단열보온성이 우수하여 소비자의 구매욕구를 충족시킬 수 있는 펄라이트를 이용한 다기능, 다공질 세라믹 형상을 갖는 건축자재의 제조방법을 제공하는데 있다.The present invention has been made to solve the conventional problems as described above, the object of the present invention is to produce a building material of pearlite as a main material, to meet the consumer's purchase needs to excellent light weight, nonflammability, sound absorption and thermal insulation insulation It is to provide a method of manufacturing a building material having a multifunctional, porous ceramic shape using a pearlite.
