본 발명은 비늘모양 또는 잎모양의 결정이 집합하여 된 운모광물의 하나로서 가열하면 팽창하는 성질이 있고 경량성, 내화성, 단열성, 흡음성등이 있는 질석을 이용하여 견고하고 일정한 두께를 유지하는 건축용 판넬을 효과적으로 제조할수 있는 건축용 판넬의 제조방법에 관한 것이다.The present invention is one of the mica minerals in which the scaly or leaf-shaped crystals are collected and expands when heated, and the building panel maintains a solid and constant thickness using vermiculite having light weight, fire resistance, heat insulation, sound absorption, and the like. It relates to a method for manufacturing a building panel that can be effectively manufactured.

일반적으로 질석(蛭石)은 운모광물의 하나로서 화학조성식은 Mg, Fe3+, Al3(Al,Si)4O10, (OH)2,4H2O로 되어 있으며 바늘모양 또는 잎모양의 결정이 집합된 단사 결정계로서 가열하면 층사이에 있던 수분이 증기로 변하며 격자층이 부풀어 오르는 등 부피가 증가하는 성질을 지니고 있고 가볍고 내화성이 있고 흡음및 단열충전재로도 많이 사용되고 있으며 독성이 없는 자연친화적인 물질이다.In general, vermiculite is one of the mica minerals. The chemical formula is Mg, Fe 3+ , Al 3 (Al, Si) 4 O 10, (OH) 2 , 4H 2 O, and needle or leaf shape. It is a monoclinic crystal system in which crystals are aggregated, and when heated, the moisture between layers becomes vapor and the lattice layer swells. Phosphorus substance.

그러나 종래에는 질석을 이용하여 건축용 판넬을 제조하는 경우에 질석을 잘게 분쇄시킨다음 분쇄물을 소성하여 발포시킨 상태의 질석알갱이와 무기물접착제를 혼합한 혼합물을 성형틀내에 투입하여 성형하고 이를 건조시키는 방법으로 제조하고 있으나 성형틀에서 수분이 빠져나가고 건조가 용이하도록 성형틀 일부를 개구시킨 상태이므로 건조과정에서 판넬이 뒤틀리는 등 형태변형이 생길 뿐만 아니라 성형틀의 개구부 부분은 과도하게 건조되고 내부및 나머지 부분은 건조상태가 좋지 못하여 결착력이 크게 떨어지게 되므로 견고한 판넬을 구성할수 없었으므로 주로 충전재로 이용 되었으며 바닥재등의 판넬로는 사용되지 못하였다.
However, in the prior art, when preparing a building panel using vermiculite, the vermiculite is pulverized finely, and then a mixture of the vermiculite grains and the inorganic adhesive in the form of sintering and foaming the pulverized product is put into a molding mold and dried. However, since part of the mold is opened to allow moisture to escape from the mold and to be easily dried, the deformation of the mold occurs, such as the panel being distorted during the drying process, and the opening part of the mold is excessively dried and the interior and the rest of the mold. Because of poor drying condition, the binding force was greatly decreased, so it was not used as a filling material and could not be used as a flooring material.

본 발명은 이러한 문제점을 해결하기 위하여 발포된 질석알갱이와 무기물 접착제를 혼합한 혼합물을 성형틀에 투입하여 성형틀을 완전커버시킨 상태에서 건조시키되 성형틀의 상,하부 금형에 관통시킨 다수의 미세구멍을 통해 수분배출이 됨과 아울러 마이크로웨이브를 이용한 건조수단으로 균일하게 건조가 되고 건조과정에서 변형되지 않도록 한 것이다.In order to solve this problem, a mixture of foamed vermiculite grains and an inorganic adhesive is added to a molding mold and dried in a state in which the molding mold is completely covered, but a plurality of micropores penetrated through upper and lower molds of the molding mold. The water is discharged through the drying means using the microwave and is uniformly dried to prevent deformation during the drying process.

또, 상기의 마이크로웨이브에 의한 건조시에 건조실내에 다수의 성형틀을 순차공급하여 대량생산이 용이하도록 한 것이다.
In addition, a large number of molds are sequentially supplied into the drying chamber during drying by the microwave to facilitate mass production.
