Abstract: 본 발명은 일반적으로 사용되어 지는 판유리, 병유리 등의 파쇄분 폐유리를 이용하여 발포유리를 제조하는 것으로 기공 형성을 위한 첨가물 없이 폐유리를 직접 발포시키는 방법에 관한 것이다. 본 발명에서 사용하는 발포용 원료분말은 폐유리를 이용하여 분쇄공정을 통하여 얻어진다.
습식 분쇄공정에 있어 용매로는 물, 에틸 알코올, 메틸 알코올, 아세톤 등을 이용하였으며, 분쇄된 분말은 성형몰드에 체밀 충전하여 일축 또는 정수압 성형을 행한 후, 600～1000℃의 온도구간에서 발포시켰으며, 발포공정 후 만들어진 발포유리는 심미성 및 균일한 미세 기공구조를 가지는 발포유리를 제조하였다.
발포유리의 기본적인 물성은 287 ㎏/㎥의 밀도 값과 88%의 기공율, 1.4 MPa의 압축강도, 그리고 25℃에서 0.070 kcal/mh℃ 열전도도를 나타내는 특성을 나타내었다. 이와 같은 본 발명은 건축용 경량 내화재, 방음재 등으로 이용되고 경량이어서 취급이 용이하다.-

Abstract: PURPOSE: A method for manufacturing foamed glass using waste glass is provided to obtain the foamed glass by implementing a pulverizing process and a pyrolyzing process without the addition of a pore forming agent. CONSTITUTION: Sodium and boro alumino-silicate-based waste glass is prepared as a starting material for foamed glass. The waste glass is pulverized to be of a size between 1 and 10um. The pulverized waste glass powder is milled for 1-72 hours. The milled waste glass powder is compressed in a mold without the addition of a foaming agent to obtain a molded body. The molded body is sintered and foamed at a temperature between 600 and 1000°C. The density of the foamed glass is 287kg/m^3. The porosity of the foamed glass is 88%. The compressive intensity of the foamed glass is 1.4MPa. The thermal conductivity of the foamed glass at 25°C is 0.070kcal/mh°C.
