Abstract

본 발명은 제철공장의 부산물인 수쇄슬래그를 이용하여 경량의 단열재를 제조하는 방법에 관한 것으로서, 수쇄슬래그 5~20중량%, 퍼얼라이트 ; 70~85중량%, 규산소오다 5~15중량%가 되도록 원료를 배합하고, 이 원료에 수분을 첨가하여 혼합한 후 통상의 가압성형 방법으로 성형체를 제조하고 건조한 후, 소성온도 850~950℃에서 30분간 가열하여 소성시키는 것을 특징으로 하는 경량 단열재 제조방법이다.The present invention relates to a method for producing a lightweight heat insulating material using the hydrothermal slag which is a by-product of an iron making plant, the hydrocracking slag 5 to 20% by weight, pearlite; The raw materials are blended so as to be 70 to 85% by weight and 5 to 15% by weight of sodium silicate, and water is added to and mixed with the raw materials. It is a method of manufacturing a lightweight heat insulating material, characterized in that the heating for 30 minutes in the firing.
