HEAT INSULATION MONOLITHIC REFRACTORY
PROBLEM TO BE SOLVED: To provide a heat insulation monolithic refractory capable of uniformly dispersing gaps (pores) into a refractory without using a foam agent.SOLUTION: Provided is a heat insulation monolithic refractory obtained by adding water to a blend of a refractory material and an additive. As the additive, a material eluting lignin is added by 0.3 to 5 mass% to the refractory material, a surfactant is added by 0.001 to 0.2 mass% to the refractory material, the addition amount of water is controlled to 35 to 60 mass% to the blend, and its bulk density when being cured at ordinary temperature for 24 hr and dried at 110°C for 24 hr is 1.6 or lower.SELECTED DRAWING: None
【課題】発泡剤を用いることなく耐火物内部に空隙（気孔）を均一に分散させることができる断熱不定形耐火物の提供。【解決手段】耐火材料と添加剤との配合物に水を添加してなる断熱不定形耐火物において、前記添加剤として、リグニンを溶出する材料を前記耐火材料に対して０．３〜５質量％、界面活性剤を前記耐火材料に対して０．００１〜０.２質量％添加し、水の添加量は、前記配合物に対して３５〜６０質量％とし、常温で２４時間養生して１１０℃で２４時間乾燥したときのかさ比重が、１．６以下である断熱不定形耐火物。【選択図】なし
