Plastic refractory for repairing furnace lining of intermediate frequency furnace and preparation method of plastic refractory
The invention discloses a plastic refractory for repairing a furnace lining of an intermediate frequency furnace and a preparation method thereof, and belongs to the technical field of refractory materials for intermediate frequency furnaces. The plastic refractory comprises the following components in percentage: 20%-30% of alumina, 35%-45% of mullite, 5%-15% of kyanite, 5%-10% of a plasticizer, 3%-7% of glucose, 2%-5% of silicon nitride and 10%-15% of modified aluminum polyphosphate. Wherein the modified aluminum polyphosphate is prepared by the following method: reacting aluminum polyphosphate, silica powder, polyvinyl alcohol and water at 180-220 DEG C, and cooling to room temperature to obtain the modified aluminum polyphosphate. The plastic refractory for repairing the furnace lining of the intermediate frequency furnace is low in manufacturing cost, has excellent adhesive property, high temperature resistance and thermal shock resistance, further has the advantages of long service life, long storage time and the like, and solves the problems of poor adhesive property, short service life, short storage time and the like of the plastic refractory in the prior art.
本发明公开了一种中频炉炉衬修补用可塑料及其制备方法，属于中频炉用耐火材料技术领域。所述可塑料包括以下百分数的组分：矾土20%~30%，莫来石35%~45%，蓝晶石5%~15%，增塑剂5%~10%，葡萄糖3%~7%，氮化硅2%~5%，改性多聚磷酸铝10~15%；其中，所述改性多聚磷酸铝采用以下方法制备：将多聚磷酸铝、硅微粉、聚乙烯醇与水于180~220℃反应，冷却至室温得到改性多聚磷酸铝。本发明的中频炉炉衬修补用可塑料的制作成本低，且具备优异的粘结性能、耐高温性能、抗热震性能，此外，还具有使用寿命长以及可长时间存放等优点，解决了现有技术中可塑料的粘结性较差、使用寿命短、存放时间短等问题。
