Preparation method of environment-friendly anhydrous stemming
The invention provides a preparation method of environment-friendly anhydrous stemming, and belongs to the technical field of refractory materials. 28-35 parts of brown fused alumina, 35-40 parts of bauxite, 11-15 parts of clay, 5-8 parts of kyanite, 7-10 parts of ferro-silicon nitride, 14-20 parts of silicon carbide, 9-13 parts of sericite, 10-12 parts of an NS-FH composite sintering aid and 6-8 parts of mesoporous alumina are added into a stirrer to be stirred, and a first mixture is obtained; s2, 12-16 parts of a binding agent is added into the first mixed material obtained in the S1, stirring continues to be conducted, uniform mixing is conducted, and a second mixed material is obtained; the binding agent comprises glucose and glycerol, and the mass ratio of the glucose to the glycerol is (3-4): 1; and S3, extruding the second mixture obtained in the step S2 from a discharge port of the stirrer to obtain the environment-friendly anhydrous stemming. According to the present invention, the environmental protection is ensured, the apparent porosity is reduced, and the compression strength of the prepared anhydrous stemming is improved.
本发明提供了一种环保无水炮泥的制备方法，属于耐火材料技术领域，包括如下步骤：S1、按重量份数计，将棕刚玉28‑35份、铝矾土35‑40份、粘土11‑15份、蓝晶石5‑8份、氮化硅铁7‑10份、碳化硅14‑20份、绢云母9‑13份、NS‑FH复合烧结助剂10‑12份和介孔氧化铝6‑8份加入搅拌机中，进行搅拌，得到第一混合料；S2、向S1所得第一混合料中添加结合剂12‑16份，继续进行搅拌，混匀，得到第二混合料；结合剂包括葡萄糖和甘油，且二者的质量比为（3‑4）：1；S3、将S2所得第二混合料从搅拌机的出料口挤出，即得环保无水炮泥。本发明确保更加环保的同时，降低显气孔率，提高制得无水炮泥的耐压强度。
