Anti-cracking refractory castable for kiln and preparation method of anti-cracking refractory castable
The invention belongs to the field of refractory materials, and particularly relates to an anti-cracking refractory castable for a kiln and a preparation method of the anti-cracking refractory castable. The anti-cracking refractory castable for the kiln is prepared from the following raw materials in parts by weight: 30 to 50 parts of aluminum oxide ceramic whiskers, 5 to 10 parts of silicon carbide whiskers, 3 to 5 parts of aluminum carbide whiskers, 8 to 18 parts of silicon oxide whiskers, 4 to 6 parts of basalt fibers, 0.2 to 0.4 part of sodium tripolyphosphate, 1 to 2 parts of polydimethylsiloxane, 3 to 8 parts of aluminum silicate cement and 20 to 40 parts of deionized water. According to the anti-cracking refractory castable for the kiln, the refractory materials with different average diameters are adopted as main materials, the compression strength of the anti-cracking refractory castable for the kiln can be improved while the compactness is enhanced, the toughness of the castable is enhanced by adding the basalt fibers, and the shock resistance and the explosion-proof performance are improved.
本发明属于耐火材料领域，尤其涉及一种窑炉用防开裂耐火浇注料及其制备方法。本发明的窑炉用防开裂耐火浇注料按重量份数计，包括以下原料：30‑50份氧化铝陶瓷晶须、5‑10份碳化硅晶须、3‑5份碳化铝晶须、8‑18份氧化硅晶须、4‑6份玄武岩纤维、0.2‑0.4份三聚磷酸钠、1‑2份聚二甲基硅氧烷、3‑8份硅酸铝水泥、20‑40份去离子水；本发明通过采用不同平均直径的耐火材料作为主料，在增强致密性能的同时能提高窑炉用防开裂耐火浇注料的耐压强度，并且通过加入玄武岩纤维增强浇注料的韧性，提高抗震性以及防爆性能。
