Description

含有耐火空心球的隔热耐火浇注料
技术领域
本发明属于耐火材料技术领域，尤其涉及一种含有耐火空心球的隔热耐火浇注料。
背景技术
轻质隔热耐火浇注料是指低导热系数和低热容量的耐火浇注料，也称保温耐火浇注料。隔热耐火浇注料主要是通过引入气孔的方式来获得低热导率，一般来讲材料的气孔率越高其热导率越低，气孔的孔径越小材料的热导率也越低隔热效果越好。隔热耐火材料在降低高温设备的能源消耗、满足高温特殊工艺要求上有着广泛的用途。
发明内容
本发明提供一种抗震性能好的含有耐火空心球的隔热耐火浇注料。
一种含有耐火空心球的隔热耐火浇注料， 由以下原料组成：烧结刚玉、氧化锆纤维、氧化铝空心球、氧化锆铝空心球、氧化铝微粉、氧化钇、二氧化硅微粉，其中，烧结刚玉、氧化铝空心球、氧化锆铝空心球为骨料，氧化铝微粉、二氧化硅微粉、氧化钇、为基质；上述原料的重量份数为：烧结刚玉15~20份、氧化锆纤维10~20份、氧化锆铝空心球5~10份、氧化铝空心球20~25份、氧化铝微粉20~25份、二氧化硅微粉5~10份、氧化钇5~10份。
综上所述，本发明与现有技术相比，骨料中的氧化铝空心球、氧化锆铝空心球具有特殊的表面结构且内部空心，表面凹凸不平，增大接触比表面积，使得骨料与基质中氧化铝微粉、二氧化硅微粉结合牢固，既提高了耐火性能，又增加了物料的强度以及保温效果，以及利用氧化钇来保持氧化锆纤维、氧化锆铝空心球的稳定性，进而提高含有耐火空心球的隔热耐火浇注料的耐散列性和耐腐蚀性。
具体实施方式
下面结合实施例对本发明作进一步详细说明。本具体实施例仅仅是对本发明的解释，其并不是对发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出任何修改，但只要在本发明的权利要求范围内都受到专利法的保护。
