Erosion-resistant light-weight fire-resistant spray coating and preparation method thereof
The invention belongs to the technical field of refractory materials, and discloses an erosion-resistant light-weight refractory spray coating and a preparation method thereof. The preparation method comprises the following steps: step 1, mixing and stirring calcium hexaluminate particles, magnesium aluminate spinel fine powder, alumina fibers, calcium lignosulphonate and calcium aluminate cement to obtain a premix; step 2, adding borax into the premix, and stirring to obtain a mixture; 3, adding water into the mixture, and stirring to obtain a precursor material; 4, sodium oxalate is added into the precursor material for stirring, then water is added for stirring, and the erosion-resistant light-weight fireproof spray coating is obtained. The preparation process is simple, and the prepared spray coating is easy to construct, quick to sinter, high in early strength and good in bonding performance, has the characteristics of low heat conductivity coefficient and corrosion resistance, and is widely applicable to lining materials of high-temperature industrial kilns in alkaline working environments.
本发明属于耐火材料技术领域，公开了一种耐侵蚀轻量耐火喷涂料及其制备方法。其制备方法包括以下步骤：步骤1，将六铝酸钙颗粒、镁铝尖晶石细粉、氧化铝纤维、木质素磺酸钙和铝酸钙水泥混合搅拌，得到预混料；步骤2，向预混料中加入硼砂搅拌，得到混合料；步骤3，向混合料中加入水搅拌，得到前驱体料；步骤4，向前驱体料中加入草酸钠搅拌，再加入水搅拌，得到耐侵蚀轻量耐火喷涂料。本发明制备工艺简单，制备的喷涂料易施工、烧结快、早期强度高，结合性能好，且兼具导热系数低和耐侵蚀的特点，广泛适用于碱性工作环境下高温工业窑炉的内衬材料。
