High-strength amorphous refractory material and preparation method thereof
The invention relates to the technical field of refractory materials, and particularly discloses a high-strength amorphous refractory material and a preparation method thereof. A preparation method of a high-strength amorphous refractory material comprises the following steps: S1, uniformly mixing high-alumina bauxite, silica fume, quartz sand, aluminum oxide, zirconium oxide and silicon carbide in a stirring kettle, and drying to obtain a base material; s2, adding sodium alginate, nano silicon dioxide, sodium borate and deionized water into a reaction kettle, and uniformly mixing to obtain an intermediate solution; s3, alkyl amide, polyvinyl alcohol and aluminum chloride continue to be added into the intermediate liquid, stirring continues to be conducted for 1.5 h, and then dehydration is conducted till the mixture is sticky to prepare the low-temperature binding agent; s4, adding magnesium oxide, emery powder, tetrabutyl phosphorus hydroxide and deionized water into the stirring kettle, and stirring to obtain a high-temperature binding agent; and S5, preparing the base material, the low-temperature binding agent and the high-temperature binding agent. The high-strength amorphous refractory material prepared in the invention has the advantage of good mechanical properties in high and low temperature environments.
本申请涉及耐火材料技术领域，具体公开了一种高强度不定型耐火材料及其制备方法。一种高强度不定型耐火材料的制备方法，包括如下步骤：S1：取高铝矾土、微硅粉、石英砂、氧化铝、氧化锆、碳化硅在搅拌釜内混合均匀，干燥后得到基料；S2：向反应釜内加入海藻酸钠、纳米二氧化硅、硼酸钠、去离子水混合均匀制得中间液；S3：继续向中间液内加入烷基酰胺、聚乙烯醇、氯化铝，继续搅拌1.5h，然后脱水至黏稠状后制得低温结合剂；S4：向搅拌釜内加入氧化镁、刚玉粉、四丁基氢氧化磷、去离子水，搅拌制得高温结合剂；S5：取基料、低温结合剂、高温结合剂配制即得。本申请制得的高强度不定型耐火材料在高低温环境下具有力学性能好的优点。
