Composite binding agent for aluminum-silicon refractory material and preparation method of composite binding agent
The invention discloses a composite binding agent for an aluminum-silicon refractory material and a preparation method of the composite binding agent, and relates to the technical field of refractory material production. The composite binding agent is prepared from the following raw materials: aluminum hydroxide, aluminum sulfate, aluminum citrate, aluminum-silicon mixed sol and polyvinyl alcohol, wherein the aluminum-silicon mixed sol is prepared by mixing 70% by mass of aluminum sol and 30% by mass of silica sol. The preparation method of the organic-inorganic composite binding agent is simple in process and wide in application range, and the raw materials are rich in source, low in price and small in dosage; when the binding agent prepared by the method is used in the aluminum-silicon refractory material, the binding capacity at medium, low and high temperatures is increased, and the binding agent is non-toxic, odorless and environment-friendly; the product strength is effectively improved, the thermal shock resistance is good, the erosion resistance is high, the service life of the refractory material is prolonged, and the economic benefits of cement enterprises are increased.
本发明公开了一种铝硅质耐火材料用复合结合剂及其制备方法，涉及耐火材料生产技术领域。复合结合剂由以下原料制成：氢氧化铝、硫酸铝、柠檬酸铝、铝硅混合溶胶和聚乙烯醇，其中铝硅混合溶胶按质量百分比将70%的铝溶胶与30%的硅溶胶混合而成。本发明提供了一种工艺简单、适用范围广的有机‑无机复合结合剂的制备方法，原料来源丰富、价格低廉，用量少；用该方法所制备的结合剂用于铝硅质耐火材料中不仅增加了中低高温度下的结合能力，且无毒无味环境友好；有效提高了制品强度、抗热震性能好、抗侵蚀性能强，延长了耐火材料的使用寿命，增加了水泥企业的经济效益。
