Preparation method of high-temperature calcined heat insulation hollow glass colored sand
The invention relates to a preparation method of high-temperature calcined heat insulation hollow glass colored sand, and belongs to the technical field of non-metallic material preparation. The method comprises the following steps: mixing fluorite tailings, dolomite and other substances, grinding, sieving, mixing with deionized water, dispersing to obtain a suspension, mixing with sodium methoxide, tetraethyl silicate and other substances, heating, reacting, performing centrifugal separation, soaking and filtering the centrifugate in a sodium hydroxide solution, and washing, drying and calcining the filtered substance to obtain the fluorite tailings-dolomite composite material. And oxidizing with hydrogen peroxide, modifying with a coupling agent, filtering, washing, drying, and carrying out ball milling to obtain the heat-insulating and heat-preserving hollow glass color sand. The mechanical property of the prepared heat insulation hollow colored sand is remarkably improved, and the thermal stability is improved by 13-15%; and the hydrophobic property is improved, and the coating is not easy to harden due to moisture absorption when exposed in air and has flowability.
本发明涉及一种高温煅烧隔热保温空心玻璃彩砂制备方法，属于非金属材料制备技术领域。本发明首先将一种将萤石尾矿、白云石等物质混合，碾磨过筛，并与去离子水混合分散，得悬浮液，并将其与甲醇钠、硅酸四乙酯等物质混合加热反应，再离心分离，将离心物置于氢氧化钠溶液浸泡，过滤，将过滤物洗涤，干燥，煅烧，得到隔热保温空心玻璃彩砂，接着分别用双氧水氧化和偶联剂改性，过滤，洗涤，干燥，球磨即可得到隔热保温空心玻璃彩砂。本发明制备的隔热保温空心彩砂力学性能得到显著提高，热稳定性能提高13～15％；且憎水性能提高，暴露在空气中不易吸潮而板结，流动性。
