Aluminum-silicon castable added with floating beads and preparation method of aluminum-silicon castable
The invention discloses an aluminum-silicon castable added with floating beads and a preparation method of the aluminum-silicon castable. The aluminum-silicon castable is prepared from the following raw materials in percentage by weight: 30%-46% of calcium aluminate cement, 1%-6% of silica powder, 40%-45% of perlite aggregate, 3%-8% of sinking beads and 0%-16% of floating beads. According to the aluminum-silicon castable added with the floating beads and the preparation method of the aluminum-silicon castable, the light perlite is used as the aggregate, fine particles such as the silica powder and the sinking beads are added, the heat conductivity coefficient can be remarkably improved by adding a proper amount of the floating beads, the volume weight of the floating beads is small, and the fluidity of the castable raw materials is better improved due to the fact that the floating beads are spherical; and the floating beads are large in specific surface area and high in reaction activity in the castable, are favorable for improving the combination among the raw materials, improving the strength and the volume density of the floating beads, and can form a uniform gas-phase connection structure with the lightweight porous perlite, so that the heat conductivity is reduced, and the heat preservation effect is improved.
本发明公开了一种添加漂珠的铝硅系浇注料及其制备方法，包括以下份额的原材料：所述铝酸钙水泥的份额为30％～46％，所述硅微粉的份额为1％～6％，所述珍珠岩骨料的份额为40％～45％，所述沉珠的份额为3％～8％，所述漂珠的份额为0％～16％。本发明所述的一种添加漂珠的铝硅系浇注料及其制备方法，以轻质珍珠岩为骨料，加入硅微粉，沉珠等细颗粒，加入适量的漂珠可以显著改善导热系数，且漂珠容重小，球形更有利于浇注料原料之间的流动性的增加，漂珠自身在浇注料中比表面积大，反应活性高，有利于改善原料间的结合，提高强度，自身体积密度，可与轻质多孔珍珠岩形成均匀的气相连接结构，故降低热导率，保温效果提高。
