Ceramic vermiculite insulation board and preparation process thereof
The invention discloses a ceramic vermiculite insulation board and a preparation process thereof, and relates to the technical field of building materials. The invention discloses a ceramic vermiculite thermal insulation board, which is prepared from the following raw materials in percentage by mass: 55 to 65 percent of vermiculite mixture, 4 to 25 percent of spherical silica powder, 8 to 45 percent of siliceous clay, 3 to 6 percent of sodium bentonite, 1 to 4 percent of lepidolite powder, 0.5 to 3 percent of boric acid powder, 1 to 9 percent of calcium lignosulphonate and 0.01 to 0.05 percent of dispersing agent, the invention further discloses a preparation process of the ceramic vermiculite heat insulation plate. The ceramic vermiculite insulation board provided by the invention has the advantages of high normal-temperature and high-temperature strength, lower high-temperature heat conductivity coefficient, excellent chemical corrosion resistance, stable high-temperature volume and better comprehensive performance, can be used for an insulation layer of an aluminum electrolysis cell, and thoroughly solves the problems that the existing insulation layer of the aluminum electrolysis cell is compressed and corroded by electrolyte gas in a service cycle.
本发明公开一种陶瓷蛭石隔热板及其制备工艺，涉及建筑材料技术领域。本发明公开的陶瓷蛭石隔热板，是由以下质量百分比的原料组成：55～65％蛭石混料、4～25％球状硅微粉、8～45％硅质粘土、3～6％钠基膨润土、1～4％锂云母粉、0.5～3％硼酸粉末、1～9％木质素磺酸钙和0.01～0.05％的分散剂；本发明还公开了陶瓷蛭石隔热板的制备工艺。本发明提供的陶瓷蛭石隔热板，其常温和高温强度高，高温导热系数较低，抗化学腐蚀性能优异，高温体积稳定，综合性能较好，可用于铝电解槽保温层，彻底解决铝电解槽现有保温层在使用周期内被压缩、被电解质气体腐蚀等问题。
