Micro-expansion high-temperature-resistant heat insulation plate and preparation method thereof
The invention discloses a micro-expansion high-temperature-resistant thermal insulation board and a preparation method thereof, and the micro-expansion high-temperature-resistant thermal insulation board comprises the following raw materials in percentage by mass: 30%-75% of low-temperature expanded vermiculite, 5%-30% of kyanite and/or andalusite, 5%-20% of premixed powder and 15%-40% of a binding agent, the low-temperature expanded vermiculite is incomplete expanded vermiculite and is obtained by expanding raw ore vermiculite at 400-600 DEG C for 1-2 minutes; the premixed powder is prepared from the following raw materials in percentage by mass: 1-5% of explosion-proof fiber micro powder, 1-3% of a dispersing agent, 1-10% of caustic-burned magnesia micro powder, 1-5% of silicon micro powder and 1-5% of an additive, wherein the total mass of the raw materials is 100%; the additive is at least one of sodium tripolyphosphate, aluminum hexametaphosphate, sodium fluosilicate and potassium fluosilicate; the binding agent is a modified sodium silicate and/or potassium silicate solution added with aluminum oxide and/or zirconium oxide fibers. The preparation method comprises the following steps: uniformly mixing the raw materials, carrying out compression molding, and drying at 120-300 DEG C for 2-4 hours to obtain the micro-expansion high-temperature-resistant heat insulation
本发明公开了一种微膨胀耐高温绝热板及其制备方法，以质量百分比计，原料组成包括：低温膨胀蛭石30％～75％，蓝晶石和/或红柱石5％～30％，预混合粉5％～20％，结合剂15％～40％；低温膨胀蛭石为不完全膨胀蛭石，由原矿蛭石于400～600℃膨胀1～2分钟获得；以原料的总质量为100％计，预混合粉的组成包括：防爆纤维微粉1％～5％，分散剂1％～3％，轻烧镁微粉1％～10％，硅微粉1％～5％，外加剂1％～5％；外加剂为三聚磷酸钠、六偏磷酸铝、氟硅酸钠、氟硅酸钾中的至少一种；结合剂为添加了氧化铝和/或氧化锆纤维的改性硅酸钠和/或硅酸钾溶液。制备方法：将原料混匀后模压成型，120～300℃干燥2～4h得微膨胀耐高温绝热板。
