High-strength rock plate and preparation method thereof
The invention discloses a high-strength rock plate and a preparation method thereof, and belongs to the technical field of rock plates. The high-strength rock plate is prepared from the following raw materials in parts by weight: 22 to 30 parts of albite, 15 to 20 parts of kaolin, 10 to 16 parts of nepheline powder, 6 to 12 parts of wollastonite, 5 to 9 parts of clay, 4 to 8 parts of hydroxyapatite, 3 to 6 parts of modified hollow glass beads, 2 to 6 parts of modified silicon carbide whiskers, 2 to 6 parts of aluminum oxide, 1 to 3 parts of strontium carbonate, 0.8 to 2 parts of calcium hydrophosphate, 0.8 to 2 parts of aluminum hydroxide, 1 to 2 parts of corundum powder, 0.6 to 1.5 parts of zinc oxide and 0.5 to 1 part of lanthanum carbonate. The rock plate disclosed by the invention has good breaking strength, and the modified silicon carbide whisker capable of remarkably improving the breaking strength is obtained by synthesizing and sintering in a solution by taking silicon dioxide and fly ash as silicon sources and crushed lignite as a carbon source.
本发明公开了一种高强度岩板及其制备方法，属于岩板技术领域，所述高强度岩板由以下重量份原料制备而成：22~30份钠长石、15~20份高岭土、10~16份霞石粉、6~12份硅灰石、5~9份粘土、4~8份羟基磷灰石、3~6份改性空心玻璃微珠、2~6份改性碳化硅晶须、2~6份氧化铝、1~3份碳酸锶、0.8~2份磷酸氢钙、0.8~2份氢氧化铝、1~2份刚玉粉、0.6~1.5份氧化锌、0.5~1份碳酸镧。本发明所述的岩板具有良好的抗折强度，通过以二氧化硅、粉煤灰为硅源，以粉碎后的褐煤为碳源，在溶液下合成，烧结，得到了能够显著提高抗折强度的改性碳化硅晶须。
