Light fiber cement board and preparation method thereof
The invention discloses a light fiber cement board and a preparation method thereof, and belongs to the technical field of building materials. The light fiber cement board comprises the following raw materials in parts by weight: 30-40 parts of cement, 10-20 parts of floating beads, 10-15 parts of quartz sand tailings, 8-10 parts of wood pulp, 8-10 parts of aluminum oxide, 5-10 parts of calcium sulfate whiskers, 5-10 parts of perlite, 5-10 parts of mica sheets and 1-5 parts of kaolin; the volume weight of the floating beads is less than 420 kg/m < 3 >. The raw materials of the light fiber cement board do not contain pre-reaction materials, the problem of sewage treatment in the production process is solved, and meanwhile, the light fiber cement board has the advantages of low density and high strength, and is good in fireproof heat insulation effect, good in humidity adjusting performance and high in market competitiveness. The density of the light fiber cement board can reach 0.7-0.8 g/cm < 3 >, the breaking strength is greater than or equal to 12MPa, the impact strength is greater than or equal to 3KJ/m < 2 >, the heat conductivity coefficient is less than or equal to 0.10 W/(m.K), the fire endurance is greater than or equal to 4h, the indoor 24h moisture absorption is greater than or equal to 80 * 10 <-3 > kg/m < 2 >, and the indoor 24h moisture liberation is greater than or equal to 70 * 10 <-3 > kg/m < 2 >.
本发明公开了一种轻质纤维水泥板及其制备方法，属于建筑材料技术领域。所述轻质纤维水泥板包括以下重量份数的各原料：水泥30～40份，漂珠10～20份，石英砂尾矿10～15份，木浆8～10份，氧化铝8～10份，硫酸钙晶须5～10份，珍珠岩5～10份，云母片5～10份，高岭土1～5份；所述漂珠的容重小于420kg/m3。本发明的轻质纤维水泥板的原料中不含有预反应料，解决了生产过程中污水处理的问题，同时轻质纤维水泥板兼具低密度和高强度的优点，防火隔热效果好，调湿性能好，市场竞争力强。所述轻质纤维水泥板的密度可达到0.7～0.8g/cm3，抗折强度≥12MPa，抗冲击强度≥3KJ/m2，导热系数≤0.10W/(m·K)，耐火极限≥4h，室内24h吸湿量≥80*10‑3kg/m2，室内24h放湿量≥70*10‑3kg/m2。
