Medium-density diatomite fiber cement board and preparation method thereof
The invention provides a medium-density diatomite fiber cement board. The cement board comprises the following components in parts by weight: 22-30 parts of diatomite, 20-30 parts of quartz sand, 35-48 parts of cement, 0-10 parts of fly ash, 2-8 parts of silica fume, 1-5 parts of lignocellulose and 0.5-1 part of hydroxypropyl methyl cellulose. In addition, the invention also provides a preparationmethod of the medium-density diatomite fiber cement board. Quartz stone is partially replaced with diatomite, and the stacking density and hardness of the diatomite are far lower than those of quartzsand. Compared with a high-density fiber cement board prepared from pure quartz sand, the board prepared from diatomite is lighter in dead weight, few in accessories and keels required by board building construction, low in cost and high in construction efficiency, and the product competitiveness of the board is improved; and meanwhile, a vacuum extrusion process is adopted for production, compared with a traditional slurry flowing method and a traditional papermaking method, the water consumption is lower, and the produced board has the excellent characteristics of being low in porosity, high in breaking strength, good in durability and the like.
本发明提供了一种中密度硅藻土纤维水泥板，包括按重量份数计的如下组分：硅藻土22～30份，石英砂20～30份，水泥35～48份，粉煤灰0～10份，微硅粉2～8份，木质纤维素1～5份，羟丙基甲基纤维素0.5～1份。另外，本发明还提供了该中密度硅藻土纤维水泥板的制备方法。该发明采用硅藻土部分替代石英石使用，硅藻土的堆积密度及硬度远远低于石英砂，与纯石英砂为原料制备的高密度纤维水泥板相比，采用硅藻土制备的板材自重更轻，板材建筑施工所需配件、龙骨少，成本低，施工效率高，提高了板材的产品竞争力；同时采用真空挤出工艺生产，比传统的流浆法、抄取法用水量更少，生产的板材具有孔隙率低、抗折强度高、耐久性好等优良特性。
