High-water-resistance carbonized consolidated fiber cement board and preparation method thereof
The invention provides a high-water-resistance carbonized and consolidated fiber cement board and a preparation method thereof, and belongs to the field of building materials. Mixing fibers, a gelling component and water to obtain slurry; the fibers are glass fibers and wood fibers or polyvinyl alcohol fibers and wood fibers; the gelling component comprises one or more of calcium silicate mineral powder, steel slag powder rich in calcium silicate mineral phase and magnesium slag powder rich in calcium silicate mineral phase; the slurry is sequentially subjected to dehydration, mud jacking and static curing, curing is conducted in the CO2 atmosphere, and the high-water-resistance carbonization consolidation fiber cement board is obtained. The glass fibers are doped to replace plant wood fibers, and hydrophobic groups on the surfaces of the glass fibers can effectively reduce the water absorption rate of the fiber cement board; the gelling component used in the invention has excellent CO2 reaction activity, can be subjected to mineralization reaction with CO2 to form a matrix structure composed of calcium carbonate, and is a main strength source of the fiber cement board.
本发明提供了一种高耐水碳化固结纤维水泥板及其制备方法，属于建筑材料领域。将纤维、胶凝组分和水混合，得到浆料；所述纤维为玻璃纤维和木质纤维或者聚乙烯醇纤维和木质纤维；所述胶凝组分包括硅酸钙矿粉、富含硅酸钙矿相的钢渣粉和富含硅酸钙矿相的镁渣粉中的一种或多种；将所述浆料依次进行脱水、压浆和静养、在CO2氛围下养护，得到所述高耐水碳化固结纤维水泥板。本发明通过掺加玻璃纤维来替代植物木质纤维，玻璃纤维表面的疏水基团可有效降低纤维水泥板的吸水率；本发明所用胶凝组分具有优异的CO2反应活性，能够与CO2发生矿化反应，形成以碳酸钙为组成的基体结构，是纤维水泥板的主要强度来源。
