Bio-based porous calcium silicate board and preparation process thereof
The invention discloses a bio-based porous calcium silicate board and a preparation process thereof. The calcium silicate board comprises the following raw materials in parts by weight: 20-30 parts of egg shells, 20-30 parts of diatomite, 5-10 parts of rice hull fibers and 1-10 parts of glutinous rice flour. The preparation process comprises the steps: grinding a certain proportion of egg shells into powder, uniformly mixing the powder with diatomite, calcining, uniformly mixing the calcined powder with a certain amount of rice hull fibers and glutinous rice flour, adding water to prepare slurry, and carrying out a series of processes such as mold pressing, demolding, steam curing and drying to prepare the green porous calcium silicate board. The used egg shells and rice hull material are rich in source, and waste resources can be recycled to the greatest extent; moreover, the egg shells and the diatomite have porous structures, so that the prepared porous calcium silicate board has the advantages of efficiently adsorbing harmful gas, regulating indoor humidity, preventing the board surface from mildewing and the like.
本发明公开了一种生物基多孔硅酸钙板及其制备工艺，所述硅酸钙板包括如下重量份的原料：20‑30份鸡蛋壳、20‑30份的硅藻土、5‑10份稻壳纤维、1‑10份的糯米粉；将一定比例的鸡蛋壳磨成粉与硅藻土混合均匀后煅烧，之后将煅烧得到的粉体与一定量的稻壳纤维、糯米粉混匀后加水制成浆料，经过压模、脱模、蒸养、干燥等系列工艺，制成一种绿色多孔的硅酸钙板。本发明使用的鸡蛋壳和稻壳材料来源丰富，能够最大程度的实现废弃资源再利用；而且，鸡蛋壳和硅藻土均具有多孔结构，制成的多孔硅酸钙板具有高效地吸附有害气体、调节室内湿度、防止板面发霉等优点。
