Hard inorganic eco-stone and preparation process thereof
The invention provides a hard inorganic ecological stone and a preparation process thereof, the hard inorganic ecological stone comprises the following raw materials by weight: 22-58 parts of cement, 23-48 parts of a modified inorganic filler, 5-8 parts of a green body flexibilizer, 3-5 parts of anti-crack powder, 2-4 parts of a water reducer, and 12-20 parts of water, the modified inorganic filler is prepared by modifying an inorganic filler, the green body toughening agent is prepared from silicon carbide chopped fibers, nano zirconium oxide and glass beads with the mass ratio of (15-22): (6-10): (2-5), the anti-cracking powder is acidified pseudo-boehmite, the pseudo-boehmite and an acid solution are uniformly mixed at the temperature of 60-80 DEG C according to the mass-volume ratio g/mL of (2.5-3.5): 5, the strength is effectively improved after the inorganic filler is modified, the raw materials are prepared and scientifically proportioned, the components are uniform, and the anti-cracking performance is good. The performance of the inorganic ecological stone is synergistically enhanced, the Moh's hardness is obviously improved, the compressive strength, the falling ball impact strength and the density are improved, the water absorption rate of the inorganic ecological stone is reduced, and the comprehensive performance of the inorganic ecological stone is improved.
本发明提供一种硬质无机生态石及其制备工艺，包括以下重量份原料：水泥22‑58份、改性无机填料23‑48份、坯体增韧剂5‑8份、抗裂粉3‑5份、减水剂2‑4份、水12‑20份，所述改性无机填料是将无机填料经改性后制得，所述坯体增韧剂为质量为(15‑22):(6‑10):(2‑5)的碳化硅短切纤维、纳米氧化锆、玻化微珠，所述抗裂粉为酸化拟薄水铝石，取拟薄水铝石与酸溶液在60‑80℃下按照质量体积比g/mL为(2.5‑3.5):5混合均匀，无机填料经改性后强度有效提高，经各原料配制，科学配比、成分均匀，协同增强其性能作用，莫氏硬度明显提高，提高了抗压强度、落球冲击强度和密度，降低无机生态石的吸水率，提高无机生态石的综合性能。
