The invention provides an inorganic artificial stone and a preparation process thereof. The inorganic artificial stone is prepared from the following raw materials in parts by weight: 22.5-23.5% of white cement; 3%-4% of superfine calcium powder; 1.2%-2% of metakaolin; 1.2%-2% of silica fume; 2.8%-3.5% of calcium powder; 66.8% to 67.5% of aggregate; the emulsion accounts for 1.5%-3% of the total weight of the powder, the water accounts for 3%-5% of the total weight of the powder, the water reducing agent accounts for 3%-5% of the total weight of the powder, and the nucleating agent accounts for 2.5%-3.5% of the total weight of the powder. The production process is stable, the product quality is uniform, and no color difference exists; the cracking probability of the square stock is small, the cracking risk is reduced through hydration heat control of the square stock and production and maintenance temperature control, and the cracking risk can be detected in time; the product performance is high, the bending strength is greater than or equal to 15MPa, the water absorption is less than or equal to 0.3%, the compressive strength is greater than or equal to 80MPa, and the density is greater than or equal to 2.45 The mold removal time is early, and the mold turnover speed is high.
本发明提供了无机型人造石及其制备工艺，其制备包括下述重量份的原料：白水泥22.5%‑23.5%；超细钙粉3%‑4%；偏高岭土1.2%‑2%；硅灰1.2%‑2%；钙粉2.8%‑3.5%；骨料66.8%‑67.5%；还包括掺量为1.5%‑3%粉料总重的乳液，3%‑5%粉料总重的水，3%‑5%粉料总重的减水剂，2.5‰‑3.5‰粉料总重的晶核剂。本发明生产工艺稳定，产品品质均匀，无色差；方料开裂几率小，通过方料水化热控制和生产、养护温度控制降低开裂风险，并且如果有开裂风险可以及时检测到；产品性能高，抗弯强度≥15MPa，吸水率≤0.3%，抗压强度≥80MPa，密度≥2.45kg/m³；拆模时间早，模具周转速度快。
