Preparation method of environment-friendly autoclaved coal gangue brick
The invention discloses a preparation method of an environment-friendly autoclaved coal gangue brick. The preparation method comprises the following steps that 1, raw materials are weighed and comprise 40-60 parts of coal gangue powder, 18-20 parts of fly ash, 20-30 parts of a thermal insulation component, 8-10 parts of kaolin, 3.3-5.5 parts of sodium aluminate, 2.3-4.5 parts of sodium sulfate, 1.2-1.6 parts of an air entraining agent and 5-7 parts of water; 2, mixing is conducted to obtain a brick blank; and 3, autoclaved curing is conducted, wherein the thermal insulation component is obtained by compounding silicon dioxide aerogel and a modified component, the modified component is expanded perlite modified by a modifier, the modifier is combined with the expanded perlite through a fatty acid chain, so that the thermal insulation component has good hydrophobic performance and flame retardant performance, and the finally prepared thermal insulation component enables the prepared coal gangue brick to have a good thermal insulation effect.
本发明公开了一种环保型蒸压煤矸石砖的制备方法,包括如下步骤:步骤一:称取原料:煤矸石粉料40‑60份、粉煤灰18‑20份、保温组分20‑30份、高岭土8‑10份、铝酸钠3.3‑5.5份、硫酸钠2.3‑4.5份、引气剂1.2‑1.6份、水5‑7份;步骤二:混合、制得砖胚;步骤三:蒸压养护,其中保温组分由二氧化硅气凝胶和改性组分复配得到,改性组分为使用改性剂改性的膨胀珍珠岩,改性剂通过脂肪酸链与膨胀珍珠岩结合,使其带有良好的疏水性能和阻燃性能,最终制得的保温组分使制得煤矸石砖具有良好的保温效果。
