The invention provides a production process of an anti-seismic autoclaved aerated concrete block, and relates to the field of concrete blocks. The production process comprises the following steps: preparing a modifier; modifying silicone oil with the modifier; adding a mixed powder and glass fibers into a ball mill, adding a certain amount of modified silicone oil in the ball milling process, carrying out ball milling for 3-8 h, mixing the obtained material with an additive, and adding water with the temperature of 55 DEG C, stirring for 1-5 min at the rotating speed of 600-800 r/min in a 55 DEG C water bath, then adding a certain amount of aluminum powder, continuously stirring for 5-10 min, injecting the obtained slurry into a mold preheated to 55 DEG C, carrying out gas foaming for 20-30 min, and taking out a blank block obtained after gas foaming from the mold; pre-curing in an oven at 50-60 DEG C, cutting, feeding the cut blank block into an autoclave, increasing the pressure to 1-1.5 MPa within 2-4 h, carrying out constant-temperature and constant-pressure treatment for 6-8 h, and lowering the temperature and the pressure to normal temperature and normal pressure to obtain the finished product. The anti-seismic autoclaved aerated concrete block is excellent in various properties, accords with and is far superior to the national standard, and has a great application prospect.
本发明提供一种抗震蒸压加气混凝土砌块的生产工艺，涉及混凝土砌块领域，包括以下步骤：制备改性剂；利用改性剂对硅油进行改性；将混合粉料、玻璃纤维加入到球磨机中，进行球磨的过程中添加一定量的改性硅油，球磨3‑8h后将物料与外加剂混合并加入温度为55℃的水，55℃水浴下以600‑800r/min的转速搅拌1‑5min后再加入一定量的铝粉，继续搅拌5‑10min后将浆料注入到预热至55℃的模具中发气20‑30min，将发气后得到的胚块从模具中取出；50‑60℃烘箱预养，切割，切割后的胚块送至蒸压釜内，在2‑4h内增压至1‑1.5MPa，恒温恒压6‑8h后，再降温降压至常温常压，即可得到成品，本发明抗震蒸压加气混凝土砌块各项性能优异，符合且远远优于国家标准，具有极大的应用前景。
