The invention relates to the technical field of aerated bricks, particularly to a preparation method of a high-strength aerated brick. The preparation method comprises the following steps: a, mixing and stirring raw materials according to a certain ratio to obtain a slurry; b, adding aerated aluminum powder, stirring for 1 minute, and pouring a mold frame; c, carrying out gas generation and initial setting; d, cutting the green body; e, carrying out autoclaved curing for 3 hours; f, spraying the cement slurry on the inner side and the outer side of the brick, and continuously performing autoclaved curing for 2 hours; and g, naturally curing. According to the invention, the autoclaved curing of the aerated brick is divided into two stages, wherein autoclaved curing is firstly carried out for 3 hours, then cement slurry is sprayed, then autoclaving is continuously carried out for 2 hours, and the cement slurry can permeate a certain thickness from outside to inside and forms a bonding layer with the aerated brick, so that the surface performance of the aerated brick is improved, and the bonding layer is high in hardness, not prone to dusting and capable of being easily bonded with mortar.
本发明涉及加气砖技术领域，尤其涉及一种高强度加气砖的制备方法，包括：a、将原料按照一定配比混合搅拌，得到料浆；b、投入加气铝粉并搅拌1分钟，浇注模框；c、发气初凝；d、切割坯体；e、蒸压养护3小时；f、将水泥浆喷淋在砖块的内侧和外侧，继续蒸压养护2小时；g、自然养护，本发明的加气砖的蒸压养护分为两个阶段，先蒸压养护3小时，然后喷淋水泥浆，然后再继续蒸压2小时，水泥浆会从外向内渗透一定厚度，并与加气砖形成结合层，改善了加气砖的表面性能，该结合层处硬度较高，不易起粉末，而且使得其易于与砂浆粘结。
