Production and preparation method of prefabricated external wall panel
The invention discloses a production and preparation method of a prefabricated external wall panel, and relates to the technical field of prefabricated external wall panels. The method comprises the following steps: S01, manufacturing a mold and carrying out pretreatment; s02, assembling a mold; s03, preparing concrete; s04, maintenance is conducted; and S05, demolding is conducted, specifically, the cured concrete external wall panel is subjected to demolding, surface finishing is conducted according to the needed size, and preparation is completed. According to the prefabricated external wall panel manufactured through the method, foaming liquid mixed with a foaming agent is prepared into stable foam, then the stable foam is added into cement mortar prepared from cement, sand, water, additives and the like, and after even mixing, pouring and curing are conducted to form a porous material, and compared with ordinary mortar, a large number of closed air holes exist in the material; and the mechanical properties, especially the brittleness and bending strength, of the cement-based material can be improved by doping the fibers, so that the compressive strength and the brittleness characteristic of the cement-based material can be improved.
本发明公开了一种预制外墙板生产制备方法，涉及预制外墙板技术领域。本发明包括如下步骤：S01、制作模具并进行预先处理；S02、组模；S03、混凝土配置；S04、养护；S05、脱模：对养护好的混凝土外墙板进行脱模，并对所需要的尺寸进行收面，完成制备。本发明制作的预制外墙板掺有泡沫剂的发泡液制备成稳定泡沫，再将其加入到由水泥、砂、水和外加剂等制成的水泥砂浆中，混合均匀后浇注养护形成的多孔材料，和普通砂浆相比，其材料内部存在大量封闭气孔，因而具有轻质、防火、保温等优点，通过掺加纤维可改善水泥基材料的力学性能，尤其是脆性和抗弯强度，从而可提高了其抗压强度以及脆性特征。
