Preparation method of building external thermal insulation prefabricated wallboard
The invention provides a preparation method of a building external thermal insulation prefabricated wallboard, which comprises the following steps: preparing a thermal insulation layer material: uniformly mixing cement and an accelerator to obtain mixed powder, soaking modified polystyrene foam balls in water for 2-3 minutes, adding the soaked modified polystyrene foam balls into the mixed powder, and stirring to form a layer of cement shell on the surface of the modified polystyrene foam balls, so as to obtain the thermal insulation layer material; then adding water for mixing and stirring; an inner-layer plate and an outer-layer plate are prepared respectively, a heat preservation layer material is poured between the inner-layer plate and the outer-layer plate, maintenance is carried out, and the building external heat preservation prefabricated wallboard is obtained. According to the invention, the contact surface and the friction force between the foam balls and the cement-based material are increased, meanwhile, the interface cohesiveness between the foam balls and the cement-based material is improved, the uniform dispersion of the foam balls is ensured, and the thermal insulation effect and the mechanical property of the thermal insulation layer are improved.
本发明提出了一种建筑外保温预制墙板的制备方法，所述制备方法包括以下步骤：制备保温层材料：将水泥和速凝剂混合均匀得到混合粉，将改性聚苯乙烯泡沫球水浸2‑3min，加入到混合粉中搅拌，使改性聚苯乙烯泡沫球表面形成一层水泥壳，然后加入水进行混合搅拌；分别制备内层板和外层板，向内层板和外层板之间浇筑保温层材料，进行养护，获得建筑外保温预制墙板。本发明增大了泡沫球与水泥基材料之间的接触面和摩擦力，同时提高了泡沫球与水泥基材料之间界面粘结性，保证泡沫球的均匀分散，提高保温层的保温效果和力学性能。
