Preparation method of regenerated insulation material suitable for masonry

XIA LIPING / SHEN JIAHAO

The invention discloses a preparation method of a regenerated insulation material suitable for masonry. The regenerated insulation material comprises coarse aggregate, fine aggregate, sandstone, portland cement and a foaming agent, wherein the coarse aggregate is particles which are formed by crushing waste polystyrene foam boards and have the diameter greater than 5mm, the fine aggregate is particles which are screened by grinding waste concrete blocks and have the diameter smaller than 5 mm, the portland cement, the fine aggregate and the sandstone are mixed with water according to the proportion of 7:2:1 so as to prepare an outer wear-resistant material, and the portland cement, the coarse aggregate and the fine aggregate are mixed with water according to the proportion of 7:1:2 so as to prepare a light insulation material through foaming of the foaming agent. According to the preparation method of the regenerated insulation material suitable for the masonry, waste concrete is used as the fine aggregate so as to prepare the outer wear-resistant material and the light insulation material, and waste polystyrene foam particles are used as the coarse aggregate so as to prepare the light insulation material, so that the waste concrete and the waste polystyrene foam board are utilized, and the influence of waste materials on the environment is reduced.

本发明公开了一种适用于砌体的再生保温材料的制备方法，包括粗骨料、细骨料、砂石、硅酸盐水泥和发泡剂，所述粗骨料是由废弃的聚苯乙烯泡沫板粉碎形成的大于5mm直径的颗粒，所述细骨料是由废弃的混凝土块碾碎筛选出的小于5mm直径的颗粒，所述硅酸盐水泥、细骨料和砂石以7∶2∶1的比例加水搅拌制成外层耐磨料，所述硅酸盐水泥、粗骨料和细骨料以7∶1∶2的比例加水搅拌并利用发泡剂发泡制成轻质保温料。该适用于砌体的再生保温材料的制备方法，利用废弃混凝土作为细骨料制配外层耐磨料和轻质保温料，同时利用废弃的聚苯乙烯泡沫颗粒作为粗骨料配制轻质保温料，对混凝土废料和废弃聚苯乙烯泡沫板进行了利用，减少了废弃材料对环境的影响。
