METHOD FOR PREPARING TEMPERATURE-CONTROLLING AND ENERGY-SAVING THERMAL INSULATION MATERIAL BY USING WASTE CONCRETE
Abstract Disclosed is a method for preparing a temperature-controlling and energy-saving thermal insulation material by using waste concrete, including: selecting a rectangular hollow plastic plate with open ends and sealing one of the open ends with polyurethane; then, injecting liquid phase change material into the rectangular hollow plastic plate; and plugging a cotton yarn fully soaked in polyurethane into the other one of the open ends of the rectangular hollow plastic plate to cure and sealing; obtaining recycled fine aggregate and recycled particles by crushing the waste concrete, and incorporating the recycled fine aggregate, the recycled particles, ordinary Portland cement and other materials to form an inorganic foam thermal insulation material; finally, putting the inorganic foam thermal insulation material, a cuboid airbag, and the rectangular hollow plastic plate into a prefabricated template, and maintaining at room temperature until a stadium, so as to finally obtain the temperature-controlling and energy-saving thermal insulation material. The building thermal insulation material not only recycles and reuses the waste concrete, but also has the advantages of small dead weight, good performance in thermal insulation, and self-controlling temperature.
