Light geopolymer thermal insulation material and preparation method thereof
The invention relates to a light geopolymer thermal insulation material and a preparation method thereof, in particular to a light geopolymer thermal insulation material and a preparation method thereof. The invention aims to solve the problems of poor durability and poor compressive strength of existing foam concrete, and high cost of a preparation method and no environmental protection. The thermal insulation material is composed of fly ash, metakaolin, sodium hydroxide, water glass, water, a foaming agent, a foam stabilizer and lightweight aggregate. The preparation method comprises the following steps: uniformly stirring and mixing the fly ash and metakaolin dry materials, adding the alkali activator and water, stirring to obtain geopolymer slurry, adding the foaming agent and the foamstabilizer into the slurry, quickly stirring, adding the lightweight aggregate, continuously stirring, uniformly mixing to obtain geopolymer foam concrete slurry, and finally carrying out injection molding, demolding and room-temperature curing. According to the invention, the green geopolymer foam concrete with high strength, light weight and good thermal insulation property is obtained. The invention is applied to the technical field of building materials.
