Porous thermal insulation material and preparation method thereof
The invention belongs to the technical field of thermal insulation materials, and discloses a porous thermal insulation material and a preparation method thereof. Secondary aluminum ash generated in the bauxite smelting process is used for replacing a traditional chemical foaming agent to prepare the fly ash-based geopolymer porous thermal insulation material, and the thermal insulation material is prepared by regulating and controlling parameters such as the ratio of the raw materials, the modulus of the alkali activator, the stirring mode and the maintenance mode. The porous thermal insulation material with high compressive strength, good durability, high porosity and excellent thermal insulation performance is prepared. Through detection, the porosity of the prepared porous thermal insulation material is greater than 90%, the compressive strength reaches 0.44 MPa, the heat conductivity coefficient is 0.063 W/(m.K), and the performance is excellent.
