Abstract

The invention discloses a solar heat absorption and release ardealite insulation board and a preparation method thereof. The insulation board is prepared through the steps of preparation of ardealite powder, preparation of a black material, preparation of a white material, demolding and the like, and the insulation board is a light material prepared by taking ardealite waste residues as a main raw material. The insulation board is a building material with light weight, higher strength, designable thickness and good sound insulation, heat insulation, fire prevention and the like, is one of novel lightweight high-efficiency thermal insulation boards which are emphatically developed at present, and is simple in preparation method process, low in cost and excellent in performance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a solar heat-absorbing and exothermic phosphogypsum insulation board and a preparation method thereof. Background technique [0002] Phosphogypsum is a by-product of wet process production of phosphoric acid, and its main chemical composition is dihydrate gypsum (CaSO4·2H2O). At present, the disposal of phosphogypsum at home and abroad is mostly waste accumulation, resulting in serious waste of resources and environmental pollution. In recent years, although some scholars have researched some methods of utilizing phosphogypsum, the effect is not very satisfactory. Therefore, seeking effective phosphogypsum utilization methods and improving the comprehensive utilization rate of phosphogypsum has become a major problem to be solved urgently by phosphorus chemical enterprises and environmental protection departments. The resource utilization of phosphogypsum...
