Composite heat-insulation board and preparation method thereof
The invention provides a novel composite heat-insulation board and its preparation method. Solid waste fly ash which is used as a main raw material undergoes one-time sintering to obtain the composite heat-insulation board. By the method for preparation of the composite heat-insulation board, the present situation of low comprehensive utilization rate of fly ash and environmental pollution is solved; and as a matrix layer and a heat-insulation layer both adopt the solid waste fly ash, costs of the composite heat-insulation board are greatly reduced, and added value of fly ash product utilization is raised. After one-step sintering, the matrix layer and the heat-insulation layer are greatly combined, and no binding material is needed. Thus, the matrix and the heat-insulation layer are sintered at a time to be integrated. According to the invention, resource utilization of garbage materials is realized, and field resources for fly ash landfill are minimized. The composite heat-insulation board meets requirements of energy conservation, waste utilization and environmental protection. In addition, the prepared composite heat-insulation board has high strength, good fireproof and heat-insulation properties, is resistant to water and insect pest, is conducive to popularization and application in practice and is of great economic, social and eco-environment protection significance.
