Abstract

The invention relates to a phase-change energy-storage inorganic foam fireproof thermal-insulation board and a preparation method thereof. The production technique of the fireproof thermal-insulation board is simple and can easily implement industrialized production; the prepared fireproof thermal-insulation board is a porous inorganic board having low heat conductivity coefficient and favorable thermal insulation property, is suitable for casting roofing, floor and internal and external walling of a building, and can also be used as various thermal-insulation board core materials and used for making various fireproof door core boards and fireproof isolation belts. The fireproof thermal-insulation board is an inorganic non-inflammable board, and completely satisfies the national construction material fireproof grade requirements. The fireproof thermal-insulation board is subjected to deep processing with Portland cement, so that the characteristics of the Portland cement are fully displayed, the strength of the original material is enhanced; and thus, the pore wall of the board is thinner and has toughness, and has lighter volume weight on the premise of not lowering the board strength, thereby lowering the heat conductivity coefficient and enhancing the thermal insulation effect.

Description

technical field [0001] The invention relates to a phase-change energy-storage inorganic foamed fire-proof insulation board and a preparation method thereof, belonging to the field of energy-saving building materials. Background technique [0002] At present, 80% of the insulation materials in the field of building energy-saving materials in my country use flammable materials that have been restricted or banned in Europe and the United States. Occurs frequently, posing a great threat to the safety of people's lives and property. For this reason, in recent years, relevant state departments have issued a series of mandatory policies, regulations, and standards on the fire resistance of building energy-saving materials, all of which require non-combustible insulation materials or flame-retardant insulation materials to be selected in new buildings, and inorganic insulation materials are used as non-combustible materials. It is undoubtedly the best choice for building insulation ...
