Problems solved by technology

There is also such a problem with inorganic thermal insulation mortar, and the water absorption rate of these products is relatively large, mainly because the water absorption rate of perlite itself is too large, which is 200 to 300 times that of itself.

Abstract

The invention relates to an inorganic foaming cement heat insulation board and a fabrication method thereof. The inorganic foaming cement heat insulation board comprises cement slurry and foaming agent slurry, wherein the cement slurry comprises the following components by weight percentage: 40-60% of cement, 10-30% of coal ash, 0-20% of nano hollow microbeads and 0-5% of additive, and the weight percentage of the foaming agent slurry is 1-5%. The heat insulation board has the benefits that as an outer heat insulation system product for an outer wall, the inorganic foaming cement heat insulation board is light and fire-proof; the heat insulation property of the inorganic foaming cement heat insulation board is greatly improved; the dead weight is reduced; the safety of the inorganic foaming cement heat insulation board after being arranged on a wall is ensured; and the heat insulation board has the characteristics of environmental protection, economy and the like.

Description

Technical field [0001] The invention relates to a building material, in particular to an inorganic foamed cement insulation board and a preparation method thereof. The inorganic foamed cement insulation board can be used in an external wall external insulation system. Background technique [0002] As the country pays more and more attention to energy-saving work, this means that not only new buildings must meet energy-saving standards, but also the energy-saving renovation of existing buildings must be intensified. People are paying more and more attention to building energy-saving issues, increasing environmental protection concepts and safety awareness Gradually increasing, traditional inorganic insulation boards have the disadvantages and problems of high density, high thermal conductivity, and poor insulation effect. For example: the density of lightweight expanded perlite insulation board is 400~600kg / m 3 If the density is too small, there will be no strength, of course the ...
