Description

Composite fire insulation board

technical field

The utility model relates to an external wall heat preservation system, in particular to a composite fireproof heat preservation board.

Background technique

An inorganic hard thermal insulation material used in external walls for thermal insulation must be able to meet the requirements of high strength, high thermal insulation effect, excellent construction performance, and low price within a relatively low bulk density range. However, the contradiction between low bulk density, low thermal conductivity and high strength of inorganic rigid thermal insulation materials on the market has always been an insurmountable technical problem, which directly affects the application and promotion of this kind of material. External wall insulation systems based on these common inorganic insulation materials in the market are often difficult to combine the characteristics of low bulk density, low thermal conductivity and high strength. In addition, as an exterior wall, users very much hope that it has good waterproof and anti-seepage properties and good noise absorption characteristics. These requirements are not met by the common external wall insulation systems currently on the market. As an important aspect of building energy conservation, the external wall insulation system meets the urgent needs of current building energy conservation and also meets the current national policy if it can meet the above requirements.

Wherein preferably, the proportioning of the cement mortar used as the cement mortar layer of the bonding layer is cement:sand=1:3.5, and the average thickness of the cement mortar layer is 15 mm.

Preferably, the material used for the first protective layer is crack-resistant mortar with an average thickness of 2 mm.

Preferably, the material used for the second protective layer is polymer anti-crack mortar, with an average thickness of 2±0.5mm.

The above-mentioned external wall insulation system has the following advantages:

1. The external wall insulation system with composite fire insulation board insulation layer has excellent construction performance, and the system has good compatibility between layers. After testing, the bonding force between the external wall fireproof insulation board and the wall reaches 0.4Mpa, which is 2-2.5 times that of the organic insulation board. In addition, because the size of the micropores of the external wall fireproof insulation board is strictly controlled and specially treated, it has a better bonding effect than ordinary inorganic hard insulation materials and organic insulation boards, and there is no hollowing and cracking phenomenon, and the system is load-resistant. Wind pressure (suction) capacity is stronger.
