Abstract
The utility model discloses a fire -resistant heat insulating cement board of high strength belongs to the building material field. Including the outer and cement mortar inlayer of cement mortar, be equipped with cement rock wool layer between cement mortar skin and the cement mortar inlayer, glass fiber thin slice felt is laid to the upper and lower side surface on cement rock wool layer, the cement mortar outside compounds or bonds fire -resistant concrete layer, cement mortar skin outside coating thermoreflectance heat insulating coat. The utility model discloses can improve the fire -resistant heat -proof quality of cement plate greatly, reduce thermal conduction, guarantee the stability of cement plate, laying glass fiber thin slice felt between cement rock wool layer and the cement mortar layer, can improving the intensity and the structural stability of cement plate effectively, protection cement rock wool layer uses the cement plate can not take place to fall scattered in long -time high temperature.
Description
Technical field
The utility model relates to a kind of cement board, is specifically a kind of high-strength fireproof insulating cement plate, belongs to building material field.
Background technology
Cement board is common constructional materials, and its easy construction, energy-conserving and environment-protective are promoted the use of widely in current building trade.In order to meet the fire prevention needs of specific buildings, at this type of constructure construction procedure usually with installing refractory cement plate, the extexine brushing fireprotection layer that existing refractory cement plate is typically employed in ordinary Portland cement plate realizes fire prevention, its intensity and fire resistance property is poor, heat conduction is fast; Particularly when breaking out of fire, cannot carry out effective heat isolation, cause heat conduction too fast, refractory cement plate can be scattered at short notice.In addition, existing refractory cement plate, when normally using, also cannot be incubated normally.
Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect and provides that a kind of intensity is high, the cement board of refractory heat-insulating good heat insulating.
In order to solve the problems of the technologies described above, the high-strength fireproof insulating cement plate that the utility model provides, comprise cement mortar skin and cement mortar internal layer, be provided with cement rock wool layer between described cement mortar skin and cement mortar internal layer, fiberglass sheets felt is laid on the upper and lower sides surface of described cement rock wool layer; Compound or bonding fire-resistant concrete layer outside described cement mortar, described cement mortar outer outer application heat-reflecting heat-insulating coating.
The beneficial effects of the utility model are: lateral surface that is outer in cement mortar and cement mortar internal layer arranges fire-resistant concrete layer, heat insulating coat hydrous water mud rock wool layer respectively, greatly can improve cement board refractory heat-insulating performance, reduce the conduction of heat, ensure the stability of cement board; Lay fiberglass sheets felt between cement rock wool layer and cement sand bed, effectively can improve intensity and the structural stability of cement board, protection cement rock wool layer, uses cement board can not be scattered in long-time high temperature.
In the utility model, the surface density of described cement rock wool layer is 170g/m
2, it can improve cement board fire-retardant heat insulation effect.
In the utility model, the thickness of described cement rock wool layer is greater than cement mortar skin and cement mortar internal layer, to ensure cement board fire-retardant heat insulation effect and intensity.
In the utility model, described fiberglass sheets felt surface in ripple struction, make itself and cement rock wool layer, cement sand bed connection more reliable and more stable.
Accompanying drawing explanation
Fig. 1 is the utility model high-strength fireproof insulating cement plated construction schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model high-strength fireproof insulating cement plate, cement mortar internal layer 1, lower-glass sheets of fibres felt 2, cement rock wool layer 3, upper fiberglass sheets felt 4, cement mortar skin 5, fire-resistant concrete layer 6 and heat-reflecting heat-insulating coating 7.The soffit coating heat-reflecting heat-insulating coating 7 of cement mortar internal layer 1, the upper surface adhering glass sheets of fibres felt 2 of cement mortar internal layer 1, fiberglass sheets felt 2 upper surface binder clay rock wool layer 3, the bonding upper fiberglass sheets felt 4 of upper surface of cement rock wool layer 3, upper fiberglass sheets felt 4 upper surface bonding cement mortar skin 5, the outer bonding upper compound of 5 upper surface of cement mortar or bonding fire-resistant concrete layer 6.
In cement rock wool layer 2, the surface density of rock wool can regulate as required, and through comparing, the surface density of rock wool is 170g/m
2cement board fire-retardant, thermal and insulating performance is relatively better.In the present embodiment, the thickness of the cotton layer 2 of cement is 8mm, and the thickness of cement mortar internal layer 1 and cement mortar skin 5 is 5mm, and the thickness of fire-resistant concrete layer 6 is 3mm.
The surface of lower-glass sheets of fibres felt 2 and upper fiberglass sheets felt 4 all in ripple struction, to ensure the stability be connected with between cement rock wool layer, cement sand bed.
In the present embodiment, fire-resistant concrete layer 6 is made up of each composition of following weight portion: slag 20-30 part, bauxite 11-15 part, aluminate cement 17-23 part, water glass 11-15 part, silicon ash 10-16 part, melamine based water reducer 6-9 part.Heat-reflecting heat-insulating coating 7 adopts heat-reflecting heat-insulating Material coating common in prior art.
The rock wool that it should be known that in above-mentioned cement rock wool layer as those of ordinary skill in the art also can adopt ceramic wool or resistance to guncotton to substitute.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
