Abstract
The invention discloses a high-strength fireproof and thermal-insulation cement board, and belongs to the field of building materials. The high-strength fireproof and thermal-insulation cement board comprises a cement mortar outer layer and a cement mortar inner layer; a cement rock wool layer is arranged between the cement mortar outer layer and the cement mortar inner layer; glass fiber thin felts are paved on surfaces of the upper side and the lower side of the cement rock wool layer respectively; a fireproof concrete layer is compounded or adhered to the cement mortar outer layer; and a heat-reflection thermal-insulation coating coats the outer side of the cement mortar outer layer. Fireproof and thermal-insulation properties of the cement board can be greatly improved, heat conduction can be reduced, and stability of the cement board is guaranteed; and the glass fiber thin felts are paved between the cement rock wool layer and the cement mortar layer, the strength and the structure stability of the cement board can be improved effectively, the cement rock wool layer is protected, and the cement board cannot fall into pieces even if the cement board is used in a high-temperature environment for a long time.
Description
Technical field
The present invention relates to a kind of cement board, be specifically a kind of high-strength fireproof insulating cement plate, belong 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.
Summary of the invention
Technical problem to be solved by this invention 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, high-strength fireproof insulating cement plate provided by the invention, 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.
Beneficial effect of the present invention is: 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 present invention, 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 present invention, 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 present invention, 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 high-strength fireproof insulating cement plated construction schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, high-strength fireproof insulating cement plate of the present invention, 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 the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
