Technical field
The utility model belongs to building material field, particularly a kind of inorganic foamed warming plate for external wall.
Background technology
At present, in order better to realize building energy conservation, at external wall, all a kind of heat-insulating heat-preserving material can be set, common heat-insulating heat-preserving material is polystyrene foam plate, phenolic foam board, the high-molecular organic materials such as polyurethane foam board or inorganic light weight foam concrete plate, foam glass board, because organic polymer thermal insulative material exists fire-protection rating lower, the problems such as mineral-type heat insulating material coefficient of thermal conductivity and water absorption rate are higher, therefore along with the progress of current science and technology, people are also constantly research and probe fire-protection rating is higher, heat insulating effect is better, the external wall inorganic heat insulation material that water absorption rate is lower.
Summary of the invention
The purpose of this utility model is to propose a kind of warming plate technical scheme for external wall, utilizing aerosil is the A level fireproof heat insulating heat-barrier material that a kind of water absorption rate is low, thermal and insulating performance is superior, be coated in the external surface of inorganic heat-insulation board, by adopting simple technique to promote the thermal insulation level of traditional warming plate.
To achieve these goals, the technical solution of the utility model is: a kind of inorganic foamed warming plate for external wall, comprise concrete slab, and wherein, on six faces of described concrete slab, be respectively arranged with layer of silicon dioxide aeroge.
Scheme is further: described aerosil be by spraying and adhesive bonding on six faces of foam concrete plate.
Scheme is further: the thickness of described aerosil is 1mm to 2mm.
Scheme is further: the thickness of described aerosil is 1.5mm.
Scheme is further: described aerosil is that density is 100-370Kg/m
3aerosil.
Scheme is further: the density of described aerosil is 300Kg/m
3aerosil.
Scheme is further: described concrete slab is inorganic light weight cement board or foam concrete plate.
The utility model can be prepared at normal temperatures, without special constant temperature and pressure equipment, production technology is simple, can be handling strong, the traditional foam concrete plate of thermal conductivity ratio can reduce by 10～30%, the A1 level fire-protection rating that meets GB8624-2006 < < constructional materials and goods classification system for fire performance > >, has lower coefficient of thermal conductivity, water resistance and good thermal and insulating performance.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
For an inorganic foamed warming plate embodiment for external wall, referring to Fig. 1, described warming plate comprises concrete slab 1, wherein, on six faces of described concrete slab, is respectively arranged with layer of silicon dioxide aeroge 2.
In embodiment: described aerosil be by spraying and adhesive bonding on six faces of foam concrete plate.
In embodiment, the thickness of described aerosil is 1mm to 2mm.As one preferably: the thickness of described aerosil is 1.5mm.
In embodiment: described aerosil is that density is 100-370Kg/m
3aerosil.
In embodiment, as one preferably: the density of described aerosil is 300Kg/m
3aerosil.
In embodiment: described concrete slab is inorganic light weight cement board or foam concrete plate.
For aerosil being bonded in closely to the external surface of concrete slab, on six faces of concrete slab, by blasting treatment, be provided with pit.
Aerosil is the A level fire-proof heat-insulating material that a kind of water absorption rate is low, heat-insulating property is superior; its coefficient of thermal conductivity is generally at 0.013～0.03W/ (m.K), far below inorganic heat insulation material on market, as rock cotton board; glass bead insulation plate, foamed cement board, foam glass board.Aeroge is because of its complicated process of preparation and with high content of technology at present, and only in Aero-Space, apply the high-end fields such as military project, and along with going deep into of research, aeroge has been applied to the fields such as insulation of equipment, industrial pipeline insulation gradually.Aerogel material has good thermal and insulating performance and fireproof performance, is the desirable substitute products of traditional heat insulating material.But the block that uses separately aerosil to make is crisp, loose, and intensity is low, and cost is higher, be difficult to independent use.
Described foam concrete in embodiment is to adopt blowing agent to mix casting system with cement paste, and described blowing agent is hydrogen peroxide, and described aerosil coating is a kind of solution fully being mixed with surfactant by aerosil;
Described surfactant refers to: the mixing of methyl cellulose ether, hydroxyethylmethyl-cellulose ether, TYLOSE 30000, hydroxyethyl ether cellulose, hydroxypropyl methyl cellulose ether a kind of or 2 kinds, mixed proportion is any.
Concrete slab size in embodiment, for example foam concrete board size is normally: length is 3 meters, and wide is 0.6 meter, and thickness is 70 millimeters to 100 millimeters.
Because aeroge has good hydrophobicity, cannot directly be added to the water, be not suitable for traditional foam concrete production technology.Therefore the present embodiment is coated to aerosil on 6 surfaces of foam concrete, and coating layer thickness is 2mm.Compare with traditional foam concrete, production technology is simple, can be handling strong, with low cost, combustibility can reach the A1 level in GB8624-2006 < < constructional materials and goods classification system for fire performance > >, has lower coefficient of thermal conductivity, water resistance and good thermal and insulating performance.
