Abstract
The invention relates to a foamed concrete plate and a preparation method thereof. The foamed concrete plate is characterized by being composed of the following components: early strength sulfo-aluminate cement, fly ash (two grade or higher), a calcium stearate foam stabilizer, a melamine water reducer, polypropylene fiber, industrial magnesium chloride, aluminum chloride, hydrogen peroxide, and the balance being water. The total weight percentage of the components mentioned above is 100%. The cement foamed plate has the same service life as that of a building. The fireproof and thermal insulation level can reach A1 grade. Moreover, the foamed concrete plate has the advantages of high bonding strength, good weatherability, and low thermal conductive coefficient. The raw materials such as sulfo-aluminate cement and fly ash are environment-friendly materials. The foamed concrete plate is accord with the national industry policy, has a good development prospect, and can replace the conventional products. The foamed concrete plate can be applied to wall thermal insulation in civil or industrial buildings. The thickness of thermal insulation layers can be calculated according to the present design standards for energy efficiency of buildings or city building energy efficiency requirements through heat engineering calculation.
Description
Technical field
The present invention relates to a kind of cement board and preparation method thereof.
Background technology
In current building structure, large-scale buildings is much skeleton construction, and floor is cast-in-place, also some small buildings are had to be built in stand column and beam by the cement grillage made in addition, howsoever, current cement plate is solid, without insulation effect.In recent years along with Economic development, people improve for the urgency of the cold and heat supply in summer and winter, and northern area has more than half a year to need boiler heat supplying every year, also coal firing boiler polluted air is caused thus, cause some big city atmospheric pollutions of the north, here the warming requirement for buildings just considerably increases, and some warming measures are at present only limitted to overlay in appearance warming layer, but inadequate for the warm-keeping protective of floor.Some places have started to adopt factorial praluction building now in addition, it is exactly the body of wall in factory by buildings, compartment comprises floor and all prepares, then by vehicles drive to building site, field assembly, greatly accelerate building operation, also save a large amount of durations, again need not wait the time of the dry and hard so pure consumption of cement concrete, also save artificial in addition, and just need to develop for this reason can be warming building block, if the cement plate that can be incubated can be designed and developed out, and be made into the body of wall of buildings, compartment, floor, then will greatly strengthen the heat retention of buildings, also thermal insulation layer is overlayed again after buildings need not be waited to build up, therefore developing the cement board that can be incubated will be the developing direction of building trade.
Summary of the invention
The object of the invention is to solve cement plate in prior art is solid existing the problems referred to above, provides a kind of cement board and preparation method thereof.The present invention designs a kind of cement board and preparation method thereof, it is characterized in that being made up of following composition and weight percent:
