Description
Technical field
The present invention relates under a kind of room temperature curing condition can fast demoulding heat-insulation wall plate material and preparation method, belong to
In building material field.It solving the problems, such as that the heat-insulation wall plate production cycle is grown more particularly to a kind of, is mainly used for assembled architecture guarantor
The preparation of warm wallboard.
Background technology
Building industrialization and housing industrialization and Urbanization Construction require actively to promote prefabricated construction.For building
Building enclosure, it is exactly the assembling degree of wall to examine the key index of building industrialization level.Promote and apply assembled light
Heat insulating type concrete Side fascia meets the industrial policy of national green building and building energy conservation, is that building trade realizes sustainable development
Open up the important content of strategy.
Assembling thermal-insulating wall board is building industrialization important component.Current assembling thermal-insulating wall board is general to use
Portland cement makes, and there is the shortcomings that condensation hardening is slow, demoulding time is long, low production efficiency.Many enterprises are in order to add
Fast production efficiency shortens striking time using steam-cured method, but this needs complicated steaming and cultivating equipment, enterprise to need to put into
Huge fund；In addition it needs to consume a large amount of energy in maintenance processes, significantly increases enterprise's production cost.Above-mentioned reason
All significantly limit popularization and application of the existing assembling thermal-insulating wall board in building industrialization, be badly in need of wanting it is a kind of can fast demoulding
Assembling thermal-insulating wall board material and preparation method thereof.
Invention content
For the deficiency present in existing assembling thermal-insulating wall board material, the present invention proposes under a kind of room temperature curing condition
Can fast demoulding heat-insulation wall plate material and preparation method, technical solution be：
Under a kind of room temperature curing condition can fast demoulding heat-insulation wall plate material and preparation method, wrap by mass percentage
Include following substance：
The light-burning magnesium powder activity ＞ 60%, 200 mesh of fineness ＜, free CaO content ＜ 2%, Fe2O3Content ＜ 1.5%..

The flyash is dark gray powder, SiO2Content is between 50%~65%, Al2O3Content between 20%~
45%, mean particle size is at 0.5~300 μm, and bulk density is between 500kg/m3~1300kg/m3.Fly ash grain is circle
Smooth glass plastid can play ball effect, improve the mobility of concrete, while can also increase cohesiveness.Flyash adds
The setting time of magnesia oxychloride cement can also be adjusted by entering, and be extended as volume increases setting time.
The cinder is the waste residue that thermal power plant, industry and civil boiler and other equipment fire coal are discharged.Coal slag granules
Average grain diameter is in 1.0~6.0mm, and bulk density is between 460kg/m3~840kg/m3.Contain a large amount of holes inside cinder, therefore
Grain density is smaller, light, and the incorporation of cinder can significantly reduce the density of heat-insulation wall plate, reduces weight, while a large amount of holes
Introducing, the heat-insulating property and sound insulation property of assembling thermal-insulating wall board can be improved.
