Description

A kind of foamed cement composite floor board and preparation method thereof of modified fibre enhancing
Technical field
The present invention relates to building material technical fields, and in particular to a kind of foamed cement composite floor board of modified fibre enhancing And preparation method thereof.
Background technique
Composite floor board is the one of which on floor.But composite floor board is artificially changed the natural structure of flooring material, is reached The floor that a certain physical property meets the expected requirements.It is multiple that composite floor board often refers to reinforced composite wooden floor, solid wood on the market Close floor.
Foamed cement is that foaming agent is mechanically sufficiently foamed by the foamed system of foaming machine, and by foam and water Then mud slurry uniform mixing carries out cast-in-place construction or mold molding by the pumping system of foaming machine, is formed through natural curing A kind of novel light insulation material containing a large amount of sealed porositys.It belongs to air bubble-shaped heat-insulating material, and outstanding feature is mixed Solidifying soil is internal to form closed foam hole, makes concrete light and thermal insulation separation thermalization.
As building energy conservation promotes desired raising to building thermal technique performance and green building, except exterior-wall heat insulation obtains comprehensively Outside promoting the use of, ground insulating and sound insulation are also gradually taken seriously, and in the prior art, are come with reinforced composite wooden floor mostly It realizes, but reinforced composite wooden floor is to carry out bedding in the house fitting-up in later period；And because reinforced composite wooden floor Higher cost, nowadays, there is an urgent need to one kind have that light weight, intensity are high, can be used as ground cushion again and have it is excellent keep the temperature, every Floor early period of acoustic performance.
Ground insulating mostly uses the materials such as cast-in-place foamed concrete, benzene plate, full lightweight concrete at present, but cast-in-place foamed mixed Solidifying soil because slurry laminated segregation cause to gather materials, the typical sandwich structure such as net slurry, foam and cause hollowing, serious cracking. The thermal coefficient of benzene plate is low, good heat-insulation effect, but there is also easily by compressive deformation, and fatigue strength is deformed, thermal coefficient The disadvantages of rising.And full lightweight concrete makes its quality be difficult to monitor because of the reasons such as light-weight aggregate property variation, unstable, multicomponent.
Summary of the invention
In view of the above problems, there is provided a kind of at low cost, quality for first technical problem that the present invention solves The foamed cement composite floor board of light modified fibre enhancing, there is provided a kind of modifications for another technical problem that the present invention solves The preparation method of fibre-reinforced foamed cement composite floor board.
In order to solve the first technical problem mentioned above, the technical scheme is that：A kind of foaming water of modified fibre enhancing Mud composite floor board mainly includes wearing layer, decorative layer, insulating layer and interface articulamentum；The decorative layer is arranged described wear-resisting Below layer, the insulating layer is arranged below decorative layer, and the interface articulamentum is arranged below insulating layer；
