Description
Technical field
The present invention relates to a kind of foaming insulation boards, are suitable as construction material use, more particularly to a kind of micro- containing nanometer
Foaming insulation board of powder and preparation method thereof.
In recent years, as the gradual enhancing of people's environmental consciousness and country are more and more stringenter for environmental protection and energy saving requirement,
Energy-saving building technology and the promotion and popularization dynamics of material are also increasing.On June 1st, 2006, state lived the building of the portion's of building promulgation
Wall thermal insulating application technology regulation etc. plays certain impetus, while country will build to the development of building energy-saving heat-insulating material
Energy saving and green building is built to be included in 13 planning of country.
Building heat preservation product currently on the market mainly pastes materials'use with exterior wall, there is styrofoam, polyurethane, stone
The products such as cotton, but these materials have disadvantages that in itself, and the refractoriness such as styrofoam and polyurethane are low, will be caused when freeing fire
Wall, which catches fire, to bring about great losses, and asbestos material has human body certain harm, and these materials are to apply man-hour requirement complete in wall
It in addition constructs after work.The foam cement that this year grows up overcomes the shortcomings that more than heat insulating energy saving material to a certain extent,
The heat insulation effect of itself is also good, but most Foam cement insulation material has that intensity is not high, easy to crack broken.
