Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of wall thermal insulating slurry and preparation method thereof and not
Combustion wall heat insulation material.
Background technology
External thermal insulation system is constituted by heat-insulation layer, protective layer and fixing material (adhesive, anchoring piece etc.) and is suitable for
General name is constructed in the non-bearing heat-preserving being arranged on exterior wall surface.External wall outer insulation can alleviate the impact of cold bridge, protects master simultaneously
Body walling by great temperature degeneration stress, is not made that huge contribution in terms of building energy conservation, is current China building wall
The energy-saving technological measure being most widely used in energy-saving, is also the insulation way vigorously advocated of current country.
At present, it is applied to the external thermal insulation system of China and mainly has following several form: expansion polystyrene plate (EPS)
Thin-coat plaster wall outer heat preservation system, large die built-in (having net, without net) external thermal insulation system, glue powder polyphenyl granule exterior wall external thermal insulation system
System, polyurethane (spraying, sheet material) external thermal insulation system, extruded sheet (XPS) external thermal insulation system etc..Wherein EPS sheet is with valency
The advantages such as lattice are cheap, construction is simple occupy the biggest share in insulation market.
PS foam plastics belongs to combustible material, and its limited oxygen index is only 10%, decomposes and produce styrene monomer, benzene after meeting fire
Ethylene dimerization body and Hydrocarbon (such as benzene, low alkylbenzene and a small amount of oxygen-containing aromatic etc.), have preferable calorific value.PS
Being easily generated the melted drippage of band naked light during foam plastics burning, it is possible to ignite other combustibles, remaining to continue even if removing burning things which may cause a fire disaster
Burning, is therefore stacking and easily breaking out of fire in building construction process.The modal example of polystyrene foam flame-retardant additive
Son is organohalogen compound such as HBCD.The common ground that these examples have is that product reacted with the fiery first stage
Control is the best, but under the higher temperature in sustained fire situation, the polystyrene of interiors of products will melt, and causes
Caving in of foaming structure and the most whole product structure.
Summary of the invention
The present invention proposes a kind of wall thermal insulating slurry, it wall heat insulation material formed, not only combustibility reaches A level
The standard of incombustible material, and there is higher intensity.
The technical scheme is that and be achieved in that:
