Description
Technical field
The present invention relates to a kind of engineering material technical field, particularly to a kind of pure crystallite and crystallite mixed foaming
Composite plate integral sintering technique.
Background technology
Ornament materials and fire prevention heat insulating material for external are always the main class of architecture engineering material technical field research
Topic, heat-insulation layer can be described as the fat of building, it is possible to achieve the energy-saving effect of building, and decorative layer is built exactly
The skin built, can set off out the beauty of building.Substantially whole construction contents of external wall are all around
Heat-insulation layer and decorative layer the two emphasis do.Generally external wall includes multi-ply construction, depends on outward from interior
Secondary for body of wall, screed-coat, heat-insulation layer, overcoat and decorative layer, its constructing structure level is many, operating expenses
Costliness, construction requirement is high, long in time limit, and building cost and construction period are suffered from important impact.
External-wall heat-insulation material conventional in the market has polystyrene foam plate, polystyrene agent to mould plate, rock
Cotton plate, mineral wool board, blanket of glass wool, expanded perlite, expanded vermiculite, foam cement, building waste foaming
Plate etc..This type of material the most all exist easily burn, toxic gas, physical and chemical stability are poor, the most aging,
Service life is short, organic insulation material does not mates with inorganic metope, easily shrink deformation, constructional difficulties etc.
Problem.Building in recent years catches fire case, relevant more than external-wall heat-insulation material, according to " protecting outside civil buildings
Temperature system and decoration of exterior wall fire prevention temporary provisions " (public logical word [2009] 46) Article 2 regulation, civil buildings
The material that heat insulating material for external uses combustibility to be A level.It is well known that general insulation material is anti-
Fire performance is the best, and heat-insulating property is the poorest, so under the requirement of equal insulation levels, heat-insulation layer must add
Thickness, this is tantamount to and has increased the weight of cost and the design difficulty of building itself.
Crystallite foaming material is the insulation material of a kind of high-grade environmental protection newly developed on market, is recycling
The solid waste such as desert wind sand, gangue, flyash, various mine tailing slag, building waste, create
The turning harm into good of property, the green material produced of turning waste into wealth.It has fireproof heat insulating, heat conductivity
Low, stable chemical performance, nonpoisonous and tasteless, anticorrosion is moistureproof, sound insulation and noise reduction, possesses fabulous waterproof hydrophobicity
Can and the characteristic, the especially resistance to compression of foaming thermal-insulating lightweight such as Vermins-proof mildew-proof, weatherability be strong, structural strength is high,
It is significantly larger than other insulation material of same domain service life, multiple field can be widely applied to.
In sum, produce that the fireproof heat insulating that has, heat conductivity be low, stable chemical performance, nontoxic nothing
The protection against the tide of taste, anticorrosion, sound insulation and noise reduction, to possess fabulous waterproof hydrophobicity performance and Vermins-proof mildew-proof, weatherability strong etc.
Characteristic, can have the highest superiority as the composite board of decoration alien invasion again, not only can improve building skill
Art, and can solve large quantities of because desert wind sand, gangue, flyash, various mine tailing slag, building
The environmental problem that building refuse brings, has the biggest market and utilizes and Development volue.
