Description

A kind of A level fire-retardant heat-insulation material and production unit and method
Technical field
The invention belongs to external wall fire-retardant heat-insulation material technical field, be specifically related to a kind of A level fire-retardant heat-insulation material and production unit and method.
Background technology
For a long time, generally use polystyrene foam (EPS, XPS), rigid polyurethane foam organic insulation materials such as (PU) on the construction market, it has advantages such as lightweight, high insulating effect, but inflammable, easy aging, poor durability, various places heat-preserving building engineering presence of fire accident repeatedly, will soon melt during fire, smog is big, toxicity is big, be difficult to put out a fire to save life and property, and harm is serious.
In recent years, people adopt the method in organic insulation material outside surface coating inorganic materials to increase its fire line, use maximum polyphenyl plate thin plastering systems that surely belong to.But the inorganic materials of smearing very easily comes off, and makes organic materials easily aging, can't with the same life-span of buildings.Repeatedly change not only wasting manpower and material resources, and cause white pollution.
Application number is to have put down in writing a kind of EPS fireproof heated board in 201210296618.8 the Chinese invention patent application documents, this fireproof heated board by the Expandable Polystyrene (EPS) masterbatch pellet through steam pre-frothing, again that the granules of polystyrene of prefabricated fire retardant slurry and pre-frothing is even according to the mixed of weight ratio 1: 2-4, oven dry, with steam molding, cooling and demolding, obtain product through cutting.Because difference such as the shrinkage coefficient of granules of polystyrene and fire retardant slurry, thermal conductivity are bigger, cause crisp, the easy suction of this product, heat retaining property poor.
Application number is to have put down in writing a kind of polystyrene foam plate and preparation method thereof in 200810061225.2 the Chinese invention patent application documents.This method at first is foamed into the light foam particle with the polystyrene plastic particle by steam; Then dispose magnesia oxychloride cement; Then polystyrene plastic particle and magnesia oxychloride cement are fully stirred and close, make the foam particle surface coat magnesia oxychloride cement; At last the foam particle that mixes is made the magnesia oxychloride cement polystyrene foam plate.Can also be after making the magnesia oxychloride cement polystyrene foam plate, again at the inorganic adhesive-layer of its two surface recombination.This product is not only heavy, is unfavorable for the transportation installation, and the same crisp problem of existence.
Application number is to have put down in writing a kind of polyphenyl board cavity-free fireproofing external wall thermal insulation system in 201010194204.5 the Chinese invention patent application documents.This heat-insulation system is from the inside to the outside by adhesive linkage, thermal insulation layer, and screed-coat, the cracking resistance protective layer, upper layer is formed; Adhesive linkage is made up of boundary mortar and glue powder polyphenyl particle bonding heat preservation slurry; Described thermal insulation layer is the diplopore styrofoam of handling through the styrofoam boundary mortar, and this plate face has dovetail groove, and its thickness is 30-60mm, adopts between the diplopore styrofoam and divides chamber structure.Though this heat-insulation system is making moderate progress aspect insulation and the fire prevention than present existing technology, still has some problems: because it adopts the mode of fluting, the overall performance heterogeneity of warming plate, bulk strength is lower; Because it adopts multilayered structure, has increased the manpower and materials cost undoubtedly; Each layer adopts differing materials, and what be separated from each other between each layer may be still bigger, thereby influenced the weather resistance of lagging material, and then influence heat retaining property.
