Abstract
The invention relates to an external wall fireproofing heat-insulation board and belongs to the field of low-carbon building materials. The external wall fireproofing heat-insulation board is prepared by the steps of: adding hydrophobic expended perlite with diameter of 2.0-30 mm to a magnesite cement cementing material in which a waterproof modification material is added, simultaneously adding aluminum hydroxide powder, then adding to a mold, curing at normal temperature, and demolding to obtain a finished product for external wall heat insulation.
Description
Affiliated field: the present invention is a kind of outer wall heat insulating and decorating plate, belongs to the low-carbon (LC) building materials field.
Background technology: existing external wall insulation adopts organic materials to pass through method realizations such as foaming more, and very easily burning also can generate a large amount of smog and toxic gas, the danger of this type material that a large amount of facts is verified under naked light.It is the light thermal-insulation filler as gelating material, with not so fine perlite that the present invention adopts magnesite material, is the fire protection flame retarding filler with the aluminium hydrate powder, can satisfy the request for utilization of exterior wall fireproof heat insulating.
Summary of the invention: the present invention is achieved in that the hydrophobic fine perlite that in having dosed the magnesia cement gelating material of water-repellent modified material, adds diameter 2.0--30 millimeter; Add aluminium hydrate powder simultaneously; Go into mould then and solidify at normal temperatures, the deburring shaping just becomes finished product after the demoulding.
Beneficial effect: the invention has the beneficial effects as follows; To have adopted the good white lake of flame retardant properties to carry out fire-retardant, improved the fire resistance that magnesia cement is used for exterior-wall heat insulation, and its effect can reach fully and not fire; Product not only can be used for exterior-wall heat insulation, also can be used for the fire-blocking belt.Its cost of cost is lower than organic insulation material, has enlarged the purposes of magnesite material.
Embodiment one prescription:
100 parts of magnesia unslackeds
80 parts of magnesium chloride solution 26 degree Beaume
0.5 part of tsp
4 parts of silicon sol
0.8 part of monocalcium phosphate
15 parts of aluminium hydrate powders
250 parts of fine perlites (Natural manganese dioxide parts by volume)
Material mixing promptly can be adorned mould after stirring, and solidifies the back demoulding.Be finished product after the demoulding.
Embodiment two prescriptions:
100 parts of magnesia unslackeds
80 parts of magnesium chloride 26 degree Beaume
0.25 part of phosphoric acid
4 parts of silicon sol
20 parts of aluminium hydrate powders
200 parts of fine perlites (Natural manganese dioxide parts by volume)
Technological process is identical with scheme one.
Claims (1)
1. magnesite exterior wall fireproof heated board.Through dosing the magnesia cement of water tight packing; Hydrophobic fine perlite, aluminium hydrate powder is characterized in that: in magnesia cement with the hydrophobic fine perlite as the thermal insulation layer filler, aluminium hydrate powder is as fire-retardant filler; Mix being stirred into mold forming, be used for the exterior wall fireproof heat insulating.
