The preparation method comprises the following steps: weighting an adhesive, a water repellent and a curing agent according to weight and placing in a stirring device for stirring to obtain a first premix; weighting perlite, a filling material, a reinforce and a flexibilizer according to weight and placing in the stirring device for stirring to obtain a second premix; placing the first premix and the second premix in a mixing device for mixing to obtain a mixture; introducing the mixture in a cold press with a die for cold press molding to obtain a slab, sending the slab to a drying room for drying to obtain a fireproof flame retardation plate body; foaming thermoset polyurethane on surface of one side of the fireproof flame retardation plate body, and then introducing in a high speed laminating machine for compression moulding to obtain the finished product. According to the invention, industrial amplification production requirement can be satisfied, the heat insulation effect is excellent; the fireproof grade can reach A1 grade requirement; the fireproof flame retardation warming plate can completely be taken as a decorative plate for the exterior wall of the building, and make the building to have outstanding energy saving and fireproof performances.
Description
Technical field
The invention belongs to building decoration decorative materials preparing technical field, be specifically related to the preparation method of a kind of skin with the fire protection flame retarding warming plate.
Background technology
As the industry's knowledge of the reason, directly on the body of wall (exterior wall) of buildings, be sticked finishing material for example marble or other similar material only play the cosmetic decoration effect, and can not play heat-insulation and heat-preservation and fp effect.The heat transfer coefficient of skin finishing material is less, just more embodies energy-conservationly, and for example, in extremely hot summer, because of the external world extremely hot, to be passed to indoor degree less, and indoor the and outdoor temperature difference is larger, so, when indoor use air-conditioning, but just saving heat energy; Otherwise, when cold winter, because room temp is difficult for being passed to the external world, thereby can guarantee that room temp is significantly higher than outdoor environment temperature, so while enabling air-conditioning or heating installation, can embody equally energy-conservation when indoor.
About skin, by the technical intelligence of fireproof heat insulation plate, can in disclosed Chinese patent literature, be seen in, slightly with what exemplify, recommend to have " a kind of fireproof heat insulating board for exterior walls " as practical new patent Granted publication CN201598743U, the fireproofing outer with being compounded in thermal insulation layer by thermal insulation layer forms, fireproofing is three-decker, screed and the grid cloth between the screed on two sides by two sides forms, thermal insulation layer is EPS, i.e. polystyrene.
Granted publication CN201722808U introduces " fire-proof isolated composite insulation board ", by the inorganic panel of both sides, the warming plate of being taken on by EPS plate, XPS plate, PU plate or resol plate between inorganic panel and the rock cotton board between warming plate, formed, wherein, rock cotton board warming plate is divided into two (separating).
Granted publication CN201943300U provides " fireproof heat insulation plate that skin is used ", by plate body and the fire-proof and thermal-insulation thermal insulation layer that is incorporated into plate body one side, in the material prescription of fire-proof and thermal-insulation thermal insulation layer, is mixed with granules of polystyrene.Again, " skin fireproof heat insulation plate " that " the skin fireproof heat insulation plate " that CN202073256U discloses and CN202073198U disclose all selected with polystyrene is arranged.
The common feature that is not limited to the above-mentioned patent exemplified is owing to having used the comparatively excellent polystyrene of heat-insulating property, thereby has the heat-insulating property good to buildings, thereby is embodied the energy-conservation of buildings.
Yet, though polystyrene has the heat insulation effect of standing out from one's fellows, its fire-protection rating is only the B2 level, can't reach the Ministry of Public Security is the requirement of A1 level to the fire-protection rating as the skin fireproof heated board.Typically case for example: the wildfire that betides the Shanghai City Huangpu District on October 15th, 2010, this fire originates from fireproof heated board, particularly, because fireproof heated board has been used polystyrene, therefore cause the fire spreads quickly, finally cause dead and wounded tens of people's tragedy.
From the above, being decorated, skin make it possess in good energy-saving effect, should meet the requirement of aforementioned A1 level as the fire-protection rating of the fireproof heated board of external wall decorative material, and actual situation is: fire-protection rating can reach the material that the A1 level requires and often lack heat retention, and has material that the low heat retention of thermal conductivity is good polystyrene poor fire as the aforementioned.Therefore, how to utilize rational preparation method to make the skin that makes between excellent flame retardant resistance and the heat retention of standing out from one's fellows, find the problem of rational trim point to suffer from for a long time industry with fireproof heat insulation plate, and be showed no all referential technology enlightenments that has in disclosed patent and non-patent literature up to now.
For above-mentioned prior art, the applicant has carried out useful exploration, has finally formed technical scheme described below.
