Due to the board shape, the heat insulation board is convenient for construction and use, is reasonable in price, has the same service life with buildings, is suitable for being used by outer wall surfaces of various buildings, and has good economic benefits and social benefits.

Description

A kind ofly can block warming plate of hot cold bridge and preparation method thereof
Technical field:
The present invention relates to a kind of construction timber field, particularly relate to and a kind ofly can block warming plate of hot cold bridge and preparation method thereof.
Background technology:
Wall thermal insulating is the requisite measure of building energy-saving consumption reduction, not ideal enough for the lagging material of exterior wall at present, especially relate to energy-conservation, environmental protection, fire prevention, the fields such as insulation cannot meet various needs especially completely, the general thermal conductivity of lagging material of present majority is large, insulation, fire resistance is poor, and there is constructing operation inconvenience not easily.
The heat insulation system of buildings exterior-protected structure conventional at present. adopt polystyrene foam plate, thermal insulation mortar, hard polyurethane foam and the heat-insulating material such as glass wool, rock wool more.Name is called " high-strength fireproof plant fibre composite thermal insulative board is production method extremely ", application number is the Chinese patent application of 200410000789.7, disclose component that a kind of fire resistant heat preserving pulls and preparation method thereof, main heat-insulating material is pearlstone.The shortcoming of this prior art is: directly employ sodium silicate aqueous solution and organosilicon moisture repellent in the formula of 1, prior art, these two kinds of raw materials are all very rare aqueous solution. larger with the moisture of compound after the mix and blends such as perlite, make shaping after drying and dehydrating phase temperature require higher, time of drying is also longer, adds the cost of product.2, water glass and organosilicon moisture repellent are all the materials that alkalescence is very high; make the alkalescence of product also very high; as the skin of building heat preserving system. easily make moist the accumulation of salt in the surface soil, affects the attractive in appearance of wall face, also easily makes its outer field steel wire protection net get rusty simultaneously. and make glass fiber net aging and lose enhancement.3, sodium silicate aqueous solution is as tackiness agent, and the water tolerance after film forming is poor, easy deliquescence and infiltration. affect intensity and the weathering resistance of product.4, pearlstone is as main lagging material, because ore in sand form stone is in vaporized expanding. the spilling of crystal water makes perlite be the grain pattern of perforate, very easily pulverize and form powder, intensity is very low, product strength is reduced, and easily absorbing steam again, after the moisture absorption, the heat-insulating property of product greatly reduces.In the whipping process of 5, preparing product, due to perlite very easily crushing-type powdered. churning time can not be long, but churning time is too short. cause again glue can not fully mix with perlite, have a considerable amount of perlite surface to fail fully to be wrapped up by glue, thus affect the intensity of product, easily damaged and fracture.6, surface adhesion layer of glass net is pulled in insulation, and one side glass fiber net can not ensure that product does not occur fracture distress completely, because cause the external force of fracture to be uncertain.
Summary of the invention:
Goal of the invention: in order to provide a kind of efficient, energy-conservation, fireproof heated board, it has environmental protection and is incubated significantly and flameproof effect.
In order to reach as above object, the present invention takes following technical scheme: its raw material weight proportioning portion rate is as follows: cement 40-45 part; Dispersible rubber powder 8-35 part; Cellulosic fibre 0.1-0.5 part; Granular polystyrene 10-15 part; Flyash 20-25 part; Froth breaking stone 5-10 part, fine particle calcium carbonate 1-5 part; Coarse whiting 1-5 part; Lagging material 10-15 part; Expanded and vitrified small ball 20-50 part.
The further technical scheme of the present invention is: described cellulosic fibre is lignocellulose or aluminum silicate fiber.
The further technical scheme of the present invention is: described cement is 525 slag cement.
The further technical scheme of the present invention is: described raw material is carried out three clothes, once shaped.
The further technical scheme of the present invention is: at described shaping sheet material appearance spray coating heat preservation coating.
The further technical scheme of the present invention is: thermal insulation coatings comprises organic silicon emulsion 35%; Heat reflection cenosphere 16%, titanium dioxide 10%, hollow calcium carbonate 7%, brucite 6%, pyrophyllite 5%; Expanded and vitrified small ball 4%, water 17%.
Adopt warming plate prepared by the arbitrary described preparation method of technical scheme.There is following beneficial effect: the product made in this way has good heat insulation effect: A level is prevented fires, and not high to body of wall fundamental importance, thermal insulation layer is firm, there will not be full of cracks, hollowing, come off and/or crack, executive cost is cheap, good decorating effect, non-environmental-pollution, with the building same life-span, can use by spread, be a kind of toxicological harmless, pollution-free, the finishing material of environmental protection, is applicable to external wall Surgery therapy, roof heat insulation.Due to three clothes, heat bridge cold bridge can also be blocked, because its surface spraying has thermal insulation coatings, make its heat-insulating property and hydrophobicity performance more be better than traditional lagging material, due in sheet material shape, traditional construction difficult problem and a transport difficult problem can be solved!
In a word, the present invention has good flame retardant properties, does not burn, and heat-insulating property is good, and cohesiveness is good, and intensity is high, and construction usage is convenient, reasonable price, with the building same life-span, is applicable to various external wall metope and uses, have good economic benefit and social benefit.
