Description

Insulated fire decoration integrated board of the low unit weight of high strength and preparation method thereof
Technical field
The invention belongs to building slab field, relate to particularly a kind of insulation, fire prevention, decoration integrated board with high strength, low unit weight.
Background technology
The arrival of 21 century, under the guide of the Scientific Outlook on Development, construction field is clear and definite must walk resource-conserving, environmentally friendly new road toward industrialization.For building energy conservation, the link of most critical is exactly the reduction of energy consumption in the use popularization of novel high-efficiency and energy-saving heat preserving and insulating material and work progress.The focus that emerging insulation and decoration integrated plate has become building trade to pay close attention to.
This insulation and decoration integrated plate is (or the polyurethane batch (-type) foaming positive and negative of the heat insulating materials such as extruded sheet, benzene plate, polyurethane sheet is combined with each other the materials such as reason slabstone, calcium silicate board by two component glues in the mode of colding pressing after, foaming front pressuring plate mode is compound), then liquid state is managed to the coating such as stone, true stone, fluorine carbon as decorative layer.Insulation that what this type systematic was relatively traditional finish is done the method for decorating again and is saved Jin Shi road working procedure, and has avoided the inhomogeneities of the artificial high-altitude application of coating, has greatly shortened construction period and has reduced construction cost.
But current this insulation and decoration integrated plate exists following shortcoming: first, fireproof performance is poor, integrated board surrounding, without fireproof jointing sheath, can not stop the intensity of a fire laterally to spread.Secondly, integral slab unit weight is high, and when general insulation layer 50mm thickness, integrated board finished product unit weight, up to 12-15kg/ ㎡, is unfavorable for easily coming off after construction and upper wall.Again, suppleness is low, and compound calcium silicate board rigidity is strong, impacts frangible.
And the coefficient of thermal conductivity of the superior heat insulating material such as foam cement, foamed glass of fireproof performance is all far beyond more than 0.05, even reaches more than 0.1.This and heat insulating material focus on to be emphasized not energy-conservationly to be inconsistent, and is difficult to popularize in an all-round way as high-performance energy-saving heat-insulating material.Have the rock wool heat-preservation material of fire prevention and insulation advantage concurrently, also, all the time because expensive price, occur that compared with the short period rock wool sinks, cause top fatal harm hollow and that constructor is inhaled to lung, be difficult to apply widely.Extensive all the more along with insulation and decoration integrated plate application, original mentality of designing and product structure obviously can not meet the needs of current building heat preservation industry.
Summary of the invention
