Description
Technical field
The present invention relates to building materials technology field, more particularly, to a kind of fire-type foam cement injection polyurethane complex heat-preservation
Plate.
Background technology
Building Energy Conservation Policy and the enforcement of Building Fire Protection specification, have promoted the fast development of wall heat insulation material.Polyurethane
The organic insulation materials such as rigid foam plate, polystyrol plastic foam plate, phenolic foam plate, because of its insulation
Excellent performance has obtained relatively broad application in building heat preservation engineering.The fatal weakness of polyurethane foam is exactly flammability
Can, easily it is ignited, and combustion process release harmful gass.Even if with the addition of fire retardant also cannot fundamentally change this genus
Property, the highest burning rank of polyurethane foam board for building also can only accomplish b1 level.Cement insulation board, expanded perlite
The inorganic heat insulation materials such as warming plate, inorganic material parcel polyphenylene granule heat-insulating plate, can reach a level of classification system for fire performance not
Combustible material standard requires, and has also obtained more universal application in building field, but has because its thermal and insulating performance is less than
Machine insulation material, heat conductivity is 1.5-2 times of organic insulation material, and density is big, from great, with China's building energy conservation requirement
Step up, tend not to meet Current Building ' energy saving igniter requirement.Research and development are adapted to Current Building ' energy-saving design mark
The building thermal insulation material of alignment request and fire safety rules has become current study hotspot.
In " preparation of foam cement/injection composite insulation boards and performance study " literary composition, using cement insulation board as
One side template, injection foaming polyurethane material organic insulation material in a mold, heated, extrusion forming, formed after the demoulding and send out
Soaked mud/injection composite insulation boards, cement insulation board is located at the outside of foam cement/injection composite insulation boards, flammability
A1 level can be reached, when meeting fiery heat, heat is concentrated mainly on this, does not have too many heat and enters into polyurethane insulation coating, energy
Enough play fireproof effect.The composite insulation boards made have good fire protecting performance, and thickness is little, composite plate global density
Low, reduce the energy consumption in production process, environmental protection and energy saving；But because foam cement layer is located at the outside of warming plate, light weight is many
The feature in hole makes it have higher water absorption, and moisture content is higher, and heat insulating ability is poorer, and intensity is also lower, which limits compound
The application of warming plate, needs this is modified.
Content of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of fire-type foam cement injection polyurethane
Composite insulation boards.
The present invention is achieved by the following technical solutions:
A kind of fire-type foam cement injection polyurethane composite insulation boards, are made up of the raw material of following weight portion: waste and old cotton
Flaxen fiber 3-4, chlorinated paraffin 1-1.2, fatty alcohol-polyoxyethylene ether 0.3-0.34, superelevation thin portland cement 45-50, concentration are
30wt% hydrogen peroxide 3.5-4, Gypsum Fibrosum powder 3-3.5, stearic acid 2-3, aluminum sulfate 2.5-3, organosilicon breast 1.6-1.8, deionized water are fitted
Amount, polyoxypropylene polyol 75-80, isocyanates 23-25, pentamethyldiethylenetriamine 2.2-2.4, pentane 10-12, two
Methyl-silicone oil 1.5-2, high ammonium polyphosphate 8-10, expansible graphite 13-15, polyvinyl alcohol 0.4-0.5, concentration are the boric acid of 5wt%
Aqueous solution 35-37.
A kind of described fire-type foam cement injection polyurethane composite insulation boards, are made up of step in detail below:
(1) remove impurity in discarded cotton fibriia, and it is stand-by to be cut into the chopped fiber of 10 millimeter；By chlorinated paraffin in 90-100
DEG C oil bath in heat 1-1.5 hour, be subsequently adding fatty alcohol-polyoxyethylene ether, after stirring 30-40 minute, add total amount 3-4
The deionized water of times amount, is mixed with above-mentioned chopped fiber after being subsequently cooled to room temperature, dispersed with stirring uniformly rear centrifugation, is dried,
Obtain water-repellent modified reinforcing fiber；
(2) organic silicon emulsion is mixed homogeneously with the deionized water of 25-28 times amount, be subsequently adding the thin portland cement of superelevation, stone
Cream powder, adds stearic acid, aluminum sulfate after the stirring 60-90 second, adds concentration to be 30wt% hydrogen peroxide, soon after continuing the stirring 60-90 second
