The preparation method of lightweight inorganic fireproof heat preservation plate material, comprises the following steps:
(1) preparation of the aqueous solution of whipping agent
Each component raw material has been weighed by formula rate, load weighted palmityl trimethyl ammonium chloride is dissolved in the water and stirs, leave standstill 10min, then regulate pH value to 3-4 with concentrated hydrochloric acid, after leaving standstill 11min again, add Polyethylene Octylphenol Ether-10, after continuing to stir 8-10min, leave standstill 11min; Finally add sodium lauryl sulphate, stir 11min and just prepare the aqueous solution of whipping agent, allow its standing 2.5h, stand-by;
(2) preparation of wet foam
Pour the aqueous solution of the whipping agent left standstill into air compressor machine, keep pressure 0.2Mpa, just can send foam, the foam sent needs standing 30-35min, is 35 ± 5kg/m to density
3, stand-by;
(3) stirring of slurry
Requirement, under fixing water and gelling material mass ratio are 0.46:1 situation, add polycarboxylic acid water reducing agent, water reducer volume is the 0.5-0.8% of gelling material, prepare the cement paste that degree of mobilization is 280mm, then add by formula rate the foam that step (2) left standstill, fully stir and make even fluidised form foam slurry, concrete operations are as follows:
A, proportioning according to above-mentioned requirements, water is added in agitator kettle, add water reducer and gelling material, then with the speed low rate mixing 28s of 43r/min, when speed is brought up to 50r/min, add composite blend, after adulterant all adds, identical speed is kept to stir 15s again, and then with the speed rapid stirring 55s of 115r/min, slurry is fully disperseed, obtains grout;
B, by formula rate, the foam that step (2) has left standstill is joined in the grout stirred, in the process added, keep stirrer rotating speed to be 44r/min, until foam adds complete, this process about maintains 29s;
C, after all material adds, then low rate mixing 4-5min, namely makes even fluidised form foam slurry;
(4) plate forming
It is shaping in 100mm × 100mm × 100mm or 600mm × 300mm × 50mm forming mould that the foam slurry that step (3) is obtained is poured into specification, be positioned over maintenance in cement standard maintaining box, curing temperature is 20 DEG C, maintenance relative humidity is 90-95%, curing in the mold 24h, after then demoulding maintenance extremely tests the length of time, test its apparent density respectively, ultimate compression strength, water-intake rate and thermal conductivity performance.
Polycarboxylic acid water reducing agent described in step (3) to be the patent No. be 201010515271.2 the obtained polycarboxylic acid water reducing agent of method.
The Performance Detection of lightweight inorganic fireproof heat preservation plate material prepared by the inventive method is as following table 1:
