The preparation method of lightweight inorganic fireproof heat preservation plate material, comprises the following steps:
(1) preparation of the aqueous solution of whipping agent
Weigh each component raw material by formula rate, load weighted palmityl trimethyl ammonium chloride is dissolved in the water and is stirred, leave standstill 10min, then regulate pH value to 3-4 with concentrated hydrochloric acid, leave standstill again after 11min, add Polyethylene Octylphenol Ether-10, continue to leave standstill 11min after stirring 8-10min; 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 having left standstill into air compressor machine, keep pressure 0.2Mpa, just can send foam, the foam sending need to leave standstill 30-35min, to density be 35 ± 5kg/m
3, stand-by;
(3) stirring of slurry
Requirement, be in 0.46:1 situation at fixing water and gelling material mass ratio, 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 the foam that adds step (2) to leave standstill by formula rate, fully stirs and makes even fluidised form foam slip, and concrete operations are as follows:
A, according to the proportioning of 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, keep identical speed to stir again 15s, and then with the speed rapid stirring 55s of 115r/min, slurry is fully disperseed, obtain grout;
B, foam step (2) having been left standstill by formula rate join in the grout having stirred, and in the process adding, keeping stirrer rotating speed is 44r/min, until that foam adds is complete, this process approximately maintains 29s;
C, after all material adds, then low rate mixing 4-5min, makes even fluidised form foam slip;
(4) plate forming
It is moulding in 100mm × 100mm × 100mm or 600mm × 300mm × 50mm forming mould that the foam slip that step (3) is made is poured into specification, be positioned over maintenance in cement standard maintaining box, curing temperature is 20 ℃, maintenance relative humidity is 90-95%, curing in the mold 24h, and then demoulding maintenance is to testing after the length of time, test respectively its apparent density, ultimate compression strength, water-intake rate and thermal conductivity performance.
The described polycarboxylic acid water reducing agent of step (3) is that the patent No. is the polycarboxylic acid water reducing agent that 201010515271.2 method makes.
The Performance Detection of lightweight inorganic fireproof heat preservation plate material prepared by the inventive method is as following table 1:
The full the performance test results of table 1 lightweight inorganic fireproof heat preservation plate material
| Sequence number | Interventions Requested | Assay |
| 1 | Dry density, kg/m 3 | 280 |
| 2 | Thermal conductivity (25 ℃), W/ (mK) | 0.06 |
| 3 | Ultimate compression strength, MPa | 0.6 |
| 4 | Tensile strength, MPa | 0.15 |
| 5 | Water-intake rate, % | 6 |
| 6 | Drying shrinkage value, mm/m | 0.60 |
| 7 | Coefficient of softening | 0.85 |
| 8 | Carbonation coefficient | 0.95 |
