Embodiment 1
[0065] 1) Surface modification of polystyrene particles
[0066] Bulk density 9kg / m 3 1000 liters of primary polyphenylene particles, 15kg of adhesive, 0.6kg of coupling agent, 8kg of water, and 110kg of cement; first dilute the adhesive with water, then add polyphenylene particles and silane coupling agent, stir, and wait until the surface of polyphenylene particles After being completely wetted, add cement and stir to coat the surface of the particles with a layer of cement paste.
[0067] 2) Preparation of additives for foamed cement insulation board:
[0068] 10 parts of calcium stearate;
[0069] 6 parts of Illite;
[0070] 1 part of sodium carboxymethyl cellulose;
[0071] 18 parts of calcium nitrate;
[0072] 8 parts of gypsum;
[0073] 20 parts of sodium chloride;
[0074] 19 parts of lithium carbonate;
[0075] 1 part of triethanolamine;
[0076] 6 parts quicklime;
[0077] Shrinkage reducer 3 parts.
