Abstract
The invention belongs to building material technical fields, and in particular to a kind of sulphate aluminium cement assembled integrated interior wall and preparation method thereof.Sulphate aluminium cement assembled integrated interior wall provided by the invention is using sulphate aluminium cement as primary raw material, have the characteristics that hydration and hardening rate is fast, early strong, have the advantages that low alkalinity, stabilization is fast, drying shrinkage expansion rate is small again, it is used to prepare porous foam thermal insulation material, the rapid condensation cure of foam generated can be made to form pore structure in cementitious material, be conducive to improve the stability of foam and the performance of product.Embodiment the result shows that, in above-mentioned sulphate aluminium cement assembled integrated interior wall the thermal coefficient of insulation board be 0.033~0.035W/ (mk), compression strength reaches 0.7~1.0MPa, meets the performance requirement of assembled integrated interior wall.
