The invention refers to the field of construction area, particularly to inner wall plastering materials, that is classified as dry-mix. It contains microencapsulated phase change material and hollow microcapsules, which are treated with chemical admixture, before mixing with other components of dry-mix. Chemical admix provides equal dispersion of microencapsulated phase change materials and hollow microcapsules in the volume of plaster after adding of water (18 % - 20 %) and prevents creation of agglomerates from microcapsules as well as increases adhesion between microcapsules and hydrated cement paste. Such plaster has thermo-regulation and heat-insulation quality and has decorative surface. It could be spread simple and easy on several layers on the vertical and horizontal surfaces. Microencapsulated phase change material by changing the phase from solid to liquid and vice versa absorbs and releases definite amount of heat energy accordingly the thickness of plaster: 2.5 cm thick layer of plaster can absorb and release 180-200 kJ/m2, and 1.5 cm thick can 110-130 kJ/m2. |
