Abstract

The invention discloses jelly-paraffin-containing phase transition energy storage perlite and self-temperature-adjustment phase transition mortar which is a new building material and is applied to self-temperature-adjustment mortar. In the phase transition energy storage perlite, expanded pitchstone and expanded perlite are taken as a carrier for a shell, phase transition paraffin is taken as an energy storage material and exists in a jelly paraffin form, and an inorganic silica-alumina compound layer coats a core. The jelly phase transition perlite is taken as a temperature-adjustment energystorage / releasing material and is mixed with cement, opal shale powder, yellow sand and water at a ratio to prepare self-temperature-adjustment phase transition mortar. Jelly paraffin technology and opal shale powder are adopted to prevent the phenomenon that liquid paraffin exudes in a solid-liquid phase transition process of phase transition paraffin and to overcome the problem that phase transition mortar is complex in preparation technology. The enthalpy value of the self-temperature-adjustment phase transition mortar is more than 500 KJ / m<2>. The mortar is of an A fireproof grade, can beapplied to building interior walls, interior walls and grounds of vegetable greenhouses and livestock pens, and can be applied to fermenting tanks and aquatic product culture.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a phase-change energy-storage perlite containing jelly paraffin and a new building material self-regulating phase-change mortar applied to self-regulating mortar. Background technique [0002] Phase change materials refer to substances that change shape with temperature and can provide latent heat. The process of phase change material changing from solid state to liquid state or from liquid state to solid state is called phase change process. At this time, the phase change material will absorb or release a large amount of latent heat. The phase change material is a new type of composite material with a core-shell structure formed by coating the surface of the particles of the solid-liquid phase change material with a stable film. During the phase change process, the phase change material as the inner core undergoes a solid-liquid phase transition, while th...
