Abstract

The invention belongs to the technical field of building function materials, and discloses energy-saving composite phase-change energy storage interior thermal insulation mortar of heliogreenhouse wall and a preparation method thereof. The thermal insulation mortar is the mixture prepared from raw material dry powder and water which accounts for 70%-110% of the total weight of the raw material dry powder, and the raw material dry powder takes building flue gas desulfurization gypsum as a cementing material and is prepared from light composite shape-stabled phase change particles, redispersible powder, citric acid, hydroxypropyl methyl cellulose ether, polypropylene fiber and the like. The composite phase-change energy storage interior thermal insulation mortar is used for heat preservation inside the heliogreenhouse wall, the effects of better heat preservation and heat storage and heat release can be achieved, the thermal environment inside a heliogreenhouse is improved, and the growth efficiency of crops in a greenhouse can be improved, thereby g the production benefits of the greenhouse is improved.

Description

technical field [0001] The invention belongs to the technical field of building functional materials, and relates to a phase-change energy storage internal thermal insulation mortar, in particular to an energy-saving solar greenhouse wall composite phase-change energy storage internal thermal insulation mortar and a preparation method thereof. Background technique [0002] The wall of a solar greenhouse is the main carrier for the greenhouse to absorb / storage solar energy. The more solar energy the wall accumulates during the day, the more heat it can supply to the greenhouse at night. Wall materials are particularly important for improving the ability to control the thermal environment in the greenhouse. . Traditional wall materials usually include simple earth walls, clay brick walls, composite walls, etc., whose thermal performance is mainly thermal resistance, usually by increasing the thickness to achieve a better heat preservation and heat storage effect, which causes ...
