Abstract

The invention provides the preparation and application of a rapid film-forming energy-saving and environmental protection machine spray fine decoration mortar. The preparation method is: mixing the solid phase change material and the liquid phase change material, heating and melting, adding antioxidants and adsorption materials, and after the adsorption is saturated, Mix evenly with thermal conductivity additives and film-forming agents, solidify and form, cool to room temperature, and obtain solid-liquid phase change materials; white cement, diatomaceous earth, emulsifier, epoxidized polybutadiene, gypsum and solid-liquid phase change materials The materials are added into water, mixed evenly, cured and molded, removed from the mold, and cured for 28 days to obtain fast film-forming energy-saving and environmental protection machine spray fine decoration mortar. The refined decoration mortar prepared by the invention has high content of phase-changing materials, excellent energy storage effect, good thermal conductivity, good dispersion with mortar, good constant temperature effect, and rapid film-forming performance of epoxy-modified polybutadiene polymer Excellent, also has waterproof and anti-corrosion, therefore, the refined decoration mortar prepared by the present invention is green and constant temperature, energy-saving and durable, safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of phase-change mortar materials, and in particular relates to the preparation and application of a rapid film-forming energy-saving and environment-friendly spray finishing mortar. Background technique [0002] With the continuous development of new building materials, lightweight and high-efficiency thermal insulation materials are used more and more in building roof and wall materials. Phase change materials are substances that use the latent heat of phase change to realize heat storage, conversion and utilization. They can store a lot of heat energy in a small volume and keep the temperature basically unchanged during the heat absorption and heat release process. The indoor walls or the roof of the building maintain a relatively constant temperature, so that the room can maintain a good thermal comfort temperature. The comfortable temperature of the human body is 20-25°C, so it is necessary to add phase...
