The phase change coating comprises paraffin wax and montmorillonite composite phase change material, filler, adhesive, dispersant, water repellent, thickener and water, and the paraffin wax and montmorillonite composite phase change material is composed of paraffin wax and montmorillonite Composite montmorillonite. The phase change paint has the advantages of large phase change latent heat, good temperature regulation and energy storage effect, and low price. Applying the paint to the wallpaper of home decoration can not only regulate temperature and store energy, but also have the function of moisture resistance.

Description

technical field [0001] The invention belongs to the field of phase-change materials, and in particular relates to a phase-change paint and its preparation method and application. Background technique [0002] Phase change materials refer to materials that can store energy and adjust temperature by utilizing the heat absorption and heat release phenomena of certain substances during the phase change process. Phase change energy storage materials absorb and release a large amount of latent heat during the phase change process, so the temperature of the system can be kept constant at around the phase change temperature for a long time, so as to achieve temperature regulation and thermal energy storage and release, and can effectively utilize heat energy , once the material is applied, it will become the best green carrier for energy saving and environmental protection. [0003] According to the energy storage methods of phase change materials, there are three types of energy s...

Problems solved by technology

For thermal energy storage of sensible heat, the thermal energy is simply stored by increasing the temperature of solid or liquid materials. Although it is relatively simple and convenient in operation, while it is storing energy, the temperature of the material itself is also In the midst of constant changes, therefore, it is impossible to control the ambient temperature and the material device has a large volume and low energy storage density; chemical energy storage uses the reaction heat of reversible chemical reactions to store energy, and its essence is that heat energy can be stored in It is converted into chemical energy in a reversible endothermic reaction at constant temperature. Although this method has a higher energy storage density, the technology is very complicated and the operability is not strong, so the application value of these two energy storage methods is not high.
