Description

technical field [0001] The invention relates to a composite energy storage building material, in particular to a composite energy storage building material with flame retardant function. Background technique [0002] Using phase change latent heat of phase change materials to store energy is a new environmental protection and energy saving technology. During the process of phase change, the phase change material absorbs the heat of the environment and releases heat to the environment when needed, so as to achieve the purpose of controlling the temperature of the surrounding environment and saving energy. It has broad application prospects in building energy saving, solar energy utilization and other fields. [0003] The development of modern buildings to high-rise buildings requires the use of lightweight materials for the enclosure structure, but the heat capacity of ordinary lightweight materials is small, resulting in large fluctuations in indoor temperature. This not o...

Problems solved by technology

Most inorganic phase change energy storage materials are corrosive and have the disadvantages of supercooling and phase separation during the phase change process, which affects their energy storage capacity; while organic phase change energy storage materials are not only less corrosive, but There is almost no disadvantage of phase separation, and the chemical performance is stable and the price is cheap

However, organic phase change energy storage materials have the disadvantages of low thermal conductivity and flammability, resulting in poor heat transfer performance and low energy storage utilization in the application of energy storage systems, thereby reducing the efficiency of the system.
