NOVELTY - Self-heating phase change heat storage floor comprises a wear-resistant layer, an insulating waterproof layer, an upper phase change heat storage layer, a first copper film, a self-heating phase change heat storage core, a second copper film, a lower phase change heat storage layer, a supporting frame and an insulating layer, which are sequentially arranged from top to bottom. The self-heating phase change heat storage core comprises carbon-based complex phase change material. The upper phase change heat storage layer and the lower phase change heat storage layer comprises mineral- based complex phase change material. USE - Used as self-heating phase change heat storage floor. ADVANTAGE - The floor: has excellent electrical, thermal conductivity, and flame retardancy; realizes the combination of low-voltage electric heat conversion and heat storage process, and combination of thermal flame retardant and heat storage process; utilizes night low valley power to convert electric energy into heat energy for storage; releases heat to heat indoor when needed; and relieves electric peak load pressure.
