Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a novel environment-friendly phase change energy storage brick. Background technique: [0002] With the enhancement of people's awareness of energy saving and environmental protection, building energy saving has been paid more and more attention. Phase change energy storage building materials are phase change materials added to building materials, which can not only be used as bearing or decorative materials, but also store more heat. Energy-saving and thermal insulation walls have been popularized and applied in industrial and civil buildings. The use of fly ash to make bricks is a need for rational utilization of resources, an important way to comprehensively utilize fly ash, protect the environment, and save energy, and it is also one of the important ways to innovate wall materials. Adding phase change energy storage materials to building materials can play the role of en...
