Abstract

The invention discloses an energy-storage heat-preserving building material in the field of building materials. The energy-storage heat-preserving building material comprises the following components: 300 to 380 parts of cement, 80 to 140 parts of coal ash, 3 to 5.5 parts of a plasticizer, 4 to 6 parts of a water reducing agent, 2 to 4 parts of polypropylene fibers, 8 to 11 parts of expanded polyphenyl granules, 55 to 65 parts of paraffin and 16 to 20 parts of expanded perlite. The energy-storage heat-preserving building material has the beneficial effects that as the paraffin exists in pores of the expanded perlite, the surface tension of the pores is relatively large, and the phase-changing energy-storage heat-preserving building material is still good in stability after working for a long time, so that the phase-changing energy-storage heat-preserving building material is good in thermoregulation effect and energy-saving effect and good in application prospect in the field of building energy-saving materials.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an energy storage and thermal insulation building material. Background technique [0002] The application of phase change energy storage materials in building wall panels can reduce the temperature fluctuation caused by the ambient temperature to the room, improve the comfort of the room, and at the same time reduce building energy consumption and play a role in energy saving. Therefore, many researchers are committed to finding and studying phase change energy storage materials with high phase change latent heat and stable performance. At present, the commonly used phase change energy storage materials mainly include inorganic substances and organic substances. Inorganic phase change energy storage materials are generally corrosive, and the phase change process has the disadvantages of supercooling and phase separation, which affect their energy storage capacit...
