The invention relates to a heat-
storage energy-saving sound-insulation
building material, and the material is technically characterized by the following method which comprises the steps: mixing a certain amount of ceramsite,
perlite,
blast furnace slag,
anhydrous gypsum, an
antioxidant, anti-
cracking fibers, a thixotropic agent, a
solar energy storage material,
sodium silicate, Wacker rubber
powder, hydroxypropyl
methyl cellulose,
fly ash,
sodium citrate, urotropine, redispersible latex
powder, hydroxypropyl
methyl cellulose, 206 organic
silicon water repellent and
polypropylene fiber, performing full and uniform mixing through
cyclone separation, and after full and uniform mixing, performing packaging to obtain a finished product. When the heat-
storage energy-saving sound-insulation
building material is heated (a heat source such as
sunlight), the
building material reaches the saturation temperature and becomes a
liquid phase, and
heat energy is stored; when the external temperature is lower than the set temperature, the phase-change
heat storage material starts to release heat, the phase-change material is changed into a
solid phase from a
liquid phase after heat release is completed, and circulation is conducted in cycles. The
composite material can be made into profiles, plates,
mortar and porous bricks, can absorb sound
waves, has elasticity, generates tremble, rebound andreverse absorption under the
impact of the sound
waves, and is converted into different frequencies, so that the
structural vibration is reduced, and the purpose of
noise elimination is achieved.
