Tungsten tailing-based phase change heat storage aggregate and preparation method thereof

The invention provides a tungsten tailing-based phase change heat storage aggregate and a preparation method thereof, and belongs to the technical field of building functional materials, the aggregate comprises the following components: 44-66 parts of tungsten tailings, 5.5-8.0 parts of cement, 3.8-4.6 parts of gypsum, 10-21 parts of mineral powder, 6.0-12.8 parts of fly ash, 0.8-1.5 parts of lauric acid, 0.6-0.8 part of myristic acid, 0.6-1.0 part of palmitic acid, 0.6-0.8 part of n-capric acid, 0.6-0.7 part of stearic acid, and 2-3 parts of styrene-butadiene emulsion. And 2.8 to 5.4 parts of water. From the perspective of environmental protection, the tungsten tailings are easy to take and low in price. The mass of the tungsten tailings accounts for 66% of the mass of the phase change aggregate, the usage amount of cement and other cementing materials and gypsum, mineral powder, fly ash and other auxiliary cementing materials is reduced, more tungsten tailings can be consumed, and certain social value is ac
