Energy storage building material and preparation method thereof

Abstract

The invention discloses an energy storage building material and a preparation method thereof. The energy storage building material is prepared by mixing a mixture of polyethylene glycol and cement and expanded graphite, wherein the mass ratio of the polyethylene glycol to the cement is 1:1-10, and the expanded graphite is 1 to 10 percent of the mass concentration of the mixture of the polyethylene glycol and cement. The preparation method comprises the following steps of: mixing the polyethylene glycol with the molecular weight of 1,000 and the cement in the mass ratio of 1:1-10 to form the mixture of the polyethylene glycol and the cement, heating the polyethylene glycol in the mixture into a completely molten state, and uniformly stirring with the cement to form an uniform mixture; and adding the expanded graphite with the mass concentration of 1 to 10 percent into the uniform mixture, and continuously stirring uniformly to obtain the energy storage building material. By compounding wall materials and the energy storage building material, the temperature regulation capacity of the buildings can be enhanced, and the energy-saving and comfortable effects can be achieved.

Description

technical field [0001] The invention relates to a building material, in particular to an energy storage building material and a preparation method thereof. Background technique [0002] Energy saving and environmental protection are the most important issues in the field of energy utilization. Using phase change latent heat of phase change materials to store energy is a new environmental protection and energy saving technology. During the process of phase change, the phase change material absorbs the heat of the environment and releases heat to the environment when needed, so as to achieve the purpose of controlling the temperature of the surrounding environment and saving energy. It has broad application prospects in building energy saving, solar energy utilization, refrigeration and air conditioning, heat recovery and other fields. [0003] The development of modern buildings to high-rise buildings requires the use of lightweight materials for the enclosure structure, but...
