Problems solved by technology

On the one hand, the organometallic modified graphene greatly improves the anisotropic thermal conductivity of graphene, and further improves the thermal conductivity of composite phase change materials; at the same time, the incorporation of metal alloys can also enhance the strength of phase change materials. It can reduce the problem that the introduction of phase change materials will lead to the decrease of the strength of concrete materials

preparation Embodiment 1

[0072] A mixed metal powder containing 6.538 parts of zinc powder (also containing 0.7264 parts of indium, bismuth, tin metal powder mixed in a mass ratio of 1:1:1) and 0.33 mol of ethyl chloride were dissolved in a mixed solvent of ether and tetrahydrofuran In a dry and airtight environment, the reaction was carried out, and the solvent was removed to obtain a mixture containing diethylzinc. Then 200 parts of graphene oxide was added into water and ultrasonically dispersed for 30 min. Then add the aforementioned diethylzinc-containing mixture to the dispersion, then heat to 100°C and stir for 3.5 hours. After the reaction is complete, add 20 parts of vitamin C and continue to stir and react for 2 hours at 75°C. After the reaction is completed, use Wash with toluene three times, and then dry to constant weight in a vacuum oven at 80°C to obtain a graphene mixture modified with diethylzinc.

Abstract

The invention discloses phase change concrete and a preparation method thereof. The preparation method comprises the steps that firstly, organic metal is adopted for modifying graphene, then the modified graphene is compounded with a phase change base material, and a phase change material with high heat conductivity is obtained; and then microcapsules are adopted as a packaging form of the phase change material, and the strength of the concrete material is enhanced by adding steel fibers and nano silicon dioxide, so that the phase change concrete material with good heat storage capacity and good strength performance is obtained.

Description

technical field [0001] The invention relates to building material technology, in particular to a phase-change concrete and a preparation method thereof, belonging to the technical field of building phase-change materials. Background technique [0002] In the building structure, the weight and energy consumption of the envelope structure account for more than 50% of the total weight and total energy consumption. The functional green envelope structure has important application prospects. The research and development of phase change concrete is promoting the development of green envelope structures and energy saving and consumption reduction. aspect is of great significance. Phase-change heat storage materials (PCMs) are an important class of materials for storing sensible and latent heat, which contribute to the efficient utilization and conservation of energy. Latent heat storage has a greater energy storage density than sensible heat storage, and the temperature difference...
