Abstract
In order to reduce the energy consumption of building construction and enhance the compatibility and durability of building materials, the application of nanocapsule phase change materials in the construction of civil engineering was studied. The nanocapsule phase change material was prepared by in situ polymerization method, and the mortar with nanocapsule content of 8–23% was developed. It is applied to energy-saving building plaster walls to study the properties of nanocapsule phase change materials and their application effects in the construction of civil engineering. The experimental results show that the emulsification speed and time have certain influence on the particle size of microcapsules; the best mass ratio of core material to wall material is 1:1.4; the wall using the nanocapsule phase change material can raise the temperature by about 2.8°C compared with the ordinary wall, which can effectively reduce the thermal conductivity of the wallboard and make the wallboard have better heat storage capacity. This ensures that the indoor warmth is relatively stable and durable; after the application of nanocapsule phase change materials, the power consumption of the building’s refrigeration system is significantly lower than that of ordinary buildings, and the daily power consumption is reduced by about 16%, which saves electricity and energy consumption in the building.
