Surface-modified tetradecane phase change microcapsule, temperature-control anti-freezing concrete and preparation method of surface-modified tetradecane phase change microcapsule
According to the surface modified tetradecane phase change microcapsule, the surface modified tetradecane phase change microcapsule is a nano SiO2 surface modified tetradecane phase change microcapsule, a phase change material is tetradecane, and a supporting material (poly (n-butyl methacrylate)) is used as a packaging shell of the phase change microcapsule. The invention relates to temperature-control anti-freezing concrete. Nano SiO2 surface modified tetradecane phase change microcapsules are used as a temperature-control heat storage material. According to the nano SiO2 surface modified tetradecane phase change microcapsule prepared by the preparation method disclosed by the invention, the interface performance of the microcapsule and a cement-based material is modified and improved by utilizing a nucleation effect and a pozzolanic effect of SiO2 in a hydration process of the cement-based material; the temperature-control anti-freezing concrete material based on phase change heat storage has good mechanical performance and excellent anti-freezing and thawing performance, and can effectively improve the durability of supporting structure concrete in the construction and use process of tunnels in cold regions.
