Poly-urea microcapsules phase change materials were prepared by the interfacial polymerization using the reaction product of 2, 4-toluenediisocyanate (TDI) and tetraethylenepentamine (TEPA) as wall material. The prepared phase change materials were characterized by Fourier transmission infrared spectra (FT-IR), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). Meanwhile, the phase change materials were used into the antirust paint as thermal insulation filler;properties of the antirust paint were studied and characterized. The results show that the phase change temperature of anticorrosive coating is 19.2 ℃, and the phase change enthalpy is 65.5 J/g. Therefore, the antirust paint with poly-urea microcapsules phase change materials as thermal insulation filler has a certain temperature adjusting performance.
