| Abstract: | Poly-urea microcapsules phase change materials were prepared by the interracial 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. |
