Abstract
This article synthesized the epoxy alkyd ester resin by modifying alkyd resin with epoxy resin. The characteristics of synthesized resin was considered through the thermo-oxidation resistance, the chemical resistance (in 5 wt.% HCl, or in 5 wt.% NaCl solution), the UV-thermo-humidity complex stability (30 cycles, each cycle of 8 hours in UV irradiation at 60 °C and followed by 4 hours of humidity condensation at 50 °C), and the thermal shock resistance (7 cycles, each cycle of 10 minutes in refrigerated chamber at - 50 °C and 10 minutes in oven chamber at + 50 °C) The results showed that the thermo-oxidation resistance, the chemical resistance, and the UV-thermo-humiditycomplex stability of the ester epoxy alkyd paint film were higher than that of alkyd paint film, while the thermal shock ability was similar to that of the alkyd paint.
