A heat-resistant and anticorrosive coating was prepared by using waterborne epoxy modified silicone resin,filler such as iron phosphorus powder,talc powder,mica powder and various additives,the micro morphology of the coating before and after heat resistance test was observed by SEM,the corrosion properties of the coating before and after heat resistance test were studied by electrochemical measurement system,IR was used to detect the composition changes of the coating before and after the test,The results show that,waterborne epoxy modified silicone heat-resistant and anticorrosive coating has good high-temperature corrosion resistance and can be used for a long time at 250℃.
