The third generation of nuclear power technology put forward more oppressive requirements on nuclear power coating.A series of abilities,mainly including simulated DBA test,radiation resistance and decontamination performance,were needed.In this work,we used MDI and HDI compounds as curing agent,Mica powder,talcum powder,potassium titanate such as functional filler and other additives to achieve a radiation-resistant epoxyurethane coating.The results showed that this coating can tolerate 10^7 Gy irradiation,pass the simulated DBA test and had good decontamination ability,especially had favourable impact-resistance and mechanical properties.
