Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a radiation-proof novolac epoxy resin coating and a preparation method thereof. Background technique [0002] Anti-radiation materials have become a major topic in materials science today. With the emergence and wide application of various high-radiation equipment, the research on anti-radiation materials has attracted widespread attention. The Fukushima nuclear power plant crisis triggered by the Japanese earthquake on March 11, 2011 also aroused people's concerns about nuclear radiation; the existence of various radiation sources in people's lives also forces people to pay attention to radiation-proof materials; radiation has Listed by the World Health Organization as the fourth largest source of environmental pollution after water, air, and noise, it has become an invisible "killer" that endangers human health, and radiation protection has become a top priority. [0003] At ...
