Problems solved by technology

[0010] The above-mentioned anti-radiation coating is composed of anti-radiation filler and film-forming base material. Its anti-radiation performance mainly depends on the composition of anti-radiation filler. Most of the film-forming base material is epoxy resin, but the anti-radiation performance cannot meet the strict requirements of nuclear power plants.
At present, the research on the radiation protection performance of film-forming base materials is still blank. Therefore, it is extremely important to develop a full-system, multi-functional radiation protection coating.

Description

technical field [0001] The invention relates to a radiation-proof water-based paint, in particular to a PEEK modified polyurethane anti-corrosion and radiation-proof water-based paint for steel structures, and belongs to the technical field of water-based functional paints. 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. Radiation has been listed by the World Health Organization as the fourth largest source of environmental pollution after water, air, and noise, and has become an invisible "killer" that endangers human health. Radiation protection has become a top priority. At present, most anti-radiation coatings use heavy metal or rare metal powder and their oxides, especially metal compounds containing Ba, Pb, U, Lu, etc., or composite coatings, but it will ine...
