Environment-friendly anti-radiation coating and preparation method thereof

Abstract

The invention provides an environment-friendly anti-radiation coating .The environment-friendly anti-radiation coating is prepared from, by weight, 20-30 parts of novolac epoxy, 10-20 parts of expanded graphite, 5-10 parts of carbon nano tubes, 1-5 parts of titanium dioxide, 5-10 parts of glass powder, 5-10 parts of talcum powder, 10-15 parts of kaolin powder, 10-15 parts of wollastonite powder, 0.5-3 parts of hydroxypropyl methyl cellulose, 1-5 parts of acrylic acid bicyclo-pentenyl oxy-ethyl ester and 20-30 parts of water .The invention further provides a preparation method of the environment-friendly anti-radiation coating .All the components in the environment-friendly anti-radiation coating are matched and make respective advantages complementary to one another, and on the premise that good adhesive force is kept, the coating has the advantages of excellent corrosion prevention, radiation protection, bacterium resistance, flame retardance, high temperature resistance, fracturing resistance, corrosion resistance, cold and hot alternation resistance, storage stability and the like .

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an environment-friendly anti-radiation 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...

AI Technical Summary

Problems solved by technology

[0003] 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 inevitably bring construction problems. Difficulty, insufficient adhesion, and insufficient functions. Therefore, anti-radiation coatings are only used in some special industries and special fields, and are rarely used in people's lives and other fields.
