High-temperature-resistant anti-corrosion and anti-radiation coating and preparation method thereof

Abstract

The invention provides a high-temperature-resistant anti-corrosion and anti-radiation coating. The coating comprises the following raw materials in parts by weight: 8-12 parts of aluminum sol, 10-15 parts of expanded graphite, 5-10 parts of carbon nano tube, 1-5 parts of titanium dioxide, 0.5-3 parts of hydroxypropyl methyl cellulose, 8-14 parts of glass powder, 5-10 parts of talcum powder, 20-25 parts of mica powder, 1-5 parts of methacrylic acid dicyclopentenyl-oxy-ethyl ester and 20-30 parts of water. The invention further provides a preparation method of the high-temperature-resistant anti-corrosion and anti-radiation coating. The components in the coating are mutually matched to complement the advantages each other, so that the coating has the properties of excellent corrosion resistance, radiation corrosion resistance, antibacterial property, flame retardance, high temperature resistance, cracking resistance, storage stability and the like on the premise that the adhesive force is remained.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a high-temperature-resistant, anti-corrosion, radiation-proof 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...

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.
