High temperature resistant radiation protection coating and preparation method thereof

Abstract

The invention provides a high-temperature-resistant radiation-proof coating, which comprises the following raw materials in parts by weight: 10-15 parts of zirconium sol, 6-10 parts of aluminum dihydrogen phosphate, 8-12 parts of expanded graphite, and 5-10 parts of carbon nanotubes , 1-5 parts of titanium dioxide, 5-10 parts of glass powder, 5-10 parts of talc powder, 20-25 parts of mica powder, 0.5-3 parts of hydroxypropyl methylcellulose, dicyclopentenyloxyethyl acrylate 1 to 5 parts and 20 to 30 parts of water. The present invention also provides a preparation method of the above-mentioned high temperature resistant radiation protection coating. The components in the above-mentioned high-temperature-resistant and radiation-resistant coating provided by the present invention cooperate with each other and complement each other, so that the coating has excellent anti-corrosion, radiation protection, antibacterial, flame-retardant, and high-temperature resistance under the premise of maintaining good adhesion. , anti-cracking, storage stability and other characteristics.

Description

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

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.
