Novolac epoxy resin multifunctional radiation-resistant paint and preparation method thereof

Abstract

The invention provides a novolac epoxy resin multifunctional radiation-resistant paint. The novolac epoxy resin multifunctional radiation-resistant paint comprises the following raw materials in parts by weight: 20-30 parts of novolac epoxy resin, 10-15 parts of expanded graphite, 5-10 parts of carbon nanotube, 0.5-3 parts of hydroxypropyl methylcellulose, 8-14 parts of glass powder, 5-10 parts of talcum powder, 18-22 parts of kaolin powder, 10-15 parts of wollastonite powder, 1-5 parts of bicyclopentenyloxyethyl acrylate and 20-30 parts of water. The invention also provides a preparation method of the novolac epoxy resin multifunctional radiation-resistant paint. Various components in the novolac epoxy resin multifunctional radiation-resistant paint interact and complement each other's advantages, so that the paint has the characteristics of excellent corrosion resistance, excellent radiation resistance, excellent flame retardancy, excellent high temperature resistance, excellent crack resistance, excellent rust resistance, excellent cold-heat alternation resistance, high storage stability and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a multifunctional anti-radiation coating of phenolic epoxy resin 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 prio...

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.
