Multi-functional coating and preparation method thereof

Abstract

The invention relates to a multi-functional coating and a preparation method thereof; the mass percentage of the raw material composition of the multi-functional coating is that: 1 percent to 5 percents of nano bamboo charcoal, 1 percent to 5 percents of nano boron carbide, 1 percent to 5 percents of compatilizer, and the rest is a base material; the preparation method comprises the steps that: the nano bamboo charcoal and the nano boron carbide are dissolved in the compatilizer ethanol and are continuously stirred until being fully dissolved, and a functional material is obtained; and the functional material is mixed with the base material, and a final product, i.e. the multi-functional coating is obtained. The multi-functional coating provided by the invention contains nano boron carbide, has a larger thermal neutron capture cross section and very good neutron absorption and anti-radiation performance, contains nano bamboo charcoal, and has absorption and environmental purification functions.

Description

【Technical field】 [0001] The invention relates to the technical field of coatings, in particular to a multifunctional 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 Fukushima earthquake in Japan 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 It 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. [0003] At p...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the anti-radiation coatings are used to add heavy metal or rare metal powder and its oxides to the coating components, especially metal compounds containing Ba, Pb, U, Lu, etc., or to use composite coatings, but it will inevitably bring construction problems. Difficulty, insufficient adhesion, and insufficient functions. Therefore, the application field of radiation protection coatings is only in some special industries and special fields, and there are few applications in people's lives and other fields. Therefore, while developing radiation protection properties, It also has other additional properties, which meet the basic functions of coatings and broaden its application fields, and also meet the requirements of multi-functional and multi-field development of coatings.
