Problems solved by technology

[0005] Simply adding boron nitride into the paint has poor dispersion effect, and the bonding between boron nitride particles is not tight enough, the effect of radiation protection is not good enough, the cost of boron nitride is high, and the large amount of boron nitride will greatly increase the cost of paint. It is necessary to find a better one. Decentralized method to improve radiation protection effect and reduce cost

Embodiment Construction

[0020] A method for preparing radiation-proof thermal insulation coating, the steps are

[0021] (1) Disperse nano-barium titanate in a solvent to make a dispersion, and then evenly disperse it in a cohesive resin, stir to form A slurry, the mass percentage of nano-barium titanate is 28%;

[0022] (2) Disperse the boron nitride nanosheets in a solvent to make a dispersion, and then uniformly disperse it into a cohesive resin, stir to form a B slurry, and the mass percentage of the boron nitride nanosheets is 5%;

[0023] (3) Feed the two slurries A and B into the extruder to form a film through two-layer co-extrusion;

[0024] (4) The adhesive film is cured, ground, and crushed to a particle size of 480 microns to obtain a powder;

[0025] (5) Mix the powder and the binder uniformly to obtain.

[0026] The solvent is ethyl formate.

[0027] The adhesive resin is one or a mixture of polyvinyl butyral, epoxy resin, acrylic resin, EVA resin, polyester resin, alkyd resin, and polyurethane res...

Abstract

The invention provides a preparation method of an anti-radiation heat insulation coating. According to the method, bi-layer thin film micro-sheets are prepared from nano-barium titanate and boron nitride nano-sheets, the nano-barium titanate and the boron nitride nano-sheets are arranged in the coating in an orientated manner as the proportion of the nano-barium titanate to the boron nitride nano-sheets is different, radiation resistance, water resistance, corrosion resistance and abrasion resistance are improved, the surface of the coating is bright and clean, not easily stained, easily cleaned and high-end. A sheet nano-barium titanate structure with the size can reflect thermal infrared rays ranging from 5 micrometers to 25 micrometers, and the heat insulation performance of the coating is improved.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of radiation-proof and heat-insulating coatings. Background technique [0002] At present, the application of nuclear technology has penetrated into various fields of the national economy and has become an indispensable part of modern society. At the same time, various high-energy rays (such as X-rays, gamma rays, neutron rays, etc.) produced by nuclear radiation have not only caused a new environmental pollution (nuclear pollution), but also seriously endangered human health. Therefore, reasonable control and The protection of nuclear radiation has become an urgent problem to be solved. Because neutron rays have the characteristics of large energy and strong penetrating ability, its protection is particularly important. The application of nuclear radiation protection coatings has received great attention. It is mainly used for the protection of the internal an...
