Abstract

The invention relates to an environment-friendly anti-radiation coating and the preparation method thereof. Melamine formaldehyde resin and modified fluorine-containing resin are used as film formingsubstances, filler is added to prepare a coating product, water is used as a solvent, and the environment-friendly anti-radiation coating is environmentally friendly, good in film forming compactnessand capable of effectively preventing radon in a wall and a stratum from escaping into air; the filler takes carbon nanotubes as a raw material and is prepared through vanadium and molybdenum doping,hexamethylene diisocyanate modification and a polyacrylic acid ammonia esterification reaction. The coating has good compatibility and dispersibility in a system, is beneficial to increase of the specific surface area of a coating film, has a good adsorption effect on radon in air, reduces the content of radon in indoor air, has excellent radon radiation resistance, is green and environment-friendly, and has extremely good popularization significance.

Description

technical field [0001] The invention belongs to the technical field of paint processing, and relates to an environment-friendly anti-radiation paint and a preparation method thereof. Background technique [0002] Radon widely exists in people's living environment, especially the radon released from indoor building materials and house foundation soil is very easy to accumulate indoors, resulting in a high content of indoor radon, which brings great safety hazards to people. Radon is the only gaseous radioactive element that humans come into contact with. It is a chemically inert elemental inert gas that is colorless, odorless, and tasteless. It is difficult to chemically react with other elements, but it will decay after being inhaled into the human body. The generation of alpha particles can cause radiation damage to the respiratory system and cause lung cancer, which is the second largest cause of lung cancer after smoking. According to the International Cancer Research Ce...
