Abstract

The invention relates to a coating, in particular to an anti-corrosion and anti-radiation coating for nuclear power. The anti-corrosion and anti-radiation coating is characterized by comprising the following raw materials in parts by weight: 10-15 parts of titanium dioxide, 7-9 parts of calcium carbonate, 6-8 parts of potassium titanate crystals, 3-5 parts of talcum powder, 3-4 parts of carbon nano tubes, 12-14 parts of kaolin powder, 1-5 parts of expanded graphite, 7-9 parts of glass powder, 0.5-1.5 parts of hydroxypropyl methyl cellulose, 2-4 parts of triethanolamine, 11-14 parts of wollastonite powder and 15-35 parts of water. The coating has excellent characteristics of corrosion resistance, radiation resistance, high-temperature tolerance, crack prevention, cold-hot alternation resistance, storage stability and the like on the premise that good adhesion force is kept.

Description

technical field [0001] The invention relates to a coating, in particular to an anti-corrosion and anti-radiation coating for nuclear power. Background technique [0002] The hazards of nuclear radiation are well known, so the internal and external surfaces of nuclear reactors, nuclear power plants, isotope laboratories and other buildings, devices and equipment that are prone to radioactive contamination need to be protected to reduce the hazards of nuclear radiation. The main protective measures are through Apply paint. At present, the vast majority of nuclear radiation coatings used in the market are solvent-based. During production and construction, the volatilization of solvents not only causes waste of non-renewable petroleum resources, but also pollutes the environment. Therefore, it is of great practical significance to develop environmentally friendly nuclear radiation-resistant coatings. Contents of the invention [0003] In order to overcome the existing above-...
