Problems solved by technology

However, the solvents of the coatings all use non-environmentally friendly solvents such as xylene or butanol
After the coating is finished or used for a long time, there will be solvent precipitation, and the solvent will seriously pollute the marine environment around the nuclear power plant

preparation example Construction

[0034] The preparation method of steel structure anti-nuclear radiation coating of the present invention mainly comprises the following steps:

[0035] a: Weigh epoxy resin, silicone-modified epoxy resin, radiation-resistant filler, diluent, processing aid, curing agent and coupling agent according to the above ratio for later use;

[0036] b: Put epoxy resin, silicone modified epoxy resin, diluent and processing aid in the paint mixing tank, and stir for 2-5 hours at normal temperature and pressure;

[0037] c: Add radiation-resistant fillers to the mixture in step b, and stir for 3-6 hours at normal temperature and pressure until they are evenly mixed;

[0038] d: Grind the mixture in step c through a three-roller machine at normal temperature and pressure until it becomes granular, and the particle size is 20-50 μm;

[0039] e: Add a curing agent to the mixture in step d, and stir for 1-4 hours at normal temperature and pressure;

[0040] f: Add coupling agent to the mixt...

Abstract

The invention discloses a steel-structure-use nuclear-radiation-resistant paint which is characterized in that the paint comprises main agents, a curing agent, and a coupling agent. The main agents comprise epoxy resin, organosilicon modified epoxy resin, a radiation-resistant filling agent, a diluting agent, and a processing auxiliary agent. The paint is prepared from the components of, by mass: 100 parts of epoxy resin, 20-60 parts of organosilicon modified epoxy resin, 50-80 parts of radiation-resistant filling agent, 30-60 parts of the diluting agent, 2-5 parts of the processing auxiliary agent, 25-50 parts of the curing agent, and 1-3 parts of the coupling agent. A mass percentage ratio of the main agents to the curing agent is 6-11:1. The steel-structure-use nuclear-radiation-resistant paint provided by the invention has excellent radiation resistance and decontamination property. The paint does not precipitate environment-polluting harmful substances.

Description

technical field [0001] The invention relates to a nuclear radiation-resistant paint and a preparation method thereof, in particular to a nuclear radiation-resistant paint for steel structures and a preparation method thereof. Background technique [0002] As a clean, safe and sustainable energy source, nuclear power has gradually attracted the attention of countries all over the world, and its development speed and popularity are also increasing year by year. Nuclear power plants are usually built in coastal areas rich in water resources. Due to the corrosive marine atmospheric environment, the buildings and equipment in nuclear power plants are easily corroded by the atmospheric environment and appear aging phenomena. At the same time, nuclear radiation also exists in nuclear power plants, which will accelerate the aging of buildings and equipment, and the surfaces of buildings and equipment will also absorb radioactive dust to form radioactive sources, affecting the health...
