Embodiment 1-3

[0021] The preparation method of embodiment 1-3 is as follows:

[0022] (1) Pump the water-based epoxy modified polyurethane resin (PUD) into the batching kettle for stirring, the temperature in the kettle rises to 55-60°C, and keep it under stirring for 5 minutes;

[0023] (2) Open the pure water tank and the propylene glycol methyl ether head tank valve, add half of the amount of deionized water and the entire amount of propylene glycol methyl ether and sodium alginate, stop heating when the steam temperature in the kettle reaches 65-70 ° C, and at the same time Start the stirring function to heat the material evenly and stir for 20-35 minutes;

[0024] (3) After stirring evenly, add fillers, pigments and ethylenediaminetetraethylene, stir at high speed for 20 minutes, then pump into a sand mill and grind until the fineness is qualified. The reducing agent and auxiliary agent are evenly stirred and tested to be qualified, filtered, pumped into a packaging barrel by a meteri...

Abstract

Water-based anti-radiation acrylic polyurethane finishing paint is prepared from the following components in parts by weight: 150 to 200 parts of water-based epoxy modified polyurethane resin, 200 to 300 parts of deionized water, 1 to 3 parts of propylene glycol monomethyl ether, 50 to 180 parts of fillers, 1 to 10 parts of pigments, 0.5 to 0.8 part of a reduction-preventing agent, 0.5 to 1 part of ethylenediamine tetraacetic acid, 2 to 5 parts of sodium alginate and 3 to 5 parts of aids. The finishing paint provided by the invention has strong adhesive force on various base materials; furthermore, the coating has high hardness and high wear resistance, has the effects of preventing radiation, releasing negative ions and the like, and is environmentally-friendly pollution-free paint coating.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a water-based anti-radiation acrylic polyurethane topcoat. Background technique [0002] With the continuous progress of society, the awareness of environmental protection in various countries continues to increase. However, the widely used solvent-based coatings contain a large amount of volatile organic compounds (VOC), which are toxic, flammable, pollute the atmosphere, and cause harm to the environment and human body. Therefore, in order to reduce the pollution of these organic solvents to the environment, my country has included water-based coatings in the future development direction of industrial coatings. However, the water-based industrial coatings currently used in my country on floor coatings, metal antirust paints and ship coatings are not ideal in terms of water resistance, chemical resistance, radiation protection, abrasion resistance and weather resistance.
