The invention discloses a
radiation protection water-in-water multicolor paint. The
radiation protection water-in-water multicolor paint is prepared from basic paint, protection liquid
cement and an outer wrapping solution. The basic paint is prepared from, by weight, 1-5 parts of hydroxypropyl methylcellulose, 2-4 parts of glycol, 1-5 parts of
dimethyl sulfoxide, 1.5-2.5 parts of nanometer titania, 15-20 parts of kaolin, 8-15 parts of
tourmaline powder, 25-40 parts of octaphenyl polyhedral oligomeric
silsesquioxane modified sulfonated
polyimide, 0.1-0.3 part of a defoaming agent and 2-6 parts of
bamboo charcoal. The protection liquid
cement is prepared from, by weight, 25-50 parts of water, 0.5-0.9 part of
sodium pyrophosphate, 0.15-0.25 part of lignocellulose and 1-2 parts of
polyvinyl alcohol. The outer wrapping solution is prepared from, by weight, 18-28 parts of amino-end-capping sulfonated polybenzimidazole, 0.2-0.8 part of lignocellulose, 1-2 parts of glycol, 1-5 parts of
dimethyl sulfoxide and 0.1-3 parts of KH-560. The invention further discloses a preparing method of the
radiation protection water-in-water multicolor paint.
