NOVELTY - A radiation radon-absorbing radiation-resistant coating comprises 5-50 parts mass graphene-polyacrylic acid, 90-120 parts mass matrix resin, 330-370 parts mass deionized water and 450-550 parts mass pigment. The graphene-polyacrylic acid is prepared by urethanization of modified graphene (I) and polyacrylic acid. USE - Radiation radon-absorbing radiation-resistant coating is used for radon-enriched space (claimed). ADVANTAGE - The radiation radon-absorbing radiation-resistant coating has excellent radon adsorption characteristics in air. The radiation radon-absorbing radiation-resistant coating improves living environment, and reduces harm of radon to human health. DETAILED DESCRIPTION - A radiation radon-absorbing radiation-resistant coating comprises 5-50 parts mass graphene-polyacrylic acid, 90-120 parts mass matrix resin, 330-370 parts mass deionized water and 450-550 parts mass pigment. The graphene-polyacrylic acid is prepared by urethanization of modified graphene of formula (I) and polyacrylic acid. INDEPENDENT CLAIMS are included for the following: (1) preparation of radiation radon-absorbing radiation-resistant coating, which involves preparing modified graphene by dissolving graphene in N,N-dimethylformamide, adding hexamethylene diisocyanate, reacting mixture with graphene and centrifugally washing mixture to remove unreacted hexamethylene diisocyanate, preparing graphene-polyacrylic acid by dissolving modified graphene in N,N-dimethylformamide, adding polyacrylic acid, stirring mixture and reacting graphene and polyacrylic acid, and preparing radiation radon-absorbing radiation-resistant coating by mixing graphene-polyacrylic acid, matrix resin, pigment filler, deionized water and optional additive; and (2) application of radiation radon-absorbing radiation-resistant coating used for radon-enriched space.
