NOVELTY - Preparing modified nano graphene oxide stability-enhancing synergistic anti-freezing foam detergent, involves (a) preparing hydroxylation modified nano graphene oxide, (b) preparing nano composite modified graphene oxide by taking the hydroxylated modified nano graphene oxide as a raw material, (c) uniformly mixing 0.01-3 pts. wt. nano composite modified graphene oxide, 0.5-2 pts. wt. biomass surfactant, 1-10 pts. wt. antifreeze, 0.01-0.05 pts. wt. thickener and 84.95-98.48 pts. wt. water, ultrasonically dispersing for 20-30 minutes, and stirring for 1-3 minutes under stirring speed is 2000-5000 rad/min to prepare target product. USE - Method for preparing modified nano graphene oxide stability-enhancing synergistic anti-freezing foam detergent. ADVANTAGE - The method uses biomass surfactant as foaming agent, which is cost-effective and biodegradabile. The antifreeze foam detergent has good foam stability at low temperature, long foam half-life time, non-corrosiveness, less secondary pollution and environmental friendliness. The preparation method is simple to operate, eco-friendly, and has good application prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using the modified nano graphene oxide stabilized and synergized antifreezing foam detergent, which involves: spraying modified nano-graphene oxide stabilized and synergistic antifreezing foam decontamination agent on the surface of the radioactively contaminated board, and carrying out decontamination at a low temperature of (-)20-0℃ for 20-40 minutes, and further collecting the foam to complete the decontamination. The plate is pottery, paint, stainless steel, glass, marble and cement.
