摘要：To synthesize a quick-drying type of radioactive contamination detergent, a solvent type of detergent based on polyurethane was designed. And the synthetic formula of the detergent was studied by theoretical calculation and experiment. Through theoretical calculation, the basic molar ratio of toluene diisocyanate, chain extender, and polyether polyol were 1.73:0.73:1. The effects of the type of chain extenders and the content of catalysts on the performance of decontamination material were studied by formula experiment. The optimized formulation of detergent was obtained and a quick-drying type of radioactive contamination detergent was synthesized by prepolymer process. The decontamination effect of the detergent on uranium dust was verified on different surfaces, and both decontamination rates exceeded 90%.
