NOVELTY - An antibacterial reinforced low temperature resistant slow-resilience polyurethane sponge comprises 40-60 pts. wt. slow-resilience polyol, 40-60 pts. wt. base polyether polyol, 0-20 pts. wt. polymer polyol, 5-10 pts. wt. antibacterial enhancer, 5-10 pts. wt. low temperature resistant agent, 1.2-2.4 pts. wt. amine catalyst, 0.4-1.2 pts. wt. tin catalyst, 0.8-1.2 pts. wt. surfactant, 1.0-2.0 pts. wt. foaming agent, and 40-65 pts. wt. isocyanate. USE - Antibacterial reinforced low temperature resistant slow-resilience polyurethane sponge. ADVANTAGE - The antibacterial reinforced low temperature resistant slow-resilience polyurethane sponge has enhanced strength, low temperature resistance and antibacterial properties. The preparation method is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the antibacterial reinforced low temperature resistant slow-resilience polyurethane sponge, which involves mixing slow-resilience polyether polyol, basic polyether polyol and polymer polyol, adding antibacterial enhancer, low temperature resistant agent, amine catalyst, tin catalyst, surfactant, foaming agent, stirring, adding isocyanate, stirring, pouring into mold, curing, demolding, and cutting.
