Antibacterial antifouling polyurethane material as well as preparation method and application thereof

The invention provides an antibacterial antifouling polyurethane material as well as a preparation method and application thereof, and belongs to the technical field of polyurethane materials. The preparation method comprises the following steps: mixing a silane coupling agent, triethylamine, water, nano-zinc oxide and an alcohol solvent to carry out modification reaction to obtain modified nano-zinc oxide, mixing the modified nano-zinc oxide with isophorone diisocyanate, polytetrahydrofuran glycol and polycarbonate diol to carry out prepolymerization reaction to obtain a prepolymerization product, mixing the prepolymerization product with 2, 4-diphenyl-1, 3-pentanediol, and carrying out polymerization reaction to obtain a prepolymer; 2, 2-bis (hydroxymethyl) propionic acid, N-methyl pyrrolidone and acetone are mixed for a chain extension reaction, and a chain extension product is obtained; mixing the chain extension product with triethylamine, carrying out a neutralization salt-forming reaction to obtain a n
