The invention discloses a method for preparing an antibacterial and stain-resistant polyurethane tire. First, a wear-resistant polyurethane with a relatively large molecular weight is obtained by reacting polyethylene adipate, isophorone diisocyanate and diethylaminoethanol, and the auxiliary Antibacterial filler, lubricant magnesium stearate and nano titanium dioxide are used to further increase the antibacterial property, lubricity, wear resistance and hardness of solid inner tube; The aminoethanol reaction obtains a wear-resistant polyurethane with a smaller molecular weight, and supplemented with a large amount of antibacterial fillers, lubricant calcium stearate, and nano-titanium dioxide. Polyurethane tires have good wear resistance and antibacterial stain resistance from the outside to the inside; the triangular wear pattern and diamond wear pattern formed on the surface of the antibacterial and antifouling layer further increase the lateral force bearing range of the tire and improve the use of the tire life. |
