The invention relates to an anti-graffiti and scrubbing-resistant coating composition. The raw materials of the anti-graffiti and scrubbing-resistant coating composition comprise a component A and a component B, wherein the mass ratio of the component A to the component B is 100: (20-40); the component A comprises hydrophobic modified hydroxy acrylic resin, and the component B comprises a curing agent and alcohol ether esters; the hydrophobic modified hydroxy acrylic resin is prepared from hydrophobic gel, a fluorine surfactant and hydroxy acrylic resin; and the hydrophobic gel is prepared from polymethylsilane and alkoxy silicon resin. The invention also comprises a preparation method of the anti-graffiti and scrubbing-resistant coating composition. The product provided by the invention is energy-saving and environment-friendly, has low VOC, solves the problem of poor anti-graffiti effect of a water-based coating, and has a stain resistance score up to 87 scores. According to the method, the defect that the water-based coating is poor in stain resistance stability is overcome, after 10000 times of scrubbing resistance, the stain resistance still reaches 85%, and almost no attenuation exists.
