The present invention is a preparation method of an anti-bacterial coating on a plastic surface. A preparation method of an anti-bacterial coating on a plastic surface with a better anti-bacterial effect is provided and comprises putting a plastic substrate into a PVD vacuum device; coating an anti-bacterial metallic layer on the plastic surface; and spray coating an anti-bacterial middle coating on the sample coated with anti-bacterial metallic coating. Utilizing PVD to coat antibacterial layer offsets timeliness of bacterial activity of the organic anti-bacterial coating, which allows the products with double bacterial layers have excellent anti-bacterial and bacteria-inhibited effects during their life spans. The anti-bacterial effect can not only be lasted for a long time, but also achieve high anti-bacterial efficiency (antibacterial rate is more than 99%). The product has excellent function and superior appearance, which is suitable for bath products, electronic devices, domestic appliances, cars and other industries.
