The invention relates to a production technology of water bands, in particular to a production technology of a novel coating water band. According to the technical field, the production technology of the novel coating water band includes the following steps that TPU paint is diluted, pigment and a special curing agent are added, and TPU slurry is prepared; air is introduced into a liner pipe of the water band to expand the water band to be plump, and the TPU slurry is injected into a mould cavity of a band dyeing mould; the water band penetrates through the band dyeing mould, and the surface of a fabric layer of the water band is evenly coated with the TPU slurry; the water band is pulled to an oven, dried and cured, and a polyurethane film coating is formed; a proper quantity of TPU particles are contained in an extruder after being dried, an extruded film wraps the coating water band obtained in the last step, and a polyurethane abrasion-resistant layer is formed on the coating water band; after cooling, winding, cutting and packaging are conducted. The technology has the advantages that TPU viscosity is large, the solid content is large, the film coating is thick, and the water band is much better than existing products in the aspects of weather resistance, corrosion resistance, puncture resistance, abrasion resistance and service life.
