The utility model relates to the field of composite materials, in particular to a waterproof composite fabric. Comprising a fabric layer made of a polyester material and further comprises a bottom material layer made of the polyester material, the upper surface of the bottom material layer and the lower surface of the fabric layer are bonded with film layers through glue layers respectively, the fabric layer and the bottom material layer are both made of polyester fibers, and the weight percentage of the polyester fibers adopted by the fabric layer and the bottom material layer is 1: 0.15-0.35. Cilia made of polyester materials are distributed on the upper surface of the fabric layer. A product made of the waterproof composite fabric has the effects of being waterproof, antifouling, high in strength, long in service life and high in body feeling comfort degree of a user.

This invention belongs to the field of marine protective coating technology, specifically relating to a super-corrosion-resistant powder coating for marine facilities and its preparation method. Addressing the current problem of mutual constraints among antifouling, anti-corrosion, and hydrophobic properties in coatings, this invention constructs a double-layer coating by employing a sequential electrostatic spraying process for the bottom and top layers of powder, followed by a single co-curing process to form a composite coating. The bottom layer comprises carboxylated liquid polybutadiene-modified epoxy resin and phosphate-modified flake zinc-aluminum powder, imparting excellent adhesion, flexibility, and physical shielding properties to the coating. The top layer comprises silane-modified nano-silica and modified antifouling agents, providing superhydrophobic, self-cleaning, and active antifouling functions, thereby enabling applications in harsh marine environments.
