Hydrophobic anti-drag composite material, preparation method and coating

The invention discloses a hydrophobic anti-drag composite material. The formula of the composite material comprises the following components: double-component hydroxyl acrylic resin, fluorine-containing modified nano SiO2 and mixed wax, wherein the mixed wax comprises paraffin, palm wax and beewax. Correspondingly, the invention further discloses a preparation method of the hydrophobic anti-drag composite material and a hydrophobic anti-drag composite coating. According to the hydrophobic anti-drag composite material disclosed by the invention, the double-component hydroxyl acrylic resin, thefluorine-containing silane modified nano SiO2 and the three different waxes are used as raw materials, and in the preparation method, the fluorine-containing silane modified nano SiO2 and the three different waxes are firstly mixed uniformly and then mixed with the double-component hydroxyl acrylic resin, so that a multi-micro-nano composite structure is obtained; and therefore, the hydrophobic coating has good hydrophobi
