▎ 摘　　要

NOVELTY - Integrated composite coating for bottom surface comprises first component and second component separately packaged. The preparation raw materials of the first component include 0-5 wt.% modified graphene, 50-70 wt.% fluorocarbon resin, 4-10 wt.% epoxy resin, 0-30 wt.% titanium dioxide, 0.2-1 wt.% dispersant, 0.6-1.8 wt.% organic soil, 10-20 wt.% organic solvent, 0.2-0.5 wt.% antifoaming agent and 0-0.4 wt.% leveling agent. The modified graphene is fluorinated graphene or zirconium phosphate-modified fluorinated graphene. The second component is isocyanate curing agent. The mass ratio of the first component and the second component is 100:10-20. USE - The integrated composite coating for bottom surface is useful in metal, building, wood surface abrasion and corrosion. The metal is a steel, a concrete, a plastic, a glass, a ceramic, or a plastic composite material. ADVANTAGE - The integrated composite coating has excellent performance, the method is simple and efficient, can be applied in one step and cured at room temperature, and has broad application prospects. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the integrated composite coating, comprising mixing the preparation raw materials of the first component to obtain the first component, when in use, mixing the first component and the second component to obtain the integrated composite coating; and coating method of the integrated composite coating, comprising coating the integrated composite coating on the surface of the substrate in one step, and curing at room temperature to obtain a composite coating.
