▎ 摘　　要

NOVELTY - Single component high permeability rusty anticorrosive paint comprises 30-50 pts. wt. polyurethane pre-polymer, 30-40 pts. wt. wetting solvent, 10-20 pts. wt. pigment filler, 5-18 pts. wt. water-removing reinforcing agent and 1.75-4.75 pts. wt. auxiliary agent. The auxiliary agent comprises dispersant, thixotropic agent and antifoaming agent. USE - The single-component high permeability rusty anti-corrosive paint is used in the anti-corrosion field (claimed). Can also be used for corrosion protection of engineering equipment and facilities. Uses include but are not limited to large buildings, bridges, ships, signal tower and complex steel structure component. ADVANTAGE - The single component high permeability rusty anticorrosive paint has low viscosity, high wetting and so characteristics, it can penetrate into the rust surface, and trigger reaction with water in the air to form a dense cross-linked coating, so it can be coated with rust, high adhesive force, strong surface tolerance. It has excellent salt mist resistant performance. The coating can be directly coated on the rustiness or corrosion steel base material, realizing excellent protection effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of the single component high permeable rusty anticorrosive paint comprising: (1) under the protection of inert gas, placing isocyanate monomer and polyol at 70-80 ℃ for 1-2 hours to obtain the polyurethane prepolymer; (2) uniformly mixing polyurethane prepolymer, wetting solvent, and water removing reinforcing agent at normal temperature; (3) adding the pigment filler and auxiliary agent, mixing uniformly to obtain the single component high permeability rusty anticorrosive paint.
