One silicone-modified two-component solvent-free polyurethane anti-corrosion coatings and preparation method

Description: A two-component silicone modified solvent-based polyurethane anti-corrosion coatings and preparation method, which consists of A, B consisting of two components, the component A quality synthesized by the following percentages: silicone modified polyester polyol 5 to 70%, fillers from 5 to 60%, from 10 to 50% solvent mixture, the catalyst from 0 to 0.05%, leveling agents from 1 to 5%, 0 to 0.2% coupling agent, anti-settling agent, 0.3 to 0.5%, Run wet dispersing agent 0.1 to 0.5%, the anti-skinning agent 0.2 ~ 1.4%, 0.2% to 0.5% antifoaming agent; the group B component is 5 to 50% of the TDI-TMP adduct. After the coating of the present invention has a high solids content, high adhesion, high temperature, wear-resistant, heat-resistant, acid erosion, hydrophobicity strong, construction and other characteristics at room temperature, suitable for general corrosion of metal and concrete facility, especially for power plant desulfurization chimney wall corrosion, to solve the existing anti-corrosion coating defects.
