The invention relates to a preparation method of an environment-friendly polyurethane waterproof coating. The method comprises the following steps: S1, checking a reaction kettle, S2, filling materials, S3, stirring and forming, and S4, material discharging and cleaning: a discharge port is manually opened for discharging, and a visual detection device is controlled by a central control module to detect the distribution quantity of the coating remained on the surfaces of a stirring column and a stirring paddle, and judge the cleaning mode according to the detected distribution quantity data; and if the central control module detects the coating remained on the surfaces of the stirring column and the stirring paddle again and judges that the thickness of the coating remained on the surfaces of the stirring column and the stirring paddle after primary cleaning does not meet the preset standard, the central control module preliminarily judges that the viscosity of the polyurethane waterproof coating is too high and adjusts the rotating speed of the stirring paddle. Different cleaning methods are set based on different conditions of the distribution quantity, and the first cleaning device and the second cleaning device are adjusted according to the judged cleaning methods, so that the purposes of precise cleaning and efficient cleaning are achieved.
Description
technical field [0001] The invention relates to the technical field of waterproof paint processing, in particular to a preparation method of an environment-friendly polyurethane waterproof paint. Background technique [0002] Polyurethane waterproof coatings are prepolymers containing isocyanate groups formed by addition polymerization of isocyanate and polyether, together with catalysts, anhydrous additives, anhydrous fillers, solvents, etc., and processed through mixing and other processes The single-component polyurethane waterproof coating, which is a reaction-curing moisture-curing coating, has the characteristics of high strength, high elongation, and good water resistance. Therefore, it is often used for waterproofing, anti-seepage, and moisture-proof treatment of roofs, toilets, basements, reservoirs, and walls. [0003] The existing polyurethane waterproof coating has a certain viscosity after being stirred and formed, so it is difficult to clean up the remaining i...
