[0002] Polyurethane waterproof coating is a single-component polyurethane waterproof coating made of isocyanate-containing prepolymers formed by addition polymerization of isocyanate, polyether, etc., with catalysts, anhydrous additives, anhydrous fillers, solvents, etc., and processed by mixing and other processes. This type of coating is a reaction-curing coating with the characteristics of high strength, high elongation, and good water resistance. It is widely used in waterproofing, anti-seepage, and moisture-proofing of roofs, toilets, basements, reservoirs, and walls. When polyurethane waterproof coating is being constructed, in order to improve construction efficiency, a coating device is usually used to apply the polyurethane waterproof coating to reduce the labor intensity of the staff, but it still has the following disadvantages in actual use:

[0003] 1. The utility model with the publication number CN218690841U discloses a coating device for modified polyurethane waterproof coating, wherein a stirring barrel is connected to the top of the device body, a stirring shaft is connected to the axis of the stirring barrel, a stirring rod is connected to the outer wall of the stirring shaft, a first bevel gear is connected to the bottom of the stirring shaft, a connecting block is connected to the bottom of the device body, a connecting rod is connected to the axis of the connecting block, one end of the connecting rod is connected to the second bevel gear, one end of the connecting rod is connected to the second pulley, one side of the second pulley is connected to the motor, and the outer wall of the motor is connected to a fixing frame, a cleaning roller is connected to the front end of the device body, one end of the cleaning roller is connected to the first pulley, and the outer walls of the first pulley and the second pulley are sleeved with a conveyor belt, and the coating device for modified polyurethane waterproof coating can stir the coating, clean the ground, and improve the coating effect, but in actual operation, due to the characteristics of the polyurethane waterproof coating, it is usually necessary to clean the coating device in time after the construction work is completed to avoid the residual coating from clogging the device, but timely cleaning greatly increases the labor intensity of the staff;

[0004] 2. When applying the polyurethane waterproof coating, the coating device often directly applies the coating to the working surface, and then solidifies the polyurethane waterproof coating by natural drying. However, in actual operation, the curing speed of the polyurethane waterproof coating is often affected by the environment. When the ambient humidity is low, the polyurethane waterproof coating often takes a long time to cure, reducing construction efficiency. Utility Model Content
