By using special epoxy resin spray film-forming equipment, epoxy resin coating can be evenly sprayed on the surface of the object to form a thin film with excellent anti-corrosion, waterproof and wear-resistant properties. Among them, water-based epoxy resin coating spray film-forming equipment has unique advantages in manufacturing composite materials and improving the performance of materials.

Secondly, after the coating is completed, the coating on the surface of the object will not form a film immediately, and natural drying may take a long time. In addition, the drying quality of the coating is difficult to guarantee, which affects the performance of the coating and has poor practicality. Utility Model Content

[0023] See also Figure 1-4An isolation cover 17 is fixedly connected to the interior of the paint box 11, and two heating lamps 18 are installed inside the paint box 11 at equal intervals in an array. Through the arrangement of the isolation cover 17 and the heating lamps 18 and other structures, after the painting is completed, the heat of the heating lamps 18 can promote the curing process of the water-based epoxy resin paint, so that it can form a tough and smooth coating more quickly, accelerate the drying process of the paint, shorten the waiting time for drying after painting, and thus improve production efficiency.

[0024] See also Figure 1-4 A slide groove 20 is opened inside the paint box 11, and the flow pipe 7 is slidably connected inside the slide groove 20.

[0025] The specific implementation process of the utility model is as follows: when using this equipment for spraying, add epoxy resin paint into the storage bin 9 through the main material port, start the motor 2, the shaft 3 rotates, the stirring blade 4 stirs to ensure the fluidity of the paint in the storage bin 9, start the pump 13 to extract it, and it flows to the inside of the flow pipe 7 through the delivery pipe 14, and the transmission wheel 5 rotates. When the transmission wheel 5 rotates to one side of the moving button 6, the moving rod 6 moves to the right through the gear meshing. When the transmission wheel 5 rotates to the other side of the moving button 6, the moving rod 6 moves to the left, thereby driving the flow pipe 7 to move left and right. The spray head 8 sprays the surface of the object placed on the placement plate 15 in a more comprehensive manner. The left and right movement of the spray head 8 increases the coating area, reduces the spraying time and the number of spraying times, thereby improving the coating efficiency and avoiding The coating is accumulated and flowed, thereby forming a more uniform coating, improving the adhesion of the coating, and providing a better protective effect of the coating. It should be noted that water-based epoxy resin coatings can be selected from water-soluble anionic resin coatings (anodic electrophoretic coatings) or water-soluble cationic resin coatings (cathodic electrophoretic coatings). Such coatings often use water-soluble curing agents, such as melamine formaldehyde resins, benzoguanamine formaldehyde resins, urea-formaldehyde resins, and isocyanate blockers, among which the resin of the water-soluble anionic resin coating is obtained by reacting an epoxy resin with a high hydroxyl content with an acid and anhydride, and then neutralizing with an amine to obtain a water-soluble anionic resin, while the resin of the water-soluble cationic resin coating is obtained by adding an epoxy resin to an amine, introducing a semi-blocked polyisocyanate as a cross-linking agent, and finally neutralizing with an acid;

[0026] In addition, after the painting is completed, the heating lamp 18 in the isolation cover 17 will continue to emit heat to promote the curing process of the paint, allowing it to form a chemically cross-linked network structure more quickly, increase the hardness and wear resistance of the coating, reduce the gaps and bubbles between the paint and the object, and enhance its protective effect and service life.
