Description

Technical Field

[0001] The invention relates to the field of powder coating production, and more specifically to an environmentally friendly thermosetting powder coating production system and a processing method thereof. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coatings are divided into two categories: thermoplastic and thermosetting. Thermoplastic powder coatings have poor coating film appearance (gloss and leveling) and poor adhesion to metal, so they are rarely used in the field of automotive coating. Automotive coating generally uses thermosetting powder coatings. Thermosetting powder coatings use thermosetting synthetic resin as the film-forming material. During the drying process, the resin first melts and then solidifies into a smooth and hard coating film after chemical cross-linking. The coating film appearance, various mechanical properties and corrosion resistance formed by this kind of coating can meet the requirements of automotive finishing.

[0003] In the process of producing environmentally friendly thermosetting powder coatings, it is necessary to crush and grind the raw materials. The existing patent for a powder coating grinding device, patent announcement number CN210875593U, includes a metal cylinder, a motor, a pulley, a transmission belt, and a central shaft. The metal cylinder is a sandwich structure, and its outer wall is respectively provided with a water outlet and a water inlet; a feed port is provided on the top wall of the metal cylinder cavity, a through hole is provided in the center of the top wall, a partition is provided in the cylindrical cavity, a sieve hole is provided on the partition, and a through hole for installing the central shaft is also provided in the center of the partition. The central shaft is fixedly installed in the center of the metal cylinder through the through hole on the top wall of the metal cylinder and the through hole on the partition; a pressure roller bracket is provided on the central shaft, and the pressure roller is rotatably installed on the pressure roller bracket; a pulley is fixed on the upper end of the central shaft, and is connected to the motor through a transmission belt, and a discharge port is provided at the funnel-shaped bottom of the metal cylinder. The utility model can realize high-efficiency grinding of coating particles, and effectively cool down the grinding device through a cooling system.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the powder coating grinding device proposed in the above-mentioned patent technology is actually used to grind the raw materials for producing environmentally friendly thermosetting powder coatings, on the one hand, when the raw materials are large in volume, direct grinding is likely to cause the defect of low grinding efficiency; on the other hand, the ground raw materials cannot be repeatedly ground during the grinding process, resulting in the raw materials being of different sizes after grinding, and the powder coating grinding device cannot dry the raw materials during the actual grinding process, resulting in the moisture in the air being easily absorbed by the raw materials, causing inconvenience to subsequent production.

[0005] Therefore, we proposed an environmentally friendly thermosetting powder coating production system and processing method to solve the above problems. Summary of the invention
