Problems solved by technology

[0004] However, the surface of the decorative textured powder coating is uneven, especially the high decorative textured powder coating, which is easy to breed bacteria and difficult to integrate with antibacterial agents
Therefore, no powder coating literature reports containing high decorative texture agent and antibacterial agent have been found so far.

Abstract

An antibacterial powder paint able to generate decorative vein is prepared from thermosetting resin, nano-class antibacterial 0.1-3 wt.% agent, vein generating agent 0.5-5 wt.% and metallic pigment through proportionally high-speed mixing for 3-5 min, high-temp extruding out, cooling, pressing, breaking, pulverizing and sieving by 140 meshes. Its advantages are high antibacterial power and high decorative effect.

Description

technical field [0001] The invention relates to an antibacterial powder coating and a manufacturing method thereof, in particular to a powder coating with high decorative texture and antibacterial performance and a manufacturing method thereof. Background technique [0002] Electrostatic spraying and other processes are used to spray thermosetting powder coatings such as polyester on the metal surface, which not only makes the surface of the workpiece smooth and beautiful, but also a coating process with less pollution. Compared with ordinary coatings, it has more development prospects. However, the metal surface coated with powder coating is still unavoidably affected by harmful microorganisms such as bacteria and molds. For example, refrigerators, freezers, dishwashers, shells of washing machines, kitchen cabinets, food racks in stores and other places that are often in contact with water will multiply bacteria and mold when the temperature is suitable; food processing wor...
