Problems solved by technology

[0003] At present, the existing products in the market mainly use the bactericidal effect of silver ions in silver-based antibacterial agents, but the disadvantage is that the silver ions in silver-based antibacterial agents are easy to dissolve, and the durability is poor, and the silver ions gradually appear after the coating film is cured for 24 hours. Release, play a bactericidal effect, it can be seen that this kind of antibacterial powder coating antibacterial effect is slow

Abstract

The invention discloses an antibacterial powder coating, prepared from the following raw materials by weight: 25 to 35 percent of epoxy resin, 25 to 35 percent of polyester resin, 0.8 to 1.5 percent of flatting agent, 0.8 to 1.5 percent of smooth degasifier, 0.3 to 1.5 percent of antibacterial agent and 25.5 to 48.1 percent of pigment and filler. A coating film formed after the antibacterial powder coating material is sprayed and cured has excellent antibacterial performance, and takes effect quickly in antibacterial capability, and the effect is long-acting and lasting.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an antibacterial powder coating. Background technique [0002] With the continuous improvement of people's living standards, the requirements for hygienic quality are also getting higher and higher. How to have effective antibacterial and sterilizing is the challenge that people put forward to modern life. The antibacterial powder coating industry is still in the development stage. Solving the application of antibacterial materials in powder coatings is a common issue facing the powder coating industry. [0003] At present, the existing products in the market mainly use the bactericidal effect of silver ions in silver-based antibacterial agents, but the disadvantage is that the silver ions in silver-based antibacterial agents are easy to dissolve, and the durability is poor, and the silver ions gradually appear after the coating film is cured for 24 hours.
