Anti-corrosion and super-weatherability powder coating and preparation process thereof

Abstract

The invention relates to an anti-corrosion and super-weatherability powder coating. The coating comprises a base paint and a face paint, wherein the base paint is an anti-corrosion epoxide powder coating and comprises the following components in percentage by mass: 53 to 62 percent of epoxy resin, 3 to 12 percent of curing agent, 5 to 15 percent of pigment, 15 to 25 percent of filler and 2 to 8 percent of auxiliary agent; and the face paint is a super-weatherability polyester powder coating and comprises the following components in percentage by mass: 58.5 to 62.4 percent of carboxyl-terminated polyester resin, 2.6 to 6.5 percent of curing agent, 10 to 20 percent of pigment, 10 to 20 percent of filler and 2 to 6 percent of auxiliary agent. The anti-corrosion and super-weatherability powder coating is a powder coating with super corrosion resistance and super adverse weather condition resistance, such as super ultraviolet ray resistance and the like. The adhesive force between the base paint and the face paint is good; the coating efficiency is high; and the powder coating causes no pollution to environment. The invention also provides a preparation method of the powder coating.

Description

1. Technical field [0001] The invention relates to a powder coating, in particular to a heavy-duty anti-corrosion and super-weather-resistant powder coating and a production process thereof. 2. Background technology [0002] With the rapid development of industrial production technology in various countries in the world, the demand for energy continues to grow, the use of limited resources such as oil and coal is restricted, and the use of unlimited resources such as hydropower, wind power and solar energy is favored by people and is becoming more and more popular. attention from all over the world. In recent years, while strengthening the prospecting and deep mining of oil and coal, my country has also attached great importance to wind power generation, and it has developed rapidly in the northeast and northwest regions where wind resources are abundant. In order to ensure the safety and long-term service life of wind power generation equipment, anti-corrosion coatings and...

Problems solved by technology

In addition, these solvent-based coatings are all self-drying coatings, and the thickness of each coating should not be too thick. Generally, the thickness of one coating is 20 microns to 30 microns. It usually takes 24 hours before the coating film is completely dry before it can be painted again. One piece, so it takes a long time to coat a thickness of nearly 300 microns, and the production labor efficiency is also very low
