Problems solved by technology

However, the service life of existing acrylic polyurethane coatings is 5 to 10 years. If the service life exceeds the service life, the coating will show a sharp loss of light and discoloration. , so that the shutdown
For the towers of wind power generation, after the corrosion protection of the steel structure fails, maintenance is also difficult and costly due to situations such as high-altitude operations and suspension of operation.
[0003] Application No. 200710303467.3 of the Chinese patent "A Surface Insulating Enamel for Wind Power Generation and Its Preparation Method" describes that the surface insulating enamel for wind power generation can only use tetrafluororesin, and the weather resistance of the prepared enamel is only 2500-2800 Hours, the salt spray resistance is only 1300-1500 hours, and toxic xylene is used as a solvent in the production and preparation process, which is more harmful to production operators and construction application personnel

Abstract

The invention relates to fluorocarbon finish paint for the corrosion protection of wind power equipment and a preparation method thereof, belonging to the technical field of the coating. The fluorocarbon finish paint for the corrosion protection of the wind power equipment comprises coating and solidified agents, wherein the using amount of the solidified agents is 7-12 percent of the weight of the coating, the coating is prepared from the following raw materials by weight percent: 55-75 of fluorocarbon resins, 0-10 of epoxide resins, 10-30 of pigment fillers, 0.01-2 of dispersing agents, 0.01-0.5 of flatting agents, 0.01-0.3 of siccatives, 0-5 of other auxiliary agents and 10-30 of mixed organic solvents. The fluorocarbon finish paint for the corrosion protection of the wind power equipment can replace acrylic polyurethane coating universally used in the market and obviously enhance the corrosion protection effect of the wind power equipment on the basis of no change of an original coating technique, thereby having markedly prolonged service life.

Description

technical field [0001] The invention relates to a wind power generation anticorrosion coating and a preparation method thereof, in particular to a fluorocarbon topcoat for wind power generation equipment anticorrosion and a preparation method thereof. Background technique [0002] Wind power generation equipment is mainly composed of blades, fans and towers, among which the tower is the main part that needs to be painted. The wind farm where the wind power station is located is an outdoor environment with harsh natural conditions. The wind force is above level 4 all year round, accompanied by wind and sand. Influenced by high temperature changes; for towers located at the seaside, they are also subject to erosion by water vapor, salt spray and splashing of sea spray, making them extremely vulnerable to corrosion. Therefore, anti-corrosion is a prominent concern of every wind power station. Excellent anti-corrosion protection can ensure a longer service life of wind power ge...
