Problems solved by technology

However, at present, the liquefaction of room-temperature-curable fluorocarbon resin raw materials requires a large amount of strong solvent support, and the VOC content of fluorocarbon topcoats has never been reduced. In addition, toxic isocyanates need to be used for curing. These are not in line with the environmental protection properties of wind energy itself.

Abstract

The invention discloses a polysiloxane topcoat for wind power generation equipment. A component A of the topcoat comprises the following compositions in percentage by mass: 50 to 70 percent of acrylic modified polysiloxane resin, 0.1 to 1 percent of wetting and dispersing agent, 1 to 3 percent of thixotropic agent, 10 to 20 percent of lightfast pigment and filler, 5 to 15 percent of wear-resistant filler, 5 to 15 percent of impact-resistant filler, 0.5 to 2 percent of ultraviolet absorber, 0.1 to 2 percent of leveling agent and 1 to 5 percent of low-toxicity organic solvent; the component B is amino alkoxy silane; and the polysiloxane topcoat is prepared in a mass ratio of the acrylic resin to the amino alkoxy silane of 8-12:1. The topcoat has the advantages of outstanding weather resistance, excellent scratch, impact, wear, low temperature and corrosion resistance, hydrophobicity and low surface energy, has the comprehensive performance not lower than that of the conventional fluorocarbon topcoat for the wind power generation equipment, can form a film with the maximum thickness of 200mu m at one time, can shorten the construction period, has high solid content, is not cured by isocyanate, and is favorable for protecting environment.

Description

technical field [0001] The invention relates to an anticorrosion coating technology, in particular to a polysiloxane topcoat for wind power generation equipment. Background technique [0002] As a renewable and clean energy, wind power has become an energy field that countries around the world are competing to develop. Wind turbines are mostly located in deserts, mountains, coasts and seas away from human habitation, and need to withstand the erosion of various natural factors such as strong wind, sand, rain, frost, ultraviolet radiation and waves. Therefore, in order to ensure a longer service life of wind power equipment, It must be protected against corrosion. The maintenance of wind power equipment is relatively difficult. In addition, in order to reduce maintenance costs, long-term protective coatings are usually used to extend the first overhaul period as much as possible. At present, the most commonly used coating supporting system is zinc-rich primer / epoxy miracic ...
