Abstract

The invention discloses a water-based fluorocarbon top coat for wind-powered blades and a method for preparing the water-based fluorocarbon top coat and relates to the field of protective paint. According to the water-based fluorocarbon topcoat for wind powered blades, through compounding an hydroxyl acrylic emulsion and a water-based fluorocarbon emulsion and crosslinking hydroxyl acyclic acid with isocyanate so as to form a netted film, thus the coating adhesion, flexibility, chemical medium resistance, wear resistance of a coating are increased; due to the addition of the water-based fluorocarbon emulsion, the weather fastness of the coating is improved, and the gloss retention, color retention and chalking resistance of the coating are excellent; under the condition of stirring a water-dispersed isocyanate curing agent at a lower speed, an ideal emulsion is formed easily through mixing, thereby ensuring the performance of paint; and because of the introduction of a light stabilizer, the lightfastness, color retention and chalking resistance of the coating are improved.

Description

technical field [0001] The invention belongs to the field of protective coatings, and in particular relates to a water-based fluorocarbon topcoat for wind power blades and a preparation method thereof. Background technique [0002] my country's "Outline of the Twelfth Five-Year Plan for National Economic and Social Development" clearly stated that during the "Twelfth Five-Year Plan" period, "the proportion of non-petrochemical energy in primary energy consumption will reach 11.4%" and the guidelines for "effectively developing wind power". During the "Twelfth Five-Year Plan" period, the newly planned capacity of my country's wind power industry is 100 million kilowatts. As an important supporting material for the wind power industry, my country's wind power coating industry market is mainly monopolized by foreign coating companies, especially blade coatings, which are almost entirely dependent on imports. [0003] In the national high-tech research and development plan (863...
