Abstract

The invention relates to a protective coating for aerogenerator vanes and a preparation method thereof, wherein the protective coating has the advantages of excellent ultraviolet radiation resistance, abrasion resistance, stain resistance, corrosion resistance, adhesive force and flexibility. The preparation method uses hydroxyl acrylate resin as a base material of the surface protective coating for the aerogenerator vanes and uses the mixture of HDI biuret and HDI tripolymer as a curing agent. The coating consists of a component A and a component B, wherein the component A comprises the following materials in portion by weight: 10 to 55 portions of the hydroxyl acrylate resin, 1 to 5 portions of abrasion resistant and stain resistant auxiliary agent, 0.2 to 0.4 portion of ultraviolet stabilizer, 10 to 15 portions of environment-friendly organic solvent, 15 to 20 portions of pigments and fillers, 2 to 5 portions of delustering agent, 0.15 to 0.55 portion of dispersing agent, 0.01 to 0.3 portion of drying agent, and 0.25 to 0.55 portion of levelling agent; the component B comprises 1 to 15 portions of the HDI biuret and 1 to 15 portions of the HDI tripolymer; and the mass ratio of the component A to the component B is 2-6:1. When in use, the components A and B are mixed and stirred evenly in proportion, and then the mixture is adjusted to proper viscosity for construction by using a spraying method.

Description

technical field [0001] The invention relates to a protective paint and a preparation method, in particular to a preparation method of a two-component acrylic polyurethane protective paint for a wind power generator blade of a wind power generation device. Background technique [0002] The most critical and core part of the wind power generation device is the blade. The design of the blade and the materials used determine the performance and power of the wind power generation device, and also determine the cost of the wind power generation unit. Wind power blades account for about 20% of the cost of the entire device for wind power generation, and the materials and processes used to manufacture the blades are decisive for their cost. The materials used for wind turbine blades use different composite materials according to the length of the blades. At present, glass fiber reinforced unsaturated polyester resin and glass fiber reinforced epoxy resin are the most commonly used, ...
