Abstract

The invention relates to a preparation method of solvent-based two-component wind turbine blade protective primer. The preparation method comprises the steps of preparing a component A and a component B; and mixing the components A and B at a ratio of (8-10):(1-2), and uniformly stirring to obtain the solvent-based two-component wind turbine blade protective primer. The protective primer prepared by the method provided by the invention has the advantages of excellent adhesion, rapid drying speed and good compatibility, is suitable for thick film coating, and improves work efficiency.

Description

technical field [0001] The invention belongs to the technical field of preparation of organic polymer compounds, and in particular relates to a preparation method of a solvent-based two-component wind power blade protective primer. Background technique [0002] With the rapid and sustainable development of my country's economy, the demand for energy is also growing rapidly. Wind energy, as a green renewable energy, has received more and more attention in my country. Especially in recent years, the wind power industry in my country is developing rapidly. The speed of development is developing, and already has a certain foundation. Wind power blades are one of the important components of wind turbines, and they will be exposed to harsh environments such as strong ultraviolet rays, sandstorms, high temperatures, and cold currents for a long time. The blades will face strong erosion and erosion of sand, dust, rain, and other substances during normal operation. [0003] At presen...
