Abstract

The invention discloses high-performance wind-power generating facility coating prepared by taking organic fluorinated silicone modified elastic polyurethane-urea resin as substrate. The high-performance wind-power generating facility coating is prepared from component A and component B according to proportion. The wind-power generating facility coating has toughness, attrition resistance, high elasticity, excellent mechanical property, yellowing resistance, good colour retention, high ultraviolet resistance, high weather resistance, favorable and excellent electrical insulation, chemical stability, moisture resistance and freeze resistance. In addition, the wind-power generating facility coating has high performance and moderate cost and can strongly protect the wind-power generating facility, reduce the maintenance frequency and lower the purchasing cost of the wind-power generating facility, thereby having extremely high implementation value and social and economic benefit.

Description

technical field [0001] The invention relates to the field of wind power coatings, in particular to a high-performance wind power coating prepared by using organofluorosilicon modified elastic polyurethane urea resin as a base material. Background technique [0002] In order to alleviate the contradiction between energy supply and demand, countries all over the world are actively researching and developing new energy, especially renewable energy, so as to ensure the long-term and stable energy supply of human beings. [0003] Wind power has become the fastest-growing renewable energy in recent years, and it has begun to develop from "supplementary energy" to "strategic alternative energy". Wind power stations are exposed to harsh weather conditions for a long time, requiring effective corrosion protection. Among them, large-scale wind power equipment is expensive and the working environment is harsh, so it is inconvenient to disassemble and repair the main parts on site. Th...
