Example Embodiment

[0070] Example one:

[0071] Step 1: Synthesis of polyester

[0072] Add 26.5% adipic acid, 36.25% sebacic acid, 32.9% 1,4-butanediol, 4% trimethylolpropane to the reactor, and add the catalyst—0.2% p-toluenesulfonic acid, stabilizer— —0.15% triphenyl phosphate. The temperature is increased to 180°C, the temperature is kept for 2 hours, and then a vacuum is applied for about 1.5 hours to remove trace water and excess glycol under reduced pressure. After discharging.

[0073] The second step: The 32.9% polyester synthesized in the first step, 9.2% PTMG1500, 0.3% 1,4-butanediol, 5.6% hydroxy-terminated siloxane (molecular weight 1500), 18% xylene, melted and mixed Heat up to 130°C and reflux for dehydration, then lower the temperature to 75°C, add 9% anhydrous ethyl acetate, anhydrous cyclohexanone, start dripping 20% ​​isophorone diisocyanate, drip within 0.5 hours, add after dripping Catalyst-0.2% p-toluenesulfonic acid, kept for 3 hours, and then start to add 5% amino-terminated...

[0076] Example 2

[0077] Step 1: Synthesis of polyester

[0078] Add 66.3% sebacic acid, 12.5% ​​1,3-propanediol and 20.85% diethylene glycol to the reaction kettle, and add catalyst-0.2% p-toluenesulfonic acid, stabilizer-0.15% triphenyl phosphate . The temperature was raised to 180°C, kept for 2 hours, and then vacuumed for 2 hours to remove trace water and excess glycol under reduced pressure. After discharging.

[0079] The second step: melt 26.4% and 6.1% PTMG2000, 10.1% hydroxy-terminated polysiloxane (molecular weight 2000), 1.4% trimethylolpropane, and 18% xylene into the first synthetic polyester 26.4% and 6.1% PTMG2000, and heat to 130℃ Reflux for dehydration, then lower the temperature to 80°C, add 9% anhydrous ethyl acetate, 3% anhydrous cyclohexanone, start dripping 26% phorone diisocyanate (IPDI), drip in 0.5 hours, add after dripping Catalyst-0.2% p-toluenesulfonic acid, reacted for 2.5 hours with heat preservation, then began to add 4% amino-terminated fluoropoly...

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...
