Description
Technical Field
The invention relates to the technical field of ice prevention and removal, in particular to an anti-icing coating and a preparation method and application thereof.
Background
Ice control technology has attracted attention in many fields. Because the wind turbine generator is exposed to the natural environment for a long time, the wind turbine generator is greatly affected by the environment and the climate, wherein the icing of the blades is the most important factor affecting the safety and the power generation of the wind turbine generator. The blade icing can lead to the change of blade airfoil, influences the unit output, can lead to the unit to shut down and produce great power curve deviation when serious, causes the generated energy loss to can influence the balance of impeller, lead to the uneven load of blade and drive part, influence the life and the operation safety of unit. In addition, the detachment of ice coating due to the rotation of the blower may jeopardize the safety of surrounding population and property. Therefore, it is very urgent and necessary to prevent ice from being removed for the wind power generator.
Compared with the traditional anti-icing mode, namely hot air/electric heating anti-icing, the anti-icing coating has extremely excellent anti-icing effect, does not need energy consumption, is energy-saving and environment-friendly, and is focused by researchers. Coating anti-icing is free of energy and system constraints and is considered to be one of the most important components of new generation anti-icing systems.
Superhydrophobic surfaces and lubricant injection surfaces are the most typical passive anti-icing surfaces, which rely on lotus leaf-inspired solid-air interfaces and nepenthes-inspired solid/liquid interfaces, respectively. Poor durability makes it difficult for these surfaces to remain functional for long periods of time in harsh external environments, particularly under high speed, high pressure or high shear conditions. The soft elastic surface is used as a newly developed anti-icing strategy, can promote the generation of interfacial fracture, leads to ice separation, realizes low ice adhesion strength, and can be used for large-area anti-icing and deicing. Its use in harsh environments is limited by the deterioration of mechanical robustness caused by the ultra-low modulus of elasticity. It remains a challenge for interfacial cracking to promote an ice-shedding interface that achieves ultra-low ice adhesion and maintains a strong mechanical robustness.

The coating had a white appearance (see fig. 1), had a low ice adhesion strength of 47kPa (see fig. 2), an elastic modulus of 1.1MPa (see fig. 3), an adhesive strength with the substrate of 4.21MPa (see fig. 4), and a thickness reduction of 90 μm (see fig. 5) after 250 cycles of grinding with a grinding wheel loaded with 250 g. It can effectively reduce the ice accumulation on the surface of the blade in dynamic environment (see figure 6).
Comparative example 1
(1) Mechanically stirring E51 type epoxy resin, and performing ultrasonic dispersion and defoaming to obtain a first dispersion liquid;
(2) Adding polyether amine into the dispersion liquid I and fully stirring to obtain a dispersion liquid II;
(3) Adding dibutyl tin dilaurate into the dispersion liquid II, and stirring to obtain a dispersion liquid III;
(4) Cleaning the wind blade and the glass substrate with a cleaning agent, and drying;
(5) Uniformly coating the dispersion liquid III on the surface of the substrate by adopting a brushing process;
(6) And standing the brushed sample for 12 hours at room temperature until the coating is fully crosslinked and cured and is completely dried and cured, so that the high-strength anti-icing coating for wind power generation is obtained.
Wherein the mass percent of the E51 type epoxy resin in the dispersion liquid III is 74.2 percent, the mass percent of the polyether amine is 24.8 percent, and the mass percent of the dibutyl tin dilaurate is 1 percent.
The coating had a transparent appearance (see FIG. 1), a relatively high ice adhesion strength of 316.4kPa (see FIG. 2), an elastic modulus of 1775.9MPa (see FIG. 3), an adhesive strength with the substrate of 6.37MPa (see FIG. 4), and a thickness reduction of 23 μm after 250 cycles of grinding with a 250g load of grinding wheel (see FIG. 5). But it is severe in dynamic environments with blade surface ice (see fig. 6).

(4) Cleaning the wind blade and the glass substrate with a cleaning agent, and drying;
(5) Uniformly coating the dispersion liquid III on the surface of the substrate by adopting a brushing process;
(6) And standing the brushed sample for 12 hours at room temperature until the coating is fully crosslinked and cured and is completely dried and cured, so that the high-strength anti-icing coating for wind power generation is obtained.
Wherein the mass percentage of the hydroxy dimethyl silicone oil in the dispersion liquid III is 90 percent, the mass percentage of the tetraethoxysilane is 9 percent, and the mass percentage of the dibutyl tin dilaurate is 1 percent.
The coating had a clear appearance (see fig. 1), had a low ice adhesion strength of 45.6kPa (see fig. 2), an elastic modulus of 0.6MPa (see fig. 3), an adhesive strength with the substrate of 2.01MPa (see fig. 4), a poor strength, no abrasion resistance after abrasion, and a thickness reduction of 130 μm after 75 cycles of abrasion with a 250g load of grinding wheel (see fig. 5).
