Problems solved by technology

[0009] To sum up, there are many wind turbines in China to produce clean electricity, but their blades are prone to frost in frosty weather, which increases the weight of the blades, reduces their efficiency, and even causes damage to machines and personnel
People have done a lot of work to improve this situation, such as installing resistance wires on the surface of the blades to heat the blades, etc., but this method wastes a lot of electric energy and does not fundamentally solve the problem of anti-icing

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments.

[0032] An anti-icing wind turbine blade, the surface of the PVC heat shrinkable film base material is treated with CF 4 After etching, it becomes a rough surface with multiple grooves and pits, and a PTFE coating is deposited on the rough surface. The grooves, pits and PTFE coating form a tight cross-linked network micro-nano surface structure, CF via ionic body 4 Etching the surface of the PVC heat-shrinkable film substrate provides a premise guarantee for improving the bonding fastness between the coating and the PVC heat-shrinkable film. In addition to roughening the surface of the film, CF4 plasma pretreatment introduces fluorine-containing groups, which provides the possibility for the deposition of fluorine-containing groups in the next step, and then improves the bonding fastness between the two, and strengthens the PTFE coating The combination with the substrate...

Abstract

The invention relates to the technical field of wind power generation, in particular to an anti-icing wind power generator blade and a fabrication process thereof. A PVC heat contraction membrane which is used for preventing icing of the wind power generator blade under the low-temperature weather condition is disposed on the wind power generator blade. The PVC heat contraction membrane comprisesa PVC heat contraction membrane base material; the surface of the PVC heat contraction membrane base material is subjected to CF4 etching to form a rough surface provided with a plurality of grooves and concave pits; a PTFE coating is deposited on the rough surface; and a tight cross-linked network-shaped micro-nano surface structure is formed by the grooves, the concave pits and the PTFE coating.A wind power generator does not need to stop, the power generating capacity of the wind power generator is not affected, manpower and material resources are saved, power-on heating is not needed, electric energy is saved greatly, normal work of the wind power generator is not affected, the icing rate of an existing wind power generator blade is lowered fundamentally, thus in the premise of no damage to equipment and no waste of energy, the utilization ratio of an existing wind power generator in the cold weather is improved, and the power generating capacity in winter is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an anti-icing wind power generator blade and a preparation process thereof. Background technique [0002] Wind energy is a clean and renewable energy source. Our country is very rich in wind energy resources. At present, the wind energy reserves that can be developed are as high as 1 billion kilowatts, and the wind energy reserves on land alone reach 253 million kilowatts. Wind turbines can convert wind energy into mechanical energy, and then into electrical energy, alleviating the energy shortage caused by the combustion of oil, coal, and natural gas for power generation. Especially in grasslands, plateaus and coastal areas where energy is scarce or transportation is inconvenient, it is the general trend to use wind energy to produce clean electricity. Today, my country's wind power industry has entered a stage of rapid development, known as the world's first win...
