Description
Technical Field
The invention relates to the technical field of unmanned aerial vehicle rotor coating, in particular to an anti-icing super-hydrophobic coating for an unmanned aerial vehicle rotor.
Background
An unmanned aircraft, abbreviated as "drone", and abbreviated in english as "UAV", is an unmanned aircraft that is operated by a radio remote control device and a self-contained program control device, or is operated autonomously, either completely or intermittently, by an onboard computer. Drones tend to be more suitable for tasks that are too "fool, dirty, or dangerous" than are manned aircraft. The unmanned aerial vehicle can be divided into fixed wing type, rotary wing type and flapping wing type unmanned aerial vehicles according to flight characteristics, wherein the micro rotary wing type unmanned aerial vehicle has the advantages of small size, simple structure, flexible control and the like, can take off and land vertically and hover freely, can adapt to various natural environments, has the advantages of autonomous flight and landing capability and the like, can operate in complex and dangerous environments which are not suitable for human beings to enter, and has more and more important application in the fields of scientific research institutions, government institutions, broadcast media, personal application and military in recent years.
Organosilicon, i.e., organosilicon compounds, are compounds which contain Si-C bonds and have at least one organic radical directly bonded to the silicon atom, and compounds in which an organic radical is bonded to the silicon atom via oxygen, sulfur, nitrogen, or the like are also conventionally used as organosilicon compounds. Among them, the polysiloxane composed of siloxane bond (-Si-O-Si-) as skeleton is the most numerous of the organosilicon compounds, the most deeply studied and widely used one, accounting for more than 90% of the total amount, the main chain of organosilicon is very flexible, and the intermolecular action force is much weaker than that of hydrocarbon, so that it has lower viscosity, lower surface tension, lower surface energy and higher film forming ability than that of hydrocarbon of the same molecular weight. This low surface tension and low surface energy are the main reasons for its versatile use: excellent performances of hydrophobicity, defoaming, stable foam, adhesion resistance, lubrication, glazing and the like.
Rotor formula unmanned aerial vehicle's rotor generally is made for carbon fiber material, has excellent mechanical properties, but when low temperature environment used, easily because rotor icing phenomenon leads to rotor aerodynamic layout to warp the inefficacy, and then leads to lift unstable, makes the condition that unmanned aerial vehicle is out of control take place. To solve this problem, a super-hydrophobic coating is usually sprayed on the rotor wing, and the super-hydrophobic characteristic is utilized to shorten the residence time of water drops on the coating surface, so that the water drops slide off from the material surface before freezing, thereby achieving the purpose of reducing or preventing freezing
Although the coating of the existing unmanned aerial vehicle rotor wing has the super-hydrophobic characteristic, the retention time of water drops on the surface of the coating can be shortened by utilizing the super-hydrophobic characteristic, so that the water drops slide off the surface of a material before being frozen, and the aim of reducing or preventing the freezing is fulfilled. However, despite the ice-over resistance that has been demonstrated, the coating structure is subject to wear, short life, and the coating does not have the ability to withstand irradiation, protect against ultraviolet light, and is subject to aging of the rotor.
