Embodiment 1
[0028] A wire insulation coating of the present invention, specifically a two-component fast self-curing wire insulation coating, comprising A component and B component, A component is composed of isocyanate MDI 50 and polyether polyol N220, isocyanate MDI 50 and poly The mass ratio of ether polyol N220 is 50:50, component B consists of amino-terminated polyether D 2000, chain extender E100, porous Al 2 o 3 Powder and room temperature vulcanized silicone rubber, amino-terminated polyether D 2000, chain extender E100, porous Al 2 o 3 The mass ratio of powder and RTV silicone rubber is 60:25:10:5.
[0029] In this example, 02 o 3 The particle size of the powder is ≤100 microns, and the average particle size is 50 microns.
[0030] In this embodiment, room temperature vulcanized silicone rubber is filled in the voids of the porous metal oxide powdery filler, and the voids include the porous structure of the porous metal oxide powdery filler and the particle gaps of the porous...
Embodiment 2
[0035] A method for electrically-charging coating wire insulating coating of the present invention, using the wire insulating coating prepared in Example 1, the construction process is as follows: the wire insulating coating is carried by a drone, and the coating construction is carried out on the transmission wire by brushing .
[0036] In this embodiment, the UAV adopts DJI T20, and the UAV is equipped with an automatic hovering device (high-precision hovering device or laser guidance device) and coating equipment. And coating equipment a total of 20 kg. The UAV can fly directly above the wire and keep a constant distance from the wire through the existing spatial coordinates of the wire, or through its own laser guidance device, and can also provide the propulsion device and control for the storage tank of the insulating coating in the coating equipment. The device provides electric energy, and can also set the starting point and end point of the live coating construction ...
