Problems solved by technology

Generally speaking, aircraft icing may occur at the leading edge of the wing, the tail, the leading edge of the engine intake, the windshield, the sensor head of the instrument, etc., and will cause great damage to the flight performance: icing not only increases The weight of the aircraft, and destroy the aerodynamic shape of the wing, so the resistance increases, the lift decreases, the maneuverability and stability decrease; especially when the instruments and instruments freeze, it will also lead to abnormal indications, and some aircraft components often Has a complex three-dimensional structure, which also increases the difficulty of heating curved surfaces
The icing of the blades of the wind turbine will change the frequency of the fan blades, and then change its dynamic response behavior, seriously affecting the efficiency of the generator; the icing of the high-cold line of the high-speed rail will also seriously affect the operation safety of the high-speed rail
[0003] Traditional electric heating anti-icing is one of the most widely used technologies in traditional anti-icing technology, but the traditional electric heating method is to arrange resistance wires inside the substrate, the heat generated by the resistance wires is transferred to the outer surface through the body material, and the energy utilization At the same time, the

Abstract

The invention relates to a preparation method of an electric heating anti-icing coating capable of being used for a three-dimensional complex curved surface. The electric heating anti-icing coating capable of being used for the three-dimensional complex curved surface comprises a bottom layer electrode layer, a middle heating layer and a top layer electrode layer; and the preparation method comprises the steps: preparing a bottom layer material with conductivity on the surface of a three-dimensional curved surface base material, and forming a bottom layer electrode layer; preparing an intermediate heating layer material with conductivity, the middle heating layer material comprising conductive particles, a polymer matrix, a diluent and a dispersing agent; spraying the middle heating layermaterial on the surface of the bottom electrode layer to form an intermediate heating layer; and preparing a top-layer material with conductivity on the surface of the intermediate heating layer to form a top-layer electrode layer. The prepared electric heating anti-icing coating can be suitable for ice prevention and removal of complex components of airplanes.

Description

technical field [0001] The invention relates to the field of process preparation, in particular to a method for preparing an electrically heated anti-icing coating that can be used on three-dimensional complex curved surfaces. Background technique [0002] Aircraft icing refers to the phenomenon that when an aircraft flies in the atmosphere, a layer of ice accumulates on the surface of its components. Generally speaking, aircraft icing may occur at the leading edge of the wing, the tail, the leading edge of the engine intake, the windshield, the sensor head of the instrument, etc., and will cause great damage to the flight performance: icing not only increases The weight of the aircraft, and destroy the aerodynamic shape of the wing, so the resistance increases, the lift decreases, the maneuverability and stability decrease; especially when the instruments and instruments freeze, it will also lead to abnormal indications, and some aircraft components often It has a complex ...
