Electric-heating anti-icing coating and preparation method thereof

Abstract

The invention provides an electric-heating anti-icing coating. The electric-heating anti-icing coating is structurally formed through the steps that firstly, an insulating coating is sprayed onto a substrate, so that insulation and heat insulation from the substrate are achieved; secondly, an electrode is manufactured on the insulating coating so that heating can be more uniform; thirdly, electric-heating paint is sprayed onto the electrode; and finally, a protective coating is sprayed onto the outermost layer. A preparation method of the electric-heating anti-icing coating comprises the following steps that firstly, a coupling agent is placed on a table concentrator for hydrolysis, so that hydrolysate is obtained; and heating coating filler is added into the hydrolysate to be soaked and modified and then is dried, so that modified heating coating filler is obtained; secondly, a heating coating base material is placed in a beaker to be diluted with xylene, and dispersing agents such as trinitrobenzene are added, so that a heating coating base body diluent is obtained; and thirdly, the heating coating filler is added into the heating coating base body diluent, evenly stirred and placed into an ultrasonic cleaning machine for ultrasonic dispersion for 15 minutes, so that the required electric-heating coating is obtained. According to the coating, energy consumption is low, heating is uniform, the manufacturability is good, and the purpose of preventing and removing ice can be achieved.
