The invention relates to the technical field of functional materials and
surface engineering, and particularly provides a photo-thermal super-hydrophobic anti-
icing and deicing
coating with excellent durability and a preparation method of the photo-thermal super-hydrophobic anti-
icing and deicing
coating. The method comprises the following steps:
coating the surface of a pretreated base material with
epoxy resin to obtain an
epoxy resin layer;
silicon carbide particles are embedded into the
epoxy resin layer through electrostatic sand planting, an armor layer is obtained, and then a curing reaction is carried out; and spraying a modified
titanium nitride nanoparticle dispersion liquid on the surface of the cured armor layer, and
drying to obtain the photo-thermal super-hydrophobic anti-
icing and deicing coating with excellent durability. The surface of the coating has a high
water contact angle (CA) of 164 + / -1.6 degrees, a low
water sliding angle (SA) of 1.6 + / -0.5 degrees and a high
sunlight absorptivity of 0.988, and the coating can bear 1000 times of
adhesive tape stripping tests, 50 times of
abrasive paper abrasion tests under the pressure intensity of 3 kPa, seven days of
ultraviolet lamp
irradiation with the intensity of 20 W and 150 DEG C high-temperature stability tests.
