TRANSPARENT HYDROPHOBIC WEAR-RESISTANT COATING AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2019/080287

A1

A transparent hydrophobic wear-resistant coating and a preparation method therefor. The transparent hydrophobic wear-resistant coating is composed of an epoxy resin layer and a low-surface-energy fluorine-containing layer which are arranged in sequence from top to bottom. The preparation method therefor comprises: (1) blending epoxy resin and a curing agent into an organic solvent, and carrying out ultrasonic treatment to obtain a coating solution, the total content of the epoxy resin and the curing agent being 0.001-5wt%; by adopting a dip-coating method for a substrate material, uniformly adhering the coating solution to the surface of the substrate material, and taking out and curing to obtain the epoxy resin layer; and (2) preparing the low-surface-energy fluorine-containing layer: coating the epoxy resin layer with the fluorine-containing solution, and drying to obtain the transparent hydrophobic wear-resistant coating. The coating is equivalent to glass in transparency, the surface contact angle is 102° or above, and the hydrophobicity of the coating is controllable; the coating has excellent mechanical strength and bonding property and is convenient for large-scale industrial production.
