Transparent super-hydrophobic coating as well as preparation method and application thereof
The invention belongs to the technical field of hydrophobic coating materials, and provides a transparent super-hydrophobic coating as well as a preparation method and application thereof. Only one layer of thin hydrophobic silicon dioxide (with the thickness of 300-500 nm) is embedded in the surface of the polyurethane layer on the surface of the transparent super-hydrophobic coating, so that the white modified silicon dioxide has no influence on the transparency of the coating; meanwhile, the curing temperature in the preparation method is controlled to be 120-180 DEG C, and compared with normal-temperature slow curing, polyurethane shows high transmittance. And the modified silicon dioxide is used, so that the coating has super-hydrophobicity, and further has self-cleaning capability.
本发明属于疏水涂层材料技术领域，提供了一种透明超疏水涂层及其制备方法和应用。本发明的透明超疏水涂层的表面只有一层薄薄的疏水二氧化硅(厚度为300～500nm)镶嵌在聚氨酯层表面，使得白色改性二氧化硅对涂层的透明度不会有影响；同时，控制制备方法中的固化温度为120～180℃，相比常温缓慢固化，使得聚氨酯呈现高透过率。改性二氧化硅的使用，使得涂层具备超疏水性，进而具有自清洁能力。
