Abstract

The invention relates to a super-hydrophobic nano-ceramic material and a coating layer formed by the super-hydrophobic nano-ceramic material, belonging to the technical field of coating layer materials. The super-hydrophobic nano-ceramic material mainly contains the following components in parts by weight: 60-80 parts of nano-titanium dioxide powder, 8-25 parts of nano-hexagonal boron nitride powder, 2-10 parts of nano-aluminum oxide powder, 2-8 parts of nano-zirconium oxide powder, 5-10 parts of silicon dioxide powder, 2-6 parts of super-hydrophobicity lead tungstate nanocrystallines and 1-10parts of a modifying agent. The coating layer is prepared by coating the surface of a base material with the super-hydrophobic nano-ceramic material. The coating layer prepared from the super-hydrophobic nano-ceramic material has excellent super-hydrophobicity and chemical stability, good durability, mechanical property and mechanical property and high surface hardness, has strong bonding force with the base material and is capable of bearing relatively large load, the super-hydrophobicity can be maintained for a long time, the surface structure is unlikely to be broken by an external force,and the service life is long.

Description

technical field [0001] The invention relates to a superhydrophobic nano-ceramic material and a coating formed therefrom, belonging to the technical field of coating materials. Background technique [0002] Based on the analysis and theoretical research of superhydrophobic phenomena in nature, such as lotus leaves, water strider legs, and butterfly wings, researchers have developed a variety of superhydrophobic nanomaterials and bionic surfaces. The goal of the design and development of superhydrophobic nanomaterials is not only to imitate the functional structure of organisms, but more importantly, to prepare superhydrophobic surfaces with adjustable components and structures. Superhydrophobic surface nanomaterials have a special micro-nano structure, so they have a series of excellent properties such as hydrophobic self-cleaning and anti-pollution, and have broad applications in many fields such as biological antifouling, transportation and navigation, medicine, national de...

Problems solved by technology

However, due to the limitations of current technology and development costs, there are not many actual industrialization and commercialization

First of all, the durability and aging resistance of the surface coating, the surface performance is not ideal, such as low strength, poor durability, many super-hydrophobic structures lose their self-cleaning function in a short period of time due to weak or easy to be damaged

Secondly, the high cost of superhydrophobic nanomaterials, complex production process, large-scale equipment, and harsh preparation conditions make it difficult to adapt to the requirements of large-scale industrial production.
