Abstract

The invention relates to the technical field of chemical coatings, in particular to a plasma chemical vapor deposition nano super-hydrophilic anti-fog coating and a preparation method thereof. The method comprises the following steps that S1), cleaning is carried out on the surface of a base material; S2) activating is carried out on the surface of the base material; S3) a hydrophilic coating is prepared; and S4) a nano-deposition super-hydrophilic film is prepared; and deposition activation treatment is carried out on the hydrophilic coating, and the nano-deposition super-hydrophilic film isdeposited and adsorbed on the surface of the hydrophilic coating. The invention further provides the plasma chemical vapor deposition nano super-hydrophilic anti-fog coating prepared by the preparation method of the plasma chemical vapor deposition nano super-hydrophilic anti-fog coating, and the plasma chemical vapor deposition nano super-hydrophilic anti-fog coating has the characteristics of nopollution, safety and reliability, has excellent anti-fog, wear-resistant, water soaking-resistant, solvent-resistant and salt spray-resistant properties, and is long in service life. The nano-deposition super-hydrophilic film is a plasma chemical deposition nano hydrophilic film adsorbed on the outer surface of the hydrophilic coating.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a plasma chemical vapor deposition nanometer super-hydrophilic anti-fog coating and a preparation method thereof. Background technique [0002] Reflective products and waterproof products made of substrates such as glass and plastic, such as swimming goggles, diving goggles, and waterproof reflective mirrors for road traffic, are indispensable in people's daily life, work and production. [0003] However, during its use, fogging often occurs, which reduces the light transmittance and reflectivity of the substrate, affects the user's sight, brings inconvenience, and even causes danger. [0004] Anti-fog coating is a functional coating used to slow down or prevent the occurrence of fogging. Anti-fog coatings include hydrophobic and hydrophilic types. In the prior art, there are many researches on hydrophilic anti-fog coatings. Other special functions can also be obtain...
