Technical Field

The invention belongs to the technical field of film material preparation, and particularly relates to a preparation method for coating a film on the surface of a substrate such as glass and the like and enabling the substrate to have excellent wear resistance and antifogging property.

Background

People often come into contact with glass in everyday life and production, such as windshields of vehicles, rear-view mirrors, bathroom mirrors, windows of buildings, solar panels, and the like. However, under certain temperature and humidity conditions, water vapor in the air can be condensed together to form tiny water drops on the glass surface, so that the fogging phenomenon can easily occur, and the refraction and reflection phenomena of light can be caused due to the existence of the small water drops. Under some circumstances, the atomizing phenomenon can cause certain influence to people's life and production, for example can influence vehicle driver's sight, leads to can't see through glass and sees the object in the place ahead clearly to cause serious harm to driving safety.

The current methods for eliminating the atomization phenomenon mainly comprise two methods: the first is that from the thermodynamic point of view, the water droplets condensed from water vapor under specific conditions are evaporated in a short time by the heat energy. The second method is to treat the surface of the substrate from the surface chemical composition and structure of the material, so as to change the chemical composition and structure of the glass surface, thereby changing the wetting state of the glass surface and achieving the hydrophilic or hydrophobic antifogging effect. The heating method is used for achieving the anti-fog purpose, the time is often long, the practical performance is limited to a certain degree, and the heating device is complex to install, high in cost and not beneficial to large-scale application. Therefore, most researchers often consider changing the wettability of the substrate material, which can be started from two aspects, namely, hydrophilizing the surface of the material, rapidly and uniformly spreading the liquid on the solid surface, and forming a water film on the surface of the material by water drops, so that the phenomena of scattering and refraction of the water drops on the light are eliminated, and the anti-fog effect is achieved. On the other hand, the surface of the material is hydrophobized, the contact angle of water drops is increased, and the water drops fall off under the action of the gravity of the water drops, so that the antifogging effect is achieved. However, many hydrophobic or super-hydrophobic systems contain silicon, fluorine and other components, so that the adhesion capability of the materials is poor, the firmness is poor, and the fluorine-containing compounds pollute the environment to a certain extent.

Therefore, the research on the wear-resistant anti-fog film has a greater prospect, and for the application, the anti-fog film with certain wear resistance is prepared by a spin-coating method, the film forming property is good, the price is low, the anti-fog property is durable, and the light transmittance of the original glass is not influenced after the film is coated. CN 103664004B discloses an antifogging coating, a preparation method of the antifogging coating and antifogging glass, but the surface hydroxylation treatment modes are different, and the curing temperature ranges are different; the steps of hydroxylation, cross-linking and antifogging are required to be carried out in multiple steps. The solvent used in the invention is deionized water, so that the invention is more environment-friendly; and with the use of H₂O₂And concentrated H₂SO₄Compared with the method for hydroxylation by using the mixed solution, the method is safer and more effective by using oxygen plasma, has lower temperature range for curing and is more convenient to operate. CN 104086093B discloses an antifogging coating and a manufacturing method thereof, and antifogging glass compared with the invention, the pretreatment of common glass in the invention does not need physical polishing, and the operation is simpler and more convenient; organic solvents of acetone and tetrahydrofuran are not used, so that the method is more environment-friendly, and the heat treatment does not need to be carried out under a vacuum condition, so that the operation is convenient; besides glass and PC plates, the glass can also be applied to PET and PVC plates, and the application range is wider.
