Coating antifog eyeglass and preparing method thereof

Abstract

The invention discloses a coating antifog eyeglass and a preparing method thereof. The coating antifog eyeglass comprises a substrate layer, an upper film antifog coating arranged above the substratelayer and a lower antifog coating arranged below the substrate layer, wherein the upper antifog coating comprises an upper corrosion crosslinking layer and an upper antifog layer, the upper film antifog coating is alternately formed by an upper corrosion crosslinking layer and an upper antifog layer, the lower antifog coating comprises a lower corrosion crosslinking layer and a lower antifog layer, and the lower antifog coating is alternately formed by a lower corrosion crosslinking layer and a lower antifog crosslinking layer. The coating antifog eyeglass has the advantages that since the antifog coatings provided with the corrosion crosslinking layers and the antifog layers are arranged on the upper surface and the lower surface of the substrate, through a unique process of the eyeglass,a coating material is prepared to soak the eyeglass, so that the surface hardness of the eyeglass is increased, the eyeglass is highly hydrophilic, the certain transparency of the surface of the eyeglass is maintained, then the antifog effect is achieved, a layer of uniform hydrophilic film is further formed, scattering of light is reduced, the transparency of the surface of the eyeglass is guaranteed, and thus a better antifog effect is achieved.

Description

technical field [0001] The invention relates to an antifog lens, in particular to a coated antifog eyeglass lens and a preparation method thereof. Background technique [0002] The original resin lens is particularly prone to fogging in environments with temperature differences. Fogging of eyeglass lenses means that the water vapor in the air in the environment with large temperature differences reaches a saturated state, and condenses on the surface of the lens to form tiny droplets to form fog. On the one hand, the light is refracted and scattered, which changes the optical properties of the lens surface, affects the light transmittance, and causes the opacity of the lens. The surface corrosion problem brings a lot of inconvenience to life and brings serious harm to driving safety. [0003] Foreign countries began research on anti-fog glass in the 1960s. But there is no substantive breakthrough in the lens industry and the actual application is still far away. Under nor...

Problems solved by technology

Under normal circumstances, the common anti-fog measures for lenses on the market are as follows: 1. Spray a layer of chemical anti-fog agent or other surfactants on the surface of the lens; 2. Use anti-fog lens cloth to wipe; The method is to maintain the hydrophilic effect, but the anti-fog time is short, and it is necessary to spray the anti-fog agent repeatedly on a regular basis and repeatedly use the more expensive anti-fog mirror cloth to wipe, and it brings chemical smell and inconvenience, wear resistance and Poor durability has caused many users troubles
