Problems solved by technology

[0004] At the same time, most lenses, especially high-end lenses, will have a layer of hydrophobic and oleophobic film deposited on them when they leave the factory. Shrinkage cavity phenomenon, so it is difficult to form an effective anti-fog film layer, and the ideal anti-fog effect cannot be achieved

Abstract

The invention discloses an antibacterial antifogging agent, and an antibacterial long-acting antifogging wet tissue prepared from the same. The antibacterial long-acting antifogging wet tissue is prepared from, by mass, 0.1-0.5% of a special film forming agent, 0.05-0.1% of an antibacterial agent, 0.01-0.05% of a chelating agent, 0.1-0.5% of alkyl glycoside, 0.01-0.1% of an emulsifier, 0.01-0.1% of a fluorocarbon surfactant, 0.01-0.1% of sodium chloride, 0.05-0.1% of citric acid, 10-40% of absolute ethyl alcohol, and the balance of water. The product prolongs the antifogging time to a great extent, and is suitable for various types of lenses.

Description

technical field [0001] The invention relates to the technical field of antibacterial and antifog products, in particular to an antibacterial antifogging agent and an antibacterial long-lasting antifogging wet wipe prepared therefrom. Background technique [0002] Transparent materials such as glass and resin play an important role in daily life and industrial production, but such transparent products (such as corrective glasses, sunglasses, ski / sports glasses, protective glasses, window glass, bathroom glass, etc.) Fog. Fogging is caused by the liquefaction and condensation of water vapor on the surface of the transparent substrate to form extremely fine water droplets. In daily life, the fogging phenomenon is more likely to occur in the following two scenarios: one is the transition from a cold environment to a warm environment (for example, in the cold winter, entering the room from the outside), and the other is the transparent substrate and relative humidity. Higher ho...
