Abstract

The invention discloses a preparation method of an antifogging coating solution for spectacle lenses, and relates to the technical field of lens protection solutions. The preparation method of the antifogging coating solution for the spectacle lens comprises the following steps: adding the nonionic surfactant into the diluent, performing stirring, adding the anionic surfactant after uniformly stirring, and continuously performing stirring until uniform mixing; heating the mixed solution, skimming floating foam on the upper layer of the mixed solution after heating, performing standing, performing cooling to room temperature, adding the mixed solution into a stirrer, adding the aloe extract into the stirrer, performing stirring, adding sodium ascorbyl phosphate, continuously performing stirring, finally adding the antibacterial agent, and performing stirring again to obtain the antifogging coating solution. The solution prepared by the method has good lens antifogging performance, can effectively reduce the influence of lens fogging on a user in the use process, has practicability, and can meet the requirements of the user.

Description

technical field [0001] The invention relates to the technical field of eyeglass protection liquid, in particular to a preparation method of an anti-fog coating solution for eyeglass lenses. Background technique [0002] Lens fogging is a natural phenomenon. When the lens is in an indoor and outdoor environment with a large temperature difference, the water vapor in the air will quickly condense on the lens and form tiny water droplets. When the light shines on the surface of these small water droplets, Scattering will occur, which will reduce the light transmittance of the lens and blur the vision. This is the phenomenon of lens fogging. [0003] In order to reduce the impact of lens fogging on users, various anti-fog coating liquids for spectacle lenses have appeared on the market, but so far, no anti-fog coating solution for spectacle lenses with good anti-fog effect has been found The coating solution can completely anti-fog the lens, and the user's anti-fog needs have n...
