Abstract
The invention discloses high borosilicate optical lens glass and a preparation process thereof, and relates to the technical field of glass surface treatment.The preparation process of the high borosilicate optical lens glass comprises the following steps that raw materials are mixed, melted, formed and subjected to heat treatment, and the high borosilicate glass is obtained; and carrying out etching and sol coating to form an antireflection layer so as to obtain the optical lens glass. The preparation method comprises the following steps: preparing an antireflection layer on the surface of high borosilicate glass through etching and sol coating, during sol coating, firstly loading fluorine-containing POSS on the surface of the glass by utilizing hydrosilane to form a POSS modified layer, then preparing hollow silicon dioxide sol by taking a polymer of polyvinylpyrrolidone and fluorine-containing POSS as a template, and curing after coating to form a composite structure. The surface refractive index of the glass is greatly reduced, light reflection can be reduced, the light transmittance and definition of the glass are improved, and the visual experience is more comfortable and natural.
