Abstract

The invention discloses a coated 3D (three dimensional) resin lens and a preparation method thereof. The preparation method comprises the following steps: firstly, mixing nano titanium particles witha surfactant to obtain modified nano titanium particles; secondly, mixing the nano titanium particles with an alcohol solvent according to the mass ratio of (1 to 3.5) to 100, reacting at the temperature of 20 to 50 DEG C for 15 to 20 minutes to obtain a solution containing titanium oxide nanoparticles; thirdly, mixing the solution containing the titanium oxide nanoparticles, ammonium acetate, glycerol, ammonium citrate and hardening liquid, reacting at the temperature of 30 to 55 DEG C for 10 to 20 minutes to obtain coating liquid; fourthly, putting a resin lens into the coating liquid for soaking and then taking out, successively carrying out first-time baking and second-time baking to obtain the coated 3D resin lens. The coated 3D resin lens has the advantages that the problems of insufficient wear resistance and high possibility of generating scratches on the surface after long-time use in the existing resin lens are solved.

Description

technical field [0001] The invention relates to the field of VR equipment, in particular to a coated 3D resin lens and a preparation method thereof. Background technique [0002] Since the birth of resin lenses, manufacturers have been pursuing how to further improve the performance of light and transparent resin lenses. However, the quality of high-quality lenses is not only determined by the lens material, but also its surface coating plays a vital role. The wear resistance of current resin lenses is not enough, and the surface is prone to scratches after long-term use. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a coated 3D resin lens with better wear resistance and less prone to scratches after long-term use and its preparation method. Contents of the invention [0004] The purpose of the present invention is to provide a coated 3D resin lens and its preparation method, which solves the problem that the current resin le...
