Abstract：In order to solve technical problems about partial conduction on the surface of equipment optical lens,a series of process method which adapted to the partial surface of equipment optical lens was screened out,the paint category of shielding film coating process was determined,the thickness of shielding film was 120 μm,the curing temperature was 93 ℃,the curing time was 35 min.The shielding film could protect optical lens based on effective isolation between conductive surface and sulfuric acid anodic oxidation solu-tion through shielding film.It could realize the purpose of protecting the conductive surface of optical lens, and satisfy the request of the particular use of partial conduction and partial blackening after sulfuric acid anodic oxidation on the surface of equipment optical lens.
