Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] see figure 1 , the present invention provides a technical solution: a spin-coating production process for photochromic lenses, comprising the following steps:

[0033] S1: Lens cleaning: Put the color-changing lens to be spin-coated in the washing machine, turn on the washing machine switch, and wash for 5-10 minutes. After cleaning, take out the lens, check the quality of the lens, and record the quality status. If the cleaning quality is qual...

Abstract

The invention discloses a spin coating production technology of a photochromic lens, and belongs to the technical field of lens production. The spin coating production technology comprises the following steps of, S1, cleaning the lens; S2, drying the lens; S3, cooling the lens; S4, preparing the spin coating solution; S5, mounting the lens; S6, carrying out primary spin coating on the lens; S7, carrying out secondary spin coating on the lens; S8, drying the lens; S9, taking out and cured the lens; and S10, carrying out quality detection. The lens is cleaned through an ultrasonic cleaner, the surface of the photochromic lens is thoroughly cleaned, so that a good foundation is laid for the subsequent soaking technology; and the pre-coated layer infiltrating by the primary spin coating not only makes the surface layer of the lens have very good adhesion force, but also makes excellent adhesion force to be generated between the surface layer and the silicon hardening liquid of the secondary spin coating, so that the hardening effect of the surface of the lens can be ensured, the wear resistance of the lens is improved, the phenomenon that the lens generates stripes during spin coatingis effectively avoided, color change is uniform, the impact resistance of the lens is improved, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of lens production, in particular to a spin-coating production process for color-changing lenses. Background technique [0002] Photochromic lenses, also known as "photosensitive lenses." The glass lens is added with silver halide, but the current mainstream is resin color-changing lenses. Chemical substances such as pyridoxine are added to acrylic resin lenses to make the originally transparent and colorless lenses turn into colored lenses when exposed to strong light. , for protection, so it is suitable for both indoor and outdoor use. [0003] At present, the methods used in the manufacture of color-changing sheets in China mainly include thermal infiltration method, substrate method and spin coating method. Among them, the thermal infiltration method is to add the discoloration agent with the adhesive agent into the thickener to form a discoloration coating, and immerse the finished product, such as th...
