Optical lens coating film composition and processing method thereof

Abstract

The invention discloses an optical lens coating film composition. The optical lens coating film composition is characterized by being prepared from the following raw materials in parts by weight: 60-80 parts of polysiloxane, 10-20 parts of organic silicon resin, 6-8 parts of nano-titania, 6-8 parts of nano-silica, 5-7 parts of silica sol, 2-4 parts of a coupling agent, 2-4 parts of a flatting agent, 3-5 parts of an adhesion promoter, 6-8 parts of fluorosilicone oil and 10-20 parts of oleic acid. The optical lens coating film composition has the beneficial effects that the technological process is simple, the formula is reasonable in selection, a relatively hard wax membrane is prepared from relatively precise raw materials, the surface of a lens is directly coated, a relatively hard protective film is formed on the surface of the lens, the light transmittance of the lens is not affected, interference of external stains can be effectively blocked, and the optical lens coating film composition is significant in effect and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of optical lens processing, in particular to an optical lens coating composition and a processing method thereof. Background technique [0002] A lens is an optical device that receives an optical object on a camera and adjusts it to achieve optical imaging. A lens is usually a lens group composed of one or more pieces of optical glass, and the basic unit is a concave lens, a convex lens, or a combination thereof. Modern camera lenses also use aspheric mirrors, which are divided into optical glass ground aspheric mirrors and plastic pressed aspherical mirrors. Under the condition that the imaging quality is basically the same, the manufacturing cost and service life are quite different. In theory, a simple convex lens is a lens, but in practical applications, the lens requires a combination of various lenses to correct optical distortion. [0003] Lens is one of the most important optical components in im...

Problems solved by technology

[0003] Lens is one of the most important optical components in imaging equipment, such as cameras, projectors and video cameras, etc., and lenses are all essential components. However, since lenses are directly exposed to the air, in actual use, it is very difficult to It is easy to produce stains, so regular cleaning and maintenance must be carried out. However, due to long-term cleaning and maintenance, it will cause actual lens damage and equipment damage. Therefore, how to protect the lens for a long time is an important topic of current research.
