Embodiment 1

[0028] Such as figure 1 Middle: 1 is the anti-reflection coating layer on the front surface of the resin substrate, 2 is the hard coating layer on the front surface, 3 is the discoloration layer on the front surface, 4 is the polarizing layer, 5 is the UV adhesive layer, 6 is the resin substrate, 7 8 is the back surface color-changing layer, 8 is the hard coating layer on the back surface of the resin substrate, and 9 is the anti-reflection coating layer on the back surface.

[0029] Red: yellow: blue = 2:5:3 is adjusted to gray pigment, and then adsorbed on PVA to form a 30% transparent polarizing film. Then use protective film, release film, pressure-sensitive adhesive, double-layer TAC or PET to form and process into 4base finished color-changing polarizing film;

[0030] Clean and dry the 4base resin substrate, then spin-coat the front surface of the resin substrate with UV adhesive, and then paste a 4base polarizing film layer on the front surface of the lens, and mark t...

Abstract

The invention discloses a manufacturing technology of a multi-layer composite color-change polarizing resin lens for the interior of a vehicle. The technology mainly comprises special treatment for aresin polarizing film and a pasting process. The polarizing film with the same curvature is pasted to the surface of the resin hardened lens, the polarizing resin lens is marked according to a polarizing assembly line, an automatic hardening machine is used for dip-coating a color-change layer on the front surface of the lens, a surface hardened layer is added, then curing is performed, and the cured lens is placed in a vacuum film coating machine for film coating. The lens produced through the technology is fashionable and practicable.

Description

technical field [0001] The invention relates to the field of manufacturing optical resin lenses, in particular to a manufacturing process of a multi-layer composite color-changing polarized resin lens for interior use. Background technique [0002] Resin polarized lenses have attracted more and more attention in recent years. They are not only beautiful and fashionable, but also can effectively protect the eyes. Polarizing film has unique optical properties, which can effectively filter the glare of the sun in the same direction on the water, land or snow, suitable for sea activities, skiing, driving or fishing. [0003] At present, in the production process of polarizers, the manufacturing process of polarizing film is very important, which can be divided into dry method and wet method, and the process of using wet method is relatively stable, and the performance of the formed polarizing film is relatively excellent. The main role of polarized light is the effect of the dy...
