Problems solved by technology

Due to the characteristics of PC, PA, PET, PMMA and other materials, it is difficult to combine well with the PVA polarizing layer, resulting in the injection molding production of polarizing lenses made of PC, PA, PET, PMMA and other materials. The fastness of the material is not good and it is easy to be layered; and due to the temperature resistance of the PVA polarizing layer, the polarizing layer is easy to burn and dissolve after injection molding, the polarizing performance is reduced, and the polarizing layer is discolored.
Resulting in increased costs, waste of resources and energy

Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer definition of the protection scope of the present invention;

[0030] The technical solution of the present invention is a manufacturing process of a hot-pressed optical film and a hot-pressed polarized lens. The manufacturing process steps are as follows:

[0031] S1. Mix 46% Polyurethane, 21% plastic rubber, and 25% fully oxidized petroleum resin according to the mass ratio, stir for 1.5 hours, then add 5.5% additives, stir for 0.5 hours; then add 1.0% antioxidant, stir for 0.5 hours ;Finally add 1.5% anti-permeability agent and stir for 2 hours to obtain plastic;

[0032] S2. Select the required material film layer, and apply the plastic Figure 4 As shown, the required polarizing layer is comp...

Abstract

The invention discloses a hot-pressed optical film and a manufacturing process of a hot-pressed polarized lens thereof. The manufacturing process comprises the following steps: S1, preparing plastic glue; S2, selecting a required material film layer, coating the plastic glue between the film layer and a polarized film PVA (polyvinyl acetate) to compound as a required polarized layer; S3, laminating a layer of release film on an outer surface of the polarized film layer to protect the plastic glue at the outer layer; S4, performing buckling and shaping on the polarized film layer; and S5, performing hot-pressing on the bent and shaped film and a bottom plate made of different materials to obtain a hot-pressed polarized lens. The multi-material hot-pressed optical film and the hot-pressed polarized lens produced by adopting the process are good in fastness, strong in optical performance and hard to discolor; the energy source can be effectively saved, the resource loss is reduced, the production cost is reduced, and the production yield is improved.

Description

technical field [0001] The invention belongs to the field of optical materials, in particular to a manufacturing process of a hot-pressed optical film and a hot-pressed polarized lens. Background technique [0002] At present, the production of polarized sun lenses made of PC, PA, PET, PMMA and other materials is through pre-compositing of PVA polarizing layer with TAC, PC, PA, PET, PMMA and other materials, and then through high-temperature injection molding and film PC, PA, Made of PET, PMMA and other material lenses. Due to the characteristics of PC, PA, PET, PMMA and other materials, it is difficult to combine well with the PVA polarizing layer, resulting in the injection molding production of polarizing lenses made of PC, PA, PET, PMMA and other materials. The fastness of the material is not good and it is easy to delaminate; and due to the temperature resistance of the PVA polarizing layer, the polarizing layer is easy to burn and melt after injection molding, the pol...
