Problems solved by technology

These lenses are prone to edge cracking and delamination during subsequent processing and wearing, resulting in scrapped processing, loss of polarizing performance, and fragile lenses
Furthermore, due to the binding force, polarized lenses can only be used with full-frame frames, which are limited to a certain extent in terms of wearing options.

Abstract

The invention belongs to the technical field of visual-optic materials and relates to polarizing resin lens, and especially relates to a high-binding-force and anti-impact resin lens composition, which is composed of, by weight, 25-60 parts of isocyanate, 40-75 parts of polyol, 0.02-2 parts of an ultraviolet absorbent, 0-0.5 parts of an internal demolding agent, 0-0.005 parts of a toner, and 0.005-0.2 parts of a catalyst. The invention also discloses a method of producing a high-binding-force and anti-impact polarizing resin lens from the composition. The composition is composed of, according to the formula, the isocyanate, polyol, catalyst, ultraviolet absorbent, internal demolding agent and toner, wherein a polarizing film is formed from a single-layer or multi-layer polyvinyl alcohol-based composite film material. The polarizing resin lens supplies clear view, is good in safety, and has strong binding force between the film layer and the resin base material. The polarizing resin lens can adapt mounting demand on whole-series glasses frames, and also satisfies demands on safety, comfort and durability of glasses lens.

Description

technical field [0001] The invention belongs to the technical field of optics materials, and relates to a polarized resin lens, in particular to a resin lens composition with high binding force and impact resistance and a preparation method for a polarized lens. Background technique [0002] With the continuous improvement of people's quality of life, polarized sunglasses are becoming more and more popular, but due to the production process and the characteristics of polyvinyl alcohol (PVA), nearly 80% of the polarized lenses on the market are composite polarized films. , it is necessary to apply glue to ensure the tight combination of the polarizing film and the substrate. [0003] At present, the common planar polarizing resin lens is a composite film of triacetate cellulose (TAC) or polycarbonate (PC) and polyvinyl alcohol (PVA) polarizing film; Ester (ADC) is used as the base material, PVA polarizing film and PVA / TAC / PC composite film coated with glue film are co-polyme...
