Problems solved by technology

At present, the preparation of optical resins for the production of low refractive index lenses is very common, but the preparation technology of optical resin monomers for the production of medium and high refractive index lenses is still not very mature, although there are still some optical resins for medium and high refractive index lenses However, due to the raw materials used, the resulting resin lenses tend to have poor toughness, poor impact resistance, poorer chemical resistance than glass, and easy scratches and breaks on the surface. Improvement in various ways, thus increasing the manufacturing cost

Abstract

The invention relates to a high-toughness and impact-resistant resin eyeglass and a preparation method thereof; the resin eyeglass comprises the raw materials in parts by weight: 20-25 parts of dimethyl 1,4-benzenedicarboxylate, 20-25 parts of dimethyl 1,3-benzenedicarboxylate, 3-5 parts of allyl alcohol, 12-15 parts of an allyl ether phenolic resin, 12-15 parts of pentaerythritol tetrakis(2-mercaptoacetate), 8-10 parts of hexamethylene-1,6-diisocyanate, 8-10 parts of bismaleimide, 1.5-3 parts of a wear-resisting agent, 0.5-1.5 parts of a catalyst, and 0.5-1.5 parts of an internal mold release agent. While the resin eyeglass is ensured to have excellent refractive index, the chemical resistance is allowed to be greatly improved, the toughness and impact resistance of the prepared resin eyeglass can be greatly improved, scratches and a breaking phenomenon are not easily generated, and the service life is facilitated to be greatly extended.

Description

technical field [0001] The invention relates to the technical field of resin lenses, in particular to a high-toughness and impact-resistant resin lens and a preparation method thereof. Background technique [0002] In recent years, the demand for optical resin lenses in the domestic and foreign glasses markets has been increasing. Compared with glass lenses, resin lenses have the advantages of light weight, good dyeing performance, and easy processing. Medium and high refractive index optical resin lenses are more transparent High efficiency, UV protection, ultra-thin and other unique advantages are favored by users. Generally, in the lens industry, the refractive index is above 1.60 as the high refractive index, the refractive index is 1.56 as the medium refractive index, and the refractive index is below 1.56 as the low refractive index. At present, the preparation of optical resins for the production of low refractive index lenses is very common, but the preparation tech...
