Abstract

The invention relates to the technical field of optical resin materials, and discloses a sports protective lens resin monomer, a preparation method and a production system thereof, and the sports protective lens resin monomer comprises the following components by weight: 40-50 parts of diallyl isophthalate, 5-10 parts of trimethylolpropane acrylate, 15-20 parts of 4, 4 '-dimercaptodiphenyl sulfide methyl methacrylate, 15-25 parts of styrene and 8-12 parts of dibenzyl fumarate. The resin monomer material prepared by the method has the advantages of high refractive index, low dispersion, high hardness, high impact strength and high durability so that the sports protective lens produced by taking the resin monomer material as a raw material has strong drop resistance, impact resistance and impact resistance, and the lens material is not easy to corrode and is long in service life, and the use requirements in different sports scenes can be met.

Description

technical field [0001] The invention relates to the technical field of optical resin materials, in particular to a sports protective lens resin monomer, a preparation method and a production system 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 easy processing and molding, good film-forming properties, stamping resistance, light weight, and good coloring. Medium and high refractive index optical resin lenses are favored by users for their unique advantages such as high light transmittance, UV protection, and ultra-thin. At present, with the enhancement of people's fitness awareness, exercise and fitness have become one of the daily activities, and many of these people are nearsighted or need to be equipped with sports protective lenses according to the type of exercise, so sports protective lenses have b...
