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. The parts by weight of each component are: 40-50 parts of diallyl isophthalate, 5-10 parts of trimethylolpropane acrylate, 15-20 parts of 4,4'-dimercaptodiphenyl sulfide dimethacrylate, 15-25 parts of styrene, 8-12 parts of dibenzyl fumarate share. The resin monomer material prepared by the present invention 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 using it as a raw material has strong drop resistance, impact resistance, Impact-resistant performance, and the lens material is not easy to corrode, has a long service life, and can meet its use requirements in different sports scenes.

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 has been increasing in the domestic and foreign glasses markets. 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...
