Problems solved by technology

Optical resins are divided into thermoplastic resins and thermosetting resins. Thermoplastic resins such as polycarbonate (PC) are mainly used for sun lenses and partial corrective lenses. The advantages are fast molding and low molding cost. The disadvantage is relatively large internal stress. , general optical performance
Thermosetting resins such as polymethyl methacrylate (PMAA), polyurethane (PU) and polydiallyl diglycol carbonate (CR-39) have the advantages of good optical properties and small stress, but molding requires 20 - Molding time ranging from 40 hours, the polymerization time is relatively long
In order to solve the problem of comparison of curing time in the above-mentioned thermosetting resin manufacturing process, the manufacturing method of ultraviolet light curing resin with a refractive index of 1.56 and its resin lens manufacturing method were developed

Description

【Technical field】 [0001] The invention relates to the technical field of resin lenses, in particular to a resin lens with a refractive index of 1.56 cured by ultraviolet light and a production method thereof. 【Background technique】 [0002] Before the 1930s, the main material in the optical field was optical glass, with nearly 240 types and a refractive index ranging from 1.4 to 2.8, with a wide range of choices. As a wearing product, spectacle lenses have relatively high requirements on specific gravity and impact resistance. However, most optical glass has a large specific gravity and is easily broken. Compared with optical glass, optical resin has the advantages of light weight, impact resistance and easy processing and molding. Once launched, it quickly replaced optical glass and became the mainstream product of spectacle lenses. The development and research of optical resin abroad began in the 1920s, and dozens of optical resins with different specifications have been...
