Problems solved by technology

The domestic industry started late and the starting point of technology is low. In recent years, domestic production plants have imported high-refractive resin monomers from abroad to polymerize and process high-refractive optical resin lenses. Most of the high-refractive optical resin lenses produced belong to acrylic (methacrylic acid) series. , high refraction optical resin lenses made of acrylic resin materials, poor dyeing, high dispersion, poor impact resistance, not as good as super impact resistant high refraction optical resin lenses

Abstract

The invention relates to an impact resistance optical resin glasses and a manufacturing method thereof, which is characterized in that optical resins materials consist of materials which have A component and B component, and the weigh percentage ratio of the two components is that: A component: B component = 40-50: 60-50, wherein, the A component is prepared by bi-isocyanic acid hexyl ester with the weigh percentage ratio 44-56 percent and multivariate isocyanate-group compounds which have a benzene ring and have the weigh percentage ratio of 56-44 percent; the B component is prepared by the reaction products of pentaerythritol and 3-sulfhydryl-acrylic acid with the weigh percentage ratio 85-95 percent and tetrathio-pentaerythritol with the weigh percentage ratio 15-5 percent; a catalyst adopts double dodecyl halide stannous: R-D2Sn-R; and the addition amount of the catalyst is 0.05-0.12 percent of the total weight of the A and the B components. A computer temperature control curing oven which is provided with a quick cooling device is adopted by the invention, thus guaranteeing the optical precision and the optical quality of the glasses, well and uniformly mixing the raw materials and greatly improving the qualification rate of the glasses.

Description

technical field [0001] The invention relates to a manufacturing process of an optical resin lens, in particular discloses a high-refractive-index super-impact-resistant optical resin lens and a manufacturing method thereof. Background technique [0002] The optical resin lens production industry has developed rapidly in China and has become a new type of industry in China. High-refractive optical resin lenses are popular all over the country. They have the properties of light texture, compact structure, good optical performance, thin lenses and effective anti-ultraviolet rays. The domestic industry started late and the starting point of technology is low. In recent years, domestic production plants have imported high-refractive resin monomers from abroad for polymerization and processing to make high-refractive optical resin lenses. Most of the high-refractive optical resin lenses produced belong to acrylic (methacrylic acid) series. , high refraction optical resin lenses m...
