| titleOfInvention | A method of preparing epoxy acryl based optical material |
| abstract | The present invention relates to a resin composition for an epoxy acrylic medium-refractive optical lens and a method for manufacturing the same, in particular, a high-quality epoxy acrylic medium-refractive optical lens resin having a good Abbe number in the range of 1.53 to 1.58, transparency, compressive strength, light weight, and heat resistance. It relates to a composition and a method of manufacturing the same. In the present invention, 30 to 70% by weight of bisphenol A epoxy acrylate compound represented by the formula (1) in the total composition, 3 to 30% by weight of methyl methacrylate and 5 to 50% by weight of reactive diluent epoxy acrylic medium refractive optical lens Dragon resin composition is provided. According to the present invention, it is possible to manufacture a high quality medium refractive optical lens having excellent Abbe number, transparency, compressive strength, light weight, and heat resistance without increasing the production cost of the existing medium refractive lens using an epoxy acrylic monomer. The epoxy acrylic medium refractive optical material manufactured according to the present invention can be widely used in various fields by replacing the existing medium refractive optical material. |
