Optical adhesive composition and product thereof

The invention relates to the technical field of optical cement, and provides an optical cement composition and a product thereof. The optical adhesive composition is prepared from the following monomer components in percentage by weight: 45 to 74 percent of acrylate soft monomer, 20 to 40 percent of hydroxyl-terminated polyethylene glycol acrylate macromonomer, 5 to 10 percent of cross-linking monomer and 1 to 5 percent of nitrogen-containing heterocyclic ring monomer, wherein the total amount of monomers of the composition is 100 percent. The optical cement has lower glass transition temperature and lower low-temperature modulus, so that the prepared optical cement product has the advantages of high bonding strength, good folding performance, small difference between high temperature and low temperature and the like. 本发明涉及光学胶技术领域，提供了一种光学胶组合物及其制品。该光学胶组合物，以所述组合物组成单体总量为100%计，包括以下单体组分：丙烯酸酯软单体45~74%、端羟基聚乙二醇丙烯酸酯大分子单体20~40%、交联单体5~10%、含氮杂环单体1~5%。该光学胶具有较低的玻璃化转化温度和较低的低温模量，使得制备的光学胶制品具有粘结强度高、折叠性能好以及高低温差异小等优点。
