有機－無機混成矽氧烷水膠組成物及其製備方法和應用

Abstract

本發明揭露一種有機-無機混成矽氧烷水膠組成物及其製備方法和應用，是利用末端羥基之矽氧烷巨分子與無機矽烷偶聯劑做為原料，在加溫與鹼性環境下進行反應，待其形成澄清透明溶液後，直接與親水性之2-羥基乙基丙烯酸甲酯和甲基丙烯酸進行混合，形成可光聚合之有機-無機混成矽氧烷水膠組成物，而不會造成相分離的情況，且過程中無需添加稀釋劑，也不需有機溶劑處理，再經紫外光加熱固化後所得之有機-無機混成矽氧烷水膠兼具高透光性、尺寸穩定性，未來可廣泛應用於光學、醫材及塗料工業上。 An organic-inorganic hybrid siloxane hydrogel composition, and manufacturing method and using the same are provided. The siloxane macromolecule having terminal hydroxyl groups and the inorganic silane coupling agent are utilized as the material, to react in the heating and alkaline condition to form a clear and transparent solution. The solution is mixed with the hydrophilic 2-hydroxyethyl acrylate and methacrylic acid to form the photopolymerizable organic - inorganic hybrid silicone hydrogel formulation without phase separation. The diluent and the organic solvent treatment are not required. After the formulation by the UV heat curing, the hydrogel is obtained with high transmittance and dimensional stability, and may be widely applied in ophthalmic, medical device and coating industry in the future.
