在基础理论研究与关键技术突破的基础上，进行光学聚氨酯 的产业化攻关，系统优化集成了 1.67 聚氨酯镜片产业化示范 线。产业化示范生产线基本建成，产能达到 1000 万片。在 短流程工艺优化方面，聚氨酯镜片成型时间缩短 25%。在光 学树脂材料表面涂覆高硬度透光性薄膜，增加耐磨损性和抗 划伤性能是目前解决树脂材料质软带来的一系列问题最有 效的解决手段。现今高折射光学产品加硬涂层几乎被国外企 业所垄断，极大地制约了我国相关产品的突破创新，所以开 发自主知识产权的高硬度透明薄膜具有重要的经济效益和 社会效益。在 SiO2 有机-无机薄膜基础上，通过添加高折射 率 ZrO2/ TiO2 溶胶制备出 SiO2/金属溶胶复合有机-无机薄 膜。结果表明，复合有机-无机薄膜未发生团聚与相分离，可 以显著提升薄膜的折射率与硬度，薄膜透光性能良好。进一 步探索了中折射率 Al2O3 对复合有机-无机薄膜的影响。结 果表明，Al2O3 溶胶可以很大程度上提高复合有机-无机薄膜 的耐摩擦性能。实现对复合透明薄膜折射率可控调配。采用 凝胶-溶胶法中的有机-无机同步聚合法以异丙醇钛、硅酸四 丁酯为无机纳米粒子前驱体，通过调节体系的 pH、预水解 等方式控制二者以相等的速率共水解，制备得到均匀键和的 硅钛混合无机溶胶液。在上述体系中加入复合交联剂四异丙 基二（二辛基亚磷酸酰氧基）钛酸酯（UP-401）和γ―（2， 3-环氧丙氧）丙基三甲氧基硅烷（KH-560），及成膜助剂羟 丙基纤维素加水引发共缩聚，制备得到以硅钛溶胶混合体为 骨架的有机-无机复合加硬涂层液。通过涂层微观形貌及粗糙度测试发现，涂层结构致密均匀。通过自主研发，实现了国 产高折射聚氨酯镜片的精细化加工。

Industrialization demonstration line of the 1.67 polyurethane lens was optimized and integrated. The industrial demonstration production line has been basically completed with a production capacity of 1 million pieces. In the aspect of short process optimization, the curing time of polyurethane lens is shortened by 25%. 1.67 polyurethane lens has been carried out. All indexes of the product have met the requirements, and the qualification rate of product is equal to that of imported products. Based on SiO2-based organic-inorganic films, SiO2/metal oxides organic-inorganic composite films were further prepared by adding metal oxide sols with high refractive index (ZrO2/ TiO2). The addition of metal oxides sol in proper proportions would cause no agglomeration and phase separation in the organic-inorganic systems. Moreover, the refractive index and hardness of the films were significantly improved, which promised good light transmission performance for the films.To further improve the wear resistance of the films, Al2O3 with medium refractive index was added in the organic-inorganic composite films. Thus, a series of transparent composite films with controllable refractive index were prepared. The results conveyed that the Bayer ratio of the prepared film could reach a maximum up to 7.86, showing that the addition of Al2O3 sol could contribute greatly to the wear resistance of the organic-inorganic composite film. Additionally, by changing the sols blending mass ratio of the composites, the refractive index of the composite transparent films could be controlled. The organic-inorganic simultaneous polymerization was carried out by using titanium isopropoxide and tetrabutyl silicate as inorganic nanoparticle precursors. Phase separation was avoided by controlling the pH, prehydrolysis means and so on to ensure the same hydrolysis rate of Si-sol and Ti-sol. The single factor experiment and orthogonal experiment design found that the total mass fraction of acid and the ratio of TiO2/SiO2 sol are the most important factors affecting the hardness of the coatings. The surface morphology and roughness of the coating were tested. The results showed that the coating structure was dense and uniform. Through independent research and development, the fine processing of domestic high refraction polyurethane lens is realized.
