Description
技术领域
本发明属于镜片技术领域,具体地说,涉及一种旋涂式偏光镜片的制造工艺。
背景技术
传统偏光镜片的制造工艺主要为基材通过贴合、内嵌等方式加入偏光薄膜实现偏光功能,制造工艺较为繁琐且可以结合的基材有限,导致镜片的偏光率受限,另外生产效率得到下降。
因此,目前急需一种新型,简便,高效,性能更广的偏光镜片的制备工艺。
发明内容
有鉴于此,本发明所要解决的技术问题是提供了一种旋涂式偏光镜片的制造工艺,用于避免以往偏光镜片需要在镜片基体内通过贴合、内嵌等方式加入偏光薄膜,使得偏光镜片制备繁琐的麻烦。
为了解决上述技术问题,本发明公开了一种旋涂式偏光镜片的制造工艺,其包括:
步骤a.提供固化脱模后的树脂基片,所述树脂基片具有光学凸面、光学凹面、及光学端面;
步骤b.将上述树脂基片送入清水槽和加硬液槽中分别进行清洗和加硬循环,并取出烘干;
步骤c.将烘干后的树脂基片送入镀膜机内,采用真空离子溅射将非金属氧化物和金属氧化物熔化后溅射收附到树脂基片表面,形成膜层;
步骤d.提供偏光涂层液,所述偏光涂层液包括30%~45%的聚乙烯醇、25%~35%的丙烯酸酯化合物、23%~35%的乙酸丁酸纤维素、4%~10%的光引发剂、6%~15%的热硬化剂;
步骤e.将树脂基片固定至旋涂仪,并将偏光涂层液注入胶枪,对于树脂基片的表面进行旋涂操作,形成偏光膜层;
步骤f.清洗烘干,包装入库。
根据本发明一实施方式,其中上述光学凸面与所述光学凹面弯度不同。
根据本发明一实施方式,其中上述光学凸面的弯度大于所述光学凹面的弯度。
根据本发明一实施方式,其中上述非金属氧化物和金属氧化物包含氧化铟锡、二氧化硅、三氧化二铝、二氧化锆。
根据本发明一实施方式,其中上述偏光膜层厚度为10-100μm。
与现有技术相比,本发明可以获得包括以下技术效果:
通过开发旋涂偏光涂层,结合开发旋涂工艺进行偏光功能实现,实现加工方便、加工品种自由设计,制成镜片偏折率达95%以上。
当然,实施本发明的任一产品必不一定需要同时达到以上所述的所有技术效果。
具体实施方式
以下将配合实施例来详细说明本发明的实施方式,藉此对本发明如何应用技术手段来解决技术问题并达成技术功效的实现过程能充分理解并据以实施。
本发明公开了一种旋涂式偏光镜片的制造工艺,其包括:
步骤a.提供固化脱模后的树脂基片,所述树脂基片具有光学凸面、光学凹面、及光学端面;
步骤b.将上述树脂基片送入清水槽和加硬液槽中分别进行清洗和加硬循环,并取出烘干;
步骤c.将烘干后的树脂基片送入镀膜机内,采用真空离子溅射将非金属氧化物和金属氧化物熔化后溅射收附到树脂基片表面,形成膜层;
步骤d.提供偏光涂层液,所述偏光涂层液包括30%~45%的聚乙烯醇、25%~35%的丙烯酸酯化合物、23%~35%的乙酸丁酸纤维素、4%~10%的光引发剂、6%~15%的热硬化剂;
步骤e.将树脂基片固定至旋涂仪,并将偏光涂层液注入胶枪,对于树脂基片的表面进行旋涂操作,形成偏光膜层;
步骤f.清洗烘干,包装入库。
在本发明一实施方式中,树脂基片通过为树脂单体经过固化炉或者紫外光固化成型的镜片基体,具有光学折射率,其正反两面分别设置光学凸面和光学凹面,实现屈光度的成型。
将树脂基片脱模后,转送入清洗池进行清洗,然后在加硬液中加硬,并多次循环清洗加硬,完成树脂基片表面的硬度增加。之后再送入镀膜机内,根据需要进行基片表面的镀膜处理,形成符合各种需求的膜层。
优选一实施方式中,真空溅射的非金属氧化物和金属氧化物包含氧化铟锡、二氧化硅、三氧化二铝、二氧化锆。实现树脂基片表面的减反射,提高透光率,并且有效滤除有害波段的蓝光,减小辐射,提高眼睛的防控。
偏光涂层液由30%~45%的聚乙烯醇、25%~35%的丙烯酸酯化合物、23%~35%的乙酸丁酸纤维素、4%~10%的光引发剂、6%~15%的热硬化剂组成,借以提高树脂基片的偏光效果,较之以往采用在镜片基体内通过贴合、内嵌等方式加入偏光薄膜,本发明通过制备偏光涂层液,在旋涂仪的帮助下,开发旋涂工艺进行偏光功能实现,实现加工方便、加工品种自由设计,减小了制备繁琐的麻烦,提高了生产效率,适用性广。而且其中添加乙酸丁酸纤维素,形成的偏光膜层持久性高。本发明的偏光膜层厚度为10-100μm,偏光效果好。
在一实施方式中,本发明的光学凸面与光学凹面弯度不同,借此完成高屈光度成型的同时,减小树脂基片周围的壁厚,减小佩戴重量。优选低,光学凸面的弯度大于所述光学凹面的弯度,实现高屈光度成型。
综上所述,本发明通过开发旋涂偏光涂层,结合开发旋涂工艺进行偏光功能实现,实现加工方便、加工品种自由设计,制成镜片偏折率达95%以上。
上述说明示出并描述了本发明的若干优选实施例,但如前所述,应当理解本发明并非局限于本文所披露的形式,不应看作是对其他实施例的排除,而可用于各种其他组合、修改和环境,并能够在本文所述发明构想范围内,通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围,则都应在本发明所附权利要求的保护范围内。
