Description

一种多种变色太阳镜加工工艺
技术领域
本发明属于太阳镜加工技术领域，具体地说，涉及一种多种变色太阳镜加工工艺。
背景技术
人们日常佩戴的眼镜，具有矫正视力和形象修饰功能。现在，已经出现了根据外界光线的强弱调整其镜片穿透率的变色眼镜，其在白天阳光的直射的情况下降低光穿透率以保护眼睛，在室内又恢复透明以使人得以清晰看东西的功能。变色眼镜可以保护眼镜不受外界强光的刺激。然而，现有技术中的变色眼镜需设置额外的电池提供电力，导致眼镜变得笨重。另外，还有些技术是通过在镜片内层添加偏光变色的膜片，制造工艺复杂繁琐，大大增加了成本，缺乏一种简单，实用，能够变化多种颜色的变色镜片。
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多种变色太阳镜加工工艺，通过配备含有微量光致变色颜料的树脂单体，并在内部加设温致变色的复合膜层，实现多种变色，避免以往单一变色的简单的太阳镜加工。
为了解决上述技术问题，本发明公开了一种多种变色太阳镜加工工艺，其包括：
步骤a.原料制备：将树脂原料与引发剂、光致变色颜料搅拌混合、除气过滤，形成单体，输入储料罐抽真空备用，其中，树脂原料与光致变色颜料的比例为200:1；
步骤b.复合膜层制作：提供醋酸纤维素浆料，通过流延成型工艺制作第一膜层；提供醋酸纤维素混合紫外线吸收剂的混合浆料，通过流延成型工艺制作第二膜层；提供醋酸纤维素混合温致变色颜料的混合浆料，通过流延成型工艺制作第三膜层；将第三膜层至于中央，两面分别通过光固或热固胶水粘连第一膜层与第二膜层，形成复合膜层，并使用弯膜机热压，弯度加工；
步骤c.模具提供：提供内壁具有卡扣环的胶圈，将复合膜层卡扣于卡扣环，并在上下间隔布置玻璃镜片模具；
步骤d.原料充填：在镜片模具之间注入步骤a制备好的原料，固化成型；
步骤e.脱模清洗、切边、加硬液浸泡并清洗、包装入库。
根据本发明一实施方式，其中上述第一膜层、第二膜层、第三膜层厚度都设置为50μm~100μm。
根据本发明一实施方式，其中上述光致变色颜料选自螺恶嗪化合物或吡喃化合物。
根据本发明一实施方式，其中上述步骤b中紫外线吸收剂与温致变色颜料的含量为10%。
根据本发明一实施方式，其中上述温致变色颜料由变色粉混合聚乙烯蜡制得。
根据本发明一实施方式，其中上述温致变色颜料的感温区间在-15℃~60℃，随温度升高颜色渐深。
与现有技术相比，本发明可以获得包括以下技术效果：
通过配备含有微量光致变色颜料的树脂单体，并在内部加设温致变色的复合膜层，实现多种变色，避免以往单一变色的简单的太阳镜加工。
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。
本发明公开了一种多种变色太阳镜加工工艺，其包括：
步骤a.原料制备：将树脂原料与引发剂、光致变色颜料搅拌混合、除气过滤，形成单体，输入储料罐抽真空备用，其中，树脂原料与光致变色颜料的比例为200:1；在本一实施方式中，树脂原料选自CR-39的超韧单体，混合微量的光致变色颜料，光致变色颜料选自螺恶嗪化合物或吡喃化合物，使得固化后的树脂镜片在室外，太阳光下产生渐变的色彩，并且随着光强加大，颜色渐深，提高眼睛的保护性能。
步骤b.复合膜层制作：提供醋酸纤维素浆料，通过流延成型工艺制作第一膜层；提供醋酸纤维素混合紫外线吸收剂的混合浆料，通过流延成型工艺制作第二膜层；提供醋酸纤维素混合温致变色颜料的混合浆料，通过流延成型工艺制作第三膜层；将第三膜层至于中央，两面分别通过光固或热固胶水粘连第一膜层与第二膜层，形成复合膜层，并使用弯膜机热压，弯度加工；在本实施方式中，选用不抗紫外线的第一膜层与抗紫外线的第二膜层夹合温致变色的第三膜层，不仅能够保护内层的起变色效果的第三膜层，而且在温致变色之后可以继续阻抗紫外线对眼睛的灼伤，更能发挥两者效果，变色减弱光强的同时过滤有害波长的紫外光。其中，第一膜层、第二膜层、第三膜层厚度都设置为50μm~100μm，采用微米级膜层，有效吸收光强。同时流延制备膜层，稳定性更好，膜层不容易产生气泡。
步骤c.模具提供：提供内壁具有卡扣环的胶圈，即橡胶制成的偏光眼镜胶圈，将复合膜层卡扣于卡扣环，并在上下间隔布置玻璃镜片模具；
步骤d.原料充填：在镜片模具之间注入步骤a制备好的原料，固化成型；最终在复合膜层前后成型出树脂镜片，同时具备光致变色及温致变色的两种功能，变色效果更好，而且两者叠加，炫彩性加强，色彩混合之后，能够产生多种变色效果，较之以往的单一的偏光镜片或者渐变色的镜片，功能更强。
步骤e.脱模清洗、切边、加硬液浸泡并清洗、包装入库。常规操作，实用方便。
本发明步骤b中紫外线吸收剂与温致变色颜料的含量为10%，多次试验，膜层均匀，紫外线吸收效果较好，变色效果较佳。
温致变色颜料由变色粉混合聚乙烯蜡制得，本实施方式，添加聚乙烯蜡能够使得颜料更为均匀，混合效果更好。
温致变色颜料的感温区间在-15℃~60℃，随温度升高颜色渐深，增强炫彩性，多种变色。
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。
