Description

一种镜片光学膜
技术领域 本发明涉及一种光学产品， 尤指一种镜片光学膜产品。 背景技术 眼镜镜片是一种典型的光学产品， 而在该领域， 厂商总是希望增 加产品的性能， 比如变色性能、 偏光性能、 防紫外线性能， 以及制作 出更多的颜色等等。对于以上的这些特性都是通过增加相应的膜层来 实现的。 然而， 其 艺制作以及处理上存在一定的难度， 并且成本较 高，而且以上的这些特性在刮伤或是长久配带后都有可能使行性能减 弱甚至消失。
之后， 就有一些早期厂商在塑胶镜片（TAC层）表面使用变色染 料工艺， 譬如： U.S.Pat.No.5，130,353或 U.S.Pat.No.5，185,390等专利， 他们将 TAC层 Γ直接浸入到变色染料或者其他能导致变色的化合物 内， 这样即在塑胶镜片的表面涂上一层变色层 2' (如图 1所示）， 再 通过加热的方式使其渗到镜片当中。然而对于这种将变色层 2'包覆于 TAC层 1'之外的制作工艺， 由于染色粒子的厚度不均， 常会产生染色 不均的问题， 若要保持镜片较长时间的不变色， 需要精确控制染料的 吸收， 并且实际操作起来较为困难， 成本也较高。 此外， 当有要求变 色时间差时， 则无法达到要求， 其变色时间緩慢。
再者， 一般镜片都需要具有一定标准的防紫外线性， 而有的镜片 还需要增加偏光等性能， 此时， 则需要将吸收紫外线材料层或偏光层 等贴合于塑胶层表面， 其同样会出现易脱落的现象。 发明内容 本发明的目的在于提供一种镜片光学膜产品，其可避免出现染色 不均的现象， 且可防止脱色， 还很容易控制变色时间。
为实现上述目的， 本发明的技术解决方案是：
一种镜片光学膜产品， 至少包括塑胶层、 变色层及吸收紫外线材 料层， 所述变色层及吸收紫外线材料层贴合于至少两层塑胶层之间。
所述两层塑胶层之间还贴合有偏光层和 /或染色层。
所述塑胶层为 TAC层、 DAC层或 AC层。
所述变色层为 PET、 PC或 TAC制成。
采用上述方案后，由于本发明系将变色层及以贴合工艺夹合在呈 :两层塑胶层之间， 而不是像现有技术那样， 采用浸染技术， 将变色 层涂覆于塑胶层之外， 因此可避免染色不均的现象， 同时可防止变色 层脱落。 再者， 由于变色层系独立成型后再与塑胶层贴合， 因此可很 好控制变色时间， 不会出现变色时间緩慢的现象。 此外， 本发明同样 将吸收紫外线材料层也贴合于两塑胶层之间， 因此也可防止其脱离。 附图说明 图 1是现有镜片光学膜产品的结构示意图;
图 2是本发明笫一实施例的结构示意图；
图 3是本发明笫二实施例的结构示意图；
图 4是本发明第三实施例的结构示意图。 具体实施方式 本发明所述镜片光学膜产品的第一实施例如图 2所示，其以贴合 工艺， 在两层 TAC ( Tri-acetate Cellulose, 三醋酸纤维素）层 1之间 贴合有一层变色层 2、 及一层吸收紫外线材料层 4， 该变色层 2及吸 收紫外线材料层 4均为预先成型的膜结构。由于本发明不采用浸染技 术， 因此可防止染色不均的现象； 且由于系将变色层 2及吸收紫外线 材料层 4夹合在两层 TAC层 1之间， 从而可防止脱色； 再者， 独立 成型的变色层， 可 ί艮好控制变色时间。
本发明第二实施例如图 3所示， 其同样以贴合工艺， 先将 TAC 层 1与变色层 2贴合在一起， 而为使光学产品具有偏旋光性能， 可再 于两 TAC层 1之间加贴一层偏光层 3,为使光学产品具有防紫外线性 能，可再于两 TAC层 1之间加上吸收紫外线材料层 4,最后再贴合一 层 TAC层 1。 本实施例同样将变色层 2夹合于两 TAC层 1之间， 同 时在 TAC层 1之间还加贴了偏光层 3及吸收紫外线材料层 4， 因此， 其同样可达到避免染色不均、 防止脱色及容易控制变色时间的目的。
本发明第三实施例如图 4所示，本实施例与第二实施例的不同之 处在于：在 TAC层 1之间还贴合有一层染色层 5,从而使光学产品可 呈现出不同的顏色。— .
需要说明的是， 所述 TAC层即为塑胶层， 其并不局限于 TAC— 种材质， 也可为其它材质， 如 DAC ( Diacetate Cellulose, 二醋酸纤维 素）层或 AC层等等。 此外， 所述变色层也可为任何材质， 如 PET、 PC、 TAC等等， 其中以 TAC为最优， 在此需要强调的是， 虽然塑胶 层与变色层都可以 TAC制成， 再两者的加工工艺却不同， 前者为透 明层， 且经过强化处瑝， 不会被磨伤， 而后者的耐磨性较差， 因此置 于外表面易刮伤脱落。
再者， 所述偏光层、 吸收紫外线材料层或染色层等， 均为可实现 某种功能的特性层， 各层及其与变色层之间的组合方式， 及各层的排 放顺序， 均可任意组合排放， 甚至业者可以按照自己的要求增加其他 的一些特性层。 此外， 所述 TAC层（塑胶层）也并不局限于上述两 层， 其也可为三层或更多层， 而且只要保证有两层 TAC层设置于最 外层， 其余 TAC层与上述特性层之间则可任意組合排列。
