Description

一种树脂镜片耐酸碱腐蚀膜
技术领域
本实用新型涉及光学镜片领域,尤其是关于一种新的树脂镜片膜层的设计,以提高树脂镜片耐酸碱腐蚀的能力。
背景技术
随着眼镜技术的发展,树脂镜片的种类越来越多,为了提高树脂镜片的透过率,一般需要镀膜,而镀膜的膜层在遇到酸或碱性环境时容易受到破坏。树脂镜片的硬度较低,所以一般都要进行加硬处理;并且树脂镜片的透过率不高,比如CR39的透过率是92%,所以非镀膜镜片影响了我们对所看见物体的判断。大多都在镜片的反射颜色上下工夫,而没有去提高镜片本身的性能,比如现在的酸雨比例越来越高,在洗涤眼镜镜片时会用到碱性溶液,这就要求镜片的膜层有一定的耐酸碱腐蚀的能力。
发明内容
针对以上不足,本实用新型的目的在于提供一种新的膜层,来抵抗酸或碱的腐蚀,使镜片的寿命得到延长。
本实用新型的技术方案是通过以下方式实现的:一种树脂镜片耐酸碱腐蚀膜,由二氧化硅层、减反射膜层、加硬层和基片组成,其特征在于:所述的在二氧化硅层和减反射膜层、减反射膜层和加硬层之间分别增设有在镍铬合金层。
所述的减反射膜层和加硬层之间的镍铬合金层的厚度为0.6-1nm,减反射膜层和二氧化硅层之间的镍铬合金层的厚度为1.5-2nm。
本实用新型结构,在真空镀减反射膜层前加了一层镍铬合金,可以起到保护加硬层和连接加硬和减反射层的作用;在减反射膜层和防水膜层间也加了一层镍铬合金层,可以起到保护减反射膜层,提高减反射膜层的耐酸碱腐蚀的能力。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
由图1知,本实施例的树脂镜片耐酸碱腐蚀膜,,由二氧化硅层1、减反射膜层3、加硬层5和基片6组成,在二氧化硅层1和减反射膜层3之间设有在镍铬合金层2,在减反射膜层3和加硬层5之间设有在镍铬合金层4。减反射膜层3和加硬层5之间的镍铬合金层4的厚度为0.6-1nm,减反射膜层3和二氧化硅层1之间的镍铬合金层2的厚度为1.5-2nm。
用本实用新型技术方案做出来的普通树脂镜片可在PH值为12-13的强碱性溶液中测试10分钟,而膜层无任何损害。
