Description

一种聚氨酯变色镜片及其制备方法
技术领域
本发明属于树脂镜片技术领域,具体涉及一种聚氨酯变色镜片及其制备方法。
背景技术
变色镜片是指在紫外光线照射下颜色会变深的光学镜片,也称为光致变色镜片。根据相关调查显示,目前有超过90%与紫外线辐射相关的皮肤癌是发生在颈部以上的区域,过度暴露于紫外线中眼皮和眼睛周围皮肤有可能导致癌症。除了皮肤癌之外,紫外线辐射还会提高白内障、黄斑变性等多种眼部问题的危险,并会导致免疫系统的破坏。因此,合成变色材料制成变色镜片并且大量推广具有现实意义。
随着社会的发展,各方面对光学塑料的要求存在一定的差异,所以传统的光学塑料在应用方面受到了越来越多的限制。尤其是在制备光学眼镜方面,光学眼镜要求光学塑料有较大的折射率以及较低的色散。相同的折射能力,材料的折光指数越大,则镜片越薄、重量更轻,所以高折光指数光学树脂是目前研究的最主要方向,与此同时,聚氨酯光学树脂的研究大范围开展。
发明内容
本发明的目的是提供一种聚氨酯变色镜片及其制备方法,所制得的镜片性能优异,可广泛应用。

进一步地,所述引发剂为偶氮二异庚腈。
进一步地,所述光致变色材料为螺吡喃类、螺噁嗪类、偶氮苯类、二芳基乙烯类中的一种或几种。
进一步地,所述UV吸收剂为二苯甲酮类、苯并三唑类或吲哚类中的一种或几种。
上述聚氨酯变色镜片的制备方法,包括以下步骤:
步骤1,将丙三醇、3-巯基丙酸、甲苯、对甲苯磺酸混合,在110-120℃回流反应1-2h,经减压蒸馏得到固化剂;
步骤2,将聚酯二醇、异佛尔酮二异氰酸酯、2,2-二羟甲基丙酸加至甲基丙烯酸甲酯和苯乙烯的混合溶液中,混合均匀,加热至45-55℃,加入固化剂、光致变色材料和UV吸收剂,搅拌,得到混合浆料;
步骤3,将混合浆料浇注到模具中,把模具放入空气固化炉中进行一次固化;一次固化结束后,开模、倒边、清洗,然后放入空气固化炉中进行二次固化,即得。
进一步地,一次固化和二次固化的温度为60-100℃。
本发明制得的镜片可见光透视比≥93%,蓝紫光透视比分别为波段280nm-380nm≤0.5%,380nm-420nm≤20%,力学性能优异,可广泛应用。
