Abstract

本发明提供了一种防晒玻璃。该防晒玻璃按重量百分比含有:SiO269.50～73.50%,Al2O34.00～6.00%,B2O37.70～9.70%,Na2O4.50～7.5%,TiO22.50～4.50%,CeO20.20～0.80%,BaO1.10～2.10%。本发明能有效截止紫外线,保护皮肤,对人体有益无害,防晒玻璃表面光洁美观。防晒玻璃粉剂可作为护扶霜添加剂。

Description

防晒玻璃
本发明涉及的是一种防晒玻璃，属于硅酸盐玻璃领域。
已有的防紫外线玻璃的品种繁多，但不适用于人体皮肤，因为①大多数玻璃含有砷或锑等有毒氧化物；②其pH值偏高或偏低，不符合《中华药典》标准，偏离人体所能承受的范围；③防晒技术性能不同，因用于人体防紫外线玻璃微粉有特殊的安全标准。
鉴于以上原因，本发明的目是为了提供一种有效截止紫外线，保护皮肤，对人体有益无害的防晒玻璃。
本发明的目的是这样来实现的：
本发明防晒玻璃按重量百分比含有：
    SiO2    69.50～73.50％
    Al2O3 4.00～6.00％
    B2O3  7.70～9.70％
    Na2O   4.50～7.50％
    TiO2   2.50～4.50％
    CeO2   0.20～0.80％
    BaO     1.10～2.10％
上述的防晒玻璃按重量百分比含有：
    SiO2    69.50～73.50％     Na2O   4.50～7.50％
    Al2O3 4.00～6.00％       TiO2   2.50～4.50％
    B2O3  7.70～9.70％       K2O    0.70～1.30％
    CaO      0.50～1.10％       CeO2   0.20～0.80％
    ZnO      0.50～1.50％       Li2O   0.20～0.60％
    BaO      1.10～2.10％       Fe2O3  余量
上述防晒玻璃中的Fe2O3控制在0.6以下。
本发明防晒玻璃中，SiO2、Al2O3、B2O3、Na2O是玻璃中的主体，形成骨架，B2O3、Na2O调整pH值，B2O3加强网络Na2O助熔；CaO、BaO、ZnO、K2O是结构网的中间层，可调整玻璃的性质，增加光泽、美感；Na2O、K2O是玻璃结构网络最外层，使玻璃易于熔制；TiO2、CeO2参与网络形成，截止紫外线。
本发明有截止紫外线功能，且不含有毒氧化物，其粉剂理化性能优良，对人体皮肤无刺激。根据光吸收测试；紫外线被全部截止(见图1)，pH值在6.5～7.5之间，根据需要，可微调。
本发明防晒玻璃可有效截止紫外线，保护皮肤，对人体有益无害。防晒玻璃表面光洁、美观。本防晒玻璃粉剂可作为护肤霜添加剂。
下面详细说明本发明的实施例(见表1)。
