Abstract
本发明公开一种玻璃仿古金属真空镀膜,包括玻璃基板,所述的玻璃基板上设有三层膜,由内向外依次为第一层金属铬膜、第二层非金属硅膜和第三层氧化铬膜。通过真空电镀膜方法,镀上三层膜,把所需的金属或非金属材料镀在玻璃表面,再经加热工序,使其最表层膜氧化成整片均匀而微观局部不均匀的透明光学膜,这些膜叠加起来形成非常逼真的古铁、古铜、古青铜等效果。
Description
技术领域
本发明涉及玻璃表面镀膜技术,尤其是一种玻璃仿古金属真空镀膜及其工艺。
背景技术
目前,建筑装饰用的仿古金属板材或马赛克等产品,大多用金属铝板、铜板或不锈钢板材进行化学转化膜处理,该加工会产生六价铬污染,膜层的耐磨和耐腐蚀性能差,大量耗费金属材料,加工较困难,成本高。
发明内容
本发明的目的是提供一种玻璃仿古金属真空镀膜及其工艺,通过真空电镀膜方法,镀上三层膜,把所需的金属或非金属材料镀在玻璃表面,再经加热工序,使其最表层膜氧化成整片均匀而微观局部不均匀的透明光学膜,这些膜叠加起来形成非常逼真的古铁、古铜、古青铜等效果。
玻璃基板表面的第一层是通过真空镀膜的金属铬,其金属铬的厚度为50-100nm,作用是反射金属质感的底层。
第二层为非金属硅,厚度为50-150nm,该层非金属硅呈光学膜现象,即在金属铬上面镀上非金属硅,随着硅层厚度增加,颜色从银白、黄铜、棕红到灰紫色,作调节颜色用,该层硅膜被加热至580℃以下不变色,可稳定控制产品颜色。
第三层即最表面层为金属铬,厚度为30-100nm,该层膜当被加热至400-550℃时会被氧化,成为呈透明状的氧化铬膜,该膜反射光呈灰黄色,透光呈淡棕色,这层灰黄色的透明膜叠加上去后,可呈现很好的古金属效果。
本发明的有益效果是:通过本工艺制作的玻璃仿古金属膜产品,由于应用加热烧膜工艺,大量节省真空镀氧化膜的时间,降低生产成本,同时利用玻璃的热胀冷缩的表面移动过程以及光学膜的特性,使其仿古金属效果更逼真生动;用玻璃代替金属材料成本低,取代化学转化膜工艺无污染,使产品的耐磨和抗腐蚀性能比不锈钢产品高,适合户外实用,使产品成为高档仿古建材装饰品。
