技术领域
本发明涉及镀膜材制备技术领域，具体为一种智能玻璃阳极电致变色层镀膜材料及其制备方法。
背景技术
电致变色是指材料的光学属性(反射率、透过率、吸收率等)在外加电场的作用下发生稳定、可逆的颜色变化的现象，在外观上表现为颜色和透明度的可逆变化，具有电致变色性能的材料称为电致变色材料，电致变色智能玻璃是电致变色材料的一种，由于其能解决现代不断恶化的城市光污染问题，是节能建筑材料的一个发展方向。
现有的电致变色智能玻璃阳极电致变色层的镀膜材料主要采用镍，为了保证工业化生产，镀膜材料厚度一般较薄，这就导致镀膜材料消耗过快，增加了镀膜材料更换频率，降低了生产效率，同时由于镍金属导磁，镀膜材料又不能过厚，过厚则会影响阴极磁场，从而影响阴极离子流动，变色速度慢，成膜速度慢。
发明内容
针对现有技术的不足，本发明提供了一种智能玻璃阳极电致变色层镀膜材料及其制备方法，具备便于生产，成膜速度快的优点。
本发明为实现技术目的采用如下技术方案：一种智能玻璃阳极电致变色层镀膜材料，配方重量配比为：镍粉40份；铬粉5-10份；氧化锂5-10份；氧化锆球65-70份；纯水29份；分散剂1.8份；氧化钛0.1-10份；氧化锌0.1-5份；氧化铝0.1-5份。
一种智能玻璃阳极电致变色层镀膜材料的制备方法包括以下步骤：
S1、将镍粉、铬粉以及氧化锂加入混合设备中充分混合20h；
S2、然后用热压方式制成镀膜材料，热压温度为780℃，热压压力为22MPa，保压时间为38min；
S3、然后将制成的镀膜材料加入研磨设备研磨成粉；
S4、再添加氧化钛、氧化锌、氧化铝、氧化锆球、纯水及分散剂，研磨混合充分；
S5、经过24小时的干燥后，脱膜形成氧化物的低密度胚体；
S6、将形成的浆料灌入三寸的多孔模具中；
S7、然后在真空烧结炉中经过1150-1430℃的4-5小时烧结，真空度390-3900mmHg，形成溅镀用高密度靶材胚体，经切割与表面研磨成三寸靶材；
S8、接着把所需镀着玻璃基材放入溅镀胚体中，以真空抽气***将溅镀胚体背景压力抽至0.65×10-5-0.85×10-5torr后，通入氩气和氧气的混合气体，混合气体中氧气的体积比为3-5％；
S9、透过节流阀将通入混合气体控制溅镀胚体的工作压力设为2-5×10-3torr，以电源功率147-252W进行溅镀制程，制得150-300nm的透明氧化物薄膜。
作为优化，所述镍粉与铬粉的粒径均为39μm。
作为优化，所述氧化锂的粒径为402μm。
本发明具备以下有益效果：
1、该智能玻璃阳极电致变色层镀膜材料及其制备方法，通过镍粉与铬粉和氧化锂的混合使用，使镀膜材料的质地***，同时降低镀膜材料的导磁性，且不影响镀膜材料的透光性，提高了成膜效率。
2、该智能玻璃阳极电致变色层镀膜材料及其制备方法，通过镀膜材料与氧化钛、氧化锌、氧化铝的混合使用，使镀膜材料的密度更大，更加均匀，从而延长镀膜材料的使用寿命。
