Description

无线充电器用铁氧体磁片配方及其制备新方法
技术领域
本发明涉及一种铁氧体磁片配方及其制备方法，特别是涉及一种无线充电器用铁氧体磁片配方及其制备新方法。
背景技术
铁氧体是一种具有亚铁磁性的金属氧化物，就电特性来说，铁氧体的电阻率比单质金属或合金磁性材料大得多，而且还有较高的介电性能。铁氧体的磁性能还表现在高频时具有较高的磁导率，因而，铁氧体已成为高频弱电领域用途广泛的非金属磁性材料，由于铁氧体单位体积中储存的磁能较低，饱合磁感应强度也较低，因而限制了它在要求较高磁能密度的低频强电和大功率领域的应用，目前的铁氧体制备成本高，效率低并且合格率差。
发明内容
本发明所要解决的技术问题是提供一种无线充电器用铁氧体磁片配方及其制备新方法，其能够替代传统的铁氧体磁块切割的方法，该磁片不易碎可以弯曲，而且可以做到0.5毫米以下，节省了安装空间，极大地提高了效率及产品合格率，降低了成本。
根据本发明的一个方面，提供一种无线充电器用铁氧体磁片配方，其包括以下重量份数配比的成分原料制得：氧化铁：50-52份、氧化锰：20-22份 、氧化锌：10-12份、二氧化钛：0.1-0.3份、碳酸钙：0.1-0.3份、二氧化硅：0.4-0.6份、三氧化二钴：0.05-0.15份、三氧化二铋：1-3份、三氧化钼：3-5份、五氧化二铌：0.3-0.5份、五氧化二钽：0.4-0.6份、氧化铜：0.1-0.3份、氧化镍：1-3份、碳酸锂：1.5-2.5份、碳酸钠：15-17份、去离子水：100-200份、胶：50-60份。
本发明还提供一种无线充电器用铁氧体磁片制备新方法，其包括如下步骤：
步骤一，首先将氧化铁、氧化锰、氧化锌、二氧化钛、碳酸钙、二氧化硅、三氧化二钴、三氧化二铋、三氧化钼、五氧化二铌、五氧化二钽、氧化铜、氧化镍、碳酸锂、碳酸钠分别碾碎成粉末，再把粉末全部混合在一起；
步骤二，将步骤一混合好的粉末压制成一定形状的毛坯，放入气氛保护窑，在1320摄氏度和气氛下进行烧结，使之生成铁氧体的密度在4.7-5.1克每立方厘米，晶粒尺寸在5-50微米；
步骤三，把生成的铁氧体先进行粗粉碎，粉碎后的粉末再进行细粉碎，使粉碎后的颗粒粒度在1-30微米；
步骤四，将步骤三中粉碎后的粉末与去离子水及胶混合制成料浆，然后进行喷雾造粒，接着把制成的粉料根据用途压制成不同尺寸及形状的磁片材料；
步骤五，把步骤四压制出来的磁片材料放入窑中在100-500摄氏度下进行烧结固化形成磁片；
步骤六，将固化后的磁片进行产品质检，去除瑕疵品，把良品进行包装并存储在仓库。
与现有技术相比，本发明具有如下的有益效果：本发明能够替代传统的铁氧体磁块切割的方法，该磁片不易碎可以弯曲，而且可以做到0.5毫米以下，节省了安装空间，极大地提高了效率及产品合格率，降低了成本。

步骤二，将步骤一混合好的粉末压制成一定形状的毛坯，放入气氛保护窑，在1320摄氏度和气氛下进行烧结，使之生成铁氧体的密度在4.7-5.1克每立方厘米，晶粒尺寸在5-50微米；
步骤三，把生成的铁氧体先进行粗粉碎，粉碎后的粉末再进行细粉碎，使粉碎后的颗粒粒度在1-30微米；
步骤四，将步骤三中粉碎后的粉末与去离子水及胶混合制成料浆，然后进行喷雾造粒，接着把制成的粉料根据用途压制成不同尺寸及形状的磁片材料；
步骤五，把步骤四压制出来的磁片材料放入窑中在100-500摄氏度下进行烧结固化形成磁片；
步骤六，将固化后的磁片进行产品质检，去除瑕疵品，把良品进行包装并存储在仓库。
与现有技术相比，本发明具有如下的有益效果：能够替代传统的铁氧体磁块切割的方法，该磁片不易碎可以弯曲，而且可以做到0.5毫米以下，节省了安装空间，极大地提高了效率及产品合格率，降低了成本。
