Description

超薄柔性磁片及用途
【技术领域】
本发明涉及磁性复合体，特别是涉及一种集超薄、超轻、柔性、高磁场利用率等于一体，特别适用于磁性假睫毛的超薄柔性磁片。
【背景技术】
目前，磁性材料已广泛应用于工业、科技等各个领域中，小到磁性钮扣，大到磁悬浮列车，都离不开磁性材料及其应用。工业生产中所用的磁体大多为环状或块状，它们可满足许多的应用需求。但在某些特殊领域，则将磁性的轻薄作为首要条件。例如眼妆品领域，传统的眼妆用假睫毛均通过粘接的方式进行佩戴，其缺陷不言而喻。为此，人们试图通过磁性假睫毛替代传统的粘接式睫毛，这就要求作为假睫毛载体的磁条必须兼具磁性，柔性，轻薄等特性。然而，由于加工条件等限制，现有磁条最薄只能达到0.1毫米，无法使磁条的厚度更薄，重量更轻。因此，开发一种兼具磁性，柔性，轻薄等特性的适合假睫毛用的磁体就成为一种客观需求。
【发明内容】
本发明旨在解决上述问题，而提供一种集薄、轻、柔性、无磁力线外泄等于一体，特别适合用作眼妆用假睫毛载体的超薄柔性磁片。
为实现上述目的，本发明提供一种超薄柔性磁片，该超薄柔性磁片含有按重量百分比计的下列组分：
合成纤维粉末、工程塑料粉末或硅胶粉末2～40
磁体粉末59～97
助剂1～10
将所述各组分按比例混合均匀后，经密炼、挤出、切碎形成混合物料，混合物料通过注塑机注塑成磁性复合体，注塑的同时在强磁场条件下沿所述磁性复合体的横向进行磁场取向，形成各向异性的磁性复合体，然后将磁性复合体沿竖向切割成厚度为0.02～0.4毫米的各向异性超薄柔性磁片。
所述合成纤维为聚酰胺纤维，所述工程塑料为聚苯硫醚。
所述磁体粉末为各向异性釤铁氮磁粉、各向异性的钕铁氮磁粉、各向异性钕铁硼磁粉、各向异性铁氧体磁粉中的一种或几种的组合。
所述注塑取向的磁场强度为0.7T～2.5T。
所述磁性复合体的切割为激光切割或线切割。
所述助剂为硅烷偶联剂。
本发明还提供了该超薄柔性磁片的用途，该超薄柔性磁片用作假睫毛的载体，其与假睫毛结合形成磁性假睫毛。
本发明的贡献在于，其有效解决了磁体的轻薄，特别是用于眼妆的磁体的轻薄问题。本发明通过合理设计磁片所用材料及配比，并通过注塑和挤压工艺形成磁性复合体，再通过先进的切割工艺将磁性复合体切割成厚度仅为0.02～0.4毫米的超薄磁片，真正实现了假睫毛磁体的超薄和超轻，该磁片用于眼妆用假睫毛，可极大提高假睫毛的轻薄性，吸附性，柔韧性和佩戴的舒适性，极大地满足市场对磁性假睫毛的需求。此外，同样重要的是，该磁片可在内部形成磁回路，因此具有高磁场利用率，可避免磁力线对佩戴者眼部的伤害，有效保护佩戴者健康。
【具体实施方式】
下列实施例是对本发明的进一步解释和说明，对本发明不构成任何限制。
本发明的超薄柔性磁片是将合成纤维粉末、工程塑料粉末或硅胶粉末和磁体粉末通过混合，挤出，注塑形成磁性复合体，再通过激光等切割工艺切割成超薄柔性磁片。所述合成纤维为聚酰胺纤维，所述工程塑料为聚苯硫醚，所述磁体粉末为各向异性釤铁氮磁粉、各向异性的钕铁氮磁粉、各向异性钕铁硼磁粉、各向异性铁氧体磁粉中的一种或几种的组合。所述助剂为硅烷偶联剂。所述磁性复合体中，所述合成纤维粉末、工程塑料粉末、硅胶粉末中的一种的重量百分比含量为2～40，磁体粉末的重量百分比含量为59～97，助剂的重量百分比含量为1～10。所述磁性复合体的成型工艺分别为注塑和挤出。
在本发明的实施例中，将重量百分比含量为20的聚酰胺纤维(俗称尼龙)粉末与重量百分比含量为75的各向异性的钕铁氮磁粉粉末和重量百分比含量为5的硅烷偶联剂按所述比例混合均匀后，经密炼炉密炼后挤出并切碎形成颗粒状混合物料，混合物料通过注塑机注塑成磁性复合体，注塑的同时在强度为1.5T的强磁场条件下进行磁场取向，磁场取向的方向是沿所述磁性复合体的横向进行取向，形成各向异性的磁性复合体。然后将磁性复合体通过激光切割机沿磁性复合体的竖向切割成各向异性的超薄柔性磁片，该超薄柔性磁片的厚度为0.02～0.4毫米，具体厚度按实际需求进行选择，最好为0.2毫米。所形成的超薄柔性磁片可按假睫毛的长度和宽度要求切割成用于承载假睫毛的具有磁性和柔性的磁条。
本发明还提供了本发明的超薄柔性磁片的用途，该超薄柔性磁片用作假睫毛载体，将假睫毛通过焊接，粘接，热压等方式连接到该超薄柔性磁片上，形成磁性假睫毛，使用时，两片极性相反的假睫毛可磁力吸附到人的睫毛的两侧，形成睫毛眼妆。
尽管通过以上实施例对本发明进行了揭示，但本发明的保护范围并不局限于此，在不偏离本发明构思的条件下，对以上各构件所做的变形、替换等均将落入本发明的权利要求范围内。
