Description
技术领域
本发明涉及高性能塑胶磁性材料及其制备方法。
背景技术
传统橡胶磁和塑胶磁如冰箱贴，磁公仔，磁性明信片，磁性车贴，磁性耗材，都是利用磁性材料磁吸力原理。将铁性面材/制品吸附在磁性底材表面，或将磁性面材/制品吸附在铁板或铁性漆表面，实现无需胶水可随意、反复张贴。很好的避免了一次性使用造成资源浪费，及胶水残留等问题。磁吸附力一方面与磁粉含量有关，粉含量越高，吸附力越大。磁粉含量越高，越容易掉粉，擦黑。虽然对其表面进行哑UV硬化处理，缓解或解决擦黑或掉粉问题，但由于UV硬度高，摩擦系数小，大幅度降低了摩擦力，需增加磁性材料厚度或性能，造成资源浪费。同时，UV油成本不低，气味大，UV单体及溶剂腐蚀性强，接触时容易出现皮肤过敏，对操作有较高的要求。另外，UV厚度影响产品性能，偏厚导致吸力下降，产品变脆，易折断。偏薄易出现固化不彻底，消光粉析出等不足。长时间放置易出现粘黑甚至粘坏被吸附物表面，如冰箱门，车，严重影响产品安全使用和可靠性。
磁吸附力另一方面与磁粉性能有关。磁粉性能越强，成本越高，原材料越难获得，如稀土永磁材料---钐钴(SmCo)永磁材料和钕铁硼(NdFeB)永磁材料。稀土永磁材料成本为普通锶铁氧体永磁的30-80倍。另外，由于钕铁硼极其容易氧化，其表面需进行处理，很难生产加工成薄(0.5mm以下)和宽(1000mm以上)的产品。其超高性能只能用于注塑永磁或烧结永磁，很难用于普通传统压延橡胶磁和塑胶磁。
为了提高吸附力与产品可靠性，不少技术工作者采用普通压敏胶与传统橡胶磁和塑胶磁进行结合。普通压敏胶存在耐候性较差和残胶问题，给使用者带来很大的不便。其残胶主要是因为压敏胶所使用树脂分子链短，分子量小，内聚力低。另外，普通压敏胶涂布在离型膜或离型纸表面，再与磁性材料表面贴合，故其层间粘着力低，长时间与被贴物接触，由于分子链蠕动，很容易出现残胶问题，污染，破坏被贴物表面。
