Composite tourmaline powder capable of efficiently releasing negative ions and preparation method of composite tourmaline powder
The invention discloses composite tourmaline powder capable of efficiently releasing negative ions and a preparation method of the composite tourmaline powder. The preparation method comprises the following steps: mixing rare earth oxide with tourmaline powder, carrying out heat treatment at 500-900 DEG C for 60-70 minutes, carrying out heat preservation at 300-600 DEG C for 2-6 hours, annealing, and carrying out ultrafine grinding for 2-6 hours by a ball milling method to obtain the composite tourmaline powder capable of efficiently releasing negative ions. After the tourmaline powder is subjected to rare earth oxide doping treatment, the negative ion release amount can be remarkably increased, the tourmaline powder can be applied to coating materials, polymer fibers, ceramic materials and the like, and the concentration of negative ions in air can reach 1000/cm < 3 > or above under the condition that the addition amount is 2-5%.
本发明公开了一种高效释放负离子的复合电气石粉体及其制备方法。将稀土氧化物与电气石粉混合，500~900℃热处理60~70分钟，300~600℃下保温2~6小时退火，再经球磨法超细研磨2~6小时，得到所述的高效释放负离子的复合电气石粉体。本发明电气石粉经稀土氧化物掺杂处理后能够显著提升负离子释放量，可应用于涂层材料、高分子纤维、陶瓷材料等，在2~5%的添加量条件下可以使空气中负离子浓度达到1000个/cm3以上。
