The use of ndfeb magnets has become very popular in recent years, and the corresponding products are also full of linglan in the market and have a variety of designs, but the same is true of their black or gray-black appearance, because ndfeb magnets are used due to the limitations of their own limited process characteristics. Most of the magnetic powder is black, the neodymium iron boron powder is gray black powder in appearance, the color is single, and small black or gray black magnetic dots easily cause a dense phobia to people, so that the application and popularization of directly adding the neodymium iron boron powder into cosmetics are restricted.
How to add the neodymium-iron-boron powder into the mask or the eye mask base material after being processed by the microcapsule technology, so that the original color of the neodymium-iron-boron powder is changed in appearance, and technical parameters such as magnetic force, magnetic moment, coercive force, intrinsic coercive force, maximum magnetic energy product and the like of the prepared mask/eye mask base material meet the set requirements of skin, and the prepared mask/eye mask base material is more stable, can resist high temperature and has stronger stability, and no relevant research report exists.
