An anisotropic flexible magnetic strip for magnetic health

Abstract

The invention relates to the field of magnetic materials, in particular to an anisotropic flexible magnetic stripe suitable for magnetism health. The anisotropic flexible magnetic stripe is prepared through the following steps in sequence: preparation of gyromagnetic ferrite powder: pre-sintering a gyromagnetic ferrite blank by using microwaves, and smashing to obtain the gyromagnetic ferrite powder; pre-magnetization and microwave pelletizing: uniformly mixing rare earth compound permanent magnetic powder and the gyromagnetic ferrite powder treated by using anti-rust oil together with 4-15 parts of bonding agent, 1-5 parts of heat stabilizer, 0.5-2 parts of coupling agent and 0.2-0.8 part of antioxidant solution, pre-magnetizing, and performing microwave vacuum drying to form agglomerated magnetic particle clusters; performing primary calendering; magnetic field orientation: cutting a primarily-calendered flexible magnet into magnetic stripes, heating, preserving heat, and performing heat tracing magnetic field orientation; secondary calendering: performing secondary calendering on the magnetic field-orientated magnetic stripes at 30-40 DEG C. The prepared magnetic stripe is excellent in performance and higher in ageing resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of magnetic materials, in particular to an anisotropic flexible magnetic strip suitable for magnetic health. Background technique [0002] The function of magnetism on the human body is simply to properly regulate the autonomic nerves so that the blood circulation can meet the needs of the human body, thereby improving various internal organ functions. When the magnetic force is applied to the human body, a voltage (electromagnetic induction) will be generated, and the voltage will cause the blood to generate an electric current, cause electrolyte dissociation, increase ions, and regulate the autonomic nerves. Since the autonomic nerve controls blood circulation, blood pressure, heart rhythm, metabolism, hormone secretion and almost all the functions of internal organs. Just like when the blood circulation is good, the blood can quickly carry the nutrients (electrolytes, vitamins, etc.) and oxygen we inhale through t...

Problems solved by technology

[0003] The magnets for magnetic therapy bedding use rare earth flexible magnetic strips. The earliest plastic magnets are flexible ferrite, which can be made into magnetic plates and magnetic strips, but the surface magnetic induction is low, which is difficult to meet the needs of health-care bedding.

[0004] CN1624824A (2005-6-8) discloses a patent on a flexible bonded NdFeB magnet and its manufacturing method. It introduces that the modified rubber binder and NdFeB magnetic powder and processing aids are first introduced. The agent is mixed evenly in proportion, and then the mixed rubber material is made into a flexible bonded magnet with a certain thickness by calendering or flat pressing, but this method is not conducive to the preparation of flexible anisotropic bonded magnets with excellent magnetic properties.
