For radio and instrument and meter industry, it is bonded magnetism component, and bonding transformer core etc., it is also possible to this adhesive
Improve the magnetic behavior of component.Magnetic element is made of magnetic material.Adhesive is in magnetic material mainly as magnetic
Dielectric material in medium, effect have two o'clock, bonding and insulation.Bonding is by powdered ferrite bonding forming；Insulation be by
Ferrous powder granules are mutually isolated, and under action of alternating magnetic field, especially under high frequency magnetic field effect, reduce the vortex damage of magnetic medium
Consumption improves quality factor.Powdered ferrite usually is added as adhesive, such as polystyrene, poly- second using certain high molecular materials
Alkene, polypropylene and alcohol-soluble phenolic resin etc., are mainly used for the adhering and sealing of magnetic original part.Such as transformer, the iron core, small of coil
Type magnetic antenna and digital-magnetic tape machine magnetic head, in addition to requiring Precision Machining, precision assembly, it is necessary to using magnetic adhesive
Bonding, sealing technology, it is desirable that it is secured, wear-resisting, stress is small, impact resistance, resistivity are high, but at present because the dispersion of magnetic magnetic powder is uneven
It is even, cause adhesive adhesive property poor, and at present on magnetic adhesive in the market wear no resistance mostly, do not have mechanics and buffer
Performance, do not have elasticity, often fall off because of weak impact failure, and generally have cushion performance adhesive binding metal
Performance again it is poor.Those skilled in the art, it would be highly desirable to a kind of fire-retardant ageing-resistant adhesive of magnetism of low-cost polyurethane is developed, with full
