摘要： Magnetic or magnetizable composites contain ferrite or rare earth particles in a lightweight flexible binder blend of a semicrystalline polyolefin dispersed within a rubbery matrix. Small but effective amounts of lubricating agents are utilized to improve the processability of the composite which generally lacks any halogen and is environmentally friendly.

摘要： A flexible magnetic blend composition is provided which is comprised of high energy ferrite magnetic particles in a flexible high temperature resistant and oil resistant polymer binder. The binder system is preferably a highly saturated nitrile rubber (HSN) or a polymer alloy of the same in which a HSN is the major polymer containing alloying polymers and/or additives which are compatible with processing, subsequent electron beam curing, and final product performance. The system binder is highly loaded usually from 55 to 65 volume percent with the high energy ferrite particles, i.e, barium and/or strontium ferrite particles, which can produce bonded magnets with a maximum energy product of at least 1.0 megagauss-oersteds, a remenance, Br, of at least 2000 gauss, a coercive force, H c , of at least 1800 oersteds, and an intrinsic coercivity, H ci , of at least 2000 oersteds. The process for production of this system involves the binder system and ferrite particles being mixed, the ferrite particles oriented in a preferred direction during processing, then formed into a final geometry before being cured by high voltage electron beam radiation, preferably in excess of 3,000,000 electron volts. The electron beam curing in the solid state fixes dimensional stability, magnetic properties, oil, solvent, and chemical resistance of the part even when exposed to subsequent hostile temperature environments of 125 o C or higher. Any off geometry parts or trim produced in the process prior to radiation curing can be recycled through processing several times without fear of premature cure.

摘要： An acrylate copolymer is made from an alkyl acrylate and a salt of 2-acrylamido-2-methylpropane sulfonic acid (AMPS). The copolymer is suitable for blending with magnetic particles, e.g. of ferrite material, to make a flexible permanent type magnetic composition. The polymer can be loaded with a large amount of magnetic particles. A carboxylated ethoxyl alkyl phenol surfactant may be used which provides good processability and permits a blend of the magnetic particles with the emulsion acrylate copolymer to be precipitated from a latex solution by high shear mixing. Flexible high magnetic energy magnets can thus be made and utilized in various applications such as refrigerator doors, electrical motors, and the like.
