High-performance magnetic rubber and its preparation method

A high-property magnetic rubber is prepared from composite permanent-magnet powder (90-97 mass%), rubber (2-9.8), assistant (0.1-0.5) and coupling agent (0.1-0.5) through pulverizing, coating, pugging, calendering and heat treating. Said composite permanent-magnet powder is composed of ferrite-type...

Beschreibung
Zusammenfassung:	A high-property magnetic rubber is prepared from composite permanent-magnet powder (90-97 mass%), rubber (2-9.8), assistant (0.1-0.5) and coupling agent (0.1-0.5) through pulverizing, coating, pugging, calendering and heat treating. Said composite permanent-magnet powder is composed of ferrite-type permanent-magnet, alloy-temp one, and epoxy resin. Its advantages are high magnetic property, better flexibility and high elongate percentage (40-150%).
