Abstract
The invention relates to a flexible bond ndfeb magnet. It is uniformly in proportion mixed by the processed rubber binding agent, ndfeb magnetic powder, and processing agent. The mixture method is adopted banbury mixing, roll mixing, pudding process or screw milling. Then the uniformly mixed rubber material is formed to magnet with certain thickness by rolling and plate pressing. Its each composition weight content is that the ndfeb magnetic powder is from eighty seven percent to ninety seven percent; the modified rubber binding agent is from one percent to eight percent; the processing agent is from zero to five percent. The advantages are high production efficiency, low cost and flexibility and elasticity.
