Zusammenfassung:The invention provides a bond made from a halogen-free sheet soft magnetic material, a preparation method thereof and a halogen-free soft magnetic sheet. The bond comprises the following components in percentage by weight: 5-30wt% of polyethylene, 70-95wt% of polyolefin copolymers as well as 0.1-2.0wt% of crosslinking agent and 0.1-1.0wt% of antioxygen. The preparation method of the bond comprises the following steps of: 1) adding the components in proportion into a mixer and uniformly mixing; 2) in an intermeshing co-rotating twin screw set, extruding an infused bar by virtue of a melt extrusion reaction grafting technology; 3) cooling with cooling water at a normal temperature, and then slicing and drying to obtain polyolefin elastomer bond particles. The halogen-free soft magnetic sheet provided by the invention is prepared through the following steps: physically mixing 5-12wt% of the polyolefin elastomer bond, 84-92wt% of neodymium iron boron magnetic powder or ferrite magnetic powder, 0.2-3wt% of non-ort
