▎ 摘  要

(CN213291632-U) NOVELTY - The utility model claims a flexible light magnetic film material easy to operate after magnetizing, wherein it orderly comprises a magnetic layer tightly connected, an isolation layer, a decorative or directly printed writing layer, the magnetic layer is a permanent magnetic material; soft magnetic material is a flexible modified polymer composite material layer of filler; the isolation layer is a flexible modified polymer composite material layer of non-magnetic inorganic powder or non-magnetic organic powder as filler; the density of the isolation layer is lower than the density of the magnetic layer tightly connected; hardness and elastic modulus lower than the magnetic layer and decorative or can be directly printed writing layer; the film material continuous non-magnetic phase thickness and film material total thickness of the ratio exceeds 50 %. The utility model is magnetic film product balance the contradiction between light and magnetic requirement; the membrane material whole density is reduced, weight is reduced, the use effect is better. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing flexible light magnetic film material that is easy to operate after magnetizing comprising mixing magnetic powder, adhesive and auxiliary agent, rolling, casting, extrusion molding, mixing non-magnetic material powder, adhesive and auxiliary agent, rolling, casting, extrusion forming, adhering or pressing and forming isolation layer, integrally forming magnetic layer and isolation layer by co-extrusion and casting, covering and decorating or directly printing writing layer, and cutting and magnetizing. DESCRIPTION OF DRAWING(S) - The drawing shows a structure diagram of flexible light magnetic film material that is easy to operate after magnetizing. 1Magnetic layer 2Isolation layer 3Decorative or directly printed writing layer
