The invention provides a door curtain comprising a door curtain body. The inner side edges of the door curtain body are provided with a plurality of magnetic members; the door curtain body is divided into two parts and every two magnetic members arranged at the corresponding positions of the different parts have different polarities. The door curtain is characterized in that a memory metal strip is arranged between every two magnetic members arranged on the same part; the magnetic members at least include two balance weight magnets arranged at the lower corner points of the inner side of the door curtain body separately; the door curtain also comprises a mating member; when the door curtain body is in an opened state, the mating member provides opposite restoring force for the balance weight magnets; when the door curtain body is fully opened, first reset force is provided via the memory metal; when the door curtain body is nearly closed, the magnetic blocks provide second reset force, so that the door curtain body is fully closed; when the first reset force is reduced, the second reset force is increased, so that the service life is prolonged; during opening, the initial deformation restoring force of the memory metal is small and the magnetic attraction force is large, so that the door curtain is not extremely difficult to open.
