Foamed micropore layer of artificial leather for lining of PE shoes and method for preparing artificial leather by using same

The invention discloses a foamed micropore layer of artificial leather for lining of PE shoes and a method for preparing artificial leather by using the same. The components of the foamed micropore layer comprise polyethylene, ethylene-vinyl acetate copolymer, styrene-butadiene copolymer, active calcium carbonate, azodicarbonamide, zinc oxide, white pigment, dicumyl peroxide and antioxidant. The preparation method comprises the following steps of: adding the prepared raw materials to a high-speed mixer and mixing the raw materials; conveying the mixed material to a hopper of an extruder and plasticizing the material; conveying the plasticized material to a four-roller calendar and rolling the material into a thin film; laminating the thin film on a fabric foundation in a rolling manner and trimming the thin film; winding the thin film by a winding machine to form the semi-finished product, conveying the semi-finished product to an oven and carrying out the cross-linking foaming on thesemi-finished product; ta
