Method for regenerating lead-removed ABS plastic from waste lead-acid storage battery

The invention discloses a method for regenerating deleaded ABS plastic from a waste lead-acid storage battery. The method comprises the following steps: using the waste lead-acid storage battery formed by an ABS plastic shell as a raw material, extruding and crushing the disassembled shell into large-particle-size fragments, desliming, crushing into particles, and carrying out ultrasonic-assistedswelling treatment on the plastic fragments, adding into dilute sulfuric acid for reaction treatment, removing lead ions therein, cleaning and drying; mixing the modified regenerated ABS plastic particles with PMMA and ABS high rubber powder in proportion after sequentially carrying out chain extension and modification by HTPB and MDI, adding into a vacuum kneading machine for kneading after mixing, and putting into a double-screw extruder for granulating and molding after kneading, thereby obtaining the modified regenerated ABS plastic particles. The method can solve the problem that the ABSplastic shell in the waste
