The invention relates to a preparation method for a leather tanning agent, in particular to a preparation method for a leather tanning agent with function of strengthening and toughening collagenous fibers. The leather tanning process is a qualitative change process converting raw hide into leather, and can endow the leather with good heat and humidity resistant stability, flexibility and physical and mechanical properties; however, a chrome tanning agent commonly adopted has serious harm to the environment, while a conventional non-chrome tanning agent is hard to meet the requirement on goodservice performance of the leather. The preparation method takes montmorillonite and acrylic monomers as raw materials, and adopts a monomer in-situ intercalation polymerization method to synthesize the toughening type leather tanning agent; and the toughening type leather tanning agent is used for tanning the leather, can greatly improve the strength and toughness of crust leather, and can reduce the dosage of the chrome tanning agent by 75 percent.
