NOVELTY - Leather tanning composition comprises 20-30 pts. wt. nano-layer graphene oxide dispersion liquid, 0.5-1 pts. wt. oxidizing agent, 60-80 pts. wt. monomer mixed solution and 20-30 pts. wt. initiator. USE - Leather tanning composition. ADVANTAGE - The leather tanning composition is distributed uniformly, and ensures improved chemical bonding effect and nano size effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a leather tanning composition, which involves: (A) mixing nano-layer graphene oxide dispersion liquid and oxidizing agent, and then adding mixed monomer liquid solution slowly to them for 1-2 hours; (B) performing heat preservation reaction of the obtained mixture for 2-3 hours, and then reducing the temperature to 40 degrees C of the obtained mixture; and (C) adding sodium hydroxide solution to the obtained material to adjust 5.5-6.0 pH value to obtain the finished product.
