The invention provides a high-toughness leather material for an automobile and a preparation method of the high-toughness leather material. The preparation method comprises the following steps of unhairing, alkaline leaching, dealkalization and softening, acid leaching, tanning, fat liquoring and post-treatment. In the step of tanning, starch modified acrylamide and an aluminum complex are adopted for tanning; in the post-treatment step, a coating agent is sprayed on the surface of the leather, and the coating agent comprises the following components in parts by weight: 50-55 parts of N, N-dimethylformamide, 8-13 parts of polyurethane, 8-10 parts of polyamide resin, 8-10 parts of epoxy resin, 3-5 parts of acrylic resin, 5-7 parts of casein, 2-3 parts of hexadecyl trimethyl ammonium chloride, 1-2 parts of hydroxyl silicone oil and 1-2 parts of an auxiliary agent. The prepared genuine leather is good in toughness, resistant to aging and not prone to cracking.
