The invention discloses a self-lubrication alloying hot galvanized steel plate for automobiles and a preparation method of the self-lubrication alloying galvanized steel plate. The self-lubrication alloying galvanized steel plate is prepared from the following chemical components in percentage by mass: 0.0007-0.002% of C, less than or equal to 0.01% of Si, 0.08-0.15% of Mn, less than or equal to 0.015% of P, less than or equal to 0.009% of S, 0.02-0.04% of Als, 0.06-0.09% of Ti, less than or equal to 0.004% of N, and the balance of Fe and inevitable impurities. The preparation method comprises the following steps: pre-treating molten iron, smelting in a converter, refining, performing continuous casting, performing hot continuous rolling, pickling, performing cold continuous rolling, annealing, performing hot galvanizing, alloying, rolling a self-lubrication coating by using a roller, drying, and finishing. By controlling the roller system polishing precision and the surface roughness of a roll coating machine, the roller coating process parameters, the temperature of a drying furnace, the machine set speed and the finishing process parameter, the self-lubrication property is achieved. The preparation method is low in production cost and simple in production process, when a self-lubrication alloyed plate prepared by using the preparation method is compared with an ordinary alloyed plate, the lubrication is remarkably improved, the stamping property is also remarkably improved, and the manufacturing of complex components can be completely met.
