NOVELTY - An aqueous surface treating agent comprises 90-110 pts. wt. aqueous polyurethane, 0.01-0.06 pts. wt. graphene, 2-8 pts. wt. aqueous cross-linking agent, 0.2-1 pts. wt. aqueous leveling agent, 0.2-1 pts. wt. aqueous antifoaming agent, 0.3-3 pts. wt. aqueous conditioning agent and 0.5-5 pts. wt. thickening agent. USE - Aqueous surface treating agent for automobile leather. ADVANTAGE - The aqueous surface treating agent has high tensile strength and intensity and better toughness, in ecological and environment-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing an aqueous surface treating agent for an automobile leather, which involves taking aqueous polyurethane, graphene, aqueous cross-linking agent, aqueous leveling agent, aqueous antifoaming agent, aqueous conditioning agent and thickening agent, stirring at room temperature for 10-15 minutes at 800-1000 rpm and uniformly mixing to obtain the finished product.
