The invention discloses a novel efficient combined additive for zinc electrodeposition. The novel efficient combined additive for zinc electrodeposition is characterized in that the combined additive comprises 0.05-0.2 g/L of bone glue, 0.01-0.1 g/L of aloe gel, 0.01-0.03 g/L of cetylpyridinium chloride; during usage, bone glue, aloe gel and cetylpyridinium chloride are prepared into a solution; the required additives are molten with hot water and then are fully mixed to the fixed volume. The combined additive provided by the invention is used for the zinc electrodeposition process, has a certain creative and positive significance of solving the detail problems during production, improving the current efficiency and the electrolytic zinc quality, reducing energy consumption of zinc electrodeposition and saving the labor cost and also has the great practical production significance of realizing efficient automatic production of zinc electrodeposition, improving the production of zinc smelting, lowering the production cost, increasing the economic benefits of enterprises and other aspects.
