Abstract
PURPOSE: To improve the corrosion resistance of the bottleneck portion impossible to be treated with the chemical synthesis and the electrodeposition of the coating film layers, by dipping the object to be coated in the rust-preventive liquid of excellent permeability, before subjecting the object to the degreasing process and the chemical synthesis of the coating film, at pretreating the object to be coated possessing bottleneck portion hardly permitting the penetration of the coating material, before subjecting the object to the coating process.
CONSTITUTION: The object to be coated possessing the bottleneck portion 3 formed by the spot welding 2 applied to two sheets of panels 1, is dipped in the excellently penetrating rust-preventive liquid consisting of, for example, 3-parts of the nonionic rust-preventive surface active agent, 2-parts of the inorganic rust-preventive antioxidant, and 1-part of the nonionic penetrativeness active agent. Since the rust-preventive liquid 7 penetrates into the bottleneck portion 3, at the following treatment for the water-washing, the degreasing, etc., the water and the degreasing solution can not penetrate into the bottleneck portion 3 because they have smaller permeability than the rust-preventive liquid 7, so that the rust-preventive liquid 7 is left behind as it is in the bottleneck portion 3. Next, the chemically synthesized film 4 of zinc phosphate, etc., and the electrodeposited coating layer 5 are formed to finish the pretreatment for the coating work. The bottleneck portion 3 is coated by the rust-preventive material to be left behind after the rust-preventive liquid is dried up, so that the corrosion resistance of the bottleneck portion 3 does not degrade even if it is not coated by the coating film and layers 4, 5.
