Abstract

The invention discloses a composite passivating agent for a copper alloy metal plate, and belongs to the technical field of surface passivating treatment. The composite passivating agent is prepared from the following components in percentage by mass: 5 to 15% of sodium alginate, 0.5 to 3% of N-methyl-isothiazolinone and 5-chloro-N-methyl-isothiazolinone mixture, 0.5 to 3% of calcium propionate, 0.5 to 2% of isooctyl glucoside, 0.05 to 0.5% of high-carbon alcohol fatty acid ester complex, 0.05 to 0.3% of ethylene oxide and high-grade fatty alcohol mixture, 0.1 to 2% of barium stannate nanorod,and the balance of water, wherein the diameter of each barium stannate nanorod is 20 to 100nm, and the length is 500nm to 1mu m. The composite passivating agent has the advantages that the pretreatment before use is not required; after passivated by the composite passivating agent, the copper alloy metal plate has good salt resistance, weather resistance, water resistance, acid resistance, alkaline resistance, solvent resistance, fingerprint resistance and lubricating property.

Description

technical field [0001] The invention belongs to the technical field of surface passivation treatment, and in particular relates to a composite passivator for surface treatment of copper alloy metal plates. Background technique [0002] Copper alloy metal plates are widely used in the fields of electronics and decoration due to their excellent physical and chemical properties, but the chemical properties of copper are relatively active. It is easy to cause corrosion of the copper alloy metal plate and seriously affects the surface quality of the copper alloy metal plate. In order to improve the corrosion resistance, surface decoration and service life of the copper alloy metal plate, passivation treatment is required to form a passivation film with high density and high stability on the surface of the copper alloy metal plate. Passivation treatment is widely used due to its simple equipment and easy operation. The traditional passivation process mainly adopts chromate passi...
