Abstract

The invention discloses an environment-friendly nickel-plating rust-proof sealing agent and a preparation method thereof and belongs to the technical field of metal surface treatment. The environment-friendly nickel-plating rust-proof sealing agent is characterized in that 100 parts of the sealing agent comprise, by mass, 6.0-10.0 parts of lithium silicate, 0.6-1.5 parts of sodium silicate, 0.6-1.0 part of sodium molybdate, 0.4-0.6 part of sodium phytate, 0.1-0.2 part of benzotriazole, 0.4-0.6 part of polyethylene glycol, 0.4-0.6 part of polyving akohol, 1.0-2.0 parts of triethanolamine, and the balance deionized water. The nickel-plating rust-proof sealing agent is environmentally friendly, safe and good in stability and has remarkable anti-corrosion effect on steel nickel-plating parts, and gelling is not prone to occurring.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an environment-friendly nickel-plating anti-rust sealant and a preparation method thereof. Background technique [0002] For many steel parts, nickel plating is widely used for anti-rust and decorative needs. Nickel coatings on steel parts are cathodic and can only provide complete mechanical protection if the coating is free of porosity. The thickness of nickel plating without porosity is generally more than 24 microns, the price is high, and most parts are difficult to achieve. At present, copper plating is generally used as the base and then thin bright nickel plating process. In order to reduce the cost, the bright nickel coating is only 4-5 microns, and there are inevitably pores. The corrosive medium passes through the pores, corroding the copper base first, and then corroding the iron substrate. The corrosion resistance of the coating is not good, and it...
