Problems solved by technology

Chinese patent CN201110072391.4 discloses a chromium-free composite passivator and its preparation method, including phosphoric acid, acetic acid, sodium molybdate, cerium chloride, γ-methacryloxytrimethoxysilane, epoxy resin, Acrylic resin and ethanol, etc., the passivation solution is close to the corrosion resistance of hexavalent chromium passivation, but because the solvent contains 20-40% ethanol, and ethanol has strong volatility, resulting in insufficient product and passivation production Stablize

Embodiment 1

[0035] An environment-friendly passivation solution for stainless steel products, the content of each component by mass percentage is: 20.0% citric acid, 5.0% phytic acid, 0.5% cerium nitrate, 2.0% sodium molybdate, 2.0% triethanolamine, nano-silica sol Dispersion liquid 1.0%, water-based acrylate 1.0%, γ-(2,3-glycidoxy)propyltrimethoxysilane 1.0%, sodium dodecylsulfonate 2.0%, and the balance is water;

[0036] Its passivation method includes the following steps:

[0037] Pretreatment of stainless steel products: use cleaning agent to clean the surface of stainless steel products by soaking or spraying for 3 minutes; then use 1-2 channels of tap water for immersion cleaning for 5 minutes;

[0038] Passivation solution preparation: Dilute the prepared passivation solution stock solution with deionized water, the dilution ratio is 1:6, and the pH value of the diluted passivation solution is about 2.0;

[0039] Passivation: Use the diluted passivation solution to pickle and pas...

Abstract

The invention discloses an organic and inorganic composite passivation solution and a passivation method. The content of each component in the passivation solution is as follows: citric acid 20.0-35.0%, phytic acid 5.0-15.0%, cerium nitrate 0.5-2.0%, sodium molybdate 2.0-3.0%, triethanolamine 2.0-3.0%, nano silicon Sol dispersion 1.0‑5.0%, water-based acrylate 1.0‑5.0%, γ‑(2,3‑glycidoxy)propyltrimethoxysilane 1.0‑5.0%, sodium dodecylsulfonate 2.0‑10.0 %, the balance is water. The passivation method includes the steps of pretreatment of stainless steel products, surface pickling passivation, cleaning and drying. The composite passivation solution of the invention does not contain nitric acid and chromate, greatly reduces environmental pollution, and can achieve the passivation effect of the traditional "nitric acid + chromate" process.

Description

technical field [0001] The invention relates to the field of passivation solutions, in particular to an organic-inorganic composite passivation solution and a passivation method. Background technique [0002] As the most frequently used bathroom products in the kitchen, stainless steel products are faced with the failure to fully remove the iron impurities on the surface of the stainless steel products before leaving the factory, and the lack of surface protection measures for stainless steel products, resulting in some users having stainless steel products before they actually move in. Rust phenomenon affects product experience. [0003] In order to overcome the above problems, it is necessary to improve the corrosion resistance of stainless steel products. At present, the passivation protection technology of stainless steel products is mainly used in the industry. Most of the traditional passivation technologies for stainless steel products use "nitric acid / concentrated s...
