| titleOfInvention | Stainless steel passivator and preparation method and application thereof |
| abstract | The invention relates to the field of stainless steel passivators, and particularly relates to a stainless steel passivator. A stainless steel passivator, a preparation method and application thereof. The preparation raw materials of the passivator comprise, by weight, 1-3% of a phosphating agent, 0.5-2% of an activating agent, 2-5% of a surfactant, 3-5% of a dispersing agent, 1-2% of a solvent and the balance of water; the activating agent is one or more selected from citric acid, tartaric acid, citric acid, lactic acid, oxalic acid, succinic acid, salicylic acid, ethylenediamine tetraacetic acid and malic acid. The stainless steel passivator provided by the invention can be applied to various medical instruments to form a compact passivation film, so that the heat and humidity resistance stability and the salt mist resistance stability of the medical instruments are improved; the stainless steel passivator provided by the invention is safe and environment-friendly, and does not cause harm to human bodies. |
