| titleOfInvention | A kind of corrosion-resistant neutral chromium-free coating agent and preparation method thereof |
| abstract | The invention relates to metal surface treatment technology, in particular, the invention relates to a corrosion-resistant neutral chromium-free coating agent and a preparation method, belonging to the technical field of chemicals. It includes the following components in parts by weight: 2-10 parts of water-soluble resin, 2-10 parts of small molecule solvent, 10-30 parts of nano-oxide sol, 0-5 parts of film-forming assistant, 1-10 parts of silane coupling agent parts, pH adjuster 0-5 parts, water 50-70 parts. The neutral chromium-free coating agent of the invention is convenient for application, and can be directly contacted with aluminum, magnesium and their alloy plates at normal temperature to produce magnesium-aluminum alloy plates with high corrosion resistance, acid resistance, alkali resistance and hardness requirements. The surface of the aluminum and magnesium alloys using the neutral chromium-free coating agent of the present invention has no discoloration, and a natural color passivation film can be obtained. |
