| titleOfInvention | Organic metal complex tanning agent and preparation method thereof |
| abstract | The invention discloses an organic metal complex tanning agent and a preparation method thereof. The organic metal complex tanning agent is excellent in stability performance and good in tanning property, not only has a metal tanning characteristic, but also has the tanning properties of an organic tanning agent, meets tanning physical-mechanical properties and endows tanned leather with good sensory characteristics; and meanwhile, the tanning agent is relatively low in cost, chromium-free and formaldehyde-free, can be used for main tanning and retanning processes, is suitable for production of various leathers and furs and provides the technical backstopping for clean leather production. The preparation method for the organic metal complex tanning agent comprises the following steps: enabling chromium-free metal salt and an unsaturated organic monomer with an active functional group to be in coordination reaction in an aqueous medium, preparing an intermediate product into organic metal salt after the intermediate product is subjected to free radical polymerization under a certain condition, and adjusting alkalinity, carrying out masking reaction and refining in the later period. |
