POLY HYDROXYL ALKYL PHOSPHINE-ORGANIC SILICON TANNING AGENT, ITS PREPARATION AND APPLICATION IN FUR TANNING

摘要

This invention relates to a poly hydroxyl alkyl phosphine-organic silicon tanning agent, its preparation, and its application in fur tanning; the poly hydroxyl alkyl phosphine comprises organic silicon of molecular mass range 10,000-200,000, surface active agent, stabilizer and pure water; in the application of leather and fur tanning, the silicon tanning presents many advantages: it does not alter fur indumentum, the tanned fur has good dry/wet washing toleration, the leather does not de-tan, the tanning agent itself has low toxicity, no potential safety hazard, does not accumulate in the body of organism, and does not cause cancer, deform and genetic mutation.
