Description
Technical field
The invention belongs to leather chemicals preparation field, be specifically related to a kind of preparation method of the polymer fatliquoring agent containing sulfosuccinates salt structure.
Background technology
Fatting agent is the leather chemicals that in leather processing procedure, usage quantity is maximum.Traditional fatting agent is the composition of micromolecular oil modification product, tensio-active agent and neutral wet goods, and its function is lubrication leather fiber, makes leather soft.Polymer fatliquoring agent is a kind of New-type leather chemical of novel structure, have the long chain alkane that can lubricate leather fiber and the low-molecular-weight polymkeric substance containing hydrophilic radicals such as carboxyls in molecular structure, this structure possesses again retanning and fills function while making it have stuffing effect simultaneously.Polymer fatliquoring agent not only can make retanning and stuffing function integrate, and reduces operation sequence, also has the features such as bonding force is not easily moved by force, in the leather, stuffing effect is lasting, finished leather is soft and full in addition; After metal-salt is closed, finished leather water-repellancy can be improved; Reduce retanning agent and the total consumption of fatting agent to a certain extent, alleviate leather load and the invalid filling of material in leather fiber, make leather hand feeling slim and graceful, sanitation performance is kept to greatest extent; Specific absorption is high, effectively can reduce BOD and the COD value of leather-making waste water.In a word, because polymer fatliquoring agent has higher technology content and industrial application value, the preparation and property research of polymer fatliquoring agent is in recent years paid attention to widely.
