Description

A kind of composite synthetic fat liquor and preparation method thereof
Technical field
The present invention relates to a kind of fatting agent and preparation method thereof, it is more particularly related to a kind of compound synthesis Fatting agent and preparation method thereof.
Background technology
Fatting agent is the important chemical materials in the skin material and leather processing procedure of dosage maximum in tanning production One of.It can lubricate leather fiber, prevent leather it is stiff, cracking, and can make leather have corresponding toughness and flexibility, And keep its intensity, it may be said that one of an important factor for fatting agent is influence leather quality performance.In curriery, synthetic fat liquor The attention and favor of people is obtained with its excellent stuffing effect, type and quantity are also increasing year by year, belong to height always The fatting agent of shelves.Containing carboxyl, sulfonic group isoreactivity group in higher alcohols sulfosuccinic acid ester molecular structure, have stronger resistance to Sour, alkaline-resisting, salt tolerant ability, moreover it is possible to the good hydrophobicity of leather and fillibility are assigned, so as to stuffing and filling effect, add Fat effect is permanent, and leather is made to keep soft, plentiful, flexible for a long time, and has certain mercerising sense, wax sense and moist feel, reduces The position of hide is poor, improves the water resistance of leather.Therefore, higher alcohols sulfosuccinate is a kind of ideal stuffing material Material has positive meaning to improving resultant leather quality.But at present, synthetic fat liquor type is seldom, and performance is single, majority be all with Low middle-grade fatting agent based on natural oil and its modifier.
Invention content
The object of the present invention is to provide a kind of composite synthetic fat liquor, to solve in the prior art above-mentioned ask Topic, composite synthetic fat liquor fatliquoring function of the invention is good, with the present invention composite synthetic fat liquor can reduce cost, Improve the performance of leather.
Another object of the present invention is to provide a kind of preparation method of composite synthetic fat liquor, and this method is simple, Not high to equipment requirement, the production cycle is shorter.
