Description
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 skin material that dosage is maximum in tanning production, and the important chemical materials in leather processing procedure
One of.It can lubricate leather fiber, prevent that leather is stiff, ftractures, and and can enough makes 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, its type and quantity is also increasing year by year, belongs 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 assign leather good hydrophobicity and fillibility, so as to have stuffing and filling effect, add
Fat effect is permanent, leather is kept soft, plentiful, flexible for a long time, and possesses 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, there is positive meaning to improving resultant leather quality.But at present, synthetic fat liquor species is seldom, and performance is single, majority be all with
Low middle-grade fatting agent based on natural oil and its modifier.
