Well, the advantages of richness is good, grain is clear.But Oleic acid diethylene glycol dilaurate (R1COOCH2CH2OOCR2) in structure not easily
Sulfated active group, therefore its degree be not high, so that the fat liquor of such leather fat is acidproof, salt tolerant
Less stable, and leather surface in extensive stuffing production process easily produces greasy phenomenon.
Compare Oleic acid diethylene glycol dilaurate, Oleic acid ethylene glycol ester (R1COOCH2CH2OH) in structure contain active group (-
OH), the chemical modifications such as sulphation, sulfonation are easily carried out.But the leather fat by the modified preparation of monoesters, its hydrophilic is too
By force, emulsion is excessively stable, is difficult breakdown of emulsion, causes grease molecules to be difficult to be absorbed by leather fiber, and therefore after leather greasing, grain is not
Enough full, elastic force is not enough.
Also have been reported that the molar ratio by adjusting raw material Oleic acid and ethylene glycol, so that contain Oleic acid in product simultaneously
Ethylene glycol ester and dibasic acid esters, then carry out sulphation modification and prepare a kind of leather fat.Such fatting agent emulsion-stabilizing, plus
Fat function admirable, after leather greasing, surface is plentiful, flexible, no greasy feeling.But the method can only Non-follow control raw material throwing
Material ratio, and in product, monoesters and the mol ratio of dibasic acid esters are then determined by response situation it is impossible to carry out controlling accurately, in time.
