Description

Technical field

[0001] The invention belongs to the technical field of leather chemical industry, and particularly relates to a compound type leather fatliquor containing phosphorylated vegetable oil and a preparation method thereof. Background technique

[0002] Fatliquor is the most used leather chemical material in leather production, and it is also one of the important chemical materials in leather processing. It can not only lubricate the leather fiber, prevent the leather from stiffness and cracking, but also make the leather have corresponding toughness and softness, and maintain its strength. It is an important factor affecting the quality and performance of the leather. In recent years, phosphate fatliquors have become a hot spot in the development of new fatliquors due to their excellent performance. The phosphate active group contained in the molecular structure of this type of fatliquor can enter the leather to interact with the amino group on ...
