Abstract

The invention relates to the technical field of leather and chemical industries, in particular to a silicone-containing amphoteric phosphate fatliquor and a preparation method thereof. The invention aims at providing the silicone-containing amphoteric phosphate fatliquor and the preparation method thereof so as to overcome the problem of affecting the leather color, the physical health of operators and non-ideal fatliquoring effect in the prior art. In order to achieve the purpose, the technical proposal is as follows: the silicone-containing amphoteric phosphate fatliquor is prepared by compounding the following raw materials based on parts by weight: 30-50 parts of polyether-modified polysiloxane phosphobetaine, 20-30 parts of phosphorylated castor oil, 20-40 parts of sulfited fish oil and 0.2-5.0 parts of aliphatic alcohol polyethenoxy ether phosphate. The silicone-containing amphoteric phosphate fatliquor has pale color, does not affect the leather color, has no irritating odor and poses no threat to the physical health of the operators. The fatliquoring leather has the advantages of leather fullness, fine grain surface, elasticity and softness and strong slipperiness; and thefatliquor has good fatliquoring effect.

Description

technical field [0001] The invention relates to the technical field of leather chemical industry, in particular to a silicon-containing amphoteric phosphate fatliquoring agent and a preparation method thereof. Background technique [0002] Fatliquor is one of the important chemical materials in leather production. The use of fatliquoring agent can lubricate the leather fibers and make the leather have corresponding toughness and softness, so it can effectively avoid the stiffness and cracking of the leather and maintain the original strength. At present, the commonly used fatliquor is anionic fatliquor. Taking silicon-containing amphoteric phosphate fatliquor as an example, the existing fatliquor is made of natural oil. The color of the product is deep, and its use will affect the color of leather, and at the same time, it is irritating. Odor affects the health of operators, and the fatliquoring agent has poor bonding and poor hand feeling, and the fatliquoring effect is no...
