Problems solved by technology

The fatliquor in the prior art is mostly used in the form of emulsion, and the stability of the fatliquor is an important factor affecting its performance
[0004] Bovine hoof oil is a natural oil that does not contain hydroxyl groups and has strong hydrophobicity. It is mainly triglycerides of 16-acid, 18-acid, oleic acid, and polyene acid. It is one of the high-grade fatliquor , the leather treated with hoof oil fatliquoring agent has excellent characteristics, but the fatliquoring treatment effect of existing hoof oil fatliquoring agent needs to be improved, and there are problems such as storage stability, acid and alkali resistance and metal ion stability.

Abstract

The invention discloses a high-stability leather fat-liquoring agent. The high-stability leather fat-liquoring agent is prepared from the following raw material components in parts by weight: 50 to 60parts of modified neat foot oil, 15 to 25 parts of liquefied beewax, 10 to 18 parts of triethylene glycol, 8 to 15 parts of isotridecyl myristate, 5 to 10 parts of oleyl alcohol polyoxyethylene ether, 5 to 10 parts of coco fatty acid diethanol amide, 1 to 2 parts of vaseline and 65 to 75 parts of water. Meanwhile, the invention discloses a preparation method of the high-stability leather fat-liquoring agent. The fat-liquoring agent disclosed by the invention has good emulsifying ability, excellent permeability and excellent stability performance, and can evenly and deeply permeate into a cutis plate, and has strong natural oil dispersing ability, so that the cutis plate is soft and full, high in elasticity, smooth, mercerized, glossy but not greasy; fat-liquored fur is excellent in ductility, softness and elasticity; the fat-liquoring agent is high in alkali resistance and stability of metal salt ions, and can meet the extremely high requirement of multi-process step-by-step fat liquoring on the performance of the fat-liquoring agent; and the compounded fat-liquoring agent is high in storage stability, can be stored for long, and is stable in property.

Description

technical field [0001] The invention relates to the technical field of leather fatliquor and its preparation, in particular to a highly stable hoof oil leather fatliquor and a preparation method. Background technique [0002] Fatliquoring is an important process in the production and processing of leather from raw hide to finished leather. It is to apply oil directly or in the form of emulsion to the processed leather under certain conditions, so that the lubricating oil components can penetrate into the leather. Between the leather fibers, the mobility between the leather fibers is increased, making the leather soft and resistant to folding, and at the same time avoiding the defects of the leather surface being stiff and easy to break due to the bonding of the leather fibers. The fatliquored leather has good hand feeling and physical and mechanical properties, while reducing the shrinkage of the leather surface and increasing the finished leather area. [0003] Leather fat...
