Abstract

The invention discloses a preparation method of a leather greasing agent. The method comprises the following steps of proportionally adding sulfonated oil, mineral oil, emulsifiers and solvents into areaction kettle; performing stirring reaction at a certain temperature for a period of time; then, lowering the temperature to a certain value; performing neutralization by neutralizing agents untilthe PH is 6 to 7; adding a certain quantity of preservatives; performing water addition regulation, thus obtaining a product of the leather greasing agent; the effective content of the product is 60+ / -2 percent. The preparation method provided by the invention has the advantages that the environmental-friendly effect is achieved; no waste water and no waste gas are generated; the high-quality product is produced; the clean production is realized; the problem that sulfonated oil monomers cannot be singly applied to the leather greasing; the effect of the sulfonated oil in the leather greasing is improved; the oil lubrication feeling, fullness and particle surface flatness of the leather are improved; meanwhile, the comprehensive economic benefits of the sulfonated oil during application inindustry is also improved.

Description

technical field [0001] The invention belongs to the technical field of leather auxiliary production, and in particular relates to a preparation method of a leather fatliquoring agent. Background technique [0002] From raw hides to leather products, a series of processing procedures have been experienced, among which the fatliquoring process is one of the key processes in tanning. Fatliquor is one of the most used leather chemicals in the process of tanning. It not only affects The fullness, softness and appearance of leather have a great impact on the physical and mechanical properties of leather such as tensile strength and elongation. Even fatliquing can endow the finished leather with waterproof, oil-proof, stain-resistant and flame-retardant , anti-fogging and other special performance. [0003] With the development of the leather industry, there are higher requirements for leather fatliquor. Appropriate selection of fatliquor can change the appearance and inner qualit...
