Abstract

The invention relates to a tanning agent for horsehide and a horsehide tanning technology adopting the tanning agent. The tanning agent is prepared from diethanolamine, hydrogen peroxide, urea-formaldehyde resin, 2-oxopyrrolidine, dibutyl itaconate, maleic acid, sodium phthalate, carboxybenzaldehyde, di-n-butylamine, fatty aldehyde and diisocyanate. The tanning technology comprises the steps as follows: the horsehide is sequentially treated with procedures including soaking in water, removal of horse meat, softening, tanning and airing. The tanning agent has the good tanning effect on the horsehide in a targeted manner, the procedures can be effectively simplified when the horsehide is tanned with the tanning agent, horse leather can be obtained through treatment of the horsehide with the procedures including soaking in the water, removal of the horse meat, softening, tanning and airing, the tanning procedure has the fat eliminating effect on the horsehide, the tanning technology is effectively simplified, the tanning efficiency is effectively improved, the production cost is effectively reduced, and the prepared horse leather has the good characteristics of being soft, fine, wear-resistant, good in elasticity and the like.

Description

technical field [0001] The invention relates to a tanning agent and a tanning process thereof, in particular to a tanning agent especially suitable for horse hide and the tanning process thereof. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. [0003] The current leather tanning process is relatively complicated. For example, the Chinese invention patent with application number 201310725180.5 provides a goatskin synthetic tanning process. Meat → secondary degreasing → pickling → softening → tanning → neutralization → drying with water → regain moisture and shovel until soft. The tanning process requires multiple processes of immersion in water, degreasing, etc., the p...
