Technical Field

The invention relates to the field of leather care agents and preparation thereof, and particularly relates to a leather care agent and a preparation method thereof.

Background

The leather is animal skin which is obtained by physical and chemical processing such as unhairing, tanning and the like and is denatured and non-perishable. The leather is formed by tightly weaving natural protein fibers in a three-dimensional space, and the surface of the leather is provided with a special grain surface layer which has natural grains and luster and comfortable hand feeling. The leather industry covers the main industries of leather making, shoes making, leather clothing, leather pieces, fur and products thereof and the matching industries of leather chemical industry, leather hardware, leather machinery, auxiliary materials and the like.

With the higher living standard of people, leather products gradually enter the daily life of people, and leather products such as leather shoes, leather clothes, leather bags and the like become popular consumer goods. However, as the use time increases, the grease inside the leather volatilizes or is destroyed, and the leather product becomes hard, the hand feeling deteriorates, and the gloss is lost, thereby affecting the beauty. However, some of the existing leather care agents excessively seek to brighten and polish the leather, and neglect to supplement grease for the leather, so that some leather products are bright and beautiful in surface, and actually have poor air permeability, which seriously affects user experience. Therefore, there is a need to design a novel leather care agent capable of sufficiently supplementing grease to leather. .
