Abstract

The invention discloses a leather maintenance agent. The leather maintenance agent comprises 30-45 parts by weight of solid resin, 0.1-0.5 part by weight of natural plant essential oil, 1-5 parts by weight of a curing agent, 0.7-6 parts by weight of glycerol and 0.5-2 parts by weight of a surfactant. The leather care agent is wiped on leather, so leather can be softened, the hand feeling is improved, leather is protected from aging, the elasticity of the leather is kept for a long time, and the color and luster of the leather is kept. The leather maintenance agent can emit pleasant fragrance to meet the requirements of different customers, and natural plant essential oil does not have chemical corrosion, so the leather maintenance agent has good protective performance on leather products,and has the effects of sterilization and mildew prevention.

Description

technical field [0001] The invention relates to a leather care agent and the preparation field thereof, in particular to a leather care agent and a preparation method thereof. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning.
