Example Embodiment

[0018] Example 1

[0019] The formula of a leather care agent is: 40 parts by weight of solid resin (in which rosin: wood rosin = 1:1), 0.3 parts by weight of natural plant essential oil (lemon essential oil), 3 parts by weight of curing agent (cyanuric acid Tripropylene), 3.5 parts by weight of glycerin, and 1.2 parts by weight of surfactant (sodium cinnamyl sulfate).

[0020] Prepare the leather care agent according to the above formula: put 3.5 parts by weight of glycerin and 40 parts by weight of solid resin into the mixer and mix uniformly, and then heat at 45°C for 1-2h while stirring, the stirring speed is 550rpm, and then Put 3 parts by weight of curing agent and 1.2 parts by weight of surfactant into the mixer, heat up to 65°C, stir at 900 rpm for 1 hour, cool to room temperature, add 0.3 parts by weight of natural plant essential oil, at room temperature Stir evenly to obtain the leather care agent.

Example Embodiment

[0021] Example 2

[0022] The formula of a leather care agent is: 45 parts by weight of solid resin (high oil rosin: hydrogenated rosin = 2:1), 0.1 parts by weight of natural plant essential oil (lavender essential oil), and 1 part by weight of curing agent (butyl acrylate) ), 0.7 parts by weight of glycerin, and 0.5 parts by weight of surfactant (polysorbate).

[0023] Prepare the leather care agent according to the above formula: put 0.7 parts by weight of glycerin and 45 parts by weight of solid resin into the mixer and mix uniformly, and then heat at 40°C for 2h while stirring, the stirring speed is 500rpm, and then Put 1 part by weight of curing agent and 0.5 part by weight of surfactant into the mixer, heat up to 60°C, stir for 1.5h at 800 rpm, cool to room temperature, add 0.1 part by weight of natural plant essential oil, and stir at room temperature The leather care agent can be obtained evenly.

Example Embodiment

[0024] Example 3

[0025] The formula of a leather care agent is: 30 parts by weight of solid resin (dipentene resin), 0.5 parts by weight of natural plant essential oil (clove essential oil: Eucalyptus essential oil = 3: 1), and 5 parts by weight of curing agent ( Tripropylene cyanurate), 6 parts by weight of glycerin, and 2 parts by weight of surfactant (disodium lauroyl amphoteric diacetate).

[0026] Prepare the leather care agent according to the above formula: put 6 parts by weight of glycerin and 30 parts by weight of solid resin into the mixer and mix uniformly, and then heat at 50°C for 1h while stirring, the stirring speed is 600rpm, and then Put 5 parts by weight of curing agent and 2 parts by weight of surfactant into the mixer, heat to 70°C, stir at 1000rpm for 0.5h, cool to room temperature, add 0.5 parts by weight of natural plant essential oil, and stir at room temperature The leather care agent can be obtained evenly.

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. 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. The leather industry covers the main industries such as tanning, shoemaking, leather clothing, leather goods, fur and its products, and supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories. [0003] As people's living standards are getting higher and higher, leather products have gradually entered people's daily lives, and leather products such as leather shoes, leather clothes, and leather bags have b...
