Problems solved by technology

Water-based products are not long-lasting and have poor affinity with leather. For oil-based products, when long-chain macromolecular components are selected, the oil will not easily penetrate into the leather and cannot repair the hardening inside the leather.

Embodiment 1

[0013] Example 1 adopts the following raw materials in parts by weight: 22 parts of polyether-modified hydrophilic silicone oil, 18 parts of glycerol phosphate, 11 parts of sodium dodecyl sulfonate, 52 parts of ethanol, 8 parts of peregrine, 29 parts of water parts, 1 part of lemon essential oil, follow the steps below:

[0014] (1) Mix and disperse the polyether-modified hydrophilic silicone oil and glycerol phosphate at a speed of 1400 r / min for 12 minutes, and add one-fifth of water, one-third of equal weight, and one-third of ethanol. , continue to stir for 3min;

[0015] (2) Put the sodium dodecyl sulfonate, the remaining ethanol, and the remaining water in another disperser, mix and stir evenly, add the remaining peregrine and lemon essential oil, continue to stir for 5 minutes, and then add step (1) to prepare The mixed emulsion was stirred and dispersed for 5 minutes to obtain a leather softener.

Embodiment 2

[0016] Embodiment 2 adopts the following raw materials in parts by weight: 28 parts of polyether-modified hydrophilic silicone oil, 15 parts of glycerol phosphate, 10.5 parts of sodium dodecyl sulfonate, 55 parts of ethanol, 10.5 parts of peregrine, 30 parts of water ~50 parts, 3 parts of lemon essential oil, follow the steps below:

[0017] (1) Mix and disperse the polyether-modified hydrophilic silicone oil and glycerol phosphate at a speed of 1200 r / min for 15 minutes, and add one-fifth of water, one-third of equal weight, and one-third of ethanol. , continue to stir for 5min;

[0018] (2) Put the sodium dodecyl sulfonate, the remaining ethanol, and the remaining water in another disperser, mix and stir evenly, add the remaining peregrine and lemon essential oil, continue to stir for 6 minutes, and then add step (1) to prepare The mixed emulsion was stirred and dispersed for 5 minutes to obtain a leather softener.

Embodiment 3

[0019] Embodiment 3 adopts the following raw materials in parts by weight: 33 parts of hydrophilic silicone oil modified by polyether, 22 parts of glycerol phosphate, 20 parts of sodium dodecyl sulfonate, 60 parts of ethanol, 15 parts of peregrine, water 50 parts, 2 parts lemon essential oil, follow the steps below:

[0020] (1) Mix and disperse the polyether-modified hydrophilic silicone oil and glycerol phosphate at a speed of 1600 r / min for 10 minutes, and add one-fifth of water, one-third of equal weight, and one-third of ethanol. , continue to stir for 5min;

[0021] (2) Put the sodium dodecyl sulfonate, the remaining ethanol, and the remaining water in another disperser, mix and stir evenly, add the remaining peregrine and lemon essential oil, continue to stir for 8 minutes, and then add step (1) to prepare The mixed emulsion was stirred and dispersed for 5 minutes to obtain a leather softener.

Abstract

The invention discloses a leather softening agent which is prepared from the following raw materials in parts by weight: 15-35 parts of polyether-modified hydrophilic silicon oil, 10-22 parts of phosphoglyceride, 8-25 parts of sodium dodecyl sulfonate, 40-60 parts of alcohol, 5-15 parts of peregal, 30-50 parts of water and 0-3 parts of lemon essential oil. Active ingredients in the leather softening agent disclosed by the invention can enter the leather very well to form hydrogen bond binding with hydrophilic groups on fibers inside the leather, so that the interwoven or hardened fibers are separated or re-formed into sequenced arrangement, the elastic force of the leather is recovered by increasing gaps among the fibers, and the good gas permeability of the leather is supplemented; the active ingredients are bridged inside the leather, so that the fibers inside the leather and grease are firmly connected and the grease inside the leather is not prone to volatilize, and the service life of the leather is prolonged. The leather treated by the leather softening agent disclosed by the invention has characteristics of good air permeability, softness, rebound resilience and a smooth hand feeling.

Description

technical field [0001] The invention relates to a leather treatment agent, in particular to a leather softener, and belongs to the technical field of fine chemicals. Background technique [0002] Leather products have been widely used in people's lives. However, with the use of leather in daily life, due to environmental changes, such as moisture, temperature, etc., the oil or oil film inside the leather will be damaged, and the oil will volatilize, so that the fibers inside the leather will bond to each other, thus Makes the leather hard and brittle. [0003] Products such as leather cleaners, leather conditioners, and leather softeners often soften the leather by refilling the leather with grease. CN 103669002A discloses a kind of raw material including the following raw materials in parts by mass: 20-25 parts of hydroxy silicone oil, 0.5-1 part of acrylic acid, 0.2-0.3 part of polyethylene wax, tetradecamidopropyl hydroxypropyl sulfobetaine 2-5 parts, 30-40 parts of et...
