Technical Field

The invention relates to the technical field of leather treatment, in particular to a leather color-lapping and color-mixing treatment agent.

Background

The leather is soft, and the basic reason is that when the leather is made, grease is introduced into the animal skin to form an oil film which covers the surface of the fibers in the skin completely, namely, the surfaces of the fibers in the skin are separated by an oil film with proper thickness, so that the friction force of the movement between the fibers in the leather is equivalent to the friction force of the oil molecules, and the leather is soft. After long-term use, the leather is stained with a lot of stains and moisture, for example, when the leather is hydrolyzed when meeting water or in a high-temperature environment, an oil film is damaged, and grease is volatilized and lost, so that fibers in the leather are bonded with each other, and the leather is hardened and embrittled. Therefore, the leather needs to be periodically decontaminated, the leather is kept clean, and the service life of the leather is prolonged.

The nonionic surfactant is a surfactant whose molecule contains an ether group which does not dissociate in an aqueous solution as a main hydrophilic group, and the surface activity of the surfactant is represented by a neutral molecule. The nonionic surfactant has high surface activity, good solubilization, washing, antistatic, calcium soap dispersion and other performances, small irritation, and excellent wetting and washing functions. The pH value range of the surfactant can be wider than that of the common ionic surfactant, and the surfactant can also be used together with other ionic surfactants, and the surfactant of the system can be improved by adding a small amount of nonionic surfactant into the ionic surfactant. Nonionic surfactants can be classified into polyoxyethylene type, polyhydric alcohol type, alkanolamide type, polyether type, amine oxide type, and the like according to the structure of the hydrophilic group.

The hydrophilic group of the nonionic surfactant used in the product is mainly composed of polyethylene glycol group, i.e., polyoxyethylene group, and the other is composed of polyol (e.g., glycerol, pentaerythritol, sucrose, glucose, sorbitol, etc.).

The product comprises chlorinated liquid wax (synthetic neatsfoot oil), cationic surfactant, nonionic emulsifier, and stabilizer. White or cream-colored milky liquids can be diluted by mixing with cold or hot water in any proportion to form a dispersed and stable emulsion. The emulsion has positive charge, and is suitable for being added in one bath to quickly penetrate into leather and be uniformly distributed during chrome tanning or chrome retanning. The dye is also used for dyeing and greasing and is used as surface greasing after acid fixation, so that finished leather has oily feeling, and fluff has good mercerizing effect; and simultaneously, the combination and fixation of the fatting agent and the dye with the leather can be improved.

The preparation method of the product comprises the following steps: (1) preparing oil phase, mixing oil phase substances such as chlorinated liquid wax and the like uniformly; (2) preparing a water phase, and uniformly mixing a cationic surfactant, a nonionic emulsifier, a stabilizer and water; (3) emulsifying, and slowly adding the oil phase solution into the water phase solution while stirring. The quality standard of the enterprise is as follows: the total oil mass is more than or equal to 60 percent, and the pH value (10 percent emulsion) is 3.5 +/-0.5.

The product is prepared by compounding and emulsifying components such as cation, nonionic surfactant and synthetic neat's foot oil. The grease can be used for greasing crust leather by mixing cold water or hot water in any ratio, and a stable and fine emulsion can be formed, so that the grease is well permeated and uniformly distributed. When used in tanning, can improve the penetration and combination speed of tanning agent, make the tanning effect mild, and the grain surface of the tanned crust leather fine, and simultaneously prevent or reduce the scratch and shrinkage of the grain surface. The effect is also ideal when the chromium is added during retanning. The leather surface modification agent is used in the dyeing and fatliquoring periods, can change the surface charge of leather, is beneficial to the complete absorption of anionic dye and fatliquoring agent, obtains obvious surface fatliquoring effect, and plays roles in fixing and deepening dyeing.

The product can remarkably reduce the surface tension of water, thereby promoting the penetration of various materials to leather fibers in the processing of leather water systems, enhancing the process and processing progress and improving the use effect of various materials; can be added into coating slurry to improve the leveling property of the slurry coating. Has good stability of resisting acid, alkali, hard water and heavy metal salt, and has no adverse effect on chemicals of cation, anion, nonionic, cation or amphoteric. Has no affinity to leather fiber and is easy to clean. Due to good emulsifying capacity, the leather degreasing agent can also be used for degreasing leather.

When the leather bonding color-mixing treatment agent is used, the product stock solution is directly smeared on bonding color-mixing parts of leather, leather-excellent leather and the like for decomposition for 5-10 minutes, and then a soft toothbrush is used for brushing or other objects are used for beating to enable the penetration of the bonding color-mixing parts to accelerate the decomposition of stains. Then the product is coated and kept stand to decompose, and the decomposed stains are wiped off. Such repeated operations may take time to break down the soil, perhaps 1 hour, perhaps several hours, perhaps several days, as long as the soil is not removed by the manipulation with patience until it is completely removed.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
