Abstract
The invention relates to the technical field of leather treatment, in particular to a cleaning agent with coloring and color fixing functions. The cleaning agent with the coloring and color fixing functions is characterized by comprising the following raw materials in parts by weight: 55-65 parts of water, 3-6 parts of surfactant, 25-35 parts of water-soluble organic solvent, 3-8 parts of acrylic resin and 3-8 parts of metal complex dye water, wherein the sum of the contents of all the components is 100 parts; the preparation method comprises the following steps: at normal temperature, respectively weighing water, surfactant, water-soluble organic solvent, acrylic resin and metal complex dye water in sequence, adding into a stirrer, keeping the rotation speed of the stirrer at 40r/min, stirring for 30min, mixing the materials uniformly, and filtering. Compared with the prior art, the leather can be colored and fixed while being cleaned, so that the leather coating process is simplified, and the production efficiency is improved.
Description
Technical Field
The invention relates to the technical field of leather treatment, in particular to a cleaning agent with coloring and color fixing functions.
Background
In the leather finishing process, the leather needs to be subjected to treatment processes such as cleaning and coloring. The existing cleaning agent cleans dirt on the surface of leather, also comprises floating color on the surface, even a part of color coated on the surface of the leather can be cleaned in the cleaning process, and the cleaning function conflicts with coloring and color fixing and cannot be combined in the same process.
Therefore, the cleaning agent with the coloring and color fixing functions is designed, so that the leather can be colored and fixed while being cleaned, the leather coating process is simplified, and the production efficiency is improved.
Disclosure of Invention
The invention provides the cleaning agent with the coloring and color fixing functions for overcoming the defects of the prior art, and the cleaning agent can be used for coloring and color fixing the leather while cleaning, so that the leather coating process is simplified, and the production efficiency is improved.
In order to realize the purpose, the cleaner with the coloring and color fixing functions is designed, and is characterized by comprising the following raw materials in parts by weight: 55-65 parts of water, 3-6 parts of surfactant, 25-35 parts of water-soluble organic solvent, 3-8 parts of acrylic resin and 3-8 parts of metal complex dye water, wherein the sum of the contents of all the components is 100 parts;
the preparation method comprises the following steps: at normal temperature, respectively weighing water, surfactant, water-soluble organic solvent, acrylic resin and metal complex dye water in sequence, adding into a stirrer, keeping the rotation speed of the stirrer at 40r/min, stirring for 30min, mixing the materials uniformly, and filtering.
The acrylic resin is AR 624.
The surfactant is one or more of peregal and OP-15.
The water-soluble organic solvent is one or more of ethanol and ethylene glycol ethyl ether.
The metal complex dye water comprises the following raw materials in parts by weight: 20-25 parts of metal complex dye powder, 50-60 parts of ethanol and 20-30 parts of water, wherein the sum of the contents of the components is 100 parts.
The finishing process of applying the cleaning agent to the black cowhide vamp specifically comprises the following steps:
s1, cleaning: dipping the cleaning agent in sponge or dust-free cloth, ensuring that the cleaning agent is uniformly dispersed in the sponge or dust-free cloth, cleaning the vamp on the vamp in a circling manner, ensuring that the vamp is thoroughly cleaned, and airing or drying after cleaning;
s2, glazing: spraying a polishing material on the vamp by using a compressed air spray gun, spraying the shoe head part, repeating the gun returning twice, pulling the gun to spray the shoe body in a linear mode, and finally returning the gun to the heel part for one to two times;
