Problems solved by technology

Existing leather cleaners are mainly composed of detergents and solvents, which have certain effects on leather such as decontamination, descaling, degreasing, and stain removal. However, after cleaning colored leather, there are more or less dyes or pigments. The phenomenon of being dissolved, which causes the color of colored leather to fade or become lighter and older
In the case of dyes or pigments with good color fastness, the color fading phenomenon of a single wash is usually negligible to the naked eye and does not affect the overall color of the colored leather; but when the washing frequency is high, or the number of washings has accumulated to a certain number At this time, the colored leather will lose its overall color or become lighter in color and become old until the leather is washed and scrapped
Although old colored leather can be refurbished, after a little more refurbishment, a thick coating will be accumulated on the leather surface, thus losing the original grain style, just like artificial leather, and The skin becomes thicker and harder, or even scrapped

preparation example Construction

[0044] The silicone oil compound is preferably one or more of alkyl silicone oil, amino silicone oil, dimethyl silicone oil, fluorine-containing silicone oil and polyether modified silicone oil, wherein dimethyl silicone oil is also called organic silicone oil, silicone oil, etc. It is a kind of polyorganosiloxane with chain structure with different degrees of polymerization. Its preparation method includes: adding water and hydrolyzing dimethyl dichlorosilane to obtain the initial polycondensation ring body, the ring body is cracked and rectified to obtain the lower ring body, and then Mix and telomerize the ring body, head-capping agent and catalyst to obtain mixtures with different degrees of polymerization, and remove the low boilers by distillation under reduced pressure to obtain simethicone. The simethicone oil, such as SILANOL SF9188 and SILANOL LSF9103, generally has a refractive index of 1.40-1.45; the refractive index of the fluorine-containing silicone oil is genera...

Embodiment 1

[0068] Take by weighing the sodium dodecylbenzenesulfonate detergent of 5 weight parts, the chitosan of 98 weight parts, the casein film-forming agent of 95 weight parts, the water of 81 weight parts and the fixing agent Y of 2 weight parts;

[0069] The above-mentioned raw materials are mixed under the condition of temperature of 30° C. to obtain a color-enhancing cleaning agent composition for colored leather.

[0070] The color-enhancing cleaning agent composition for colored leather is used to spray red, yellow, blue, purple and black colored leather to be washed respectively. After 10 treatments, the color of the washed colored leather is dark red, dark yellow and dark blue. blue, dark purple and black.

Embodiment 2

[0075] Weigh 95 parts by weight of nonylphenol polyoxyethylene ether detergent, 2 parts by weight of rare earth product CR-1, 5 parts by weight of casein film-forming agent, 1 part by weight of ethanol and 98 parts by weight of color-fixing agent Y ;

[0076] The above-mentioned raw materials are mixed under the condition of temperature of 50° C. to obtain a color-enhancing cleaning agent composition for colored leather.

[0077] Using the colored leather color-enhancing cleaning agent composition to wipe red, yellow, blue, purple and black colored leather to be washed respectively, after 10 treatments, the color of the washed colored leather is dark red, brilliant yellow, dark blue , deep purple and black.

Abstract

The invention provides a colored leather hyperchromic / cleaning agent composite, which comprises the following raw materials in parts by weight: 5-95 parts of leather cleaning agent, 2-98 parts of darkening agent, 5-95 parts of film forming agent, 1-81 parts of solvent and 2-98 parts of dye-fixing agent, wherein the darkening agent is one or more of chitin, chitosan, silicone oil compounds, rare earth and resin (refractive index: less than 1.5). According to the invention, various auxiliary materials such as the darkening agent and the dye-fixing agent are added into the leather cleaning agent so as to obtain the colored leather hyperchromic / cleaning agent composite; and by using the composite, the original colors of colored leathers after being cleaned are fixed, and darkened, thereby achieving an effect of always keeping fresh through regular cleaning. The invention also provides a method for preparing the colored leather hyperchromic / cleaning agent composite.

Description

technical field [0001] The invention relates to the technical field of leather cleaning, in particular to a color-enhancing cleaning agent composition for colored leather 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 tannin. It has natural grain and luster, and feels comfortable. It includes leather for daily use, such as for making clothing and bags. Leather for articles of use, national defense leather, industrial and agricultural leather, cultural and sporting goods leather, etc. In leather applications such as household leather, colored leather dyed with dyes or pigments is often widely used in order to achieve decorative effects and other purposes. [0003] At present, leather cleaners are usually used to clean leather. Existing leather cleaners are mainly composed of detergents and solvents, which have certain effects on leath...
