example 1
[0026] Example 1: 20% of PU resin with a solid content of 30%, 23% of aniline black, 1% of white carbon black, 2% of nitrocellulose, 0.5% of dispersant, 0.5% of leveling agent, 1% of silicone oil feel agent, oil Sensitive additive 1%, cyclohexanone 25%, balance is toluene.
[0027] When the formula product in this example is applied to the leather surface, it is firstly processed by a three-plate printing machine or a scraper or a knife, and then the treated leather surface is put into an oven and dried at 140~150°C to take it out. Finally, the leather surface needs to be kneaded with water and then put into a dry kneading machine at 40°C for 1 hour and then taken out.
[0028] 2. The formula product in this example is suitable for the extra black surface treatment of luggage leather.

[0030] 3. The formula product in this example is suitable for the super black treatment agent on the surface of lambskin leather.
example 3
[0031] Example 3: 25% of PU resin with a solid content of 30%, 25% of aniline black, 1.5% of white carbon black, 1% of dispersant, 0.5% of leveling agent, 1.5% of silicone oil feel agent, and 20% of cyclohexanone , and the balance is toluene.
[0032] Instructions:
[0033] 1. First take an appropriate amount of the product of the present invention and print it on the surface of the synthetic leather that needs to be processed with a tannery three-plate machine. In addition, it can be treated with a scraper or a knife;
[0034] 2. After treatment, put the synthetic leather in an oven and dry it at 140~150°C.

Abstract
The invention relates to a carbon black treating agent for synthetic leather and a preparation method of the carbon black treating agent. The carbon black treating agent is prepared according to the following formula including 18-25 percent by mass of PU (polyurethane) resin with the solid content of 30 percent, 20-25 percent by mass of nigraniline, 1-2 percent by mass of silica, 0.5-1 percent by mass of organosilicon dispersant, 0.5 percent by mass of flatting agent, 1-2 percent by mass of silicone oil feeling agent, 20-25 percent by mass of cyclohexanone and toluene in balancing amount, wherein the flatting agent is modified polysilicone. The invention has the benefits as follows: the carbon black treating agent provided by the invention not only can solve the problem that carbon black treating agents for the synthetic leather generally are not resistant to high temperature and are easy to discolor at high temperature, but also has the advantages of washability, strong tinting strength, purity of blackness and the like, and can give the synthetic leather certain metallic luster and glossy feeling; and the carbon black treating agent is simple in production technology, easy in purchase of raw materials and low in cost and can be directly applied to the later-stage production procedure of the synthetic leather.
Description
technical field [0001] The invention relates to a surface treatment agent for synthetic leather and a preparation method thereof, in particular to a carbon black treatment agent for synthetic leather and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards and the growing desire for "return to nature", leather products have become one of the important high-end consumer goods in life. However, due to the rarity and preciousness of the natural resources of the leather, the products of the synthetic leather industry must move closer and develop towards the real leather, not only to achieve the visual and tactile properties of the leather, but also the physical and mechanical strength and chemical resistance. Therefore, the development of artificial leather on the surface of leather Treatment is the main research direction of leather chemical enterprises. The inventive product carbon black treatment agent is on...
