Embodiment 1

[0025] High-speed dispersing machine production:

[0026] Add 69KG of dimethylformamide (DMF) solution, 1.0KG of low degree of polymerization fatty alcohol polyoxyethylene ether emulsifier, 3.0KG of triethanolamine, and 15.0KG of polyurethane resin, and stir evenly to form a pre-dispersion solvent.

[0027] Add 2.0KG of matting powder TS-100 under stirring. When adding matting powder, due to the low density of matting powder, the powder is easy to float. Therefore, it needs to be added very slowly. The speed of adding matting powder is 100 g / min. The stirring speed is 500 rpm, so that the pre-dispersion liquid can bring all the added matting powder into the dispersion liquid, so as to ensure the cleanness of the production environment and the accuracy of the formula. After adding all the matting powder, stir for 30 minutes at 1500 rpm to ensure complete dispersion of the matting powder.

[0028] Add 10KG of nigrosine pigment (PB1) under stirring, the nigrosine addition speed ...

Embodiment 2

[0030] High-speed dispersing machine production:

[0031] Add 48.5KG of dimethylformamide (DMF) solution, 1.5KG of low degree of polymerization fatty alcohol polyoxyethylene ether emulsifier, 6KG of triethanolamine, and 25KG of polyurethane resin, and stir evenly to form a pre-dispersion solvent.

[0032] Add 4.0KG matting powder TS-100 under stirring. When adding matting powder, due to the low density of matting powder, the powder is easy to float. Therefore, it needs to be added very slowly. The speed of adding matting powder is 100 g / min. The stirring speed is 500 rpm, so that the pre-dispersion liquid can bring all the added matting powder into the dispersion liquid, so as to ensure the cleanness of the production environment and the accuracy of the formula. After adding all the matting powder, stir for 30 minutes at 1500 rpm to ensure complete dispersion of the matting powder.

[0035] High-speed dispersing machine production:

[0036] Add 26KG of dimethylformamide (DMF) solution, 2.0KG of low degree of polymerization fatty alcohol polyoxyethylene ether emulsifier, 9.0KG of triethanolamine, and 35.0KG of polyurethane resin, and stir evenly to form a pre-dispersion solvent.

[0037] Add 8.0KG matting powder TS-100 under stirring. When adding matting powder, due to the low density of matting powder, the powder is easy to float. Therefore, it needs to be added very slowly. The speed of adding matting powder is 100 g / min. The stirring speed is 500 rpm, so that the pre-dispersion liquid can bring all the added matting powder into the dispersion liquid, so as to ensure the cleanness of the production environment and the accuracy of the formula.

Abstract

The invention relates to a synthetic leather surface treatment agent, in particular to a fog and black surface treatment agent applying to a synthetic leather rear section and a preparation method thereof. The fog and black surface treatment agent applying to a synthetic leather rear section comprises the following components by weight percent: 10-25% of aniline black pigment, 1.0-3. 0% of fatty alcohol polyoxyethylene ether, 3-12% of triethanolamine, 15-45% of polyurethane resin, 2-8% of light extinction powder and the balance of dimethylformamide. Using the synthetic leather rear section product treated by the invention, the product of the invention has unparalleled degree of fog and black, and the color characterization of fog and black likes a black hole; and the product treated by the invention has a surface with particular bump effect, and is matched with a super black component in the slurry of the invention, so that very small amount of incident light is reflected, therefore, the visual effect is super fog and super black.

Description

technical field [0001] The invention relates to a synthetic leather surface treatment agent, in particular to a matte black surface treatment agent applied to the back section of synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather is a kind of artificial leather, which is produced from PU resin and non-woven fabrics. Synthetic leather is generally divided into wet method, dry method and post-production process according to the production process. The synthetic leather produced by the wet method is the basic substrate of synthetic leather. The synthetic leather that can be put into daily use is made on the surface of the wet synthetic leather through dry method and post-embossing process. finished product. Traditionally, except for the high-fog and high-black effect of wet-process products made by sanding, other dry-process or post-processing products cannot obtain high-fog and high-black effects, making synthetic leather prod...
