Embodiment 1

[0035] Add 18kg of toluene, 5kg of dimethylformamide, 12kg of ethyl acetate, 14kg of butyl acetate, and 4kg of nitrocellulose into the large tank in turn, stir and dissolve completely to obtain a transparent liquid.

[0036] Then add 1kg of fatty acid polyethylene glycol ester dispersant, 0.5kg of polyether siloxane leveling agent, 3kg of polyether modified polysiloxane, 20kg of soybean oil modified alkyd resin, and stir at a low speed. In some cases, add 2.5kg of silica matting powder, 15kg of high-pigment carbon black, and 5kg of color pigments. After adding all the materials, increase the rotation speed and disperse at a high speed for about 20 minutes at a stirring speed of 800-1000 rpm.

[0037] The stirred material is introduced into a vertical sand mill for grinding and dispersing evenly. After passing the inspection, it is packaged to obtain a new type of colored carbon treatment agent for leather.

Embodiment 2

[0039] Add 16kg of toluene, 5kg of dimethylformamide, 12kg of ethyl acetate, 10kg of butyl acetate, and 3kg of nitrocellulose into the large tank in turn, stir and dissolve completely to obtain a transparent liquid.

[0040] Then add 1kg of fatty acid polyethylene glycol ester dispersant, 0.5kg of polyether siloxane leveling agent, 2kg of polyether modified polysiloxane, 25kg of soybean oil modified alkyd resin, and stir at a low speed. In some cases, add 2.5kg of silica matting powder, 18kg of high-pigment carbon black, and 4kg of color pigments. After adding all the materials, increase the rotation speed and disperse at a high speed of 800-1000 rpm for about 20 minutes for later use.

[0041] The stirred material is introduced into a vertical sand mill for grinding and dispersing evenly. After passing the inspection, it is packaged to obtain a new type of colored carbon treatment agent for leather.

Embodiment 3

[0043] Add 15kg of toluene, 4kg of dimethylformamide, 10kg of ethyl acetate, 10kg of butyl acetate, and 2kg of nitrocellulose into a large tank in sequence, stir and dissolve completely to obtain a transparent liquid.

[0044] Add 1kg of fatty acid polyethylene glycol ester dispersant, 0.5kg of polyether siloxane leveling agent, 1.5kg of polyether modified polysiloxane, and 30kg of soybean oil modified alkyd resin in sequence and stir , Add 2kg of silica matting powder, 20kg of high-pigment carbon black, and 3kg of color pigment at low speed. After adding all the materials, increase the rotation speed and disperse at a high speed for about 20 minutes at a stirring speed of 800-1000 rpm.

[0045] The stirred material is introduced into a vertical sand mill for grinding and dispersing evenly. After passing the inspection, it is packaged to obtain a new type of colored carbon treatment agent for leather.

Abstract

The invention discloses a novel color carbon treatment agent for leather and a preparation method thereof, relating to a surface treatment agent for synthetic leather. The color carbon treatment agent disclosed herein comprises 10-40% of alkyd resin, 1-10% of nitro-cotton, 0.5-1% of levelling agent, 1-10% of matting powder, 5-25% of carbon black, 5-25% of color pigment, 30-60% of solvent, 0.5-2% of dispersant, and 1-5% of stripping aid. According to the invention, the problems of dispersion and fineness of the carbon black and color pigment are solved, by adding the color pigment to compound with the carbon black and simultaneously polishing the product, the leather surface presents a synthetic and complete color effect and has a certain metal luster, the formula design is reasonable, the component cooperation is advanced, the product performance is excellent and stable, the technology is advanced, and the operationality is strong.

Description

Technical field: [0001] The invention relates to a surface treatment agent for synthetic leather, in particular to a novel colored carbon treatment agent for leather and a preparation method thereof. Background technique: [0002] Synthetic leather is usually a thin sheet formed by laminating polyurethane resin composition on non-woven fabric, woven fabric or woven fabric. Its structure generally includes a base fabric and a polyurethane resin surface layer attached to the base fabric. The surface layer is mainly used for decoration and to achieve the effect of imitating natural leather. Colored carbon leather treatment agent is a popular synthetic leather, which is used on nubuck and lambskin to increase blackness or other color effects. Moreover, after this treatment agent is polished and polished, the top part of the synthetic leather becomes brighter, and the bottom of the groove has a special fog black effect or other color effects, forming effects such as strong layer...
