Problems solved by technology

However, these organic solvents are harmful substances. During the processing of oily artificial leather, they will be discharged into rivers and atmosphere through water and air, polluting the environment.
Traditional lipophilic color chips can only be dissolved in solvents and solvent-based oily artificial leather finishing agents, but not in water-based artificial leather
[0004] In the current water-based artificial leather market, water-based finishing agents are usually used for coloring. Water-based finishing agents mainly include water-based color pastes and water-based color pastes. Due to the shortcomings of inaccurate toning and poor repeatability in both water-based color pastes and water-based color pastes, resulting in It is difficult to adjust the color of various changes, so that the coloring effect of water-based artificial leather is far inferior to that of existing oil-based artificial leather

[0018] see figure 1 , artificial leather water-based black color chip, made of the following raw materials in parts by mass: carbon black powder, 1250-1750 parts; styrene-acrylic resin, 2750-3250 parts; ethanolamine, 500 parts; water H 2 O, 5000 copies.

[0019] When making water-based black color chips for artificial leather,

[0020] 1) First weigh: 5000g of water, 500g of ethanolamine, 3250g of styrene-acrylic resin, and 1250g of carbon black powder.

[0021] 2) Pour 5000g of water into the material tank of the ball mill, and then pour 250g of ethanolamine into the water.

[0022] Since ethanolamine releases a large amount of heat when it dissolves, ethanolamine can be added in batches during actual preparation to keep the temperature of the material in the tank at room temperature.

[0023] 3) Slowly pour the styrene-acrylic resin into the material tank, and start the ball mill to stir at the same time, the stirring speed of the ball mill is controlled at about 300rpm; ...

Abstract

The invention relates to an aqueous black sheet used for artificial leather, which is characterized by being prepared from the following raw materials in parts by weight: 1250-1750 parts of carbon black powder, 2750-3250 parts of styrene-acrylic resins, 500 parts of ethanolamine and 5000 parts of water (H2O). The preparation method comprises the following steps of: weighing the raw materials according to the parts by weight; then pouring the styrene-acrylic resins, ethanolamine and water into the material cylinder of a ball mill, and milling for 5-20 minutes to fully mix and dissolve and obtain an emulsion; then pouring the carbon black powder into the material cylinder, and milling with the ball mill for 2-2.5 hours to disperse so that the emulsion and the carbon black powder are sufficiently mixed to obtain slurry; and finally drying the slurry using a dryer to obtain the solid black sheet. The aqueous black sheet provided by the invention has the characteristics of simpleness in package and storage, good environmental protection property, good color development performance, convenience in color mixing, good repeatability and wide application range.

Description

technical field [0001] The invention relates to a water-based black color chip for artificial leather and a preparation method thereof. Background technique [0002] Color chip is one of the accessories with high added value and the largest consumption in the production of artificial leather. The annual demand for color chip in the artificial leather industry in my country reaches 45,000 tons. [0003] At present, the traditional artificial leather usually uses organic solvent-based polyurethane resin to add lipophilic color chips as the basic raw material for production. This artificial leather is oily artificial leather. Organic solvents such as dimethylformamide are prepared by bulk polymerization. However, these organic solvents are harmful substances, and during the processing of oily artificial leather, they will be discharged into rivers and the atmosphere through water and air, polluting the environment. Traditional lipophilic color chips can only be dissolved in s...
