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 , the artificial leather water-based white color chip is made of the following raw materials in parts by mass: titanium dioxide, 4000-5600 parts; styrene-acrylic resin, 2100-3700 parts; ethanolamine, 300 parts; water H2O, 5000 parts.

[0019] When preparing artificial leather water-based white color chips,

[0020] 1) First weigh: 5000g of water, 300g of ethanolamine, 3700g of styrene-acrylic resin, and 4000g of titanium dioxide.

[0021] 2) Pour 5000g of water into the material tank of the ball mill, and then pour 150g 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. Therefore, half of the amount can be put in here first.

[0023] 3) Slowly pour the styrene-acrylic resin into the material tank of the ball mill, and start the ball mill to stir at the same time...

Abstract

The invention discloses an aqueous white color chip for artificial leather. The color chip is characterized by being prepared from the following raw materials in part by mass: 4,000 to 5,600 parts of titanium white, 2,100 to 3,700 parts of styrene-acrylic resin, 300 parts of ethanolamine, and 5,000 parts of water (H2O). A preparation method comprises the following steps of: weighing the raw materials according to the mass proportion; pouring the styrene-acrylic resin, the ethanolamine and the water into a material cylinder of a ball mill, and grinding for 5 to 20 minutes to ensure that the raw materials are fully mixed and dissolved to obtain emulsion; pouring the titanium white into the material cylinder, grinding for 2 to 2.5 hours by the ball mill, and dispersing to ensure that the emulsion and the titanium white are fully mixed to obtain paste; and finally, drying the paste by a dryer to obtain the solid aqueous white color chip. The aqueous white color chip is easy to package andstore, and also has the characteristics of good environment friendliness, good color development performance, easiness in color mixing, high repeatability and broad applicable scope.

Description

technical field [0001] The invention relates to an artificial leather water-based white color chip 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 solv...
