Problems solved by technology

[0004] It can be seen that when the traditional process is used, the processing of pre-dispersed pigments will have organic solvents, such as toluene and sulfur dioxide, which will cause environmental pollution, and there are defects such as high production costs and many processes, which also seriously restrict the development of the pigment industry.

no. 1 example

[0021] see figure 1 , water-based color chips for artificial leather, made of the following raw materials in parts by mass: primary toner, 1250-5600 parts; styrene-acrylic resin, 2100-3700 parts; ethanolamine, 300 parts; water H 2 O, 5000 copies.

[0022] The primary toner is titanium dioxide or carbon black. The following will be described according to titanium dioxide.

[0023] When preparing artificial leather water-based color chips,

[0024] 1) First weigh: 5000g of water, 300g of ethanolamine, 3700g of styrene-acrylic resin, and 4000g of titanium dioxide. The primary toner here is titanium dioxide.

[0025] 2) Pour 5000g of water into the material tank of the ball mill, and then pour 150g of ethanolamine into the water.

[0026] 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. So put half of the amount here fir...

[0036] When preparing artificial leather water-based color chips,

[0037] 1) First weigh: 5000g of water, 300g of ethanolamine, 3300g of styrene-acrylic resin, and 4400g of titanium dioxide.

[0038] 2) Pour 5000g of water into the material tank of the ball mill, and then pour 150g of ethanolamine into the water.

[0039] 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; while adding the styrene-acrylic resin, slowly add the remaining 150g of ethanolamine into the material tank During the process, the PH value in the material tank is kept between 9 and 10.

[0040] See the first embodiment for the rest of the undescribed parts, and will not repeat them here.

[0042] When preparing artificial leather water-based color chips,

[0043] 1) First weigh: 5000g of water, 300g of ethanolamine, 2900g of styrene-acrylic resin, and 4800g of titanium dioxide.

[0044] 2) Pour 5000g of water into the material tank of the ball mill, then pour 150g of ethanolamine into the water, and keep the pH value in the material tank fluctuating between 9 and 10.

[0045] 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; while adding the styrene-acrylic resin, slowly add the remaining 150g of ethanolamine into the material tank During the process, the PH value in the material tank is kept between 9 and 10.

Abstract

The invention relates to a water-based color chip for artificial leather, which is prepared from the following raw materials in parts by mass: 1250-5600 parts of primary color powder, 2100-3700 parts of styrene-acrylic resin, 300 parts of ethanolamine and 5000 parts of water (H2O). The powder comprises titanium white and carbon black. The preparation method comprises the following steps: weighing the raw materials according to parts by mass: pouring the styrene-acrylic resin, ethanolamine and water into a material cylinder of a ball grinder, and grinding for 5-20 minutes until the styrene-acrylic resin, ethanolamine and water are sufficiently mixed and dissolved, thereby obtaining an emulsion; pouring the primary color powder into the material cylinder, and dispersing by grinding with a ball grinder for 2-2.5 hours until the emulsion and primary color powder are sufficiently mixed, thereby obtaining a slurry; and finally, drying the slurry with a drying machine, thereby obtaining the solid water-based color chip. The invention is convenient for color matching and easy for storage, has the characteristics of favorable repetitiveness and wide application range, and can be dissolved in water-based polyurethane and oil-based polyurethane.

Description

technical field [0001] The invention relates to a water-based color chip for artificial leather and a preparation method thereof. Background technique [0002] At present, the production process of pre-dispersed pigments for artificial leather in China mainly uses traditional kneaders for batching, and then uses three-roller extruders for grinding. This production process is relatively mature. There is also a production process using a single-screw banburying extruder, but this production process is not yet mature and is still in the research and development stage. [0003] The production process of traditional pre-dispersed pigments for artificial leather uses primary toner, carrier and various additives containing toluene and liquid resin. Through the traditional process: firstly, mix the materials with a kneader, heat with an oil-fired boiler, add toluene, and part of the toluene volatilizes. Then the cold grinding is carried out by the hand-controlled roller machine, an...
