Embodiment 5

[0046] The powdered carbon black before granulation is metered and fed into the upper channel of the granulator, and the feeding speed is controlled to be 400g / min. The oil temperature was controlled at 60°C and the flow rate was 40 g / min. When the carbon black enters the granulation section, the granulation water pump is turned on, and the flow rate of the granulation water is controlled at 600g / min. After the granulated carbon black is obtained, it is dried by a drum dryer until the moisture content is qualified.

Embodiment 6

[0048] The powdered carbon black before granulation is metered and fed into the upper channel of the granulator, and the feeding speed is controlled to be 200g / min. The oil temperature was controlled at 60°C and the flow rate was 40 g / min. When the carbon black enters the granulation section, the granulation water pump is turned on, and the flow rate of the granulation water is controlled at 600g / min. After the granulated carbon black is obtained, it is dried by a drum dryer until the moisture content is qualified.

Embodiment 7

[0050] The powdered carbon black before granulation is metered and fed into the upper channel of the granulator, and the feeding speed is controlled to be 100g / min. The metering pump is used to meter and atomize the operating oil or mixed oil, which accounts for 40% of the carbon black mass. The oil temperature was controlled at 60°C and the flow rate was 40 g / min. When the carbon black enters the granulation section, the granulation water pump is turned on, and the flow rate of the granulation water is controlled at 600g / min. After the granulated carbon black is obtained, it is dried by a drum dryer until the moisture content is qualified.

Abstract

The invention discloses a method for preparing oil-containing carbon black particles, which is characterized by comprising the following steps: 1) putting the powdery carbon black into a channel above the granulator; Insert the spray gun on both sides of the channel, and the oil is sprayed into the powdered carbon black through the spray gun and mixed with it; 3) The water is sprayed into the granulator through the water gun, and the same as step 2 ) The obtained powdery carbon black is mixed with the mixture of the oil, and after granulation, the oil-containing carbon black particles can be obtained by drying.

Description

technical field [0001] The present invention relates to a method for preparing carbon black, in particular to a method for preparing oil-containing carbon black particles. [0002] technical background [0003] As the largest reinforcing material for rubber, carbon black plays an indispensable role in tires and rubber products. However, since carbon black is a nano-sized material, adding a large amount of carbon black to rubber will lead to the formation of carbon black particles. The agglomeration between the two will also lead to a large increase in the carbon black gel formed in the rubber compound, which directly affects the processing properties of the compound such as mixing, extrusion, calendering, and injection molding. At present, the most direct adjustment method for processing performance in the rubber industry is to add a certain amount of operating oil to the formula, or to choose oil-extended rubber. But no one chooses to fill the carbon black with oil. [000...
