Description

[0001] APPARATUS FOR MANUFACTURING CARBON BLACK [0002]

The present invention relates to a carbon black manufacturing apparatus capable of continuously carrying out surface treatment for carbon black together with production of raw carbon black by having a reactor capable of uniform oxidation treatment to carbon black.

Carbon black means aggregates of very fine spherical particles obtained by incomplete combustion of hydrocarbons or carbon-containing compounds. These carbon blacks form primary particles in the reaction furnace and are fused to each other to form grapevine-like primary aggregates. Thus, the degree of development of the primary aggregate is called the structure.

High color commercially available carbon black is mainly used as a black coloring agent for industrial paints, coatings, colorants for plastics and fibers, various types of printed materials, and inks for newspaper printing. In addition, high color commercial carbon black is widely used as a conductive material for electronic parts throughout the industrial sector.

At this time, the carbon black affects the quality of the ink or the paint depending on the physical properties of the carbon black itself. Physical properties that have an important influence on the quality of the ink or paint include specific surface area, structure, particle size, and volatile content. Therefore, in order to produce a high-color carbon black, the basic colloidal properties of carbon black such as specific surface area, structure, particle size and surface functional group should be controlled.

The degree of structural development varies depending on the grade. The tensile stress and extrusion characteristics when blended in rubber, the dispersibility in the case of mixing with ink and automobile paint and resin, the factor affecting blackness, viscosity, to be. The structure consists of agglomerate which is permanently fused and secondary agglomerate by interaction of van der waals force. In fact, the degree of involvement in function of ink, paint, The former is judged to be dominant.

As the degree of structural development of carbon black increases, the degree of blackness and tint decreases, but the demand and viscosity of dispersion and medium are increased.

At this time, the smaller the particle size of the carbon black, the higher the blackness, the tinting strength, the ultraviolet shielding and absorption power, and the dispersibility are decreased. Also, an increase in porosity indicates an increase in the demand and viscosity of the medium.

Also, as the particle size becomes smaller, the blackness and coloring power are better, but the dispersibility is deteriorated and the workability is lowered. When the structure is developed, the dispersibility is improved, but the blackness and tinting strength tend to be lowered. Therefore, if high-color carbon black is prepared by controlling only these two characteristics, there is a limit to its use due to the problem of dispersibility and processability.

In general, the main constituent element of carbon black is hydrogen or hydrogen contained in hydrocarbons which are raw materials of carbon black, and oxygen which is added in the decomposition reaction process and the collection process. Here, it is known that most of hydrogen and carbon exist at the surface of the particle, that is, at the end of the crystallite.

Generally, a liquid oxidation method is used as a conventional method for producing carbon black.

Such a liquid phase oxidation method is a method in which carbon black is put in an oxidizing aqueous solution such as nitric acid, sulfuric acid, chlorate, and percarbonate, followed by stirring and mixing. At this time, at least one acidic solution of nitric acid and sulfuric acid is deposited on the surface of the carbon black for a period of about 10 to 48 hours, and then it is washed with distilled water to inject a polar functional group for increasing the dispersibility, and thoroughly dried in an oven.

Such a liquid phase oxidation process is carried out by introducing a post-treatment process of a final product of carbon black, which is a batch type, which lowers the process stability and lowers the uniformity of the product, Causing problems.

An object of the present invention is to provide a carbon black producing apparatus capable of continuously carrying out surface treatment for carbon black together with production of carbon black.

It is still another object of the present invention to provide a carbon black producing apparatus having a reactor capable of performing uniform surface treatment on carbon black.

FIG. 2 is a schematic view showing a case where a fourth transfer pipe applied to the region A of FIG. 1 is provided as a transfer type reactor. Hereinafter, the fourth transfer piping and the transfer type reactor will be described in the same manner.

Referring to Fig. 2, a fourth transfer pipe 164 connecting the outlet of the second reactor (130 in Fig. 1) and the inlet of the pelletizer (140 in Fig. 1) is connected to the carbon black mixture To the outlet 164b while performing surface treatment on the carbon black in the mixture. To this end, the fourth transfer piping 164 is characterized by simultaneously including the surface treatment means together with the conveying means of the carbon black.

The ozone generator supplies oxygen from the oxygen supplier to generate ozone, and the generated ozone is supplied to the fourth transfer pipe 164 in a mixed gas state mixed with oxygen.

In the ozone generator, for example, ozone can be generated through plasma discharge such as high voltage arc discharge using air or oxygen as a main raw material. Oxygen is used to separate oxygen only after compressing air with a compressor.

Another example of generating ozone may be a silent discharge such as a corona discharge. When a high voltage (6 kV to 15 kV) is applied to the electrode by sandwiching a dielectric such as glass or ceramics between electrodes and blowing air or oxygen, ozone is generated in the discharge space by the following reaction.

The feeding rate of the mixed gas can be adjusted in order to prevent the carbon black from being blown due to the flow velocity of the gas when the mixed gas is introduced into the fourth transfer pipe 164. The concentration of the mixed gas and the charging volume per hour can be adjusted according to the bulk density of the carbon black in the fourth transfer pipe 164.

Specifically, the mixed gas may be introduced at a concentration of 15 g / m ³ to 200 g / m ³ , and the feeding rate may be adjusted according to the internal volume of the fourth transfer pipe 164. For example, the mixed gas may be introduced at a rate of 5 L / min to 50 L / min when the internal volume of the fourth transfer pipe 164 is 70 L. It is possible to increase the oxidation efficiency for the carbon black by introducing the mixed gas at the inflow rate within the above-mentioned numerical range.

The fourth transfer pipe 164 used for oxidizing the carbon black herein may have an ozone gas inlet 164d and an ozone gas outlet (not shown).

The ozone gas inlet 164d and the ozone gas outlet may be provided on both sides of the fourth transfer pipe 164 or entirely along the extending direction of the fourth transfer pipe 164.

When the mixed gas is injected into the fourth transfer pipe 164, it contacts with the carbon black supplied into the fourth transfer pipe 164, where the ozone in the mixed gas reacts with the carbon black so that the carbon black becomes hydrophilic It is reduced to oxygen and discharged through the ozone gas outlet.

At this time, the surface modification of the carbon black is to introduce a polar functional group capable of hindering the transfer of electrons to the surface of the carbon black. The type of the polar functional group is not particularly limited, and examples thereof include an amino group, a halogen group, An amide group, an aldehyde group, a ketone group, a carboxyl group, an ester group, a hydroxyl group, an acid anhydride group, an acyl halide group, a cyano group and an azole group in the presence of an acid catalyst, a phosphonium group, a phosphoric group, a thiol group, .
