Description
Technical field
The utility model relates to a kind of nano carbon black color paste preparation facilities that is applicable to Neutral writing ink.
Background technology
Carbon black is the fines that produces through incomplete combustion with carbon raw material (being mainly oil).Outward appearance is the particulate or the meal of ater.
Carbon black has following characteristics when being used for gel ink pen with the manufacturing of ink as tinting material:
1. carbon black is best black pigment.
2. carbon black almost is the most cheap pigment.
3. carbon black is tinting strength and the strongest pigment of opacifying power.
4. sooty colourity is neutral on the visual perception.
5. carbon black has the good characteristics of weather resistance, is the most stable pigment, heat-resisting, chemicals-resistant, fast light.
6. the depth of carbon black color, the fineness of particle, the size of proportion, all different and variant with raw materials used and manufacture method.
As a kind of pigment, carbon black is widely used in ink and mill base is made the field.Continuous development along with social scientific and technological level; particularly along with the raising of environmental protection requirement; in mill base, use a lot of solvents in use to be restricted, therefore in ink and mill base manufacturing field, make aqueous color paste and progressively replace the main selection that the solvent-borne type mill base becomes people.Carbon black stably is dispersed in the water, needs to improve the sooty hydrophilicity, therefore carbon black is carried out modification becomes people's research with the needs that adapt to aqueous systems stability a hot subject.
Vapour phase oxidation process is the method that world today's colour carbon black surface oxidation modified industry production is generally adopted.Gaseous oxidation is often used oxidizing gas such as air, oxygen, oxynitrides and ozone etc. that carbon black is carried out the surface oxidation modification and is handled.With gases such as air, oxygen is that oxygenant carries out the product that the gaseous oxidation carbon black obtains, its surface oxygen functional group content is relatively low, major cause is that oxidizing reaction generally will carried out more than 400 ℃, and the part oxygen-containing functional group that is under this temperature is unstable, decomposes to generate CO and CO
2Therefore, with gases such as air, oxygen be oxygenant come oxygenated black method sill stop using.Equally, be oxygenant with the oxynitrides, because defectives such as source of the gas restriction, cost height and environmental pollution also seldom adopt.
Ozone is one of the strongest known oxygenant, is only second to fluorine, can the most organism of oxidation, inorganics.The strong and weak contrast of ozone and other oxidizing substance oxidisability is as follows: fluorine＞hydroxide radical＞ozone＞hydrogen peroxide＞MnO4＞dioxide peroxide＞hypochlorous acid＞chlorine＞oxygen, the ozone stable extreme difference, can be decomposed into oxygen voluntarily at normal temperatures, the transformation period of the following ozone of 1% concentration in air (normal temperature and pressure) is about half hour, rising with temperature, decomposition rate is accelerated, and can transfer oxygen immediately to when temperature reaches 270 ℃ of high temperature.With ozone is oxygenant; gas source is convenient, oxidation efficiency is high, reaction conditions is gentle (under the room temperature), low cost and other advantages because of having; for the world today generally uses, do not have residuals to exist soon owing to it decomposes, so ozonation technology help environment protection.Calendar year 2001, Lu of chemical industry metallurgical institute of Chinese Academy of Sciences cdear, people such as Wang Zhaolin, Li Hongzhong carry out the applied research of ozone in ultra-fine carbon black surface modification, carried out in fluidized-bed, utilizing ozone under different condition, carbon black to be carried out the experiment of surface modification, all be better than non-oxide carbon black in many aspects through the character of the oxygenated black of ozonize.But also there is certain defective in the fluidization of oxidizing carbon black through ozone, and the oxidizing carbon black through ozone fluidization is the gas-solid two phase reaction, and ozone utilization rate is lower, and the sooty oxidation efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of carbon black oxidation efficiency height, carbon black pellet from the good nano carbon black color paste preparation facilities that is applicable to Neutral writing ink of dispersing property.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of nano carbon black color paste preparation facilities that is applicable to Neutral writing ink, comprise reactor, ozonizer, ultramicro air bubble ceramic diffusers, material agitation cycle mechanism, the ultramicro air bubble ceramic diffusers is arranged on the bottom of reactor, the ozone outlet of ozonizer is connected by the inlet mouth of pipeline with the ultramicro air bubble ceramic diffusers, is provided with material agitation cycle mechanism in the reactor.
Improvement of the technical scheme can also comprise tail gas absorbing mechanism, and the top of reactor is provided with exhaust port, and exhaust port is connected with tail gas absorbing mechanism by pipeline.
The beneficial effects of the utility model are: because the bottom of reactor is provided with the ultramicro air bubble ceramic diffusers, the ozone that ozonizer produces is through the ultramicro air bubble ceramic diffusers, can produce diameter and be the bubble about 100 microns, it is long-pending that the generation of microbubble has greatly increased reacted surface, improved the transfer rate of ozone, in less space, have higher efficient, thereby improved the sooty oxidation efficiency greatly; Ozone oxidation reaction in the utility model carbon black color paste preparation facilities can carry out in gas-liquid-solid three-phase, the utilization ratio of ozone is higher, utilize the ultramicro air bubble method simultaneously, can obviously improve the mass-transfer efficiency of ozone in liquid, can prepare can be in aqueous systems self-dispersed oxygenated black product, thereby form the particle diameter range scale and be 150 nanometers with interior carbon black pellet, therefore improved greatly carbon black pellet from dispersing property.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
