Abstract
The present invention relates to black carbon technology field, it is related to a kind of preparation method of superfine carbon black.By carbon black and dispersant NNO by weight ratio 10：0.05~0.65 abundant mixture is uniform, and mixture is placed in drying plant, is warming up to 120 DEG C~130 DEG C and dries 45 hours, obtain modified carbon black, the modified carbon black after drying is carried out into secondary gas flow crushing, 400 500 mesh are crushed to for the first time；The modified carbon black of 400 500 mesh is crushed to 900 1000 mesh again, modified carbon black powder is obtained.The superfine special carbon black of the present invention, using surfactant, " grafting " is carried out on carbon blacksurface free radical, enable carbon black surface be reduced to it is close with used carrier, the polarity of carbon black is improved, is allowed to mix well with water, as nontoxic water-soluble carbon black products.
Description
Technical field
The present invention relates to black carbon technology field, it is related to a kind of preparation method of superfine carbon black.
Background technology
Industrial carbon black is divided into rubber grade carbon black and extraordinary colour carbon black, and the most of of domestic production are the rubbers for manufacturing tire
Glue carbon black, and extraordinary pigment production of carbon black is then in the starting stage, the Main Ingredients and Appearance of carbon black is carbon, and it is dissolved only in
Organic solvent, such as benzene, dimethylbenzene.These solvents have different degrees of toxicity in use, pollute
Environment, is detrimental to health.Developed country has been forbidden to use, and domestic many industries, which are also all disabled or limited, to be used.Cause
This, develops the environment-friendly type carbon black products using water as solvent, substitutes the carbon black products of organic solvent, is current carbon black materials
The key project of science and technology research and development.
The content of the invention
It is an object of the invention to provide a kind of preparation method of superfine special carbon black, pass through the free radical to carbon blacksurface
It is modified, reduces its surface energy, make it have hydrophily, dispersiveness and phase are obtained through air-flow crushing to required fineness
The excellent carbon black of capacitive.
The technical scheme is that：By carbon black and dispersant NNO by weight ratio 10：0.05~0.65 is fully mixed
With uniform, mixture is placed in drying plant, 120 DEG C~130 DEG C is warming up to and dries 4-5 hours, obtain Modified Activated Carbon
It is black, the modified carbon black after drying is subjected to secondary gas flow crushing, 400-500 mesh is crushed to for the first time；Again by 400-500
Purpose modified carbon black is crushed to 900-1000 mesh, obtains modified carbon black powder.
The superfine special carbon black of the present invention, using surfactant, " grafting " is carried out on carbon blacksurface free radical,
The surface of carbon black is reduced to, the polarity of raising carbon black close with used carrier, be allowed to mix well with water, into
For nontoxic water-soluble carbon black products.
Embodiment
Chemically analyzed in technology aspect, the basic element of ordinary carbon black is carbon, and carbon is insoluble in water,
It is no polarity.And the medium that coating, paint, ink, construction material etc. are used, typically polarized.Root
According to the principles of chemistry, polarity is close, and intermiscibility is better；Conversely, intermiscibility is poorer.So in polarizable medium, non-pole
Property carbon black be difficult to be uniformly distributed therein, and cause the rheological characteristic of product poor, not only the performance of influence product, and
Also it is unfavorable for the processing of product and uses.The present invention increases polar functional group on carbon blacksurface free radical " grafting ",
It is allowed to become water not dispersed into dispersibility.
Using a kind of sulfonate (NNO) type surfactant at a certain temperature, to the free radical of carbon blacksurface
It is modified, reduces its surface energy, enable carbon black close with the surface of water and produce new water ion base, after " grafting "
Carbon black and water have good intermiscibility, and substantially increase properties of product.
Embodiment 1
Carbon black, dispersant NNO, 100 ㎏, 0.5 ㎏ are weighed successively；Its abundant mixture is uniform, be warming up to 120 DEG C~
130 DEG C are dried 4 hours, obtain modified carbon black, and the modified carbon black after drying is carried out into secondary gas flow crushing, the first wheat-middlings
It is broken to 400 mesh；The modified carbon black of 400 mesh is crushed to 900 mesh again, modified carbon black powder is obtained.
Embodiment 2
Carbon black, dispersant NNO, 100 ㎏, 6.5 ㎏ are weighed successively；Its abundant mixture is uniform, be warming up to 120 DEG C~
130 DEG C dry 5 hours, obtain modified carbon black, the modified carbon black after drying are carried out into secondary gas flow crushing, for the first time
It is crushed to 500 mesh；The modified carbon black of 500 mesh is crushed to 1000 mesh again, modified carbon black powder is obtained.
Embodiment 3
Carbon black, dispersant NNO, 100 ㎏, 4.5 ㎏ are weighed successively；Its abundant mixture is uniform, be warming up to 120 DEG C~
130 DEG C dry 5 hours, obtain modified carbon black, the modified carbon black after drying are carried out into secondary gas flow crushing, for the first time
It is crushed to 500 mesh；The modified carbon black of 500 mesh is crushed to 1000 mesh again, modified carbon black powder is obtained.
