Specific embodiment
It is described in detail below in conjunction with embodiment of the embodiment to the application, but those skilled in the art will
Understand, the following example is merely to illustrate the application, and is not construed as limitation scope of the present application.It is not specified in embodiment specific
Condition person carries out according to conventional conditions or manufacturer's recommended conditions.Reagents or instruments used without specified manufacturer is
The conventional products that can be obtained by commercially available purchase.
In practice, acetylene cracking temperature is substantially at 1400 DEG C or more.By carrying out acetylene absolutely in preceding cleavage temperature
Oxygen cracks and obtains acetylene carbon black.This reaction temperature (cracking temperature) determines that acetylene carbon black is that one kind is easier to adhesion, is not easy
The material of dispersion, and size is uneven between the individual particles of acetylene carbon black, it is widely different.This is resulted in actual use
Acetylene carbon black material uniformly can not be combined very much with other materials, greatly reduce the electric conductivity, thermally conductive of composite material
Performance.
To find out its cause, inventor thinks that the small primary partical of acetylene carbon black, large specific surface area, surface free energy are high, therefore
Extremely strong autohemagglutination power is shown between carbon black particle, in addition the polarity on acetylene carbon black surface and nonpolar functional group are all seldom (such as
Oxygen-containing group is less) so that carbon black is very poor with the compatibility of most of polymer, organic solvent and water.And simultaneously because
Carbon blacksurface is mainly made of graphite linings structural carbon, therefore acetylene carbon black generally has good wetting to nonpolar solvents such as benzene
Performance, and the wettability in water isopolarity solvent is poor.This is unfavorable for the dispersion of carbon black in water, to improve its performance,
It then needs to be changed its polarity and granulation uniformity.
In order to improve the dispersibility of acetylene carbon black, in some schemes known for inventor, by control reaction temperature to drop
Low agglomeration.Although reducing reunion to a certain extent by scheme above-mentioned, also cause to occur lysis efficiency reduce,
The defects of product parameters are not easy to control, degree of graphitization reductions, electric conductivity decline, imbibition, oil absorption capacity decline.
In view of this, inventors herein proposing a kind of new scheme.Point of the improvement acetylene carbon black provided in the application example
The technique for dissipating property, also helping makes acetylene black carbon particles become uniform.
Above-mentioned technique is provided in this example in the method for acetylene carbon black modification.In the application, the modification
Method acetylene carbon black is adjusted from microcosmic angle, so that modified acetylene carbon black is had both hydrophily and lipophilic characteristic.It should
The method of modification can repair the defect of acetylene carbon black primary particle, adjust acetylene carbon black in different systems (polarity, non-pole
Property) dispersibility.
For from principle, the principle that acetylene carbon black is transformed in the method that the application example provides is: by hydridization tune
The polarity and granulation uniformity of whole carbon black.That is, it is surface modified to acetylene carbon black using hydridization method, reduce contact will pass through
Angle (increasing hydrophilic radical by carbon blacksurface to realize) promotes the hydrophily of acetylene carbon black.Meanwhile this method is also in acetylene charcoal
Black surface increases oxygen-containing group, and promotes Zeta potential value because of the use of oxygen-containing group, the acetylene charcoal after making modification
It is black be easier to dispersion, dispersion stabilization it is higher.In addition, modified acetylene carbon black also has the property that the hydrophily of carbon black is got over
Good, then its contact angle is better.In view of acetylene carbon black itself has relatively good lipophilicity, therefore to its surface modified master
It is to improve hydrophily.
Illustratively, the method for acetylene carbon black modification includes: to carry out hydridization processing in acetylene charcoal to acetylene carbon black
Black surface increases hydrophilic radical to make acetylene carbon black constitute amphiphilic material.In other words, containing due to acetylene carbon black surface
Oxygen functional group is less, fugitive constituent is low, the polarity on surface is smaller, while granulation uniformity is bad, to be unfavorable for carbon black in water material
It is evenly dispersed in Material system.To improve its performance, hydridization processing is carried out to it in the application example, changes its surface polarity simultaneously
Improve its particle uniformity.Hydridization treated carbon black oxygen content increases, pH value reduces, the hydrophily oxygen-containing functional group on surface
(such as carboxyl, hydroxyl) increases, and granulation uniformity tends to concentrate, therefore is easily dispersed in aqueous dispersion, moreover it is possible to keep length
Long dispersion stabilization.
As the first implementation, hydridization processing includes: in acetylene during cracking in pyrolysis furnace, to splitting
It solves and surface modified dose is added in furnace.During acetylene cracks, surface modified dose also assists in and reacted
Journey.Surface modified dose is integrated to acetylene carbon black surface, to realize the hybrid modification to acetylene carbon black.
Wherein, it is capable of providing hydrophilic radical above-mentioned for surface modified dose.In different examples, surface modified
Agent can use different components as requested.In some examples, surface modified dose is gas；In other examples,
Surface modified dose is liquid；In some other examples, surface modified dose is mixture of gas and liquid.It can replace
Dai Di, in the example of part, surface modified dose is selected as nitrogenous compound, oxygenatedchemicals and hydrogen-containing compound
Mixture.For example, surface modified dose includes carbon dioxide, carbon monoxide, hydrogen, ammonia and hydrogen peroxide.
In view of above surface modified dose, the oxygen content after acetylene carbon black hydridization be will increase, and carboxyl, hydroxyl group also can
With increasing, and these groups are hydrophilic.With the increase of surface hydridization, carbon blacksurface hydrophilic radical will increase on year-on-year basis
It is more, so that acetylene carbon black is changed into amphiphilic material, adds uniform granularity and good spatial distribution.Acetylene carbon black is just
It can achieve the purpose that be easily dispersed uniform stably dispersing degree in different dispersions high.
Generally, anti-to cracking in the ratio selected while acetylene Pintsch process in the first implementation
Answer area that compound (such as CO containing N, H, O is added2、CO、H2、NH3、H2O2/ liquid etc.), carbon blacksurface is modified with hydridization method
Modification.Further, the method for modification includes: to separate to pyrolysis product, then carries out brokenly poly- and purifies again
Processing.Wherein, the aggregating state that cumulative enough opens acetylene carbon black is broken, and association (high-temperature coking, equipment corruption are fallen by purified treatment
Lose, fall off) impurity have particle and the uniform feature of structure while so that acetylene carbon black is kept high-purity, easily dispersion.Example
Such as, surface modified dose is vapor, carbon dioxide and nitrogen, and the dosage of acetylene is surface modified dose of dosage
0.3 times.
It correspondingly, include adding set 201, pyrolysis furnace 202, material point in the acetylene carbon black Preparation equipment for implementing the program
From equipment 203 and poly- purification device 204 is broken, refering to fig. 1.Each equipment is connected by equipment such as pipeline, valve, flanges
It connects.Above each equipment uses equipment known for inventor or commercial equipment.
By implementing the first aforementioned implementation, on the one hand, this method can reduce the nucleation reaction temperature of charcoal, simultaneously
Carbon black pellet growth is terminated in time, so that carbon black pellet be made to become uniform.On the other hand, carbon black pellet surface forms function
Group, so as to improve particle adhesion, forms good spatial distribution.In another aspect, carbon blacksurface can reduce, reversing, lead to
It crosses and increases hydrophilic radical and oxygen-containing group on acetylene carbon black surface, acetylene carbon black finished product is made to reach amphiphilic (oleophylic, hydrophily).
It is not surface modified modified acetylene carbon black and passes through itself and liquid with the hydrophily that have passed through surface modified acetylene carbon black
The difference of contact angle between body is indicated by Fig. 2A and Fig. 2 B, and is connect what the different multiple test detections of sample progress obtained
Feeler (uses optical contact angle measuring instrument, the measurement of throughput supreme people's court.) comparison is as shown in table 1.Wherein, part does not carry out surface
The contact angle of the acetylene carbon black of modification is as shown in Figure 2 A；The partial contact that have passed through surface modified acetylene carbon black
Angle is as shown in Figure 2 B.
The contact angle of the different sample acetylene carbon blacks of table 1
In addition, the oxygen-containing group for being formed in acetylene carbon black surface makes acetylene carbon black be capable of forming stable solvation in water
Layer, while the cation in adsorption solvent forms double electrical layers, resulting repulsive force hinders the collision between carbon black pellet
Cohesion.Therefore, increase carbon blacksurface oxygen-containing group, system Zeta potential can be increased, the hydrophily and dispersibility for increasing carbon black (are divided
Dissipate stability).The Zeta potential value of acetylene carbon black whether surface modified (hydridization processing) is as shown in Figure 3A and Figure 3B.
