Description
Technical field
The present invention relates to black carbon technology field, it is related to a kind of method for improving carbon black dispersion.
Background technology
Carbon black is hydrocarbons through imperfect combustion or is cracked to form.Carbon black is widely used, except being mended for rubber
It is strong outer, it may also be used for other materials, such as coating, paint, ink, ink powder, electronic product, plastics, fiber, electricity
Pond etc., coloring, anti-ultraviolet ageing needed for imparting product, antistatic or conductivity energy.
Carbon black is as a kind of typical nano material, and primary partical size is small (generally<100nm), surface can be high, pole
Larger particle is easily gathered into, it is difficult to be stably dispersed in different systems, giving full play to for carbon black performance, shadow is limited
The quality and performance to downstream product are rung, the big bottleneck applied as carbon black.The scattered of carbon black is largely determined by three
Factor：Characteristic, the type of carrier or decentralized medium, dispersing technology and the dispersing apparatus of carbon black in itself.In kind of carbon black
It is main at present to be handled by adding dispersant-coated, grafting or carrying out Strong oxdiative to improve carbon black in the case of necessarily
Dispersive property.Dispersant-coated or the general progress under liquid phase of grafting processing, in addition it is also necessary to follow-up drying program so that
Production cost is higher；Strong oxdiative processing is general to use strong acid or ozone, easily causes pollution problem.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of method for improving carbon black dispersion, by charcoal
It is black to be passivated processing and structure regulating, the dispersiveness of carbon black is improved, strengthens the application performance of carbon black.
The technical solution adopted by the present invention is：A kind of method for improving carbon black dispersion, it is characterised in that including following
Step：(1) constitution controller is added in carbon black；(2) carbon black and constitution controller are uniformly mixed；(3)
Compound is carried out micro-nano scattered；(4) fineness of dispersion rank is controlled by grading plant；(5) collect and be classified out
The carbon black come produces polymolecularity carbon black.
As an improvement, carbon black structure controlling agent is nano carbon-base material in step (1).By introducing heterogeneous material
The structure (neck dibutyl phthalate absorption value) of material, on the one hand control carbon black, changes the particle diameter distribution of carbon black, separately
On the one hand the contact area between reduction carbon black and carbon black particle, breaks the agglomeration balance between single carbon black fine particle, drop
Agglomerating force between low carbon black pellet, improves the dispersive property of carbon black.
As an improvement, the carbon-based material is at least one in CNT, carbon fiber, graphene, carbon black
Kind.
As a preferred embodiment, carbon black structure controlling agent is kaolin, calcium carbonate superfine powder, clay, silicon in step (1)
One or several kinds in diatomaceous earth.
As a preferred embodiment, the mass percent of constitution controller is 1~30% in step (1).Constitution controller adds
Dosage scope is big, on the one hand causes carbon black structure adjustment space big, is conducive to improving dispersiveness, on the other hand also favourable
In control production cost.
As a preferred embodiment, partition size is set in step (4)<10μm.Granularity is arranged on 10 μm can be with
Requirement of the overwhelming majority application to carbon black dispersion is met, it is meticulous to reduce production efficiency, increase production cost.
The present invention is advantageous in that：The carbon black produced using the method disclosed in the present has excellent disperse
Property, just it may be uniformly dispersed in material without extra addition dispersant or Strong oxdiative processing, and 45 μm tail over
Thing is extremely low, can all pass through 325 eye mesh screens.Carbon black dispersion, simple production process, behaviour are improved using this method
The property made is strong, can popularization and application rapidly.
