Description
Technical field
The present invention relates to a kind of preparation methods of polymolecularity carbon black, belong to carbon black preparation technical field.
Background technique
Carbon black is a kind of important chemical raw material, with excellent reinforcing, coloring, light resistance, antistatic property and
Ultraviolet-resistent property, and it is abundance, cheap, it has been widely used in rubber, plastics, ink, coating, dry cell and chemical fibre etc.
Many industries.Carbon black is the product of hydrocarbons imperfect combustion or cracking, can be divided into oven process, channel process and hot tearing by production method
Method.Wherein channel black is banned by many countries because yield is very low, environmental pollution is serious, and furnace black, especially oil oven
Method carbon black because yield is high, product quality is easy to control, it is low in the pollution of the environment due to become main kind of carbon black at present.
The main ingredient of carbon black is carbon, so that carbon black is in nonpolarity, it is poor with polar wettability, it is difficult in water point
It dissipates.Currently, in order to improve the self-dispersing and stability of carbon black in water, main preparation methods have oxidation modification, graft modification,
Dispersing agent directly disperses and polymer encapsulation, its essence is introducing or adsorbing hydrophilic radical in hydrophobic carbon blacksurface, makes
There is enough electrostatic repulsions and/or space resistance to prevent from assembling, to obtain stable aqueous carbon black dispersion between carbon black particle
Liquid.It is now recognized that the hydrophily of carbon black is mainly related with the acid functional mass contg of carbon blacksurface, and due to the dissociation of carboxyl
Constant is less than hydroxyl, and therefore, carboxyl disperses to play a major role in water to carbon black, they are capable of forming stable solvent in water
Change layer, while the cation in adsorption solvent forms double electrical layers, the repulsive force of generation can hinder the collision between carbon black pellet
Cohesion.
So far, have many research workers both at home and abroad and engage in carbon black Quality Research, such as coming to the surface for carbon black
Learn activity, form and microstructure and the surface nature of carbon black etc. to various surfactants and polymer carbon blacksurface suction
Attached, dispersion and its system performance have also made more research, but are not fully solved carbon black agglomeration traits again in water-based system yet.
Summary of the invention
The present invention solves the technical problem of: it is poor for current conventional carbon black and wettability, easy in water
It is poly- to be difficult to disperse, and common carbon black modified method cannot be fully solved carbon black in water-based system agglomeration traits again it is scarce
It falls into.The present invention generates carbon black by rapeseed oil imperfect combustion and is deposited on glass infuser inner wall, and scraping is spare, then with rich in amino
The biomass mixed fermentation of acid obtains fermentation liquid, using fermentation liquid to carbon black table under the methane liquid collective effect rich in microorganism
Face is modified, up to polymolecularity carbon black after spray drying.The present invention utilizes the fermentation liquid rich in amino acid modified to carbon blacksurface,
The hydrophilic amino group and carboxyl quantity for increasing carbon blacksurface under the action of microorganism, improve the hydrophily of carbon black, together
When amino acid in carboxylic group can form stable solvated layer in water, while adsorbing the cation in water and forming double electricity
Layer structure, the repulsive force of generation can hinder the collision between carbon black pellet to agglomerate, avoid agglomeration, and carbon black is made to have splendid water
Dispersibility, solves that conventional carbon black is poor with wettability, is easy the carbon black modified method for being difficult to disperse, and common of reuniting in water
It cannot be fully solved the problem of carbon black is reunited again in water-based system again, have broad application prospects.

Bottle scrapes glass infuser inner wall silica aerogel layer with scraper, is put into until the rapeseed oil completely burnout in vial, glass infuser is taken out
It is put into baking oven dry 30~40min at 105~110 DEG C after 20~30min of mortar grinder, obtains hydrocarbon black powder, it is spare;
(2) it weighs 100~200g and climbs rock loach, 50~60g squid palpus out, 120~130g soya bean and 200~300g lotus root piece and be put into
20~30min is crushed in tissue pulverizer and obtains mixture, and mixture is fitted into ceramic pot, the matter such as mixture are added into tank
The deionized water of amount, sealed fermenter after mixing evenly, spontaneous fermentation 20~30 days;
(3) to it is above-mentioned after fermentation, take out fermentation material filtering removal filter residue, filtrate is obtained, by filtrate horizontal centrifugal
Machine is with 2000~3000r/min, 10~15min of revolving speed centrifugal treating, isolated supernatant, then supernatant is put into rotation and is steamed
It sends out in instrument, the 1/3 of concentrated by rotary evaporation to its original volume, obtains kilnitamin concentrate;
(4) with ultrasound point after above-mentioned kilnitamin concentrate and spare hydrocarbon black powder being mixed for 5:1 in mass ratio
Instrument is dissipated with 200~300W, 30~40min of power dispersion, obtains dispersion liquid, measures the methane liquid of the quality such as hydrocarbon black powder, centrifugation 10~
Methane liquid is clarified on the isolated upper layer 15min, then 9 will be fermented at 30~40 DEG C after clarification methane liquid and dispersion liquid mix~
12 days;
(5) to which after fermentation, fermentation material is put into vacuum concentration pot, pressure inside the tank is reduced to 900~1000Pa, is subtracted
Concentrate is obtained after 2~3h of pressure concentration, then will be packed after concentrate spray dryer drying up to polymolecularity carbon black.
The present invention utilizes the fermentation liquid rich in amino acid modified to carbon blacksurface, increases carbon black table under the action of microorganism
The hydrophilic amino group and carboxyl quantity in face, improve the hydrophily of carbon black, while the carboxylic group in amino acid can be
Stable solvated layer is formed in water, while adsorbing the cation in water and forming double electrical layers, and the repulsive force of generation can hinder
Collision cohesion between carbon black pellet, avoids agglomeration, carbon black is made to have splendid water dispersible.
The beneficial effects of the present invention are:
