Description
Technical field
The invention belongs to chemical production technical fields, are related to a kind of preparation method of white carbon black, concretely relate to one
Kind is used for the preparation method of rubber reinforcing filler white carbon black.
Background technique
The rubber size of white carbon black reinforcement increasingly attracts people's attention, and the dosage of white carbon black is almost all increasing every year
Long, the reason of growth, includes：Better fuel oil is obtained because reducing rolling resistance to save, and extends the service life of tyre surface.But
Because there is highly polar hydroxyls for the surface of white carbon black, keep white carbon black incompatible with rubber.Since white carbon black has the trend of aggregation,
Mechanical means can not force white carbon black to disperse well in rubber, and then the physical property of vulcanizate can not reach best
State.
Although the main component of white carbon black is silica, but commodity production white carbon black is not spherical shape or spherical mostly,
But the irregular shape of similar grape string structure, and be the aggregate of silica, aggregation size is much larger than 50 nanometers, very
Hardly possible is used for emulsion polymerization, that is, is used in emulsion polymerization, can not also stablize preservation.China Patent Publication No. CN1369511A is disclosed
A kind of preparation of " the nucleocapsid structure hybrid that organic polymer and inorganic nano material are constituted ", which applies produces one kind
The aqueous emulsion of core-shell structure, the aqueous emulsion are used for the binder of adhesive and coating, fine for papermaking, carpet, non-woven fabrics, fabric
Dimension processing, printing and dyeing and building decoration etc., only for the purpose of producing core-shell structure particle, involvement rubber effect is poor, mixes
The refining time is long, and reinforcing effect is not significant enough.
Summary of the invention
The present invention in view of the above-mentioned deficiencies, proposes a kind of preparation method for rubber reinforcing filler white carbon black, the present invention with
Commodity white carbon black is raw material, is modified to commodity white carbon black, can reduce mixing time, improve mixing behavior, benefit also can be improved
Potent fruit.
The technical scheme is that：A kind of preparation method for rubber reinforcing filler white carbon black, it is characterised in that：In quotient
Modifying agent is added in product white carbon black to be made, the modifying agent by the sodium hydroxides 0.01~0.2 of parts by weight, sodium salicylate 0.01~
0.3, deionized water 5~10 is made, and the modifying agent is added to stirring 30min in reaction kettle, water and milk mixture is made；It will weigh
Measure the Heveatex 10~50, divinyl pyridine 10~60, Heveatex 5~40, deionized water 100~500, ammonium hydroxide 2 of part
~15 are made deionized water, are ground into white carbon black suspension after deionized water is added in the commodity white carbon black, then water and milk is mixed
After closing object addition white carbon black suspension stirring, by obtaining rubber reinforcing filler white carbon black after drying and crushing.
The solid content of the water and milk mixture is 10~50%.
The white carbon black suspension is to be added to parts by weight in deionized water for 10~100 commodity white carbon black raw materials to make
The suspension for being 20%~60% at mass fraction.
The drying is one of microwave drying and far-infrared ray drying, and dry temperature is 100~150 DEG C, dry
Time is 3~4 hours.
The content of the divinyl pyridine is 10~30%.
Beneficial effects of the present invention are：A kind of preparation method for rubber reinforcing filler white carbon black provided by the invention, with
Traditional commodity white carbon black is compared, and solving traditional white carbon black cannot disperse well in rubber, the physical property of vulcanizate
Optimum state can not be reached, mixing time is reduced, improve mixing behavior, improve the reinforcing effect of white carbon black, reduced
Rolling resistance and obtain better fuel oil and save, extend the service life of tyre surface.
Specific embodiment
A kind of preparation method for rubber reinforcing filler white carbon black is added modifying agent in commodity white carbon black and is made, modified
Agent is made of the sodium hydroxide 0.01~0.2, sodium salicylate 0.01~0.3, deionized water 5~10 of parts by weight, by modifying agent plus
Enter into reaction kettle stirring 30min and water and milk mixture is made；By the Heveatex 10~50 of parts by weight, divinyl pyridine 10~
60, deionized water is made in Heveatex 5~40, deionized water 100~500, ammonium hydroxide 2~15, is added and is detached from commodity white carbon black
White carbon black suspension is ground into after sub- water, then after the stirring of white carbon black suspension is added in water and milk mixture, after drying and crushing
