Description
Technical field
The present invention relates to fluorescent pigment preparing technical field, specially a kind of superfine grinding method of fluorescent pigment.
Background technology
Chemical products breaking method mostly uses gas flow crushing process, and principle of air-blast pulverizing uses airslide disintegrating mill and whirlwind
Separator, deduster, air-introduced machine constitute a whole set of crushing system.Compressed air is high by Laval nozzle after filtration drying
Speed spurts into crushing chamber, at the joint of multiply high pressure draught material by impact several times, friction, shearing and crush, after crushing
Material with ascending air move to graded region under blower fan draft effect, the stage turbine of high speed rotation produce it is powerful from
Under mental power function, make thickness feed separation, the fine grained for meeting granularity requirements enters cyclone separator and dedusting by grading wheel
Device is collected, and coarse granule, which drops to disintegrating area, to be continued to crush.
At present because fluorescent pigment resin fragility is undesirable and hardness is higher, gas flow crushing process crushing can only achieve flat
Equal 5-6 microns of particle diameter and particle diameter distribution is uneven.As fluorescent pigment is in the extensive use of ink, water paint, the field pair
Particle diameter proposes high requirement, it is desirable to which average grain diameter reaches less than 2 microns, therefore, and improvement fluorescent pigment breaking method has been compeled in eyebrow
Eyelash.
The content of the invention
Technical problem solved by the invention is to provide a kind of superfine grinding method of fluorescent pigment, to solve the above-mentioned back of the body
The problem of in scape technology.
Technical problem solved by the invention is realized using following technical scheme：A kind of ultra-fine grinding side of fluorescent pigment
Method, comprises the following steps：
A, the fluorescent pigment coarse fodder of the 50-100 mesh of 250-350 mass parts delivered in enamel reaction still；
B and then the water of 700-1000 mass parts is injected into enamel reaction still；Ensure coarse fodder be deposited to bottom continue into
Row is crushed；
C, the dispersant of 0.5-2 mass parts is added in enamel reaction still；
D, the zirconium pearl of 250-350 mass parts is added in enamel reaction still；By the rolling friction of the good zirconium pearl of wearability,
The larger larger granules of pigments of bottom particle diameter that sinks to of proportion is subjected to rolling friction crushing, bulky grain is ground into small to reach
Grain.
E, startup stirring motor are stirred, and mixing speed is 200-300 revs/min of motor speed, and time consuming 24-48 is small
When, 15-40 degrees Celsius of slurry temperature；
F, using Filter Press after, after being dried by flash drying equipment, final fluorescence is determined by laser particle analyzer
Pigment grind granularity is 1-2 microns.
The dispersant is anion sulfoacid salt dispersant.
The zirconium pearl is zirconium silicate pearl.
Compared with disclosed technology, there is advantages below in the present invention：Powder particle diameter of the present invention is more carefully, evenly；Using water as
Medium is crushed, therefore dust from flying is not resulted in crushing process, influences environment；Crushing process is not with pressure, stirring at low speed is without making an uproar
Sound, reduces the generation of production process security incident.
