Abstract
The invention discloses a super mercerization argentalium silver paste preparation method. A double-supersystem speed reduction technique is adopted, spherical aluminium powder is quickly extended in an initial stage of ball milling, and a low-speed polishing effect is achieved in a later stage. Damage to aluminium powder surfaces caused by ball milling media is reduced, finish of the aluminium powder surfaces is improved, and accordingly aluminium paste surfaces are soft, fine and glossy like silk, ball milling time is reduced, energy consumption is reduced, product quality is improved, and great economical efficiency is brought in.
Description
Technical field
The present invention relates to non-floating type aluminium-silver slurry method field of manufacturing, be specifically related to a kind of method of manufacture of super mercerising silver aluminium-silver slurry.
Background technology
Aluminium-silver slurry is a kind of silvery white metallic pigment with metalluster, is used in automobile in a large number, household electrical appliances, the topcoating field of electronic product etc.General non-floating type aluminium-silver slurry; Be that according to the rules time and rotating speed adds the disposable ball milling success of ball mill with sphere or subsphaeroidal atomizing aluminium powder and steel ball and lubricant, ball-milling additive etc.; Need bigger rotating speed to guarantee that aluminium powder can rapid deployment at the ball milling initial stage, but, after aluminium flake launches, can not well polish on the too fast easy damage aluminium flake of ball milling later stage rotating speed surface; Cause the particle diameter of aluminium flake inhomogeneous, brightness and whiteness are relatively poor.And the long-time big rotating speed energy consumption of ball mill is big, and cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of method of manufacture of super mercerising silver aluminium-silver slurry, reduce ball mill ball milling later stage in stage speed, the aluminium flake after the expansion can better be polished and protect.
Technical scheme of the present invention is following:
A kind of method of manufacture of super mercerising silver aluminium-silver slurry is characterized in that: specifically may further comprise the steps:
(1), choose diameter be 0.4 ~ 0.6mm high-carbon steel ball as ball-milling medium, be that the nitrogen atomization ball aluminum powder of 1 ~ 4 μ m drops into ball mill together with diameter, in ball mill, add the grinding aid ball milling then;
(3), when ball mill reaches 20 ~ 24 hours with rotating speed ball milling time of 45 rev/mins; With the speed drop to 28 of ball mill rev/min; Ball mill continues polishing and obtains slurry after 10-12 hour; Sent into setting tank deposition after the screening of slurry through 600 mesh sieves 5 ~ 7 hours, and sent in the whizzer centrifugal 2 ~ 4 hours to slurry then, form aluminium flake when reaching 90% left and right sides when consolidating of al particulate in the slurry contains; Send into aluminium flake in the kneader then and mediate, and in kneader, add solvent and inhibitor carries out surface treatment to aluminium flake;
(3), pack after mediate accomplishing, promptly obtain super mercerising silver aluminium-silver slurry.
The method of manufacture of described super mercerising silver aluminium-silver slurry, it is characterized in that: ball mill adopts horizontal ball mill, the high-carbon steel ball that it is 0.5mm that ball-milling medium is chosen 1.5 tons of diameters.
The method of manufacture of described super mercerising silver aluminium-silver slurry, it is characterized in that: grinding aid is selected 150# solvent oil, erucic acid for use.
The method of manufacture of described super mercerising silver aluminium-silver slurry, it is characterized in that: solvent is selected the S150# solvent oil for use.
The method of manufacture of described super mercerising silver aluminium-silver slurry, it is characterized in that: the polishing time of ball mill accounts for 1/3rd of its total ball milling time.
Beneficial effect of the present invention:
The present invention has reduced the later stage speed in ball mill ball milling stage, and the aluminium flake after the expansion can better be polished and protect, and makes surface-brightening, the exquisiteness, soft of aluminium-silver slurry, has the texture of silk, and the effect that cuts down the consumption of energy with equipment loss is arranged.
