Description
Technical field
The present invention relates in fine inorganic chemical field aluminium pigment preparation method, specifically a kind of wet production is non-
The preparation method of leafing aluminum paste.
Background technology
Aluminium pigment is the pigment produced with pure aluminum metal.Aluminium pigment particle is actually Surface coating fatty acid thin film
There is the tablet of pigment characteristics, this form to make it have superior decay resistance and decoration performance, application is widely.
The manufacture method of existing aluminium pigment mainly includes dry production and wet production.Existing wet production includes：(1) by aluminium powder with have
Machine solvent, lubricant etc. are placed in grinding in ball grinder after mixing by a certain percentage；(2) the good material of ball milling filter pressing after screening
Into filter cake；(3) filter cake becomes aluminum paste through mediating surface treatment.When using Oleic acid (carbon octadecenic acid is unsaturated fatty acid)
The aluminum paste produced during as lubricant (surface conditioning agent) is non-leafing aluminum paste；When using stearic acid (carbon octadecanoid acid,
By satisfied fatty acid) as lubricant (surface conditioning agent) when the aluminum paste that produces be leafing aluminum paste.
The ball-grinding machine of existing non-leafing aluminum paste wet production is generally horizontal ball mill, and liner material is potassium steel；
Ball-milling medium is generally carbon steel balls；Other production equipments or facility material are generally carbon steel；Lubricant is generally Oleic acid.Due to carbon
Abrasion of the potassium steel of steel ball and ball mill inwall during grinding, cause the irony of product to pollute and Oleic acid and ferrum
Reaction causes the color for having enough to meet the need solvent naphtha more and more deeper.In turn result in aluminum paste product iron-holder high, the color shade of product is not
Pure, whiteness and luminance-reduction.
Therefore, it is that the color shade of product is pure so that aluminum paste product iron-holder is low, whiteness and brightness are high, this area
Middle need to provide a kind of preparation method of new non-leafing aluminum paste.
Content of the invention
It is an object of the invention to overcoming the shortcomings of the non-leafing aluminum paste of existing wet production, there is provided a kind of iron-holder is low,
Pure color, whiteness are good, the preparation method of the high non-leafing aluminum paste of brightness.
Therefore, the present invention provides a kind of preparation method of non-leafing aluminum paste, including mean diameter is less than 50 microns
Fine spherical aluminum powder is placed in ball milling in the ball mill with zirconia material as liner, the lubricant with organic solvent and lubricant
For isostearic acid, zirconia ball in the ball mill, is adopted to be situated between for mill；After ball milling, screening and solid-liquid separation obtain the non-floating type
Aluminum paste.
The liner can be that pure zirconia material, or cerium stabilizing zirconium oxide material etc. contain zirconic material,
This is unrestricted in the present invention.
In a kind of specific embodiment, by the fine spherical aluminum powder, organic solvent and lubricant elder generation mix homogeneously
Mixture is inserted ball milling in the ball mill again afterwards, and the mean diameter of preferably described fine spherical aluminum powder is less than 10 microns.
In a kind of specific embodiment, a diameter of 0.3～2mm of the zirconia ball, preferably 0.5～1mm；Ball milling
Fine spherical aluminum powder described in step is 1 with the mass ratio of zirconia ball：5～80, preferably 1：10～50.
In a kind of specific embodiment, the zirconia ball is cerium stabilizing zirconium oxide ball.Cerium stabilizing zirconium oxide ball
There is the characteristics of density big (bigger than the density of zirconia ball), surface are moist, abrasion are extremely low and do not contain irony.It is described that " cerium is steady
Determine zirconia ball " can be by commercially available acquisition, it belongs to a kind of ripe commodity.
In a kind of specific embodiment, the mass ratio of the fine spherical aluminum powder, organic solvent and lubricant is
100：50～1000：0.5～20, preferably 100：150～500：2～6, more preferably 100：200～400：3～5.
In a kind of specific embodiment, in methods described except inner liner of bowl mill and mill be situated between in addition to other with prepare aluminum
Stainless steel is partly or entirely adopted at silver paste raw material, intermediate product and product directly contact.
Pipeline, hopper, screening machine, delivery pump and kneading in a kind of specific embodiment, in the preparation method
Stainless steel is adopted at the directly contact in machine.
In a kind of specific embodiment, time of material ball milling in ball mill is 10～200 hours, preferably 20～
60 hours, more preferably 30～40 hours.
Heretofore described organic solvent is organic solvent commonly used in the art, specifically could be for ball milling and prepares aluminum
The single organic solvent of silver paste or mixed organic solvents, the organic solvent are, for example, D70.
In a kind of specific embodiment, the screening crosses 200～500 mesh sieves for the mixed material after ball milling, sieves
Material enter pressure filter in solid-liquid separation, filtrate return to ball milling and screening operation recycle, filter cake enter kneading process after
Become non-leafing aluminum paste product.In a kind of specific embodiment, 500 mesh sieve used in screening step.
In the present invention first by isostearic acid be lubricant, isostearic acid be stearic isomer, be saturated fat
Acid, the aluminum paste produced during with which as lubricant (surface conditioning agent) are but non-leafing aluminum paste.Combining in the present invention makes
With isostearic acid be lubricant, zirconium oxide is liner and the use of zirconia ball is that mill is situated between used in ball mill, obtain a kind of brand-new
Non- leafing aluminum paste preparation method, the color and luster and iron content of the non-leafing aluminum paste of gained are greatly improved.Especially tie
When closing the part using stainless steel, products obtained therefrom iron content is low, pure color, and turnover solvent naphtha is colourless, will not cause
The harmful effect to product quality is increased with the prolongation of solvent naphtha use time.
In sum, beneficial effects of the present invention are：The present invention is due to using liner zirconia ball mill and cerium Stable Oxygen
Change the equipment or facility of zirconium ball and stainless steel and using isostearic acid as lubricant, it is to avoid in production process particularly
Impact of the ferrum to product quality in mechanical milling process.It also avoid Oleic acid used in traditional non-leafing aluminum paste production process etc.
Lubricant is reacted with ferrum and causes to have enough to meet the need the deeper and deeper phenomenon of color of prime city naphtha.Produced using preparation method of the present invention
Product iron-holder is low, pure color, and whiteness is good, and brightness is high.
