Abstract
The invention relates to a method for sheeting the ball metal aluminum powder in water solution, wherein it fills the ball metal aluminum powder formed by atomization and smaller than 75 mum (200deals), into the grinder while the grinding medium is 1/20-1/40 weight; adding pure water at 2-4times weight of aluminum powder, adding lubricant, surface activator, emulsifier, grinding for 3-20h, taking out aluminum powder, filtering, obtaining the sheet aluminum powder at scale structure and better disperse property in water. The invention uses pure water to replace traditional solvent oil. And the invention can reduce cost.
Description
Technical field
Invention relates to a kind of method for laminating round metallic aluminium, and particularly the method for sheet ball aluminum powder in aqueous medium belongs to the fine inorganic chemical field.
Background technology
The sheet process of ball aluminum powder is the key of preparation aluminum metal pigment.Because the pigment aluminium powder requires particle to have flakey, this lepidiod particle state just makes aluminium powder pigment have metallic luster and shielding action.In the production of aluminium powder pigment, with the aluminium ingot raw material mostly, by the molten atomizing method, make ball aluminum powder; Utilize physical refining processes such as ball milling again, ball aluminum powder is converted into the flakey aluminium powder.
About the sheet method of ball aluminum powder, mainly contain two kinds:
First method is the dry type ball-milling method, adds oleic acid, stearic acid as lubricant in spherical aluminium powder, adopts the dry type ball milling, and spherical aluminium powder is converted into flake aluminum.
Second method is the wet ball-milling method, this method and dry type ball-milling method difference are that spherical aluminium powder is in mechanical milling process, except that adding lubricant, also will add mineral oil, 200# solvent wet goods organic solvent, and the addition of organic solvent is much larger than the addition of lubricant and auxiliary agent.
Because aluminium powder is inflammable and explosive, there is the danger of blast in dry type ball milling processing method, often needs nitrogen protection, and it is not really general that industrialization is at present adopted.The wet ball grinding processing method is generally adopted in industrialization, and the main effect of its lubricant is to prevent ball aluminum powder in mechanical milling process and since the mechanism of medium such as steel ball the cold welding that may occur connect phenomenon; Other auxiliary agents have stabilizing agent, dispersant, surface-protective agent and antiprecipitant etc., its objective is surface metal gloss that improves flake aluminum and the requirement of satisfying follow-up coating industry; The effect of solvent mainly is an efficient of wanting to improve sheet chemical industry journey, can drop to the explosion danger that aluminium powder exists minimum again simultaneously.
The aluminium powder pigment that not only makes cost increase, produce that uses of organic solvent is the oiliness aluminium powder pigment, is difficult to disperse in aqueous medium, is difficult to satisfy the requirement of water paint.And the main difficulty that the production of water-based flake aluminum exists is because water can produce hydrogen with the aluminium powder reaction, and its evolving hydrogen reaction formula is as follows:
The evolving hydrogen reaction of above-mentioned aluminium powder also can cause production process dangerous, because hydrogen also has the danger of blast; Evolving hydrogen reaction will cause that also aluminium powder surface metal gloss reduces, directly has influence on the serviceability of flake aluminum product in addition.
Summary of the invention
In order to satisfy the needs of environmental protection and aqueous product, the invention provides the sheet method of spherical aluminium powder in a kind of aqueous solution, this method substitutes organic solvent with pure water, has solved environmental issue, and the flake aluminum product of its production has good dispersiveness in water.
The sheet method of spherical metal aluminium powder in a kind of aqueous solution, the spherical metal aluminium powder that the spray-on process less than 75 μ m (200 order) of the abrasive media weight 1/20～1/40 of packing in milling apparatus is made, the pure water that adds 2～4 times of aluminium powder weight again, with aluminium powder and pure water weight is benchmark, the lubricant that adds weight 1～10%, 1～3% amphoteric surfactant, 1～5% emulsifying agent, under 70～100% rotating speed of ball milling critical speed, ground 3～20 hours, after milling time is finished, take out the aluminium powder in the ball mill, have sclay texture through filtering, being, metallic luster is strong, the flake aluminum that in water, has good dispersion.
Described milling apparatus comprises that with steel ball as wet lapping equipment such as the ball mill of abrasive media, agitator mill, vibrating mills, ball-milling medium is a steel ball, and the steel ball charge weight is 45%, and steel ball size is 1-5mm.
The first water of described pure water for making by heating evaporation, or the pure water that makes by methods such as ion-exchange, reverse osmosis membrane separation.
Described lubricant for effectively being adsorbed in the higher fatty acids on aluminium powder surface, comprises oleic acid, erucic acid, and its effect mainly is that aluminium powder and water are separated, and avoids " cold welding " phenomenon that may occur in grinding deformation process between the aluminium powder simultaneously.
Described amphoteric surfactant has enough solubility in water, guarantee that aluminium powder fully disperses, and any reunion can not take place.Mainly comprise the betaine type amphoteric surfac-tant.
Described emulsifying agent can make the lubricant can fine emulsification in water, improves the dispersiveness of lubricant in water, guarantees that lubricant can mainly comprise peregal class emulsifying agent in the effectively absorption of aluminium powder surface.
The present invention adopts pure water to replace traditional solvent naphtha, and its product can fully disperse in water, for the production of water aluminum-silver slurry product lays the foundation.The sheet process not only reduces production costs, and has environment protection significance owing to adopt the aqueous solution, and its follow-up water aluminum-silver slurry can be widely used in water-based metal printing ink and coating.
Description of drawings

The specific embodiment
Embodiment: Φ 200 * 200mm ball mill, Φ 2mm steel ball 40Kg packs into, the spraying ball aluminum powder 1.5Kg that adds 12 microns of average diameters adds distilled water 5Kg, adds aliphatic acid and beet alkali surface activator (1: 1) 300g, peregal emulsifying agent agent 100g, ball milling is 15 hours under 100rpm, adds distilled water then product is washed out, and carries out Separation of Solid and Liquid by filtration again, can obtain the aluminium powder product of filter cake shape, its laminated structure as shown in Figure 1.
Detect through SEM, the average thickness of flake aluminum of the present invention (t) is 0.2～0.7 μ m, averaged particles footpath (D
50) be 5～20 μ m, radius-thickness ratio (t/D
50) be between 15～50.
The filter cake shape flake aluminum product that obtains can fully disperse in aqueous solvent, alcohols solvent.With the filter cake that obtains, with commercially available diluent and gloss oil (resin), according to being made into metallic paint at 1: 2: 8, the metallic paint that is disposed, have good silvery white metallic luster and ornamental, planarization effect, its general effect can compare favourably with the effect of the prepared product of traditional 200# solvent wet goods organic solvent.
