Description
Technical field
The present invention relates to a kind of preparation method of water-based metal pigment, especially relate to a kind of preparation method of water aluminum-silver slurry.
Background technology
Aluminium powder pigment has excellent glossiness and tone, is one of important metallic pigment.Along with development of science and technology, the kind of aluminium powder pigment is more and more, now has been widely used in the multiple industry and the commercial fields such as internal and external ornament of automobile, motorcycle, sports equipment, electric equipment products, buildings.
Along with the pay attention to day by day of people to environment protection, the aluminium powder that can be applied to water-based system is that water aluminum-silver slurry has also obtained a large amount of research.Water aluminum-silver slurry has unique environmental friendliness function, can be widely used in water-borne coatings and water color ink.Water aluminum-silver slurry can not only make film forming matter have advantages such as acidproof, alkaline-resisting, high temperature resistant, and can compare favourably with the oiliness aluminium-silver slurry at aspects such as metalluster, opacifying powers.
But, because aluminium is easy to and water reacts, when being applied to water-based system, this reaction not only can destroy the metalluster of aluminium powder, and consequent hydrogen (promptly " getting angry "), cause burning or blast easily, therefore to produce the reaction that water aluminum-silver slurry at first will stop aluminium powder and water.What adopt at present is two kinds of technology based on different principle: the one, and additive technology, promptly on the aluminium powder pigment particle surface with the physical method mixed additive, form a protective layer by modes such as electrostatic adhesion at the aluminium flake skin, protective layer plays iris action, stop the reaction of aluminium and water, but the protective layer instability that forms, disassociation easily in medium; The 2nd, coating technology, one aluminium powder particle is wrapped, thereby stops the reaction of aluminium and water, and this coating is stable, can form powerful combinations such as hydrogen bond, is not easy to break away from medium.
Coating technology normally contains chromium cpd or silicon dioxide film at aluminium powder surface coverage one deck.Chromium ion pollutes the environment, and its application is restricted.Silicon dioxide film has excellent inertia and wetting ability, lower film-forming temperature, and the transparency of its uniqueness can not damaged the luster performance of aluminium powder, thereby is more studied.Present research concentrates on adopts sol-gel method to form silicon dioxide film, promptly utilizes organosilyl hydrolysis-condensation to coat the uniform SiO of last layer on the surface of flake aluminum
2Film.
But in the prior art, because the speed of sol-gel is difficult to homogeneous, and the irregularity of aluminium powder micro-shape, the silicon dioxide film that makes sol-gel method form exists and coats imperfect, problem such as come off easily, thereby can not stop the generation of hydrogen fully.
Simultaneously, there is a large amount of hydroxyls in the silicon dioxide film surface, and hydroxyl makes coating aluminium powder surface present wetting ability, the formation tridimensional network but this surface absorbs water again easily.The intermolecular reactive force of this tridimensional network is very strong, make and attract each other, tangle between the aluminium powder particle, thereby the aluminium powder particulate of coated with silica is agglomerated into aggregate easily, is unfavorable for the dispersion in application system, is unfavorable for embodying the advantage of water aluminum-silver slurry.
In addition, traditional oiliness aluminium powder has grinding aid in surface bonding in kneading process, as oil soluble long-chain materials such as stearic acid, oleic acid, grinding aid can not only effectively alleviate the deadweight of aluminium powder, and it is floating in medium to be convenient to aluminium powder, and can improve the consistency of aluminium powder and resin.But for making the water-based aluminium powder possess the good hydrophilicity energy, can not be at oil-soluble substances such as aluminium powder surface bonding stearic acid, oleic acid, this makes the consistency and the showy degradation of aluminium powder in medium of water-based aluminium powder and resin.The coated with silica aluminium powder also can reduce surface tension in addition, thereby makes consistency descend more, can cause the problem of after the film forming drying " dry linting ".The showy degradation of water-based aluminium powder can make aluminium powder precipitate gathering in water-based system, is unfavorable for using.
For example, provided a kind of preparation method of silicon dioxide coating type water aluminum-silver slurry in disclosed Chinese patent application announcement on August 6th, 2008 CN101235226A, this preparation method coats aluminium powder by silicon dioxide film, obtain in the aqueous solution, to have good dispersion, and water aluminum-silver slurry with excellent acid-fast alkali-proof performance, but this method belongs to individual layer to coat, and exists coating layer to come off, coat defectives such as imperfect and dry linting easily, can't stop the generation of hydrogen fully.
For example, the Chinese patent CN100465235C of Granted publication provided a kind of preparation method of coated aluminium powder pigment on March 4th, 2009, this method is utilized organo-siloxane to form the first layer on the aluminium powder pigment surface and is coated, utilize reacting generating copolymer that aluminium powder is carried out coating the second time, preferably resolve traditional aluminium powder " getting angry " problem in use and storage process, kept good metal gloss simultaneously, but this method is to carry out polyreaction in the coating system, can destroy original silicon dioxide film that forms, and the polymer coated silica film that reaction obtains, when realizing complete coating, also destroyed the wetting ability of silicon dioxide film, add that polymkeric substance self lacks hydrophilic segment, thereby this system wetting ability deficiency, will cause coating the difficulties in dispersion of aluminium powder in water-based system.
This shows, prior art solutions all can not coat complete, coating layer does not come off, solved in no dry linting, dispersiveness and the reunion comprehensively.
