Definitions
- formulations according to the invention are adhesive Effect metallization.
- Preferred spray activator formulations contain 0.05 to 1.5 parts by weight of component a) and 10 to 20 parts by weight of component b).
- Organometallic activators come in the formulations according to the invention Compounds of subgroups 1 and 8 of the periodic table (especially Pd, Pt, Au, Ag). Organometallic ones are particularly suitable Complex compounds of palladium with olefins (dienes), with ⁇ , ⁇ -unsaturated Carbonyl compounds, with crown ethers and with nitriles. Particularly suitable are bisacetonitrile palladium dichloride, butadiene palladium dichloride, 4-cyclohexene-1,2-dicarboxylic acid anhydride palladium dichloride, Mesityl oxide palladium dichloride, 3-hepten-2-one-palladium chloride and 5-methyl-3-hexan-2-one palladium chloride.
- mixtures of these compounds can also be used be used.
- the activators or mixtures thereof are according to the process according to the invention in the aqueous dispersion brought in. This is generally done through Mixing the ingredients. Incorporation of the formulation components can also be done in separate steps be performed. For example, you can use the activator first in a solvent of the total formulation, e.g. pre-dissolve or disperse in ethanol and then filler, e.g. Add Aerosil®.
- the activator is reduced to the metallic form by adding formalin or complexed by means of complexing agents and introduced into the aqueous dispersion of the binder. This is done by stirring or dispersing. Chlorides, thiosulfates, rhodanides, cyanides, ammonia or amines are used as complexing agents.
- Examples of complex compounds are Pd (NH 3 ) 2 Cl 2 , Pd (NH 3 ) 4 Cl 2 , Pd (NH 3 ) 4 (NO 3 ) 2 , K 2 PdCl 4 , K 2 Pd (CN) 4 , [NH 4 ] 2 PdCl 6 , [NH 4 ] 2 PdCl 4 , PL (NH 3 ) 4 Cl 2 , K 2 PtCl 4 , KAg (CN) 2 , KAg (S 2 O 3 ), KAu (CN) 2 , NaAuCl 4 .
- colloidal precious metal systems also as Pd, Ag, Au, Pt can serve as activators Activated carbon, on aluminum oxide, on calcium carbonate Barium carbonate, on activated alumina and Palladium black, called platinum black.
- the fillers come from printing and painting technology known auxiliaries such as pigments, disperse Silicas, carbon blacks, silicates, oxides, rheological Additives and clay minerals are considered.
- Silicates, bentonites and talc are preferred and chalk.
- the amount of filler can range from 0.5 to 3 parts by weight, based on the mass of the formulation, vary.
- Activators and fillers In addition to the dispersible polymers, Activators and fillers other ingredients, such as Surfactants, leveling agents, defoamers, dyes and Metal dyes in low concentrations up to 10 % By weight, preferably up to 2% by weight, is admixed become.
- a solvent in the formulations according to the invention come well-known in printing or painting technology
- ketones for example Methyl ethyl ketone, cyclohexanone
- esters for example Butyl acetate, dioctyl phthalate, butyl glycolate, Glycol ethers, for example ethylene glycol monomethyl ether, Diglyme, propylene glycol monomethyl ether acetate
- Alcohols such as ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol
- Diacetone alcohol Diacetone alcohol. Mixtures of these solvents can of course also be used and their blends with other solvents be used.
- the solvents used only serve to dissolve the organic Pd compound and can optionally after reduction of the precious metal activator by Evaporation can be removed.
- the binders of the aqueous dispersion according to the invention with a polymer content of 10-60, preferably 20-55, particularly preferably 30-50% by weight are known from polyurethane chemistry. They are produced, for example, by reacting polyesters and / or polyethers with aromatic or aliphatic polyisocyanates (Angew. Chemie 82 (1970), 53-63; DE-OS 23 14 512; DE-OS 23 14 513; DE-OS 26 51 506 ).
- polyurethanes which contain no free isocyanate groups, optionally blocked isocyanate groups and / or anionic groups, for example SO 3 groups.
- Linear, aliphatic have been found to be particularly suitable Proven polyurethanes, such as those made from hexanediol, Neopentyl glycol and polyisocyanates become.
- fillers, binders and solvents contain the formulations optionally surfactants, leveling agents and / or dyes.
- Suitable as substrates for the process according to the invention paper, enamel, ceramic, polyethylene, polypropylene, Epoxy resins, polyesters, polycarbonates, polyamides, Polyimides, polyhydantoins, ABS plastics, silicones, Polyvinyl halides and polyvinylidene fluoride in the form of Foils, plates, papers and nonwovens.
- substrates like those used in the electronics industry can be used as a housing, e.g. ABS and polycarbonate plastics or their blends, polyphenylene sulfide, Polybutylene terephthalate and its blends and polypropylene oxide.
- the solvents are removed. This happens through Drying or tempering at substrate-specific temperatures, for example between room temperature and 240 ° C under normal pressure, increased pressure or vacuum.
- the Drying time can be varied.
- the surfaces treated in this way then only have to in the case of the complexed activator by reduction be activated, e.g. through reducing agents such as Formaldehyde, hypophosphites, rongalite and boranes.
- reducing agents such as Formaldehyde, hypophosphites, rongalite and boranes.
- One form of the process is therefore that the Reduction, e.g. in the case of complex activators, in the metallization bath with the reducing agent the electroless metallization is carried out.
- a preferred form of the method exists in the fact that formulations are used in which the activator already in active form by reduction is present.
- the formulations according to the invention are particularly suitable for the partial activation geometrically more complicated Surfaces, especially for the production of or moldings metallized on both sides or by Metallized housing parts on the inside for the electronics industry for the purpose of electromagnetic Shielding. By using this procedure, of course also structured metal surfaces using a suitable mask.
