Abstract
Inventia se refera la un electrolit de cuprare, utilizînd electrolit tip sulfat si aditivi a caror efect sinergetic permite depunerea unor straturi nivelate lucioase (grad de luciu 92...97%), aderente si uniforme ca structura. Electrolitul, conform inventiei, contine 1 mg/l...0,035 g/l dintr-un aditiv cu efect sinergic format la rîndul sau din 0,03...0,04 g/l m ercaptoalehilsul fonat de sodiu, 0,02...0,04 g/l clorhidrat de 1-(3,4 dihidroxi-fenil)-2-izopropil- amino etanol, 0,1...1 mg/l ftalocianina de cupru sulfonamidata, 0,035...0,04 bloc copolimer etoxi- propoxi cu grad de etoxilare 50 si propiloxare 75, 0,002...0,003 g/l tiouree, 2...3 mg/l 2-mercapto- 6-metil-pirimidin-4-ona.The invention relates to a copper electrolyte using sulfate electrolyte and additives whose synergistic effect allows the deposition of glossy layers (92 ... 97% gloss), adherent and uniform in structure. The electrolyte according to the invention contains 1 mg / l ... 0.035 g / l of an additive having synergistic effect in the order of 0.03-0.04 g / l of sodium ercaptoalylsulphonate, 0.02. .0,04 g / l 1- (3,4-dihydroxy-phenyl) -2-isopropylamino ethanol hydrochloride, 0.1 ... 1 mg / l sulfonated copper phthalocyanine, 0.035 ... 0.04 ethoxylated propoxy block copolymer 50 and propyloxane 75, 0.002 ... 0.003 g / l thiourea, 2-3 mg / l 2-mercapto-6-methyl-pyrimidin-4-one.
