Description

Znane jest powlekanie metali lub drze¬ wa lakierami z estrów lub eterów celulozy, a mianowicie przez pociaganie, zanurzanie, szczotkowanie lub skrapianie powierzchni roztworami laków.Wedlug wynalazku otrzymuje sie od¬ porne powloki na metalach lub drzewie przez nalozenie lakierów z estrów lub ete¬ rów celulozy zapomoca zwyklych maszyn do wytwarzania oleodruków, a wiec przez przeniesienie roztworu laku z walców me¬ talowych poprzez gumowe i zelatynowe znów na walce metalowe lub przez nadru¬ kowanie zapomoca maszyn wkleslodruko¬ wych lub innych maszyn drukarskich. W ten sposób uzyskuje sie wszelkie odcienie barw i efekty wielobarwne. Otrzymane druki sa bardzo odporne na dzialanie lu¬ gów, np, roztworów mydla, jak równiez na zwykle organiczne srodki czyszczace, jak benzyna, benzol, olej terpentynowy i t. d.t przez co róznia sie one zasadniczo od po¬ wlok, wytwarzanych zapomoca druków o- lejnych, których odpornosc na mocne roz¬ twory mydla i na wyzej wymienione orga¬ niczne srodki czyszczace jest stosunkowo mala. Przy drukach olejnych pomiedzy nakladaniem poszczególnych barw nie¬ zbedne sa procesy suszenia, najczesciej w piecach przy 160°, co w przypadku niniej¬ szym jest zbyteczne.Powloki z lakieru bezbarwnego sklada¬ ja sie z 220 czesci suchej nitrocelulozy, 120 czesci 95'o-wego alkoholu, 130 czesci estru dwubutylowego kwasu ftalowego i 530 cze¬ sci glikolo-jednoetylowegb oraz 150 czescibronzu aluminjowego. W ten sposób wy¬ tworzony lakier drukuje sie zapomoca zwy¬ klej maszyny do wytwarzania oleodruków na blasze bielonej.Zamiast bronzu alumlnjo do lakieru dodac takze farby ziemne orga¬ nicznych baiiwników przez zmieszanie lub mechaniczna przeróbke np. w mlynku lej¬ kowym, trójwalcu i t. d. Mozna taikze do¬ dac do lakierów zywice, pokosty, oleje i t. d. lub tez lepidlo barwników, zawiera¬ jace te skladniki.Bezbarwny lakier skladac sie moze równiez z 10 czesci acetylocelulozy, 5 cze¬ sci estru dwumetylowego kwasu ftalowego i 70 czesci octanu eteru glykolo-jednomety- lowego oraz 25 czesci octanu eteru glykolo- jednometylowego, 25 czesci 20% ciasta z zólcieni,,Hansa 5 G" i 20 czesci octanu ete¬ ru glikolo- j ednometylowego. Otrzymany lakier mozna nadrukowac zapomoca zwy¬ klej maszyny wkleslodrukowej na metal lub drzewo. PL PLIt is known to coat metals or wood with cellulose ester or ethers varnishes, specifically by drawing, dipping, brushing, or sprinkling the surface with lacquer solutions. According to the invention, resistant coatings are obtained on metals or wood by applying cellulose ester or ethers varnishes using conventional oleograph machines, i.e., by transferring the lacquer solution from metal rollers through rubber and gelatin rollers back to metal rollers, or by printing using gravure or other printing machines. In this way, all shades of color and multicolor effects can be achieved. The resulting prints are very resistant to the action of alkalis, e.g. soap solutions, as well as to common organic cleaning agents, such as petrol, benzene, turpentine oil, etc., which is why they differ fundamentally from coatings produced by means of oil prints, whose resistance to strong soap solutions and to the above-mentioned organic cleaning agents is relatively low. In oil prints, drying processes are necessary between the application of individual colours, most often in ovens at 160°, which is unnecessary in this case. The clear varnish coats consist of 220 parts of dry nitrocellulose, 120 parts of 95-hydroxyethyl alcohol, 130 parts of phthalic acid dibutyl ester, 530 parts of monoethyl glycol and 150 parts of aluminium bronze. The varnish thus produced is printed using a standard oleograph machine on bleached sheet metal. Instead of aluminum bronze, earthen organic dyes can also be added to the varnish by mixing or mechanical processing, for example in a funnel mill, three-roller, etc. Resins, varnishes, oils, etc., or a dye binder containing these ingredients can also be added to the varnish. A colorless varnish can also consist of 10 parts of cellulose acetate, 5 parts of phthalic acid dimethyl ester, 70 parts of glycol monomethyl ether acetate, and 25 parts of glycol monomethyl ether acetate, 25 parts of 20% paste. from "Hansa 5 G" yellow and 20 parts of glycol monomethyl ether acetate. The resulting varnish can be printed on metal or wood using a standard gravure printing machine. PL PL
