Description
Wynalazek dotyczy wytwarzania mas piszacych z wlasciwego materialu piszace¬ go, materialów obciazajacych i spoiw.Wynalazek ma za zadanie wytworze¬ nie niewrazliwych na wilgoc mas pisza¬ cych, np. rdzeni do olówków.Cel powyzszy osiaga sie wedlug wyna¬ lazku w ten sposób, ze przy sporzadzaniu rdzenia stosuje sie spoiwa poczatkowo rozpuszczalne w wodzie, które jednak przez obróbke cieplna doprowadza sie do stanu nierozpuszczalnego bez szkody dla ich wlasciwosci spajajacych.Jako spoiwa stosuje sie rozpuszczalne w wodzie zywice sztuczne, np. produkty kondensacji fenolu i aldehydu mrów¬ kowego albo mocznika i aldehydu mrów¬ kowego. Te zywice sztuczne czyni sie przez obróbke cieplna nierozpuszczal¬ nymi.Jako spoiwo w mysl wynalazku mozna uzyc takze roztworów dwóch lub wiekr szdj liczby zywic sztucznych, które pod dzialaniem ciepla lacza sie w nierozpusz¬ czalne zywice sztuczne.Poza tym jako spoiwa mozna uzyc roz¬ puszczalnych w wodzie produktów kon¬ densacji fenolu i aldehydu mrówkowego wzglednie mocznika i aldehydu mrówko¬ wego i po dodaniu srodków utwardzaja¬ cych uczynic je na drodze cieplnej nie¬ rozpuszczalnymi.Mozna wreszcie oprócz spoiw, sklada¬ jacych sie z zywic sztucznych, stosowac jeszcze inne rozpuszczalne w wodzie spoi¬ wa, jak np. tragant.Przy wykonywaniu wynalazku uzywa sie np. nastepujacych mieszanin: Przyklad I. 28 czesci blekitu metyleno¬ wego, 45 ,, grafitu, 24 ,, rozpuszczalnego w wodzie produktu kondensacji fenolu i aldehydu mrów¬ kowego (rezolu), 3 ,, srodka zmiekczaja¬ cego. 100 Przyklad IL 28 czesci eozyny, 35 ,, kaolinu, 10 „ stearynianu wap¬ niowego, 22 „ rozpuszczalnego w wodzie produktu kondensacji mocz¬ nika i aldehydu mrówkowego (np. kaurytu) w prosz¬ ku lub roztworze, 5 „ tragantu. 100 Przyklad IIL 28 czesci blekitu metyleno¬ wego, 20 „ kaolinu, 15 „ lojku, 10 „ stearynianu wap¬ niowego, 22 „ dwumetylomoczni- ka i srodka utwar¬ dzajacego (estru kwasu mrówkowe¬ go), 5 „ tragantu. 100 Z mieszanin wedlug przykladu I, II, lub III wytwarza sie dodajac wody ciasto- wata mase plastyczna, z której przez po¬ wszechnie stosowane prasowanie wytwa¬ rza sie rdzenie, Gotowe rdzenie sa do tego stopnia niewrazliwe na wilgoc, ze nawet gotowane w wodzie nie miekna.Wedlug wynalazku mozna wytwarzac rdzenie do pisania, rysowania, kopiowa¬ nia i rdzenie kolorowe wszelkiego rodza¬ ju, a takze przybory do pisania ksztaltu sztabek, jak np. kredki do rysowania i ro¬ bienia znaków. PLThe invention relates to the production of writing materials from a suitable writing material, weighting materials and binders. The object of the invention is to produce moisture-insensitive writing materials, e.g. pencil cores. According to the invention, the aim is achieved by that in the preparation of the core, initially water-soluble binders are used, which, however, are made insoluble by heat treatment without detriment to their bonding properties. Water-soluble synthetic resins, e.g. condensation products of phenol and formaldehyde, or urea and formaldehyde. These artificial resins are rendered insoluble by heat treatment. As a binder in the context of the invention, solutions of two or more than one number of artificial resins may also be used, which, under the action of heat, form insoluble synthetic resins. In addition, solvents may be used as binders. water-soluble condensation products of phenol and formaldehyde or urea and formaldehyde and, after adding hardening agents, make them thermally insoluble. Finally, in addition to binders consisting of synthetic resins, other water-soluble binders, such as traganthus, for example, the following mixtures are used in the practice of the invention: EXAMPLE 1 28 parts methylene block, 45 graphite, 24 parts water-soluble condensation product of phenol and aldehyde (resole), 3 "softener. 100 Example IL 28 parts of eosin, 35 "kaolin, 10" calcium stearate, 22 "water-soluble urea condensate and formic aldehyde (eg, caurite) in a powder or solution, 5" tragant. 100 EXAMPLE IIL 28 parts of methylene blue, 20 "kaolin, 15" boil, 10 "calcium stearate, 22" dimethylurea and hardener (ester of formic acid), 5 "tragant." 100 The mixtures according to Examples I, II, or III are prepared by adding water to a dough plastic mass from which cores are formed by common pressing. The finished cores are so insensitive to moisture that even boiled in water According to the invention, writing, drawing, copying and color cores of all kinds, as well as bar-shaped writing implements, such as, for example, crayons for drawing and marking, can be manufactured.
