Description
Vynález ee týká grafitového ochranného nátěru pro vysoké teploty, obsahujícího jako hlavni složku grafit.The invention relates to a high temperature graphite protective coating comprising graphite as a major component.
Pro ochranné nátěry za vysokých teplot se používá řada látek. Tam, kde ochranné nátěry za vysokých teplot se používá řada látek. Tam, kde ochranné nátěry máji být dobře tepelně vodivá a/nebo nesmáčivé taveniaami, se často používá grafit nebo grafit pojený vodním sklem. Tyto nátěry však často špatně na povrohu ulpívají a to především u kovů.A number of substances are used for high temperature protective coatings. Where high temperature protective coatings are used, many substances are used. Where protective coatings are to be well thermally conductive and / or non-wettable by melting, graphite or waterglass bonded graphite is often used. However, these coatings often do not adhere to the surface, especially with metals.
Uvedené nedstatky řeší podle vynálezu grafitový ochranný nátěr, obsahující jako hlavni složku grafit. Jeho podstata spočívá v tom, že obsahuje 50 až 98 % hmot. grafitu, 1,5 až 40 % hmot. oxidu hlinitého nebo směsi oxidu hlitnitého a chromitého v poměru 1:90 až 100:1 a 1,5 až 30 % hmot. oxidu fosforečného vnášeného výhodně jako kyselina fosforečná a/nebo fosforečnan hlinitý, ohromitý nebo amonný, dispergovaný ve vodě a/nebo ve vodě s mísícími se organickými rozpouštědly.According to the invention, the above-mentioned drawbacks are solved by a graphite protective coating containing graphite as the main component. It consists of 50 to 98 wt. % graphite, 1.5 to 40 wt. % alumina or a mixture of alumina and chromium trioxide in a ratio of 1:90 to 100: 1 and 1.5 to 30 wt. phosphorus pentoxide introduced preferably as phosphoric acid and / or aluminum, phosphate or ammonium phosphate dispersed in water and / or water with mixed organic solvents.
Účinek nátěru podle vynálezu spočívá především v dosažení velmi dobré přilnavosti na materiály včetně kovů, v dobré tepelné vodivosti a nesmáčivosti některými tavenina— mi. Dále má velmi dobrou chemickou odolnost. Fosforečná složka reaguje do určité míry s povrohem materiálů, na který je nanášen, a vytváří tak pevné spojení s povrchem.The effect of the coating according to the invention is primarily to achieve very good adhesion to materials including metals, good thermal conductivity and non-wettability by some melt. It also has very good chemical resistance. The phosphorous component reacts to some extent with the surface of the materials to which it is applied, thereby forming a firm bond with the surface.

Nátěr po nanesení je nutno nechat důkladně vysušit a pak fixovat výpalem, nejlépe na teplotu použití, nejméně však na teplotu 200 °C·After application, it is necessary to dry thoroughly and then fix it by firing, preferably to the temperature of use, but at least to 200 ° C ·
Maximální teplota použiti nátěru je v neutrální a redukční atmosféře 1200 až 1700 °0 podle složení, v oxidační atmosféře je limitována hořením grafitu a pohybuje se v rosme zí 500 až 700 °0.The maximum application temperature in a neutral and reducing atmosphere is 1200 to 1700 ° 0 depending on the composition, in an oxidizing atmosphere it is limited by the burning of graphite and ranges between 500 and 700 ° 0.
Nátěr se podle potřeby ředí vodou, eventuálně pro urychlení schnuti s vodou se mísícími organickými kapalinami, jako jsou například alkoholy, a to především alkoholem etylnatým·If necessary, the coating is diluted with water, possibly to speed up drying with water-mixed organic liquids such as alcohols, especially ethyl alcohol.
Nátěr podle vynálezu je dále popsán na několika příkladech provedeni·The coating according to the invention is further described in several exemplary embodiments.

Byl použit pro hlinito-křemičité žárovzčorné materiály, Bylo dosaženo nižší emáčivostl etruskou a taveninami·It was used for aluminosilicate refractory materials, lower wettability with Etruscan and melts. ·
Uvedené nátěry lze použít jako velmi dobře tepelně i elektricky vodivé při vyeokýoh teplotáoh, a to především v metalurgii, energetice a podobně· Jeou neemáčivé nebo málo emáčivé struskemi a podobnými taveninami·The mentioned coatings can be used as very thermally and electrically conductive at high temperatures, especially in metallurgy, power engineering and the like. They are non-wetting or low-emitting slag and similar melts.
