Description

Изобретение относится к технологии силикатов, в частности производству эмалевых покрытий, которые могут быть использованы для нанесения на изделия из чугуна и стали.The invention relates to the technology of silicates, in particular the production of enamel coatings, which can be used for application to products made of cast iron and steel.

Известно эмалевое покрытие, содержащее, мас. %: SiO2 41,0-43,0; TiO2 17,5-18,0; Al2O3 2,5-4,0; B2O3 16,0-16,5; MgO 1,0-1,5; K2O 8,5-9,0; Na2O 6,5-7,5; Р2О5 2,0-3,0; СаО 0,5-1,7; ZnO 2,0-4,0; ZrO2 4,0-5,0 [1]. Кислотостойкость такого эмалевого покрытия (потери в массе в 4% растворе СН3СООН) составит 0,045-0,06 мг/см2.Known enamel coating containing, by weight. %: SiO 2 41.0-43.0; TiO 2 17.5-18.0; Al 2 O 3 2.5-4.0; B 2 O 3 16.0-16.5; MgO 1.0-1.5; K 2 O 8.5-9.0; Na 2 O 6.5-7.5; P 2 O 5 2.0-3.0; CaO 0.5-1.7; ZnO 2.0-4.0; ZrO 2 4.0-5.0 [1]. The acid resistance of such an enamel coating (mass loss in a 4% solution of CH 3 COOH) will be 0.045-0.06 mg / cm 2 .

Задачей изобретения является повышение кислотостойкости эмалевого покрытия.The objective of the invention is to increase the acid resistance of the enamel coating.

Технический результат достигается тем, что эмалевое покрытие, включающее SiO2, TiO2, Al2O3, B2O3, MgO, K2O, СаО, дополнительно содержит MoO3, причем компоненты находятся при следующем соотношении, масс. %: SiO2 41,0-43,0; TiO2 13,0-17,0; Al2O3 24,0-27,0; В2О3 8,0-10,0; MgO 1,0-1,5; K2O 2,0-4,0; СаО 6,5-1,5; MoO3 2,5-4,0.The technical result is achieved in that the enamel coating, including SiO 2 , TiO 2 , Al 2 O 3 , B 2 O 3 , MgO, K 2 O, CaO, additionally contains MoO 3 , and the components are in the following ratio, mass. %: SiO 2 41.0-43.0; TiO 2 13.0-17.0; Al 2 O 3 24.0-27.0; B 2 O 3 8.0-10.0; MgO 1.0-1.5; K 2 O 2.0-4.0; CaO 6.5-1.5; MoO 3 2.5-4.0.

В таблице приведены составы эмалевого покрытия.The table shows the compositions of the enamel coating.

Варка фритты эмали может быть проведена при температуре ~1500°С. Расплавленную фритту гранулируют в холодную воду и размалывают с добавками: глины 5 мас. %, поташа 0,2 мас. %, воды 40 мас. % к 100 мас. % фритты. Полученную смесь наносят на загрунтованную металлическую поверхность и закрепляют оплавлением.Enamel frit can be cooked at a temperature of ~ 1500 ° C. The molten frit is granulated in cold water and ground with additives: clay 5 wt. %, potash 0.2 wt. %, water 40 wt. % to 100 wt. % frit. The resulting mixture is applied to a primed metal surface and fixed by reflow.
