Description

Изобретение относится к технологии силикатов, а именно к составам эмалей, которые могут быть использованы для покрытия изделий из чугуна, стали и других сплавов.The invention relates to the technology of silicates, and in particular to compositions of enamels that can be used to coat products from cast iron, steel and other alloys.

Известна эмаль, в состав которой входят SiO2, Al2O3, K2O SrO и другие компоненты [1]/.Known enamel, which includes SiO 2 , Al 2 O 3 , K 2 O SrO and other components [1] /.

Известна эмаль следующего состава, мас.%: SiO2 60,82-66,2; Al2O3 1,04-1,99; Na2O 9,29-10,3; K2О 6,47-6,98; SrO 9,63-10,83; Zi2O 4,69-5,17; Co2О3 1,56-1,77; Cr2O3 1,02-1,84; Fe2O3 0,1-0,3 [2].Known enamel of the following composition, wt.%: SiO 2 60.82-66.2; Al 2 O 3 1.04-1.99; Na 2 O 9.29-10.3; K 2 O 6,47-6,98; SrO 9.63-10.83; Zi 2 O 4.69-5.17; Co 2 O 3 1.56-1.77; Cr 2 O 3 1.02-1.84; Fe 2 O 3 0.1-0.3 [2].

Ударная прочность такой эмали составляет около 10 Дж.Impact strength of such enamel is about 10 J.

Целью изобретения является повышение ударной прочности эмали.The aim of the invention is to increase the impact strength of enamel.

Цель достигается тем, что в состав эмали дополнительно вводят NiO и MgO при следующем соотношении компонентов, мас.%: SiO2 50,0-55,0; Al2O3 1,0-2,0; K2O 6,0-8,0; SrO 8,0-10,0; Co2O3 1,0-2,0; Cr2О3 1,0-2,0; Fe2O3 1,0-2,0; NiO 6,0-8,0; MgO 17,0-20,0.The goal is achieved by the fact that NiO and MgO are additionally introduced into the enamel composition in the following ratio of components, wt.%: SiO 2 50.0-55.0; Al 2 O 3 1.0-2.0; K 2 O 6.0-8.0; SrO 8.0-10.0; Co 2 O 3 1.0-2.0; Cr 2 O 3 1.0-2.0; Fe 2 O 3 1.0-2.0; NiO 6.0-8.0; MgO 17.0-20.0.

В таблице приведены составы эмали.The table shows the compositions of enamel.
