Embodiment 1

[0040] (1) Weigh the raw materials according to the mass parts of the following components:

[0041] Quartz 40kg, zero-water borax 22.0kg, soda ash 6.0kg, potassium carbonate 2.0kg, calcium carbonate 2.0kg, fluorite 4.5kg, potassium feldspar 15.0kg, albite 5.0kg, nickel oxide 1.5kg, copper oxide 1.2kg, Cobalt oxide 0.8kg, manganese oxide 2.0kg, iron oxide 2.0kg.

[0042] (2) Stir and mix the above raw materials evenly.

[0043] (3) Put the uniformly mixed materials into the melting furnace for melting. When melting, the melting furnace adopts pure oxygen environment, and the temperature is controlled at 1260±10°C for melting.

[0044] (4) After the above materials are completely melted, the borosilicate glass body is obtained, and the molten borosilicate glass body is brazed, and quickly pulled into a glass filament of 1.2 to 1.5 meters for testing. The testing requirement is: no glass filament within 1 meter. It takes 10 minutes to complete the melting process.

Embodiment 2

[0047] The preparation process of this embodiment is basically the same as that of Example 1, except that the mass parts of each component in step (1) are: 40 kg of quartz, 22.4 kg of zero-water borax, 5.5 kg of soda ash, 3.0 kg of potassium carbonate, and Calcium 2.0kg, fluorspar 4.5kg, potassium feldspar 14.7kg, albite 4.0kg, nickel oxide 1.5kg, copper oxide 1.2kg, cobalt oxide 0.8kg, manganese oxide 2.0kg, iron oxide 2.0kg.

[0048] In step (5), the process of rapidly cooling the melted borosilicate glass body is by tableting.

Embodiment 3

[0050] The preparation process of this embodiment is basically the same as that of Example 1, except that the mass parts of each component in step (1) are: 40 kg of quartz, 23.1 kg of zero-water borax, 4.5 kg of soda ash, 4.0 kg of potassium carbonate, and Calcium 2.0kg, fluorspar 4.5kg, potassium feldspar 14.6kg, albite 3.0kg, nickel oxide 1.5kg, copper oxide 1.2kg, cobalt oxide 0.8kg, manganese oxide 2.0kg, iron oxide 2.0kg.

Abstract

The invention discloses a nitrate-free environment-friendly steel plate enamel medium-temperature cobalt-nickel ground coat, a preparation method and application, and the formula of the nitrate-free environment-friendly steel plate enamel medium-temperature cobalt-nickel ground coat comprises the following components in parts by mass: 38-42 parts of quartz, 22-24 parts of borax anhydrous, 4-6 parts of sodium carbonate, 2-4 parts of potassium carbonate, 1.8-2.2 parts of calcium carbonate and 4-5 parts of fluorite. The invention relates to a high-strength ceramic material, which is prepared from the following components in parts by weight: 14.5 to 16 parts of potassium feldspar, 3 to 5 parts of albite, 1.4 to 1.6 parts of nickel oxide, 1.1 to 1.3 parts of copper oxide, 0.7 to 0.8 part of cobalt oxide, 2.0 to 2.2 parts of manganese oxide and 1.9 to 2.1 parts of iron oxide. The formula does not contain nitrate, a pure oxygen combustion mode is adopted in the melting process, and the major technical problem that in the production process of existing steel plate enamel medium-temperature cobalt-nickel ground glaze, nitrogen oxide (NOx) gas is generated and discharged to pollute the environment is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of enamel, and in particular relates to a medium-temperature cobalt-nickel underglaze for nitrate-free environment-friendly steel plate enamel, a preparation method and application. Background technique [0002] Enamel enamel is mainly composed of feldspar, quartz and other refractory raw materials, borax, sodium nitrate, potassium nitrate, soda ash and other fusible chemical raw materials, as well as characteristic raw materials such as non-ferrous metal oxides. They are mixed in a certain proportion, melted at high temperature, and rapidly cooled into granules or flakes. Shaped borosilicate glass bodies were prepared. [0003] The introduction of nitrates (sodium nitrate, potassium nitrate, etc.) into enamel glazes as oxidants and fluxes has become a consensus in the industry, and it is an indispensable raw material for enamel glazes in traditional enamel theory. So far, there is no safe, colorless, reaso...
