Embodiment 1

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

[0041] Quartz 18.0kg, zero-water borax 25.0kg, soda ash 13.0kg, potassium carbonate 3.5kg, calcium carbonate 3.5kg, fluorite 11.5kg, potassium feldspar 22.0kg, albite 1.2kg, antimony oxide 0.6kg, nickel oxide 0.8kg , manganese oxide 2.6kg.

[0042] SiO in quartz 2 The mass proportion of ≥99.5%, SiO in potassium feldspar 2 The mass proportion of ≥71%, SiO in albite 2 The mass proportion of calcium fluoride is ≥71%, the mass proportion of calcium fluoride in fluorite is ≥95%, the mass proportion of Ni in nickel oxide is ≥71%, the purity of antimony oxide is ≥99.5%, and other raw materials are industrial-grade purity.

[0043] (2) Stir and mix the above raw materials evenly.

[0044] (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 1230±10°C for melting. ...

Embodiment 2

[0048] 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: quartz 18.0kg, zero-water borax 25.5kg, soda ash 13.0kg, potassium carbonate 2.8kg, Calcium carbonate 4.0kg, fluorspar 11.9kg, potassium feldspar 22.0kg, albite 1.6kg, antimony oxide 0.6kg, nickel oxide 0.8kg, manganese oxide 2.6kg.

[0049] In step (5), the process of rapidly cooling the melted borosilicate glass body is by tableting.

Embodiment 3

[0051] 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: quartz 18.0kg, zero-water borax 26.0kg, soda ash 13.0kg, potassium carbonate 1.5kg, Calcium carbonate 4.7kg, fluorspar 12.5kg, potassium feldspar 22.0kg, albite 2.0kg, antimony oxide 0.6kg, nickel oxide 0.8kg, manganese oxide 2.6kg.

Abstract

The invention discloses nitrate-free environment-friendly steel plate enamel low-temperature nickel ground glaze, a preparation method and application, and the formula of the nickel ground glaze comprises the following components in parts by mass: 16-20 parts of quartz, 25-27 parts of anhydrous borax, 12-14 parts of sodium carbonate, 1.5-3.5 parts of potassium carbonate, 3.5-5.0 parts of calcium carbonate, 11-13 parts of fluorite, 21-23 parts of potassium feldspar, 1-2 parts of albite, 0.7-0.9 part of nickel oxide and 0.5-0.6 part of antimony oxide. And 2.4 to 3.0 parts of manganese oxide. The formula of the low-temperature nickel ground glaze 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 low-temperature 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 nitrate-free environment-friendly low-temperature nickel undercoat for 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, reasonably price...
