Abstract

The invention discloses a nitrate-free environment-friendly steel plate enamel medium-temperature acid-resistant ground coat, a preparation method and application, and the formula of the nitrate-free environment-friendly steel plate enamel medium-temperature acid-resistant ground coat comprises the following components in parts by mass: 48-52 parts of quartz, 24-26 parts of anhydrous borax, 7-9 parts of sodium carbonate, 1.5-1.7 parts of manganese oxide, 0.8-1.0 part of nickel oxide and 1.0-1.1 parts of cobalt oxide. The formula comprises the following components in parts by weight: 2.8 to 3.6 parts of calcium carbonate, 1.2 to 1.8 parts of sodium fluosilicate, 2.0 to 3.0 parts of titanium dioxide, 1.2 to 1.5 parts of potassium feldspar, 5 to 6 parts of lithium carbonate and 0.4 to 0.8 part of fluorite. The formula provided by the invention does not contain nitrate, and a pure oxygen combustion mode is adopted in the melting process, so that the major technical problem that the environment is polluted due to emission of nitrogen oxide (NOx) gas generated in the production process of the existing steel plate enamel medium-temperature acid-resistant ground coat 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 steel plate enamel medium-temperature acid-resistant bottom glaze, a preparation method and an 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, rea...
