Embodiment 1

[0040] (1) Take the raw materials by the mass parts of the following components:

[0041] Quartz 42KG, borax 27KG, potassium feldspar 6KG, lithium carbonate 5KG, titanium dioxide 5KG, soda ash 7.5KG, sodium fluorosilicate 6.5KG, zinc oxide 0.5KG;

[0042] (2) Stir and mix the above-mentioned raw materials;

[0043] (3) Put the uniformly mixed material into the melting furnace, and melt it under the condition of pure oxygen, and control the melting temperature at 1290±10°C;

[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 drawn into a glass filament of 1.2 to 1.5 meters for detection. The detection requirement is: within 1 meter of the glass filament. The knot is the completion of melting.

[0045] (5) Quenching and quenching the melted borosilicate glass body with water to obtain the product.

Embodiment 2

[0047] The preparation process of this embodiment and embodiment 1 is basically the same, the difference is:

[0048] The mass parts of each component in the step (1) are: quartz 42KG, borax 28KG, potassium feldspar 6KG, lithium carbonate 5KG, titanium dioxide 5KG, soda ash 8KG, sodium fluorosilicate 6KG, zinc oxide 0.5KG.

[0049] In step (5), rapid cooling of the melted borosilicate glass body adopts a tableting process.

Embodiment 3

[0051] The preparation process of this embodiment and embodiment 1 is basically the same, the difference is:

[0052] The mass parts of each component in the step (1) are: quartz 42KG, borax 25KG, potassium feldspar 6KG, lithium carbonate 5KG, titanium dioxide 5KG, soda ash 8KG, sodium fluorosilicate 6KG, zinc oxide 0.5KG.

Abstract

The invention discloses a nitrate-free environment-friendly cast iron enamel acid-resistant transparent glaze and a preparation method thereof, and belongs to the technical field of enamel, the nitrate-free environment-friendly cast iron enamel acid-resistant transparent glaze comprises the following components by mass: 40-45 parts of quartz, 23-28 parts of borax, 5-8 parts of potassium feldspar, 4-6 parts of lithium carbonate, 4-6 parts of titanium dioxide, 5-8 parts of sodium carbonate, 4-7 parts of sodium fluosilicate, and 0.3-0.5 part of zinc oxide. The raw materials are uniformly mixed according to the proportion and are molten under the condition of pure oxygen at 1290 + / -10 DEG C, and the firing temperature of the finished product is 760-780 DEG C. The formula does not contain nitrate, so that the technical problem of environmental pollution caused by emission of nitrogen oxide (NOx) gas generated in the production and processing process of the existing cast iron enamel acid-resistant transparent glaze is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of enamel, and in particular relates to a nitrate-free and environment-friendly cast iron enamel acid-resistant transparent glaze and a preparation method thereof. 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 priced oxidi...
