Embodiment 1

[0041] (1) Take the raw materials by the mass parts of the following components:

[0042] Zero water borax 21KG, potassium feldspar 27KG, quartz 25KG, soda ash 10.4KG, sodium fluorosilicate 7KG, titanium dioxide 3KG, fluorite 5.6KG;

[0043] (2) Stir and mix the above-mentioned raw materials;

[0044] (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 1230±10°C;

[0045] (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 detection. The detection requirement is: within 1 meter of the glass filament 1 ~2 knots is the completion of melting.

[0046] (5) Quenching (pressing) the melted borosilicate glass body to obtain the product.

Embodiment 2

[0048] The preparation process of this embodiment and embodiment 1 is basically the same, the difference is:

[0049] The mass parts of each component in the step (1) are: zero-water borax 19.5KG, potassium feldspar 27KG, quartz 25KG, soda ash 11.5KG, sodium fluorosilicate 7.8KG, titanium dioxide 3KG, fluorite 5KG.

[0050] In step (5), quenching the melted borosilicate glass body adopts a water-induced process.

Embodiment 3

[0052] The preparation process of this embodiment and embodiment 1 is basically the same, the difference is:

[0053] The mass parts of each component in the step (1) are: zero-water borax 21.5KG, potassium feldspar 27KG, quartz 25KG, soda ash 9KG, sodium fluorosilicate 6.5KG, titanium dioxide 3KG, fluorite 4.4KG.

Abstract

The invention discloses nitrate-free environment-friendly steel plate enamel low-temperature transparent glaze and a preparation method thereof, and belongs to the technical field of enamel, and the formula comprises the following components in parts by mass: 19-22 parts of borax anhydrous, 26-28 parts of potassium feldspar, 24-26 parts of quartz, 9-12 parts of sodium carbonate, 6-8 parts of sodium fluosilicate, 2-4 parts of titanium dioxide and 4-6 parts of fluorite. The raw materials are uniformly mixed according to the proportion and are molten under the condition of pure oxygen at 1230 + / -10 DEG C, and the firing temperature of the finished product is 760-790 DEG C. The formula does not contain nitrate, and 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 low-temperature transparent glaze for steel plate enamel 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 transparent glaze for steel plate enamel 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 ox...
