Embodiment 1

[0043] (1) Take the raw materials by the mass parts of the following components:

[0044] Quartz 39KG, Zero Water Borax 33KG, Cobalt Oxide 0.012KG, Titanium Dioxide 15KG, Magnesium Carbonate 2KG, Sodium Tripolyphosphate 3.6KG, Sodium Fluosilicate 8KG, Potassium Carbonate 6KG, Aluminum Oxide 1.8KG.

[0045] (2) Stir and mix the above raw materials evenly.

[0046] (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.

[0047] (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.

[0048] (5) Quenching (water quenching) the melted borosilicate glass body to obtain the product.

Embodiment 2

[0050] The preparation process of this embodiment and embodiment 1 is basically the same, the difference is:

[0051] The mass parts of each component in the step (1) are: quartz 39KG, zero-water borax 34KG, cobalt oxide 0.012KG, titanium dioxide 15KG, magnesium carbonate 2KG, sodium tripolyphosphate 3.6KG, sodium fluorosilicate 7KG, potassium carbonate 5.5 KG, alumina 1.8KG.

[0052] In step (5), rapid cooling of the melted borosilicate glass body adopts a tableting process.

Embodiment 3

[0054] The preparation process of this embodiment and embodiment 1 is basically the same, the difference is:

[0055] The mass parts of each component in the step (1) are: quartz 39KG, zero-water borax 35KG, cobalt oxide 0.012KG, titanium dioxide 15KG, magnesium carbonate 2KG, sodium tripolyphosphate 3.6KG, sodium fluorosilicate 6.5KG, potassium carbonate 5KG, alumina 1.8KG.

Abstract

The invention discloses a nitrate-free environment-friendly steel plate enamel low-temperature titanium dioxide cover glaze and a preparation method thereof. The invention belongs to the technical field of enamel. The formula comprises the following components in parts by mass: 38-40 parts of quartz, 33-35 parts of borax anhydrous, 0.01-0.02 part of cobalt oxide, 14-16 parts of titanium dioxide, 1.8-2.5 parts of magnesium carbonate, 2-4 parts of sodium tripolyphosphate, 6-8 parts of sodium fluosilicate, 4-6 parts of potassium carbonate and 1.5-2 parts of aluminum oxide. 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 of the low-temperature titanium white cover glaze does not contain nitrate, and the major technical problem that in the production process of existing steel plate enamel low-temperature titanium white cover 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 steel plate enamel low-temperature titanium white surface 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 pr...
