Embodiment 1

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

[0041] Quartz 28.8KG, zero-water borax 20KG, rutile 16.8KG, potassium feldspar 14KG, magnesium carbonate 3.5KG, potassium carbonate 3KG, sodium fluorosilicate 11KG, calcium carbonate 1.8KG, potassium dichromate 0.03KG.

[0042] (2) Pulverize the above raw materials and mix them evenly.

[0043] (3) Put the uniformly mixed material into the melting furnace, and melt it under the condition of pure oxygen, and the melting temperature is controlled at 1260±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 raw materials are weighed according to the mass parts of the following components:

[0048] Quartz 28.8KG, Zero Water Borax 21KG, Rutile 16.8KG, Potassium Feldspar 13KG, Magnesium Carbonate 3.5KG, Potassium Carbonate 3KG, Sodium Fluosilicate 10KG, Calcium Carbonate 1.8KG, Potassium Dichromate 0.03KG.

[0049] The preparation process of this embodiment is basically the same as that of Embodiment 1, except that in step (5), the process of quenching the melted borosilicate glass body is quenched by water.

Embodiment 3

[0051] The raw materials are weighed according to the mass parts of the following components:

[0052] Quartz 28.8KG, Zero Water Borax 22KG, Rutile 16.8KG, Potassium Feldspar 12KG, Magnesium Carbonate 3.5KG, Potassium Carbonate 3KG, Sodium Fluosilicate 9.5KG, Calcium Carbonate 1.8KG, Potassium Dichromate 0.03KG.

[0053] The preparation process of this embodiment is basically the same as that of embodiment 1.

Abstract

The invention discloses nitrate-free environment-friendly steel plate enamel medium-temperature titanium creamy yellow cover glaze and a preparation method thereof, and the nitrate-free environment-friendly steel plate enamel medium-temperature titanium creamy yellow cover glaze comprises the following components in parts by mass: 27-29 parts of quartz, 20-22 parts of anhydrous borax, 15-17 parts of rutile, 11-14 parts of potassium feldspar, 2-4 parts of magnesium carbonate, 2-4 parts of potassium carbonate and 9-11 parts of sodium fluosilicate. According to the invention, 1-2 parts by mass of calcium carbonate and 0.02-0.05 part by mass of potassium dichromate are melted at 1260 + / -10 DEG C under the condition of pure oxygen, and the firing temperature of the finished product is 800-830 DEG C. The medium-temperature titanium creamy glaze does not contain nitrate, and the major technical problem that in the production process of existing steel plate enamel medium-temperature titanium creamy glaze, nitrogen oxide 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 medium-temperature titanium milk yellow surface glaze and a preparation method thereof. Background technique [0002] Enamel enamel is mainly composed of refractory materials such as feldspar and quartz, fusible chemical materials such as zero-water borax, sodium nitrate, potassium nitrate, soda ash, and characteristic materials such as non-ferrous metal oxides. They are mixed in a certain proportion, melted at high temperature, and cooled rapidly into granular Or flake borosilicate glass body is 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 oxidizin...
