Embodiment 1

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

[0041] Quartz 24.8KG, zero-water borax 28KG, potassium carbonate 2KG, titanium dioxide 13.5KG, magnesium carbonate 2KG, trisodium phosphate 3.6KG, sodium fluorosilicate 8KG, potassium dichromate 0.12KG, potassium feldspar 11KG.

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

[0043] (3) Put the uniformly mixed material into a melting furnace for melting, and melt it under the condition of pure oxygen, and control the melting temperature at 1230±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 t...

Embodiment 2

[0047] The raw materials are weighed according to the mass parts of the following components:

[0048] Quartz 24.8KG, Zero Water Borax 29KG, Potassium Carbonate 2KG, Titanium Dioxide 13.5KG, Magnesium Carbonate 2KG, Trisodium Phosphate 3.6KG, Sodium Fluosilicate 7KG, Potassium Dichromate 0.12KG, Potassium Feldspar 10KG.

[0049] The preparation process of this example is basically the same as that of Example 1, the difference is that in step (5), the quenching of the melted borosilicate glass body adopts a tableting process.

Embodiment 3

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

[0052] Quartz 24.8KG, zero-water borax 30KG, potassium carbonate 2KG, titanium dioxide 13.5KG, magnesium carbonate 2KG, trisodium phosphate 3.6KG, sodium fluorosilicate 6.5KG, potassium dichromate 0.12KG, potassium feldspar 9KG.

[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 low-temperature titanium creamy yellow cover glaze and a preparation method thereof, and the nitrate-free environment-friendly steel plate enamel low-temperature titanium creamy yellow cover glaze comprises the following components in parts by mass: 23-25 parts of quartz, 27-30 parts of anhydrous borax, 3-5 parts of phosphate, 12-15 parts of titanium dioxide, 9-11 parts of potassium feldspar, 1-3 parts of magnesium carbonate and 1-3 parts of potassium carbonate. 6 to 8 parts by mass of sodium fluosilicate and 0.1 to 0.15 part by mass of potassium dichromate. 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 low-temperature titanium creamy cover glaze does not contain nitrate, and the major technical problem that in the production process of existing steel plate enamel low-temperature titanium creamy cover glaze, nitric 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 low-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 oxidizing a...
