Embodiment 1

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

[0041] Quartz 24.5KG, Zero Water Borax 28KG, Potassium Feldspar 10.8KG, Calcium Carbonate 1.8KG, Titanium Dioxide 11KG, Magnesium Carbonate 0.9KG, Copper Oxide 2.2KG, Sodium Fluosilicate 9KG, Soda Ash 2KG.

[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 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. 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] Weigh raw materials according to the mass parts of the following components: Quartz 24.5KG, Zero Water Borax 29KG, Potassium Feldspar 10.8KG, Calcium Carbonate 1.8KG, Titanium Dioxide 11KG, Magnesium Carbonate 0.9KG, Copper Oxide 2.2KG, Sodium Fluosilicate 8KG, 1.5KG of soda ash.

[0048] The preparation process of this example is basically the same as that of Example 1, except that in step (5), the quenching of the melted borosilicate glass body adopts the process method of tableting.

Embodiment 3

[0050] The raw materials are weighed according to the mass parts of the following components:

[0051] Quartz 24.5KG, zero-water borax 30KG, potassium feldspar 10.8KG, calcium carbonate 1.8KG, titanium dioxide 11KG, magnesium carbonate 0.9KG, copper oxide 2.2KG, sodium fluorosilicate 7KG, soda ash 1KG.

[0052] 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 titanium lake blue cover glaze and a preparation method thereof, and the nitrate-free environment-friendly steel plate enamel titanium lake blue cover glaze comprises the following components in parts by mass: 22-25 parts of quartz, 28-30 parts of borax anhydrous, 11-14 parts of titanium dioxide, 9-11 parts of potassium feldspar, 0.7-1 part of magnesium carbonate, 1-2 parts of sodium carbonate, 7-9 parts of sodium fluosilicate and 1-2 parts of calcium carbonate. And 1.5-2.5 parts by mass of copper oxide. The raw materials are uniformly mixed according to the proportion and are molten under the condition of pure oxygen at 1260 + / -10 DEG C, and the firing temperature of the finished product is 800-830 DEG C. The titanium lake blue cover glaze does not contain nitrate, and the major technical problem that the environment is polluted due to emission of nitric oxide gas generated in the production process of existing steel plate enamel titanium lake blue cover 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 environment-friendly steel plate enamel titanium lake blue 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 and fluxing materia...
