Problems solved by technology

The enamel glazes currently on the market are suitable for low-carbon steel, cast iron, stainless steel and aluminum substrates. Cloisonne glazes are suitable for copper and a very small part of brass, gold, silver, etc., and for bronze enamel glazes. Development and research are extremely rare, and the technical problems faced are mainly due to the fact that the linear expansion coefficient of ordinary enamel glaze is higher or lower than that of bronze 17×10 -6 / °C, for example, the linear expansion coefficient of ordinary steel plate enamel glaze is about 10~13×10 -6 / °C, lower than the linear expansion coefficient of copper 17×10 -6 / °C, due to the large difference in expansion coefficient, internal stress is generated, which makes the ordinary enamel glaze and the bronze substrate unable to be firmly bonded

Embodiment 1

[0022] The making of embodiment 1 bronze enamel glaze

[0023] Weighing raw materials and dosage: 40.8 grams of borax decahydrate, 132.1 grams of albite feldspar, 25 grams of calcium fluoride, 75 grams of barium carbonate, 52.6 grams of calcium carbonate, 13.5 grams of nickel monoxide, 8.8 grams of zinc oxide, 139.8 grams of trilead tetraoxide grams, 39.9 grams of potassium carbonate, 68.6 grams of lithium carbonate, 332.6 grams of sodium nitrate, 59.5 grams of zircon sand, 6.8 grams of molybdenum trioxide, and 5 grams of alumina.

[0024] Production process: Mix the above raw materials evenly, melt them in an environment of about 1200 degrees Celsius to form a melt, and then quench the melt in cold water to obtain enamel frit, namely bronze enamel glaze. In the finished product of bronze enamel glaze, part of the raw materials are burnt out through the enamel melting stage, but they are all within the reasonable range that those skilled in the art can predict.

Embodiment 2

[0027] The making of embodiment 2 bronze enamel products

[0028] Apply the bronze enamel glaze prepared in the above embodiment on the bronze substrate to make bronze enamel products.

[0029] The production process is as follows:

[0030] (1) Pre-treatment of the bronze substrate: including cleaning the surface of the bronze substrate and sandblasting the surface of the bronze substrate.

[0031] Specifically, the surface of the bronze substrate is sandblasted, using extremely fine quartz sand, which is sprayed on the surface of the bronze substrate by air pressure to effectively remove surface pollutants, impurities, oxides, etc. If the surface of the bronze base material is rough and there are defects such as trachoma, the bronze base material after sandblasting can be soaked in the mixed liquid of dilute sulfuric acid and hydrogen peroxide until the bronze base material shows a copper red color. After taking it out, rinse it with clean water and sandblast it again .

Abstract

The invention discloses bronze enameled glaze which comprises 4-6 percent of borax decahydrate, 12-14 percent of albite, 2-3 percent of calcium fluoride, 6-8 percent of barium carbonate, 4-7 percent of calcium carbonate, 1-2 percent of nickel oxide, 0.5-2 percent of zinc oxide, 12-15 percent of lead tetraoxide, 2-5 percent of potassium carbonate, 5-8 percent of lithium carbonate, 32-35 percent of sodium nitrate, 5-7 percent of zircon sand, 0.5-1 percent of molybdenum trioxide and 0.5 percent of aluminum oxide. The invention also discloses a method for preparing the bronze enameled glaze, a bronze enameled product prepared by utilizing the bronze enameled glaze as well as a preparation method of the bronze enameled glaze. According to the invention, various problems such as porcelain explosion, cracks, firing shrinkage and the like in traditional copper enameled products are solved.

Description

technical field [0001] The invention belongs to the field of copper enamel production, and in particular relates to a bronze enamel glaze preparation method thereof and bronze enamel products produced by using the bronze enamel glaze. Background technique [0002] Enamel glaze is a vitrified or vitrified inorganic film fused on the metal surface. Its main function is to protect the underlying metal and beautify the appearance of metal products. Enamel products have both the mechanical strength of metal and the stability of glass, and have been widely used in people's daily life, such as tableware, kitchen utensils, wall panels, artworks and chemical industries. The enamel glazes currently on the market are suitable for low-carbon steel, cast iron, stainless steel and aluminum substrates. Cloisonne glazes are suitable for copper and a very small part of brass, gold, silver, etc., and for bronze enamel glazes. Development and research are extremely rare, and the technical pro...
