Problems solved by technology

[0004] The existing burnt gold barrels made of enamel formula for forming an underglaze layer on the base metal have poor bonding and adhesion with the metal body, and are not compatible with the expansion coefficient of the metal body, resulting in the porcelain surface after firing. Poor, numbness, scorching spots, and cold bursts often occur, which seriously affect the quality and service life of the product

Abstract

The invention discloses nickel base porcelain glaze for a sintered metal drum and a production method thereof. The nickel base porcelain glaze is prepared from the following raw materials in parts by weight: 20-22 parts of feldspar, 23-27 parts of quartz, 24-32 parts of borax, 8-9 parts of sodium carbonate, 7-8 parts of sodium nitrate, 6.5-7 parts of fluorite, 1.5-2 parts of manganese oxide and 1-2 parts of nickel oxide. The production method comprises the following steps: melting the raw materials at a high temperature according to the formula, and then, rapidly cooling to form granular or flake-like borosilicate glass so as to obtain a nickel base porcelain glaze block; weighted by 100kg of nickel base porcelain glaze block, adding 5% of quartz, 0.3% of borax, 0.3% of sodium nitrite, 0.2% of sodium carbonate, 0.4% of antimony oxide, 0.02% of magnesium sulfate, 6.5% of Xu Yong clay, 48.00% of water and 115.00% of high-aluminum stone balls, uniformly mixing, and carrying out ball milling to obtain the porcelain glaze with the fineness of 80 meshes of a screen. After being sintered, the nickel base porcelain glaze is relatively good in porcelain surface and free of cold explosion.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and specifically relates to an enamel used for forming an underglaze layer on a base metal, and also relates to a production method of the enamel. Background technique [0002] Burning gold barrel is a kind of enamel barrel with holes in the barrel wall used for offering sacrifices and burning paper money and other sacrificial supplies. The existing production process is divided into blank making and glaze making (including melting glaze blocks and grinding them into glaze powder or glaze pulp), enamelling, firing, flower decoration and other processes. The base glaze is first applied to the pre-stamped or cast metal blank, and the top glaze is applied after firing (once or several times). The bottom glaze is a transitional layer combined with the metal blank. The top glaze is applied on the bottom glaze to cover the bottom color and give the product a smooth and beautiful surface and ...
