Abstract

The invention belongs to the technical field of enamel materials, and in particular relates to a vanadium-titanium enamel glaze and a preparation method thereof. The technical problem to be solved by the present invention is that the cost of vanadium-titanium enamel glaze is relatively high at present, the glossiness of fired enamel glaze surface is not enough, there is scale phenomenon, and the acid and alkali resistance is not enough. The solution of the present invention to solve the above-mentioned technical problems is to provide a vanadium-titanium enamel glaze, the ratio of raw materials is calculated in parts by mass: pretreated vanadium-titanium magnetite titanium tailings or vanadium-titanium extra-surface ore 22-28 20-22 parts of feldspar powder, 5-8 parts of quartz sand, 24-26 parts of borax, 1.5-2 parts of sodium nitrate, 3.5-5.5 parts of lithium carbonate, 5-7 parts of fluorite powder, 0.1-0.3 parts of sodium fluorosilicate 3-5 parts of cryolite, 2-4 parts of limestone, 3-4 parts of cobalt nitrate, 1-2 parts of nickel nitrate, 2-3 parts of sodium vanadate and 1-2 parts of antimony oxide. The vanadium-titanium enamel glaze material provided by the invention is firmly combined with the carbon steel body, and its acid and alkali resistance is better than the national standard, and can be used for various substrates of hot-rolled carbon steel and cast iron.

Description

technical field [0001] The invention belongs to the technical field of enamel materials, and in particular relates to a vanadium-titanium enamel glaze and a preparation method thereof. Background technique [0002] Enamel glaze is a material that covers the outside of the body after melting inorganic powders such as silicate and oxide at high temperature. The composition of enamel generally belongs to borosilicate glass, with a silicon content of more than 65%, high corrosion resistance and wear resistance, good surface finish, and easy cleaning. The structure is different from general ceramic coatings, and its outstanding feature is that it has glass properties. It belongs to the structure of long-range disorder and short-range order, in which there are a certain number and size of relatively regularly arranged micro-regions, so it has microscopic inhomogeneity, but from its macroscopic structure, it is uniform and disordered. The enamel coating not only has a smooth and ...
