Abstract

The invention discloses a preparation method for an acid-alkali-resistant adherent enamel plate, and belongs to the technical field of decorative materials. According to the preparation method for theacid-alkali-resistant adherent enamel plate, quick lime and water react with each other to generate calcium hydroxide, the calcium hydroxide reacts with sulfate in blast furnace slag to generate dihydrate gypsum, high-density sintering of glaze is facilitated, and then the enamel plate surface has the high hardness and wear resistance; heavy metal ions in the glaze of the blast furnace slag mostly exists in the form of the sulfate, the heavy metal ions in the glaze can achieve complexing with triethanolamine, hydrogen ions are consumed under the acidic condition, and aluminum ions in the glaze and the heavy metal ions generate hydrated silicate on the surface under the alkaline condition; and cobalt nitrate and nickel nitrate are taken as an adherence promoter for the glaze, the cobalt nitrate and the nickel nitrate are molten and decomposed into cobalt oxide and nickel oxide at the low temperature in the firing process, therefore, the adherence of the glaze can be improved, the highacid and alkali resistance is achieved, and the wide application prospect is achieved.

Description

technical field [0001] The invention discloses a preparation method of an acid and alkali resistant close-adhesive enamel plate, which belongs to the technical field of decorative materials. Background technique [0002] The enamel plate is a composite material in which the prepared enamel glaze is sprayed and fired, condensed on the base steel plate and firmly combined with the steel plate. It has the advantages of corrosion resistance, smooth and bright surface, good insulation, and convenient installation and maintenance. It is widely used in building walls and ceilings, commercial kiosks, billboards, subway inner walls, and tunnel inner walls. In recent years, people often use it as an ordinary writing board. As an ordinary writing board, the enamel board has the advantages of no dust, good insulation, and convenient installation and transportation. As a writing board, the board also has problems such as high brightness, poor visual effect, poor wear resistance, and ea...
