Problems solved by technology

[0002] The enamel glaze is used to enamel on the metal body, and it is composed of an alkali-boron-silicate glassy substance. The enamel glaze is applied to the metal body, and it can be firmly combined with the body after firing. The green body has protective and decorative functions; the existing cast iron enamel products are tested according to the cast iron enamel grade performance test specification, and the acid resistance grade can only reach B or B+ grade. The enamel currently used in the enamel glass industry is general acid-resistant enamel. Alkaline cannot meet the requirements of alkaline medium users, the alkali corrosion index of ordinary acid-resistant glaze is 7g / 24h m 3 ;It can only meet the application of weak alkali medium below 60°C, and it is difficult to meet the needs of customers with strong alkali medium above 60°C

Abstract

The invention discloses a cast-iron enamel glaze slip with high acid resistance, alkali resistance and burst resistance and a preparation method thereof. The cast-iron enamel glaze slip with high acidresistance, alkali resistance and burst resistance is prepared by the following materials by weights: glaze block 42-53%, quartz 6-10%, enamel pigment 3-5%, borax 0.3-0.5%, nitric acid 0.3-0.5%, sodaash 0.4-0.7%, cobalt dioxide 3%-10%, and the balance of water balance, wherein the quartz is quartz of 325-1000 mesh. The beneficial effects comprise that adding zirconium dioxide to the cast-iron enamel glaze slip can greatly improve the alkali resistance of enamel, and a finished product made of the cast-iron enamel glaze slip has a high acid resistance grade, good corrosion resistance, wear resistance, alkali resistance and quenching resistance. The preparation method of the cast-iron enamel glaze slip with high acid resistance, alkali resistance and burst resistance is simple in process,suitable for large-scale production, high in production efficiency and low in cost.
