Electrostatic wrapping liquid of vitreous enamel frit and electrostatic vitreous enamel powder and preparation method thereof

Abstract

The invention discloses electrostatic wrapping liquid of a vitreous enamel frit and electrostatic vitreous enamel powder and a preparation method thereof, and relates to the technical field of vitreous enamel. The electrostatic wrapping liquid is prepared from, by weight, 0.002-0.01 part of titanate coupling agents, 0.002-0.01 part of carboxyl modified-silicone oil, 0.002-0.01 part of silane coupling agents and 10-20 parts of industrial alcohol. The electrostatic vitreous enamel powder comprises the vitreous enamel frit and the electrostatic wrapping liquid, the electrostatic wrapping liquid accounts for 10%-20% of the total weight of the vitreous enamel frit, the vitreous enamel frit is smashed and then mixed with the electrostatic wrapping liquid by adding water, levigated and dried, and then the electrostatic vitreous enamel powder is prepared, The electrostatic wrapping liquid can wrap any vitreous enamel frit powder. The electrostatic vitreous enamel powder is easy to store, high in adsorption force, low in cost, high in non-flaming performance, free of volatility, resistant to dampness, acid and alkali, high in surface rigidity, good in toughness, high in impact resistance and durable in use. The preparation method of the electrostatic vitreous enamel powder is simple, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of enamel. Background technique [0002] The production of American dry-process electrostatic enamel powder needs to grind the enamel enamel frit to about 300 mesh and dry, and the moisture content should not exceed about 0.03%, so the operation is very troublesome and cumbersome. In addition, the enamel enamel frit powder after grinding and drying must react instantaneously with the coating liquid in the reactor. This kind of reactor equipment is relatively expensive, and there is no such equipment in our country at present. The price of its dry electrostatic enamel powder is about 26,000 yuan per ton, and it must be stored at a constant temperature. At present, the market demand for electrostatic enamel powder is very large, and most enterprises use the dry process electrostatic enamel powder of Ferro Company of the United States and Domade Company of Japan, which increases the production cost of the ente...
