Problems solved by technology

However, the existing glaze powder on the market has not been modified, has poor fluidity, is easy to block the equipment spray gun, and has poor electrostatic performance. When the electrostatic dry method is used for glazing, the film formation is uneven, which greatly affects the product quality and yield.

Abstract

The invention discloses matte glaze powder suitable for electrostatic spraying, and a preparation method thereof, and relates to the technical field of ceramic glaze. The matte glaze powder suitable for electrostatic spraying comprises, by weight, 70-75 parts of a matte glaze powder raw material, 15-20 parts of resin, 3-5 parts of a curing agent, 2-5 parts of an electrostatic auxiliary agent, 0.1-0.5 part of a wetting agent, 0.1-0.5 part of a leveling agent, and 1-3 parts of modified wax powder. The matte glaze powder is good in electrostatic spraying performance, uniform in film formation during electrostatic dry glazing and good in glaze effect.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a matte glaze powder suitable for electrostatic spraying and a preparation method thereof. Background technique [0002] With the rise of architectural ceramic explosives - rock slabs, more and more architectural ceramics companies in the industry have begun to produce large-size rock slabs, especially ultra-thin rock slabs (3~6mm). Extending to the direction of home decoration greatly broadens the application field of building ceramic materials. However, there are still some limitations in the glazing process in the production of large-scale ultra-thin rock slabs. Conventional bell jar glazing can easily lead to excessive water absorption and reduced strength of the green body, which affects the firing quality of the product; it is difficult to control the glazing with mixed air spray glazing Quantity, and uneven glazing; digital glaze use cost is high, and it is easy to...
