[0002] In the process of preparing ceramic wine bottles, pigments are usually added to the ceramic base material, so that the prepared ceramic wine bottles have different colors. In the prior art, the pigments are directly mixed with the ceramic base material. Generally, in order to present bright colors, To improve the color fixing ability of the pigment, the particle size of the pigment powder is usually small, but if the particle size is too small, it will easily cause the aggregation of the pigment powder, which will affect the uniform distribution of the pigment in the ceramic base material. It contains acid or alkali, and the main component of the pigment is inorganic oxides. Long-term use will cause the oxides in the wine bottle to corrode and dissolve in the wine, which will affect human health, and the color of the surface of the wine bottle will fade and lighten, affecting its beautiful color

Embodiment 1

[0018] A low-temperature anti-corrosion pigment for ceramic wine bottles, the specific preparation process is as follows:

[0019] Step 1: Weigh 100g of ferric chloride and add it to 1L of water. At the same time, add 11g of polyethylene glycol to the water and stir to dissolve to obtain a reddish-brown emulsion. Then add 15g of diatomaceous earth powder to the 100mL emulsion, and stir and mix for 20-30min , and then filtered and dried, and the dried powder was roasted in a muffle furnace at a temperature of 1000-1050 °C for 5-6 hours to obtain a reddish-brown powder;

[0020] In the second step, add 15 g of the reddish-brown powder prepared in the second step to 100 mL of the reddish-brown emulsion prepared in the first step, stir and mix for 40-50 min at room temperature, then filter and dry, and dry the The powder is placed in a muffle furnace at a temperature of 1000-1050°C and roasted for 5-6 hours to obtain a reddish-brown powder;

[0021] In the third step, the reddish...

Abstract

The invention discloses low-temperature anti-corrosion pigment for a ceramic wine bottle. The specific preparation process comprises steps as follows: a certain amount of polyvinyl alcohol is added towater, a red brown cementing mixture is prepared from a red brown pigment raw material and sodium silicate and calcined, and porous SiO2 shell coated pigment is obtained; ferric chloride and polyethylene glycol are stirred and mixed to obtain a red brown emulsion, the prepared porous SiO2 shell coated pigment is added to the red brown emulsion to be dipped, then, roasting is performed, and the surface of a product is coated with titanium dioxide; the pigment, sodium chloride and zinc oxide are mixed, ground and then calcined, and the low-temperature anti-corrosion pigment is obtained. By supporting two layers of iron trioxide, iron trioxide on the inner layer can still be protected by silicon dioxide when iron trioxide on an outer layer is corroded, corrosion of iron trioxide on the innerlayer can be effectively avoided, and the ceramic wine bottle can still keep the bright color unchanged through the color generation effect of iron trioxide on the inner layer.
