Embodiment Construction

[0011] The preparation method of the present invention is carried out according to the following steps:

[0012] (1) Carry out the preparation of catalyst first, prepare pure titanium dioxide sol, adjust the pH value of sol, make the sol-type titanium dioxide photocatalyst of corresponding pH value,

[0013] (2) Carry out the coating of catalyst, make the sol-type titanium dioxide photocatalyst by 5~50mL / m 2 The amount of the photocatalytic ceramics with adjustable surface gloss is obtained by spraying, pulling, brushing or dipping on the surface of the ceramics, and then heat-treated or directly dried. The heat treatment conditions are: 100-600 ° C, time 10 to 120 minutes.

[0014] The preparation of the above catalyst is to hydrolyze titanium alkoxide (such as tetraisopropyl titanate, tetrabutyl titanate) under the condition of acidic pH<5 to obtain a uniform and transparent sol, and adjust the sol by dialysis according to the glossiness. The pH value is a certain value in

Abstract

The invention relates to a method for producing photocatalysis ceramics with adjustable surface gloss, which is characterized in that: the production method includes the following steps: (1) preparing catalyst at first, preparing pure titanic oxide sol, adjusting pH of sol, and producing sol type titanic oxide photocatalyst with corresponding pH value,(2) coating with sol type titanic oxide photocatalyst with dosage of 5-50 mL/m in spray finishing, lifting, brushing or dipping type on the surface of ceramics, for producing photocatalysis ceramic with adjustable surface gloss by heat-treatment or direct cooling and drying, wherein, the heat treat condition is: at 100-600 DEG C for 10-120 minutes. The method not only has simple steps, but also can be used for producing ceramics with required glossiness according to the design requirement.
