[0028] The steps adopted in the preparation method of the above-mentioned full-glazed ceramic tile with metallic effect are as follows:
[0029] Step 1. Raw materials for the billet are prepared by batching and ball milling to obtain a slurry, then iron removal, sieving, aging, spray milling, and then sieving to obtain a billet;
[0030] Step 2, the blank is pressed and formed by a press to prepare a green body;
[0031] Step 3, putting the green body into a drying kiln for drying;
[0032] Step 4, apply the surface glaze by glazing;
[0033] Step 5, carry out decorative printing by inkjet printing equipment;
[0034] Step 6. Print the metallic glaze by screen printing;
[0035] Step 7. Full polish by screen printing;
[0036] Step 8, entering the glaze kiln for firing;
[0037] Step 9, polishing;
[0038] Step 10, edging, quality inspection, and packaging.
[0039] Wherein, the raw material formula in the step 1 is as follows in parts by mass: 12-22 parts of stone powd...

[0048] The raw material is mixed with 12 parts of stone powder, 7 parts of Yonghe mud, 12 parts of Zhongshan mud, 9 parts of high alumina sand, 29 parts of Xinfeng sand, 25 parts of medium temperature sand, 3 parts of Zhuhai mud, and 3 parts of talc, and the method is wet ball milling After 11 hours of ball milling, iron removal, and sieving, the fineness of the slurry is 250 mesh sieve, and the sieve residue is 1.6 grams; the slurry is made into powder through a spray drying tower, and the moisture content of the powder is 6.5%. Grading: 0~1.5% for above 20 mesh, 30~60% for -20~+40 mesh, 72~88% for -20~+60 mesh, 0~6% for below 100 mesh, and -60~+100 mesh for the remainder; Prepare the powder and set aside.
[0049] The surface glaze is prepared according to 15 parts of calcined talc, 20 parts of potassium feldspar, 5 parts of zirconium silicate, 8 parts of frit, 30 parts of quartz, 15 parts of kaolin, 5 parts of calcined kaolin, and 4 parts of alumina. Method, ball milling f...
Embodiment 2
[0054] The preparation and product specifications of the powder, surface glaze and full glaze and the pressing frequency of the press are the same as in Example 1.
[0055] The metal flower glaze is prepared according to 30 parts of DS00670 transparent glaze, 60 parts of DS00677 transparent glaze, 75 parts of metal particles, and 70 parts of printed glue; its specific gravity is 1.55g / cm 3 , after passing through a 320-mesh sieve, the sieve residue is 0.1 g; the metal flower glaze is prepared and set aside.
[0056] The powder is pressed into a green body by a press, and dried at 160°C for 40 minutes; the surface glaze is directly applied on the dried green body through the glaze pouring equipment, and then the inkjet printing equipment is used for inkjet decorative printing; and then three 80-mesh different Line effect screen printing 3 lines of metallic flower glaze of the same color above; then use 80 mesh effect screen to print 2 lines of full polished glaze, and then use ...
