Semi-transparent ceramic sheet decorated with ink light-absorbance and preparation method thereof

A semi-transparent ceramic sheet decorated through ink light-absorbance, comprising:

• a semi-transparent green body,
• an inner inkjet pattern layer infiltrating into the semi-transparent green body from an upper surface of the semi-transparent green body,
• a decoloration glaze layer located on the upper surface of the semi-transparent green body, and
• a surface pattern layer located on the decoloration glaze layer,
• wherein the decoloration glaze layer is prepared by applying a decoloration glaze on the semi-transparent green body, and the formula of the decoloration glaze is:
• 0 to 9 parts by weight of ultra-white kaolin, 8 to 15 parts by weight of C30 soil, 15 to 35 parts by weight of quartz, 2 to 20 parts by weight of fused silica, 8 to 20 parts by weight of calcined talc powder, 20 to 35 parts by weight of potassium feldspar powder, 3 to 7 parts by weight of bentonite, and 0.5 to 5 parts by weight of nano zinc oxide;
• and
• wherein the inner inkjet pattern layer is prepared by applying a first inkjet infiltrating ink on the decoloration glaze which is capable of decoloring the first inkjet infiltrating ink in the decoloration glaze layer.
