The invention discloses a
honeycomb vacuum hole heat insulating
ceramic tile and a process for producing the same. The raw materials for the unburned
brick of the heat insulating
ceramic tile in weight percentage are: (1) 60 to 70 percent of kaolin, (2) 1 to 5 percent of
plastic foam particle, and (3) 20 to 30 percent of water; the raw materials for a glistening white
glaze by weight percentages are: (1) 50 to 65 percent of
silicon oxide, (2) 13 to 18 percent of aluminum
oxide, (3) 12 to 17 percent of
calcium oxide, (4) 0.5 to 1.5 percent of
magnesium oxide, (5) 3 to 4 percent of
sodium oxide, and (6) 1 to 1.5 percent of
potassium oxide; and the
plastic foam comprises but is not limited to
polyurethane plastic particle the
diameter of which is between 6 and 7 millimeters. The process for producing the
ceramic tile comprises the following steps: mixing and pressing various raw materials of the heat insulating ceramic tile into specified unburned bricks, naturally
drying the specified unburned bricks completely, spraying the glistening white
glaze on the specified unburned bricks, airing and then firing the specified unburned bricks to obtain the finished product. When the ceramic tile is fired into the finished product, a plurality of
honeycomb vacuum holes appear in the
brick body, the vacuum holes are not connected with each other and are kept at a constant temperature, thus the
honeycomb vacuum hole heat insulating ceramic tile has good heat insulating effect.
