Embodiment 1

[0021] The mass percent of the raw material formula of this example is: 70% of quartz sand, 4% of potassium feldspar, 5% of kaolin, 6% of sodium carboxymethyl cellulose, and 15% of red pigment. Proportion according to the formula, wet grinding in a planetary ball mill for 5 minutes, material: ball = 1:1.5, sodium carboxymethyl cellulose: water = 1:40. Glaze the surface of the tiles, the thickness of the glaze layer is 1mm when it is not dry, and dry at room temperature for 10h until the glaze layer is dry. Put the dried tiles in a resistance furnace for high-temperature firing, the heating rate is 7.2°C / min, the maximum firing temperature is 1230°C, the holding time is 20min, and cool with the furnace. The glaze surface of the product is rough, the quartz sand particles are fine and evenly distributed, the overall shape is simple and generous, the hand feels comfortable, and the base glaze is well combined.

Embodiment 2

[0023] The weight ratio of the raw material formula of this example is: 80% of quartz sand, 2% of potassium feldspar, 3% of kaolin, 4% of sodium carboxymethyl cellulose, and 11% of navy blue colorant. Proportion according to the formula, wet grinding in a planetary ball mill for 30 minutes, material: ball = 1:1.5, sodium carboxymethylcellulose: water = 1:50. Glaze the surface of the tiles, the thickness of the glaze layer is 2mm when it is not dry, and dry at room temperature for 12 hours until the glaze layer is dry. The dried tiles are fired in a resistance furnace at a high temperature, the heating rate is 7.2°C / min, the maximum firing temperature is 1250°C, the holding time is 15min, and they are cooled with the furnace. The glazed surface of the product has a matte effect, with delicate concave-convex lines on the surface, the particle size of the quartz sand is small, the hand feels comfortable, and the base glaze is well bonded.

Embodiment 3

[0025] The weight ratio of the raw material formula of this example is: 80% of quartz sand, 2% of potassium feldspar, 3% of kaolin, 4% of sodium carboxymethyl cellulose, and 11% of brown pigment. Proportion according to the formula, wet grinding in a planetary ball mill for 5 minutes, material: ball = 1:1.5, sodium carboxymethyl cellulose: water = 1:40. Glaze the surface of the tiles, the thickness of the glaze layer is 1.5mm when it is not dry, and dry it at room temperature for 12 hours until the glaze layer is dry. Put the dried tiles in a resistance furnace for high-temperature firing, the heating rate is 7.2°C / min, the maximum firing temperature is 1230°C, the holding time is 15min, and cool with the furnace. The glaze surface of the product is rough, the quartz sand is large in size, evenly distributed, comfortable to the touch, and well bonded to the glaze.

Abstract

The invention discloses a preparation method for a colored sand glaze ceramic tile. The tile is prepared from 70-80 parts of quartz sand, 2-4 parts of potash feldspar, 3-5 parts of kaolin, 4-6 parts of carboxymethyl cellulose sodium and 11-15 parts of pigment. According to the preparation method, the quartz sand is taken as a main raw material, a certain amount of carboxymethyl cellulose sodium isadded to improve a suspension property of glaze slip, and the defect of constant stirring in the glazing process of an original preparation process is solved, the method applied to bathroom floor tiles not only is simple and convenient to glaze, but also has skidproof and decorative effects. Because the raw material cost is low, the sintering temperature is not high, the product has more color varieties, the color is bright, firm, enduring, resistant in scratch, fadeless and resistant in a high temperature, and the method has significant economic benefits and social benefits.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a method for manufacturing colored sand glaze tiles. Background technique [0002] Colored sand can be generally divided into natural colored sand and artificial colored sand. Natural colored sand is crushed from natural ore. It does not fade but has more impurity colors and fewer colors. The preparation process is complicated. Artificial colored sand is based on quartz sand and coated with a layer of color-developing materials on its surface, such as chrysanthemum yellow, medium gray, blue gray, and other colors. Therefore, artificial colored sand has the advantages of bright colors and many varieties. Most of the color-developing materials of the layer are polymer materials, which are not resistant to high temperature, and are easy to lose color due to carbonization in a high-temperature environment, and the preparation process is more complicated. As artificial colored sand...
