Comparative Example 4 (the Protective Glaze was a Conventional Protective Glaze that was Commercially Available)

[0238] The difference between this example and the example 3 above lay in:

[0239] In step E, the protective glaze was a conventional protective glaze that was commercially available.

[0240] The ceramic tiles decorated with dry particles prepared in examples 1-10 above and comparative examples 1-4 were tested for properties such as hardness, wear resistance, glossiness, and interlayer adhesion. The test results were as follows:

TABLE-US-00033 Adhesion grade Mohs Grade of wear of dry particle hardness resistance Glossiness layer Example 1 >7 4 8 0 Example 2 >7 4 7 0 Example 3 >7 5 5 0 Example 4 >7 4 6 0 Example 5 >7 4 8 0 Example 6 >7 4 7 0 Example 7 >7 4 6 0 Example 8 >7 5 5 0 Example 9 >7 4 6 0 Example 10 >7 4 7 0 Comparative 6.0 2 12 2 example 1 Comparative 5.0 3 9 1 example 2 Comparative 6.0 2 11 1 example 3 Comparative 6.0 3 10 1 example 4

[0241] Wherein, the grade of wear resistance was tested according to a test method of GB/T 3810.7-2016 Standard, and the degree of surface wear traces of samples after grinding at a specific grinding speed was observed. The grade of wear resistance is divided into 0-5 grades, and specific grades are as follows:

TABLE-US-00034 The number of grinding revolutions with Grade visible abrasion 0 100 1 150 2 600 3 750, 1500 4 2100, 6000, 12000 5 >12000

[0242] The adhesion grade of the dry particle layer was tested according to a cross-cut test method of GB/T9286-98 Standard, and shedding of the dry particle layer of the test sample was observed. The adhesion grade of the dry particle layer is divided into 0-5 grades, and specific grades are as follows:

TABLE-US-00035 Grade Description of situation 0 Edges are completely smooth, and there is no shedding. 1 There is shedding at an intersection of the cross-cut incision and/or an edge of the incision, but the effect of the cross- cut area is obviously not more than 5%. 2 There is shedding at an intersection of the cross-cut incision and/or an edge of the incision; an affected cross-cut area is obviously larger than 5%, but obviously not larger than 15%. 3 Part or all of a cutting edge is peeled off as large pieces, and/or partly or completely peeled off on different parts of each; an affected cross-cut area is obviously larger than 15%, but obviously not larger than 35%. 4 There are large fragments falling off along the edge of the incision, and/or partial or complete shedding appears in some squares; an affected cross-cut area is obviously larger than 35%, but obviously not larger than 65%. 5 A peeling degree exceeds 4 grades.

[0243] According to the test data above, the ceramic tiles made by the disclosure have clear patterns, distinct layers, low glaze glossiness, good non-slip effects, obvious senses of dry particles, strong three-dimensional effects, rich colors, high hardness, and high dry particle adhesion.

[0244] In comparative example 1, the common spreading process of dry particles on the market was adopted, and the dry particles were spread directly after the glue was spread on the green body. Compared with the ceramic tile prepared in each example of the present disclosure, the surface of the ceramic tile produced in comparative example 1 had lower wear resistance, a wear resistance grade of 2, lower dry particle adhesion, high glossiness (12°), lower slip resistance, a lower dry particle sense, and slightly lower hardness (6.0). This showed that, by spraying protective glaze after the dry particles were spread, then firing, or spraying the wetting agent and then spraying the glue, and then spreading the dry particles and spraying the protective glaze, through strict control of the sequence and process of each step condition, the present disclosure can make the green body of the ceramic tile and the dry particles form a stable bonding layer of body-particle-glaze. The ceramic tile of the present disclosure had an obvious sense of sand, an strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.

[0245] In comparative example 2, compared with Example 8, the glue was sprayed directly after the green body was dried, then the dry particles were spread and recovered, and finally the green body was fired after the protective glaze was sprayed. The surface of the ceramic tile produced had lower wear resistance, a wear resistance grade of 3, lower dry particle adhesion (grade 1), high glossiness (9°), lower slip resistance, a lower dry particle sense, and slightly lower hardness (5.0). This showed that the present disclosure can form a transparent wetting film on the surface of the glaze surface of the green body by spraying the wetting agent solution on the dried body, thereby increase the humidity of the product. Utilizing the hydrophilicity and lipophilicity of the wetting agent of the present disclosure, the subsequent glue is easier to be sprayed on the glaze, the adhesion of the glue on the glaze is improved, and the oily ink and glue on the glaze are prevented from being affected by the phenomenon of avoiding the glaze. This will affect the dispersion and stability of the subsequent bonding of dry particles to the surface of the green body. At the same time, by spraying the protective glaze, it can improve the wear resistance of the ceramic tile surface, reduce its glossiness, and have the effect of matte frosting; it can also make the green body of the ceramic tile and the dry particles form a stable bonding layer of body-particle-glaze, thereby the ceramic tile has an obvious sense of sand, an strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.

[0246] Compared with example 8, in comparative example 3, the protective glaze was not sprayed at the end of the process, and the ceramic tile produced had lower surface wear resistance, a wear resistance grade of 2, lower dry particle adhesion (Grade 1), high glossiness (11°), lower slip resistance, a lower dry particle sense, and slightly lower hardness (6.0). This showed that the present disclosure can spray the protective glaze on the surface of the dry particles evenly by spraying the protective glaze on the surface of the body after the dry particles was spread, and strictly controlling the spraying pressure and the amount of the protective glaze. It can protect the dry particles to ensure that the dry particles are not blown off or suctioned off during the kiln firing process, improve the adhesion of the dry particles on the surface of the green body, avoids causing the dry particles to adhere to the kiln wall or roof as a result of the dry particles being suctioned away, thereby preventing the product from ash contamination, limestone caves, pinholes, etc. At the same time, by spraying the protective glaze, it can improve the wear resistance of the ceramic tile surface, reduce its glossiness, and have the effect of matte frosting; it can also make the green body of the ceramic tile and the dry particles form a stable bonding layer of body-glue-particle-glaze, thereby the ceramic tile has an obvious sense of sand, an strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.

[0247] Compared with example 3, in comparative Example 4, the protective glaze used in the process was a commercially available conventional protective glaze instead of the raw material formula of the protective glaze of the present disclosure; the ceramic tile produced had lower surface wear resistance, a wear resistance grade of 3, lower dry particle adhesion (Grade 1), high glossiness (10°), lower slip resistance, a lower dry particle sense, and slightly lower hardness (6.0). This showed that spraying the protective glaze can protect the dry particles to ensure that the dry particles are not blown off or suctioned off during the kiln firing process, improve the adhesion of the dry particles on the surface of the green body, avoids causing the dry particles to adhere to the kiln wall or roof due to the dry particles being suctioned away, thereby preventing the product from ash contamination, limestone caves, pinholes, etc. At the same time, by spraying the protective glaze, it can improve the wear resistance of the ceramic tile surface, reduce its glossiness, and have the effect of matte frosting; it can also make the green body of the ceramic tile and the dry particles form a stable bonding layer of body-glue-particle-glaze, thereby the ceramic tile has an obvious sense of sand, an strong three-dimensional effect, a clear pattern, rich colors, high hardness, high adhesion of the dry particle layer, a difficulty of shedding, high surface wear resistance, low glossiness, and a good non-slip effect.
