As can be seen from Table 4, the anti-cracking ceramic tile provided by the invention not only can keep good breaking strength and Mohs hardness grade of the ceramic tile, but also has better breaking modulus, namely, the anti-cracking property of the ceramic tile is improved, wherein the breaking strength is 1950-1970N, the Mohs hardness grade is 3-5, and the breaking modulus is 55.1-65.6MPa.
It can be seen from the combination of example 1 and comparative example 1 that the tile of example 1 has 1950N of breaking strength, 3 on the mohs scale, and 55.1MPa of modulus of rupture, which is superior to that of comparative example 1, indicating that it is more suitable to modify basalt fiber with silane coupling agent in the raw material of the tile, not only to maintain excellent mechanical strength of the tile, but also to improve the modulus of rupture of the tile, i.e. to improve the crack resistance of the tile.
As can be seen by combining the embodiment 1 and the comparative example 2, the ceramic tile in the embodiment 1 has the breaking strength of 1950N, the Mohs hardness grade of 3 and the breaking modulus of 55.1MPa which are superior to the comparative example 2, and the modified basalt fiber is more suitable to be added into the raw materials of the ceramic tile, so that the ceramic tile can keep good breaking strength and Mohs hardness grade, also has better breaking modulus and improves the crack resistance of the ceramic tile.
As can be seen by combining example 1 and comparative example 3, the tile of example 1 has 1950N of breaking strength, 3-grade Mohs hardness and 55.1MPa of modulus of rupture, which is superior to that of comparative example 3, and shows that the sodium bentonite is more suitable for the raw materials of the tile, so that the tile not only maintains good breaking strength and Mohs hardness, but also has better modulus of rupture and improved crack resistance.
As can be seen by combining examples 1-5, the tile of example 5 has 1955N of breaking strength, 4 Mohs hardness scale and 59.4MPa of modulus of rupture, which is superior to other examples, and the modified basalt fiber of example 5 is added in a more appropriate amount, so that the tile not only has good mechanical strength, but also has improved crack resistance and better modulus of rupture.
Combining example 9 and examples 11-12, it can be seen that the tile of example 11 has a breaking strength of 1965N, a mohs hardness rating of 5, and a modulus of rupture of 65.2MPa, which is superior to other examples, indicating that the modified basalt fiber prepared by preparation example 2 is more suitable, and not only can the tile maintain good breaking strength and mohs hardness rating, but also has a better modulus of rupture, and the crack resistance of the tile is improved.
It can be seen from the combination of examples 11 and 13 that the tile of example 13 has a breaking strength of 1970N, a mohs scale of 5, and a modulus of rupture of 65.6MPa, which is superior to that of example 11, indicating that the modified basalt fiber is more suitably pretreated with a sodium hydroxide solution before use, and that the modified basalt fiber can enhance the binding property in the green body, and contribute to the improvement of the crack resistance of the tile, resulting in a better modulus of rupture of the tile.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of the present application is not limited by the embodiments of the present application, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
