Example 5 is substantially the same as example 4 except that: the particle size of the anorthite is 0.5 mu m,10 mu m and 80 mu m; the mass ratio of the anorthite with the thickness of 0.5 mu to the anorthite with the thickness of 10 mu to the anorthite with the thickness of 80 mu is 1:2:1.
Comparative example 1
Example 1 is substantially the same as example 2 except that: 18 parts of quartz were used instead of 10 parts of quartz and 8 parts of anorthite.
Comparative example 2
Example 1 is substantially the same as example 2 except that: 8 parts of pyrolusite are used instead of 4 parts of pyrolusite and 4 parts of molybdenum oxide.
Comparative example 3
Example 1 is substantially the same as example 2 except that: does not contain melamine.
The glazes of examples 1 to 3 and comparative examples 1 to 4 were tested for performance by the following method:
1) Glazing the glaze on the surface of the daily ceramic body, and airing to obtain a glazed daily ceramic body;
2) Heating the glazed domestic ceramic blank from room temperature to 500 ℃ at a heating rate of 5 ℃/min, preserving heat for 3 hours, heating to 1350 ℃ at a heating rate of 9 ℃/min, and sintering for 4 hours; finally cooling to 800 ℃, preserving heat for 2 hours, and then cooling to room temperature to obtain the product.
Flexural strength was tested using GB/T4741-1999;
the tribological properties of the samples were tested using a ball-and-disc type tribometer.
The specific parameter results are shown in Table 1:
| flexural Strength (MPa) | Wear Rate (. Times.10) -4 ) | |
| Example 1 | 123.5 | 2.7 |
| Example 2 | 125.6 | 2.3 |
| Example 3 | 121.2 | 2.9 |
| Example 4 | 126.1 | 2.1 |
| Example 5 | 129.3 | 1.6 |
| Comparative example 1 | 110.4 | 4.1 |
| Comparative example 2 | 113.7 | 3.8 |
| Comparative example 3 | 102.9 | 4.6 |
By comparing examples 1-5 with comparative examples 1-3, the flexural strength and wear resistance are significantly improved with quartz and anorthite relative to quartz alone; by pyrolusite and MoO 3 The mechanical properties are obviously improved when the composite material is used in combination, and the mechanical properties and the wear resistance of the glaze layer are reduced after the melamine is omitted.
The above examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present invention should be made in the equivalent manner, and the embodiments are included in the protection scope of the present invention.
