Product effect test
1. Latent heat of phase change calculation
By the preparation of Sr from examples 1-4 x Ba 1-x (Nb 0.6 Mn 0.4 ) 2 O 6 And the DSC data of the sample is analyzed, so that the heat absorbed by phase change, namely the phase change latent heat, can be calculated when the temperature of the sample is raised to the Curie temperature. The results of the phase change latent heat, peak temperature, phase change initiation temperature and phase change end temperature of the results obtained by the samples are shown in Table 1.
TABLE 1
2. Thermal insulation performance test
The coatings prepared in examples 1-4, examples 7-8 and comparative example 1 were tested for heat preservation and heat storage effects by simulating the irradiation of sunlight on a heated ceramic plate by using a xenon lamp under the same conditions, the heat preservation and heat storage properties of the coatings were proved by testing the surface temperature of the ceramic plate, and the test time was measured every 0.5h, and the results are shown in table 2.
TABLE 2
| Sample of | 0.5h | 1h | 1.5h | 2h | 2.5h | 3h |
| Comparative example 1 | 26.3℃ | 30.5℃ | 35.8℃ | 41.2℃ | 46.9℃ | 52℃ |
| Example 1 | 25.9℃ | 30℃ | 35.4℃ | 40.1℃ | 42.7℃ | 45.5℃ |
| Example 2 | 26.1℃ | 30.3℃ | 33.9℃ | 37.6℃ | 44℃ | 49.8℃ |
| Example 3 | 25.8℃ | 28.7℃ | 31.5℃ | 36.9℃ | 42.1℃ | 48.5℃ |
| Example 4 | 22.1℃ | 27℃ | 33.6℃ | 39.2℃ | 45℃ | 51.7℃ |
| Example 7 | 26℃ | 30.6℃ | 35.8℃ | 40.8℃ | 44.2℃ | 49.5℃ |
| Example 8 | 26.2℃ | 30.3℃ | 35.1℃ | 40.2℃ | 45.8℃ | 51.4℃ |
As can be seen from Table 2, the ceramic plates corresponding to examples 1-4 and examples 7-8 of the present invention have lower surface temperatures than comparative example 1 when the ambient temperature reaches the temperature near the Curie temperature of each coating, which indicates that the coating has obvious heat preservation and heat storage properties. The heat insulation effect of the coating corresponding to the embodiment 1-2 is obviously better than that of the embodiment 7-8, which shows that the selection of the types of the surfactants in the process of preparing the ink and the selection of stirring dispersion conditions have obvious influence on the heat insulation effect of the coating.
The thermal insulation effect of the coatings corresponding to examples 5-6 was similar to examples 3-4.
