For the purpose of facilitating an understanding of the present invention, the present invention will now be described by way of examples. It should be understood by those skilled in the art that the examples are only for the understanding of the present invention and should not be construed as the specific limitations of the present invention.
Example 1
The preparation method of the foam fire extinguishing material comprises the following steps:
3 parts of APG, 13 parts of functional auxiliary agent (0.5 part of sodium benzoate and 12.5 parts of alcohol ester dodeca), 0.06 part of titanium dioxide, 0.03 part of black quartz sand and 60 parts of silicone oil are mixed for 2 hours to obtain the foam fire extinguishing material. The obtained foam fire-extinguishing material is subjected to reflectivity test, and as can be seen from fig. 1, the obtained black foam fire-extinguishing material (curve 2) has poor light reflection performance relative to the white foam fire-extinguishing material (curve 1), but has good light absorption performance; as can be seen from figure 2, the foam fire extinguishing material (curve 2) added with titanium dioxide is higher in light reflection rate than the foam fire extinguishing material (curve 1) not added with titanium dioxide, and the black material cannot absorb all light rays, so that the black material with the light reflection effect is adopted, the light rays which cannot be absorbed can be reflected, and the isolation maximization of the component and the light rays is further achieved.
Example 2
The difference from example 1 is that the black quartz sand is 0.01 parts.

Comparative example 2
The difference from example 1 is that the black silica sand was 0.06 parts.
Comparative example 3
The difference from the example 1 is that the reflectivity test is carried out on the obtained foam fire extinguishing material without adding titanium dioxide, and the result is shown in figure 2, and the graph shows that the foam fire extinguishing material without adding titanium dioxide (curve 1) has poorer light reflecting performance than the foam fire extinguishing material with adding titanium dioxide (curve 2).
Comparative example 4
The difference from example 1 is that the titanium dioxide is 0.11 part.
Comparative example 5
The difference from example 1 is that the black silica sand was replaced with zinc oxide as a white colorant, and as can be seen from fig. 1, the obtained white foam fire-extinguishing material (curve 1) has a strong light-reflecting property with respect to the black foam fire-extinguishing material (curve 2), but it cannot reflect all light.

the prepared foam fire extinguishing material is subjected to the following performance tests:
(1) and (3) testing the light absorptivity: and testing the light absorption rate of the foam fire extinguishing material by adopting an ultraviolet spectrophotometer.
(2) And (3) testing the light reflectivity: and testing the light reflectivity of the foam fire extinguishing material by adopting a reflectivity tester.

As can be seen from table 1, the foam fire extinguishing materials obtained in embodiments 1 to 5 of the present invention have good light absorption and light reflection due to the presence of titanium dioxide and black quartz sand, so as to maximize the isolation between the photovoltaic module and light, and the photovoltaic module has low power generation efficiency, the light absorption rate is greater than or equal to 83%, the light reflection rate is greater than or equal to 10%, and the power generation efficiency is less than or equal to 0.2%.
As can be seen from Table 1, the light absorption rate of the comparative example 1 is lower than that of the example 1, and the power generation efficiency is higher, probably because the content of the black quartz sand in the comparative example 1 is too small, the obtained foam fire extinguishing material has poor light absorption effect, so that the photovoltaic module absorbs more light sources, and the light absorption rate of the comparative example 1 is lower than that of the example 1, and the power generation efficiency is higher.
As can be seen from table 1, in comparative example 2, the light absorption rate, the light reflectance and the power generation efficiency are not much different from those in examples 1 to 5, which indicates that the content of the black silica sand is too much, which does not improve the light absorption and wastes resources.
As can be seen from Table 1, the light reflectivity of the comparative example 3 is lower than that of the example 1, and the power generation efficiency is higher, probably because titanium dioxide is not added in the comparative example 3, the obtained foam fire extinguishing material has poor reflection effect on light, so that the number of light sources absorbed by the photovoltaic module is larger, and the light reflectivity of the comparative example 3 is lower than that of the example 1, and the power generation efficiency is higher.
As can be seen from Table 1, in comparative example 4, compared with examples 1 to 5, the differences between the light absorption rate, the light reflectivity and the power generation efficiency are not large, which indicates that the excessive content of titanium dioxide has no promotion effect on the light reflectivity and wastes resources.
As can be seen from table 1, comparative example 5 has higher light reflectance, but no light absorption, and higher power generation efficiency than example 1, and may be because the black silica sand is replaced by the white colorant zinc oxide in comparative example 5, and the obtained foam fire extinguishing material is a white foam fire extinguishing material, and the white foam fire extinguishing material has no absorption effect on light, but cannot reflect all light rays although the reflectivity is strong, so that the photovoltaic module absorbs more light sources, and thus comparative example 5 has higher power generation efficiency than example 1.
