TABLE 3
Table 3 shows the results of the tests performed in the same space and at the same decibel level, in which the sound-absorbing energy-storing luminescent materials of examples 1 and comparative examples 1 to 5 were installed on the same wall surface at the same position and the same area.
As can be seen from table 3, the sound absorption effect of example 1 is the best, and compared with comparative example 1, perlite and pumice are both sound absorption materials, but the sound absorption energy storage luminescent material obtained by combining perlite and energy storage luminescent paint has better sound absorption effect than the sound absorption energy storage luminescent material obtained by combining pumice and energy storage luminescent paint.
And the size of the pumice stone of comparative example 2 and comparative example 3 is outside the optimal range of the application, and comparative example 2 and comparative example 3 have better sound absorption effect compared with comparative example 5 and comparative example 1, but the sound absorption effect of comparative example 2 and comparative example 3 is inferior to that of example 1, so when the size of the pumice stone is within the optimal range of the application, the pumice stone has better sound absorption effect, and when in use, the pumice stone can be better combined with the energy storage luminous coating, and the energy storage luminous coating can be further saved, and the cost is saved.
Comparative example 4 has better sound absorption effect compared with comparative example 1 and comparative example 5, but comparative example 4 has poorer sound absorption effect compared with example 1, and compared with the preparation by a traditional stirring method, the preparation by a spray gun method can better exert the performance of the material and improve the use efficiency.
