Table 1
Embodiment 4-5
Embodiment 4-5 the difference is that only that the activation temperature of attapulgite clay is different from embodiment 3.Embodiment 4-5
The temperature for activating attapulgite clay is respectively 250 DEG C, 270 DEG C.
Comparative example 2
Comparative example 2 the difference is that only that the activation temperature of attapulgite clay is different from embodiment 3.Comparative example 2 activates
The temperature of attapulgite clay is 290 DEG C.
Test case
Mineral wool board and common commercially available mineral wool board prepared by Example 1-3 and comparative example 1, reference standard JC-T 2040-
In the case that 2010 investigations use above-mentioned mineral wool board, the amount of inducing of anion in air.Test result is as shown in table 2.
Table 2
| The negative aeroion amount of inducing (s.cm2) | |
| Embodiment 1 | 720 |
| Embodiment 2 | 890 |
| Embodiment 3 | 1850 |
| Embodiment 4 | 945 |
| Embodiment 5 | 1169 |
| Comparative example 1 | 370 |
| Comparative example 2 | 305 |
| Common commercially available mineral wool board 1 | 350 |
| Common commercially available mineral wool board 2 | 420 |
From table 2 it can be seen that not adding mineral wool board and common commercially available mineral wool board phase prepared by anion miberal powder with comparative example 1
Than the amount for the negative aeroion that the mineral wool board of the embodiment of the present application 1-5 addition anion miberal powder preparation induces out significantly increases,
It is apparently higher than 500/(s.cm2) standard, illustrate that the mineral wool board of the embodiment of the present application 1-5 can be released effectively anion.And
And the increase of the additive amount with anion miberal powder, the amount for the negative aeroion that the mineral wool board of embodiment 1-3 preparation induces out
Increase.
