Test result
The coefficient of permeability and electro-magnetic wave absorption value of embodiment 1 ~ 11 and comparative example 1 ~ 2 are tested, the results are shown in Table 1.
Table 1
As shown in Table 1, the effect of the electromagnetic wave absorption of the embodiment of the present invention 1 ~ 11 is better than comparative example 1, and comparative example 1 is common
Water-permeable brick, and the coefficient of permeability of embodiment 1 ~ 11 is all higher than 1 × 10-2Cm/s meets the water permeability requirement of water-permeable brick；
Comparative example 2 is added to reduction-oxidation graphite-ferroso-ferric oxide composite wave-suction material, does not add monkey grass and sepiolite
The effect of fiber, the electromagnetic wave absorption of comparative example 2 is better than comparative example 1, but 2 water permeability of comparative example is not so good as comparative example 1, is not inconsistent
Close the water permeability requirement of water-permeable brick, it may be possible to because being added to reduction-oxidation graphite-ferroso-ferric oxide composite wave-suction material, lead
Water-permeable brick porosity is caused to decline, the water permeability of water-permeable brick declines.Therefore, addition absorbing material may influence water-permeable brick merely
Water permeability, need to add monkey grass and sepiolite fibre, ensure the porosity of water-permeable brick, make the coefficient of permeability of water-permeable brick
Meet the performance requirement of water-permeable brick.
The effect of the electromagnetic wave absorption of embodiment 1 ~ 7 is better than embodiment 8, it is seen that aoxidizes three by reduction-oxidation graphite-four
Water-permeable brick prepared by iron composite wave-suction material is better than water-permeable brick prepared by ferroferric oxide powder, it may be possible to due to oxygen reduction fossil
In ink-ferroso-ferric oxide composite wave-suction material, reduction-oxidation graphite can prevent ferriferrous oxide particles from assembling so that four oxidations
Three-iron particle size smaller is more uniformly spread, surface area bigger, and the effect of the water-permeable brick electromagnetic wave absorption of preparation is more preferable.
The effect for implementing 1,5,6 electromagnetic wave absorption is better than embodiment 4 and embodiment 7, it is seen that-four oxygen of reduction-oxidation graphite
When ferroso-ferric oxide content is 80wt% ~ 90 wt% in change three-iron composite wave-suction material, the absorption electromagnetism for the water-permeable brick being prepared
The performance of wave is more preferable, it may be possible to which when being more than 90 wt% due to ferroso-ferric oxide content, the reduction-oxidation graphite-ferroso-ferric oxide is multiple
Ferriferrous oxide particles size bigger, the distribution for closing absorbing material are not uniform enough；And ferroso-ferric oxide content be less than 80 wt% when,
Ferroso-ferric oxide content reduces, and leads to the performance for the water-permeable brick electromagnetic wave absorption that the absorbing material for adding same weight is prepared
Decline, in order to enhance the performance of electromagnetic wave absorption, then needs that more absorbing materials are added, the water penetration of water-permeable brick may be influenced
Energy.
The anti-folding breaking load of embodiment 1 ~ 11 reaches the performance requirement of water-permeable brick, in addition, implementing 1 ~ 7 anti-folding destruction
Load is higher than embodiment 8, it is seen that and after ferroso-ferric oxide composite reduction graphite oxide, anti-folding breaking load is improved, so
Reduction-oxidation graphite can promote the toughness of water-permeable brick, fracture resistance.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to this hair
The restriction of bright embodiment.For those of ordinary skill in the art, it can also do on the basis of the above description
Go out other various forms of variations or variation.There is no necessity and possibility to exhaust all the enbodiments.It is all in the present invention
Spirit and principle within made by all any modification, equivalent and improvement etc., should be included in the guarantor of the claims in the present invention
Within the scope of shield.
