Introduction Electromagnetic absorption (EMA) materials have attracted extensive attention for electromagnetic protection and stealth [1-3].
Fig. 1 shows SEM images of spherical carbonyl iron powder and flake carbonyl iron powder under different ball grinding time.
It can be seen from Fig. 1(a) that the SCI particles are approximately spherical, with a diameter of about 1-6 µm.

It can be concluded that increasing the ratio of DAHP/urea from 2/1 to 4/1 has a negative effect on the flame retardant properties.
Fig.1.
Fig. 2 shows the test results of samples of tapestry fabric treated with flame-retardants in the ratio DAHP/urea = 3/1.
