发布时间：2018-08-07 14:26
【摘要】：以石墨、磁性铁氧体为电磁波吸收剂,制备出泡沫水泥基吸波材料。随着发泡剂掺量的增加,材料孔隙率逐渐增大,干密度减小,抗压强度下降。当发泡剂掺量从6.0%增加到7.0%时,体系中增加的气孔形成了有利于材料力学性能的孔结构,抗压强度不降反增,在7.0%掺量时达到最大值2.91 MPa。此外,向材料中填加玄武岩纤维可以在泡沫水泥基材料中形成三维乱向的网络结构,提高材料的抗压强度。当纤维掺量为1.0 kg/m~3时最大抗压强度达到3.25 MPa。
[Abstract]:The foam cement based absorbing material was prepared by using graphite and magnetic ferrite as electromagnetic wave absorbers. With the increase of foaming agent content, the porosity increases gradually, the dry density decreases and the compressive strength decreases. When the amount of foaming agent was increased from 6.0% to 7.0%, the pore structure was formed in favor of the mechanical properties of the material, and the compressive strength was increased instead of decreasing, and the maximum value of 2.91 MPA was obtained when the content of foaming agent was increased from 6.0% to 7.0%. In addition, adding basalt fiber to the material can form a three-dimensional disorderly network structure in the foam cement-based material, and improve the compressive strength of the material. The maximum compressive strength reached 3.25 MPA when the fiber content was 1.0 kg / m ~ 3.
