Preparation process of porous cement-based material compatible with electromagnetic shielding and infrared protection
The invention discloses a preparation process of a porous cement-based material compatible with electromagnetic shielding and infrared protection, which comprises the following steps: (1) adding a water phase into an oil phase, stirring until the water phase is dispersed, then carrying out polymerization reaction under heating and stirring conditions, then separating out a solid product, and washing to obtain a spherical high-water-absorption organic polymer; and (2) adding the spherical super absorbent organic polymer into a liquid phase for soaking, then adding the obtained gel substance into a magnetic nanoparticle dispersion medium containing a surfactant, stirring for reaction, separating out a solid product, and washing to obtain the spherical core-shell structure magnetic nanoparticle modified super absorbent organic polymer. And (3) doping the high-water-absorption organic polymer into a cement-based material, preparing slurry, and curing to obtain the porous cement-based material, which not only has a good electromagnetic shielding effect, but also remarkably reduces heat radiation generated in the electromagnetic wave consumption process, reduces infrared detectability, and enables the cement-based material to have better concealment.
本发明公开一种电磁屏蔽兼容红外防护的多孔水泥基材料制备工艺，包括步骤：（1）将水相加到油相中搅拌至分散，然后在加热和搅拌条件下进行聚合反应，然后分离出固体产物，洗涤得到球形高吸水有机聚合物。（2）将所述球形高吸水有机聚合物加到液相中进行浸泡，然后将得到的凝胶物质加到含有表面活性剂的磁性纳米粒子分散介质中，搅拌反应后分离出固体产物，洗涤后即得球形的核壳结构磁性纳米粒子改性高吸水有机聚合物。（3）将所述高吸水有机聚合物掺加到水泥基材料中，制成浆料后养护，即得多孔水泥基材料，其不仅具有良好的电磁屏蔽效果，而且显著降低了电磁波消耗过程中产生的热辐射，降低了红外可探测性，使所述水泥基材料具有更好的隐蔽性。
