Spherical water-absorbent resin-based reinforced 3D printing electromagnetic wave-absorbing concrete
The invention relates to reinforced 3D printing electromagnetic wave-absorbing concrete based on spherical water-absorbent resin, the concrete comprises a cement-based material and spherical water-absorbent resin, in the mixing and stirring process of the spherical water-absorbent resin and the cement-based material, uniform mixing needs to be guaranteed, the spherical water-absorbent resin does not expand obviously, printing slurry is obtained, and the printing slurry is applied to 3D printing. The printing slurry is conveyed into a printing spray head of a 3D printer for 3D printing; the sample obtained after 3D printing is protected with a protective film, regular maintenance and watering are conducted, the concrete is completely solidified one day later, a permanent spherical water-absorbent resin expansion supporting state is formed, and then water maintenance and drying are conducted for 28 days, so that the spherical water-absorbent resin reinforced 3D printing electromagnetic wave-absorbing concrete with regular air holes is obtained. The spherical water-absorbent resin is creatively used for preparing the 3D printing electromagnetic wave-absorbing concrete, and the electromagnetic wave-absorbing performance of the 3D printing electromagnetic wave-absorbing concrete is remarkably improved.
本发明为基于球状吸水树脂增强3D打印电磁吸波混凝土，所述混凝土中包括水泥基材料和球状吸水树脂，所述球状吸水树脂与水泥基材料混合搅拌过程中，既要保证混合均匀，又要保证球状吸水树脂未发生明显膨胀，获得打印浆料，将打印浆料送至3D打印机的打印喷头内进行3D打印；对3D打印后的试样用保护膜进行保护，并定时养护浇水，一天之后混凝土完全凝固，形成永久的球状吸水树脂膨胀支撑状态，再进行28d水养干燥后获得具有规则空气空穴的基于球状吸水树脂增强3D打印电磁吸波混凝土。开创性的将球状吸水树脂用于制备3D打印电磁吸波混凝土，显著提高3D打印电磁吸波混凝土的电磁吸波性能。
