Photocuring additive manufacturing method for converting low-shrinkage polymer into ceramic wave-absorbing material
The invention relates to a photocuring additive manufacturing method for converting a low-shrinkage polymer into a ceramic wave-absorbing material. The photocuring additive manufacturing method of the low-shrinkage polymer converted ceramic wave-absorbing material comprises the following steps: mixing a ceramic precursor with photosensitive resin and a photoinitiator to obtain a photosensitive ceramic precursor, then adding an inorganic solid-phase filler and a coupling agent into the photosensitive ceramic precursor, and mixing to obtain photosensitive ceramic precursor slurry; printing by taking the photosensitive ceramic precursor slurry as a raw material through a photocuring additive manufacturing technology to prepare a polymer conversion ceramic green body; and performing ultraviolet light aging and heating aging on the polymer converted ceramic green body, and then performing pyrolysis and high-temperature annealing to obtain the low-shrinkage polymer converted ceramic wave-absorbing material.
本发明涉及一种低收缩聚合物转化陶瓷吸波材料的光固化增材制造方法。所述低收缩聚合物转化陶瓷吸波材料的光固化增材制造方法包括：将陶瓷前驱体与光敏树脂、光引发剂混合得到光敏陶瓷前驱体，然后向光敏陶瓷前驱体中加入无机固相填料和偶联剂，混合得到光敏陶瓷前驱体浆料；以光敏陶瓷前驱体浆料为原料，通过光固化增材制造技术打印制备聚合物转化陶瓷生坯；将聚合物转化陶瓷生坯进行紫外光老化、加热老化，然后经热解、高温退火，得到所述低收缩聚合物转化陶瓷吸波材料。
