Preparation method of self-repairing capsule based on carbonization effect, and self-repairing capsule
The invention discloses a preparation method of a self-repairing capsule based on carbonization effect, and the self-repairing capsule. According to a technical scheme in the invention, the preparation method of the self-repairing capsule based on the carbonization effect comprises the following steps: preparing capsule core particles, and wrapping the surfaces of the capsule core particles with inner capsule walls to form capsule particles with the inner capsule walls; carbonizing the capsule particles with the inner capsule walls under set conditions to obtain capsule particles with dense inner capsule walls; and spraying a PVA solution on the surfaces of the capsule particles with the dense inner capsule walls multiple times to form outer capsule walls so as to obtain self-repairing capsule particles. According to the invention, the problem that the mechanical properties of a matrix structure is affected due to insufficient hardness of an existing self-repairing capsule can be solved, and the hardness and strength of the capsule are improved by compacting an inner capsule wall structure through the carbonization effect.
本发明公开了一种基于碳化作用的自修复胶囊制备方法及自修复胶囊，其技术方案为：制备囊芯颗粒，在囊芯颗粒表面包裹内囊壁形成具有内囊壁的胶囊颗粒；将具有内囊壁的胶囊颗粒在设定条件下进行碳化处理，得到具有密实内囊壁的胶囊颗粒；在具有密实内囊壁的胶囊颗粒的表面多次喷涂PVA溶液以形成外囊壁，得到自修复胶囊颗粒。本发明可以解决现有自修复胶囊硬度不足而影响基体结构力学性能的问题，并通过碳化作用密实内囊壁结构从而提升胶囊的硬度和强度。
