Abstract

The invention relates to a lunar soil concrete suitable for extrusion and a preparation method thereof, which are mainly used in technical fields such as aerospace, aviation, and architectural coatings. The lunar soil "concrete" hybrid 3D printing technology is an important key technology for the construction of the future lunar base. The lunar soil simulant hybrid 3D printing device can realize continuous and controllable printing by designing the lunar soil simulant hybrid 3D printing head. Extrusion of lunar soil "concrete". The hybrid 3D printing head is a key component of the lunar soil hybrid printing device, which is used to realize the continuous and controllable extrusion of lunar soil "concrete". It is a functional component that integrates drive motors, couplings, screw pumps, interfaces, screw extrusion devices, printing nozzles and other components to realize the continuous and controllable extrusion of lunar soil "concrete" materials.

Description

technical field [0001] The invention relates to a lunar soil "concrete" suitable for extrusion and a preparation method thereof, which are mainly used in technical fields such as aerospace, aviation, and architectural coatings. Background technique [0002] my country's Chang'e lunar exploration project development plan has successfully completed the two stages of "circling" and "falling", and is about to start the third stage of "returning". Establishing long-term living and scientific research bases on the moon is becoming more and more achievable plan. The establishment of large-scale moon-based facilities can bring many benefits. It can rely on the advantages of the moon’s lack of atmosphere to better carry out scientific activities such as space observation. It can become an outpost for human beings to engage in scientific research in the future, and it can exploit the rich lunar soil resources that exist on the moon. , can rely on the moon as a platform to provide imp...
