Embodiment

[0029] A kind of lunar soil "concrete". After a certain proportion of lunar soil simulants and additives are uniformly mixed, a viscous mixed material system suitable for 3D printing of lunar surface facilities is prepared. The weight ratio of the mixed material system composed of lunar soil simulants and additives is: the mass of lunar soil simulants is calculated as 15kg, the mass fraction of magnesium oxide is 2.8kg, the mass fraction of magnesium chloride is 0.9kg, and the mass fraction of water It is 2kg.

[0030] A method for preparing lunar soil "concrete", the device used in the method includes a drive motor, a coupling, a screw extrusion device and a printing nozzle, such as Figure 1-3 As shown, the material of the print nozzle is nylon;

[0031] The driving motor is connected to the coupling, the coupling is connected to the screw extrusion device, and the printing nozzle is connected to the extrusion end of the screw extrusion device; the screw extrusion device ha...

Abstract

The invention relates to a lunar soil "concrete" and a preparation method thereof, and the lunar soil "concrete" is mainly used for aerospace, aviation, architectural paint and other technical fields. Lunar soil "concrete" hybrid 3D printing technology is an important key technology for follow-up lunar surface base construction of the moon in the future. A lunar soil simulant hybrid 3D printing device can realize continuous and controllable extrusion molding of lunar soil "concrete" by designing a lunar soil simulant hybrid 3D printing head. The hybrid 3D printing head is a key component of the lunar soil hybrid printing device, and can be employed to realize the continuous and controllable extrusion of lunar soil "concrete". The hybrid 3D printing head is a functional component integrating a drive motor, a coupling, a screw pump, an interface, a screw extrusion apparatus, a printing nozzle and other parts, and can realize the continuous and controllable extrusion molding of lunar soil "concrete" material.

Description

technical field [0001] The invention relates to a lunar soil "concrete" 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 important support for our ...
