Problems solved by technology

[0002] 3D printing technology is an emerging technology in the manufacturing industry and has great development prospects, but consumables have become a key factor restricting the wide application of 3D printing technology, and thermal insulation materials, as a kind of 3D printing consumables, have yet to be discovered.

[0003] At present, thermal insulation materials are mainly divided into organic thermal insulation materials and inorganic thermal insulation materials. Compared with organic thermal insulation materials, inorganic thermal insulation materials have a larger thermal conductivity and poor thermal insulation effect, but they are fire-resistant and flame-retardant, have better mechanical properties, and have a longer service life. ; The thermal conductivity of organic thermal insulation materials is small, and the thermal insulation effect is good, but it is easy to burn. Once a fire occurs, it will accelerate the spread of the fire, accompanied by a large amount of poisonous gas discharge

In addition, the existing thermal insulation materials have poor antibacterial effect and low safety in use
