COMPOSITE MATERIAL Russian patent published in 2021 - IPC C08L81/06 C08K9/04 C08K3/34 C08K7/14 B29C64/10 

FIELD: additive technology.

SUBSTANCE: invention relates to the field of creating composite materials intended for use in the additive technology (3D printing). The composite material is based on polyphenylene sulphone, polycarbonate, and fibreglass and additionally includes organomodified clay, at the following ratio, pts. wt.: polyphenylene sulphone 100, polycarbonate 32 to 35, fibreglass 1 to 3, organomodified clay 0.5 to 2. The organomodified clay constitutes a product of modification of montmorillonite clay with a cation exchange capacity of 95 mg-eq/100 g of clay with urea in the amount of 7% of the mass of montmorillonite.

EFFECT: production of polymer materials complying with the requirements for physical and mechanical characteristics and hygroscopicity, intended for the additive technology.
