POLYMER COMPOSITE MATERIAL Russian patent published in 2021 - IPC C08L81/06 C08L79/08 C08K9/04 C08G73/16 B29C64/10 

FIELD: additive technology.

SUBSTANCE: invention relates to the field of creating polymer composite materials intended for use in the additive technology (3D printing). The polymer composite material is based on a mixture of polyphenylene sulphone and polyetherimide at a ratio of 50:50 pts. wt. and organomodified clay, and additionally includes polycarbonate at the following ratio, prs. wt.: polyphenylene sulphone/polyetherimide 100, polycarbonate 23 to 28, 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 guanidine-containing salts in the amount of 5% of the mass of montmorillonite.

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