MULTILAYER ACCEPTOR ASSEMBLY FOR INDUCTION HEATING OF AEROSOL FORMING SUBSTRATE Russian patent published in 2022 - IPC A24F40/465 

FIELD: tobacco industry.

SUBSTANCE: group of inventions relates to a multilayer acceptor assembly for induction heating of substrate, as well as to an aerosol generating product. The multilayer acceptor assembly for induction heating of aerosol forming substrate contains at least the first layer containing the first acceptor material, the second layer tightly attached to the first layer, containing the second acceptor material having a Curie temperature below 500°C, and the third layer tightly attached to the second layer, containing specific material compensating the voltage and having a specific layer thickness, so that after layers are tightly attached to each other and/or after heat treatment of the multilayer acceptor assembly, the third layer applies a tensile or compressive stress to the second layer at least in the compensation temperature range to counteract the compressive or tensile stress applied by the first layer to the second layer. The compensation temperature range extends at least from a temperature that is 20°C lower than the Curie temperature of the second acceptor material to the Curie temperature of the second acceptor material.

EFFECT: improvement of a multilayer current collector to preserve properties and effects of layers during its assembly and processing.
