POLYMER COMPOSITION FOR FILLING PIEZOCERAMIC TRANSMITTING-RECEIVING MODULES Russian patent published in 2015 - IPC C08L63/02 C08K3/10 C08K5/205 C08K5/16 C08G18/58 H01L41/193

Abstract RU 2552740 C2

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering for producing sealants and filling compounds and is intended for use in producing piezoceramic devices, particularly when producing ultrasonic transmitting-receiving modules for contactless fuel level sensors. The polymer composition includes epoxy diane resin, epoxy aliphatic resin, filling agents, an amine curing agent, modifying additives - cyclohexanol and a mixture of 2,4- and 2,6-isomers of toluene diisocyanate, and a filling agent. The filling agent in the composition is tungsten (VI) oxide and chromium (III) oxide. The polymer composition has high sound speed and acoustic impedance.

EFFECT: transmitting-receiving modules for fuel level sensors filled with the polymer composition have a high conversion coefficient and vibration resistance.
