A kind of bromobutyl rubber dielectric elastomer composite material and preparation method thereof

Abstract

The invention relates to a brominated butyl rubber dielectric elastomer composite material and a preparation method thereof. The preparation method comprises the steps that 100 parts of brominated butyl rubber, 1.5-9 parts of a vulcanization system, 10-50 parts of high-dielectric ceramic packing and 10-50 parts of a polarity plasticizer are blended by mass, even mixing is performed at the temperature of 20 DEG C-60 DEG C, slice discharging is performed, mixed rubber stands for 7-16 h at room temperature and then is vulcanized on a plate vulcanizer, and the brominated butyl rubber dielectric elastomer composite material is prepared. According to the brominated butyl rubber dielectric elastomer composite material and the preparation method thereof, the brominated butyl rubber is taken as a matrix, the dielectric ceramic packing with the high dielectric constant and the small-molecule polarity plasticizer are added into the matrix, and the prepared dielectric elastomer composite material has the advantages of being high in dielectric constant, low in elasticity modulus and excellent in ductility; meanwhile, high electrodeformation can be obtained in a lower external electric field, and the condition that in a traditional method, a dielectric elastomer only can generate high electrodeformation under the high voltage is improved.
