High dielectric constant silastic used for electric stress control and preparation method and application thereof

Abstract

The invention provides a high dielectric constant silastic used for electric stress control and a preparation method and an application thereof. The silastic is prepared by the following components according to parts by weight: 40-70 parts of organopolysiloxane, 1-6 parts of organic hydrogenated polysiloxane, 0.8-3.0 parts of fluorine silicon multipolymer, 10-80 parts of base rubber, catalyst with routine type and routine dosage and inhibitor; the base rubber comprises the following components according to parts by weight: 30-45 parts of fumed silica treated by hydrophobization with organosilicon compound adopted, 25-40 parts of acetylene black and 10-20 parts of BaTiO3. The invention also provides a preparation method of the above silastic, comprising the following steps: each component and one or more of appropriate platinum catalyst, palladium catalyst or rhodium catalyst and/or butynol inhibitor are subjected to blending, refining, filtering and remilling to prepare the silastic. The invention also provides an application of the silastic, namely, the prepared gross rubber is sliced, extruded and formed by vulcanization to prepare the high dielectric constant silicone rubber tube.

AI Technical Summary

Benefits of technology

This patented technology describes two technical benefits that make it better than previous methods like adding metal foils or plating layers on top of existing materials. These improvements result in improved conductive capacity and reduced resistance at specific locations within the cable's structure. Additionally, this improvement allows for easier manufacturing processes while still providing effective protection against external factors such as water vapor and other gases from entering through openings between different parts of the device. Overall, these advancements lead to increased safety during operation and longer lifespan of the devices themselves.

Problems solved by technology

Technological Problem addressed in this patented paper includes issues associated with current methods of producing electromechanically stable and reliable power supply components like those made up of interconnected strands of copper wire bundles. Existing solutions involve adding extra layers of protectors around the outer edges of the component, increasing its dimensions during manufacturing processes, resulting in decreased operational safety and reduced throughput compared to more efficient ways of producing them.
