The application of silicone in new energy vehicles
As countries around the world pay more and more attention to the environment, the global automobile industry is developing rapidly towards low carbon. New energy electric vehicles have become a mainstream trend, and the high requirements of science and technology and environmental protection are inseparable from the support of many high-tech new materials, among which silicone, which is regarded as "industrial MSG", is regarded as one of the indispensable new materials in the development process of new energy vehicles.
Organosilicon has its unique advantages. From a structural point of view, the "silicon-oxygen" main chain structure, the side chain is connected to other organic groups through silicon atoms, forming a typical inorganic-organic hybrid system, so that it can not break or decompose the chemical bond of the molecule at high temperature (or radiation irradiation). It has excellent high and low temperature resistance, weather resistance, electrical insulation, biocompatibility and other characteristics.
Silicone thermal conductivity materials used in new energy electric vehicles: One is the same parts as traditional cars, such as: various sensors, automotive electronics, vehicle displays, etc. The other is the only components of new energy electric vehicles, such as batteries, motors, electronic controls, chargers, etc. The types of adhesive products are sealant, thermal conductivity adhesive, thermal conductivity potting adhesive, thermal conductivity gel, thermal insulation material, thermal conductivity adhesive, foam silicone gasket, etc. These materials can be widely used in the above parts need bonding, sealing, insulation protection, mechanical buffering, thermal conductivity and other functions of the application.
The characteristics and advantages of mechanical silicon thermal conductivity materials are mainly in six aspects.
First, the applicable temperature range is wide, will not become soft and decomposed at high temperature, will not become hard and brittle at low temperature. Second, stable insulation performance, at different temperatures, and different use of the environment almost no change in insulation performance. Third, excellent strain and elastic properties. Fourth, the chemical property is stable, non-toxic, with physiological inertia, contact with the human body is safer. 5. Natural flame retardancy. Sixth, versatility, with a variety of functional components, silicone materials have good scalability, as a basic formula can be combined with a variety of other functional components, such as pigments, fillers, additives, etc., to develop a variety of functional materials, such as: thermal materials, conductive materials, foaming materials, coatings and so on.
