Organosiloxanes, also known as polysiloxanes, are a class of polymers that consist of silicon atoms and oxygen atoms alternately linked to form a skeleton, and different organic groups are then linked to silicon atoms.This special composition and molecular structure make silicone resin combine organic properties with inorganic functions, and have a series of unique properties, such as good chemical stability, strong weather resistance, high mechanical strength, and excellent insulation properties. These characteristics make it widely used in the energy industry.The following is a detailed introduction to the specific applications of silicone resins in the energy industry：
1. Solar photovoltaic modules
Packaging material
Application: Silicone resin is widely used in the packaging of photovoltaic modules because of its excellent weather resistance, electrical insulation and light transmittance.It can effectively isolate water vapor and oxygen, protect photovoltaic cells from environmental erosion, and extend their service life.In addition, by adjusting the molecular structure, the silicone resin can also improve the transmittance of light and enhance the photoelectric conversion efficiency of the battery.
Specific products: Silicone resin encapsulation glue serves as a key barrier to protect photovoltaic cells from water vapor and oxygen erosion. Its performance is directly related to the power generation efficiency and long-term stability of photovoltaic modules.Because of its low stress shrinkage, high light transmittance and excellent chemical resistance, silicone resin has become the preferred component in the packaging glue formula.
Innovative applications: for example, one-component room temperature vulcanized silicone rubber is used as a frame sealant for solar cells, junction box sealant, busbar sealant, and film assembly bracket adhesive.This kind of silicone rubber is neutral and can protect the battery chip from pollution and corrosion. At the same time, the vulcanized silicone rubber has flame retardant properties.
Backplane material
Application: The backplane modified with silicone resin can effectively withstand the test of extreme climatic conditions, such as high temperature, low temperature, strong ultraviolet rays, wind and rain, etc., thereby extending the overall service life of the photovoltaic system, reducing maintenance costs, and improving overall economic benefits.
Surface protection material
Application: Silicone resin can be used to manufacture protective films on the surface of photovoltaic modules to provide weather resistance and wear resistance protection.
Specific products: For example, silicone coatings that use methylphenylsilyl resin as the substrate have excellent heat and weather resistance and are suitable for protective coatings for solar thermal power generation structures.
2. Wind power generation
Blade manufacturing
Application: Silicone resin composite materials are widely used in the manufacture of wind power blades.It has high strength, low weight, and excellent resistance to wind erosion and ultraviolet aging, making it an ideal material for large-scale wind power blades.Through precise molecular design, the perfect integration of resin with reinforced materials such as glass fiber and carbon fiber can be achieved, further improving the overall performance of the blades and reducing the operating costs of wind power equipment.
3. New energy vehicles
Battery package
Application: Silicone resin is used for battery sealing, structural bonding, thermal conductivity and potting to ensure that the battery can maintain stable performance in various harsh environments.With the popularization of CTP (Cell to Pack) battery technology, the application of silicone resin in power batteries is expected to further increase.
Specific advantages: Silicone resin has good thermal conductivity and insulation properties, which can effectively improve the thermal management performance of the battery, while preventing short circuits and leakage inside the battery, and ensuring the safe operation of the battery.
Thermal management
Application: Silicone resin combined with fillers can be used as a thermal interface material (TIM) to prevent overheating of batteries, control units, sensors, and power electronic equipment.
Sealing and bonding
Application: Silicone resins are used in the packaging, sealing and bonding of automotive electronic control units (ECUs) and power supply control units (PCUS) to ensure that these important components are not affected by high temperature, humidity, oxidation and vibration.
Fourth, energy storage devices
Lithium-ion batteries and supercapacitors
Application: Silicone resin is widely used in electrolytes or diaphragm materials for new energy storage devices such as lithium-ion batteries and supercapacitors.By regulating its molecular chain length, crosslinking density and other parameters, the ionic conductivity, thermal stability and chemical stability of the electrolyte can be effectively improved.
Specific advantages: The excellent performance of silicone resin helps to improve the energy density, cycle stability and safety of energy storage devices, and extend the service life of the devices.
V. Hydrogen energy and other renewable energy technologies
Low temperature hydrogen storage
Application: The application of silicone materials in low-temperature hydrogen storage has attracted much attention.By contacting the silicone material with oxygen, it adsorbs hydrogen, and then stores the hydrogen at low temperatures.The adsorption capacity of silicone materials is high, and a large amount of hydrogen can be adsorbed at low pressure, thereby increasing the hydrogen storage density.At the same time, the controllability of the structure and chemical composition of silicone materials can flexibly control and change its ability to adsorb hydrogen and the temperature of desorbed hydrogen.
6. Other applications
Electronic and electrical manufacturing
Application: Silicone resins also have important applications in the field of electronic and electrical manufacturing.For example, it is made into insulating paint, which is used in motors, transformers and other equipment to impregnate the windings to form an insulating protective film to prevent current leakage and ensure the safe and stable operation of the equipment.In addition, silicone resin can also be used as an electronic potting material to fill component gaps in electronic equipment such as integrated circuit boards and LED displays, and to protect, insulate and dissipate heat.
Aerospace and Military industry
Application: Silicone resins are also widely used in the aerospace and military fields.For example, in terms of the protection of aviation engine components, its excellent high temperature resistance, wear resistance and corrosion resistance make it an ideal material for the manufacture of protective coatings; in terms of spacecraft structural materials, its good radiation resistance and high and low temperature resistance can be used in the manufacture of insulation materials, sealing materials, etc.
The application of silicone resins in the energy industry covers many fields such as solar photovoltaic, wind power generation, new energy vehicles, energy storage devices, and hydrogen energy.With its unique performance advantages, silicone resins play an increasingly important role in the energy industry, helping to promote the development of green energy and the optimization of the energy structure.
