Preparation of Hydrogen Silicone and Its Application on Addition LED Sealant
Abstract：This article mainly discusses the LED with high transparent silicone sealant in the preparation and properties of hydrogen silicone research, discussed the formula under different solution containing hydrogen silicone oil in the choice of different components, measuring the refractive index and infrared spectrometer detecting the hydrogen silicone oil, the content of the internal structure of benzene is discussed for containing hydrogen silicone oil and silicone oil containing hydrogen and the ratio of vinyl silicone oil after curing film forming properties. And experiment with interaction with vinyl silicone oil containing hydrogen silicone oil after crosslinking curing properties, such as the infrared spectrogram, the DMA determination of glass transition temperature and the shear bond strength after curing film, further discusses the containing hydrogen silicone oil in LED high through the application of silicone sealant, with two different structures containing hydrogen silicone oil. Different formula of film forming of hydrogen silicone curing performance has a decisive role.
