Highly transparent silicone resin with self crosslinking structure was prepared using phenyltrimethoxysilane, diphenyldimethoxysilane, 1,3,5,7 cyclotetra(methyl siloxane) and bisvinyltetramethyldisiloxane as main raw materials. The effects of different molar ratios of Si—H/Si—CHCH2 on the reaction of silicone resins and the properties of cured products were investigated. The curing process was investigated by differential scanning calorimetry(DSC). The light transmittance was measured by UV Vis spectroscopy. Thermogravimetric analysis(TGA) was used to study the thermal decomposition process. The results show that the self crosslinking silicone resin has a smaller and a slower exothermic peak. The cured self crosslinking silicone resin has better light transmittance up to 100% in the range of 400800nm. The cured product has relatively good heat resistance, the initial thermal decomposition temperature of the cured product could be up to 3158℃. The self crosslinking silicone has higher transparency compared with the existing condensation silicone material,and can be used as advanced architectural translucent materials and optical packaging materials.
