摘要：
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-CH=CH 2 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. © 2018, Editorial Department of Journal of Building Materials.
