摘要:以氢化松香(HR)、八甲基环四硅氧烷(D4)、四甲基四乙烯基环四硅氧烷(D4Vi)、γ-氨丙基甲基二乙氧基硅烷的水解物(HAPMS)和六甲基二硅氧烷(MM)为原料,合成了氢化松香改性的乙烯基聚硅氧烷(HR-VMS),并利用1H NMR、13C NMR和FT-IR对其结构进行了表征。利用差式扫描量热法(DSC)研究了在2,5-二甲基-2,5-双(叔丁基过氧基)己烷(DBPH)存在下HR-VMS树脂的固化行为和树脂固化物的耐低温性能,并利用热失重分析(TG)研究了HR-VMS树脂固化物的热分解行为。最终数据显示,升温速率为10℃/min时,HR-VMS在186.9℃出现聚合放热峰极值,ΔH为100.3 J/g;HR-VMS树脂固化物的耐高温热稳定性得到显著的提高,最大热失重发生于436.1℃,比乙烯基聚硅氧烷树脂固化物提高了68℃。
Hydrogenated rosin (HR) modified vinyl polysiloxane (HR-VMS) was firstly synthesized from HR, hexamethyldisiloxane ( MM ), 1,3,5,7-tetravinyl-1,3,5,7-tetramethylcyclotetrasiloxane ( D4 Wi ) , octamethyl eyelotetrasiloxane ( D4 ) and hydrolyzate of T-aminopropyl (diethoxy) methylsilane (HAPMS). The novel resin (HR-VMS) was further characterized by 1H NMR, 13C NMR and FT-IR. The curing behavior of HR-VMS with 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane (DBPH) as the curing agent was studied by differential scanning calorimetry (DSC). The low-temperature resistance and high-temperature thermal stability of the curing product were studied by DSC and TG, respectively. The results showed that at the heating rate of 10℃/min, the peak-top temperature of exothermic peak for HR-VMS was 186.9 ℃ with the exothermie value of 100.3 J/g. The curing product from HR-VMS showed better high-temperature thermal stability compared with VMS, and the temperature corresponding to its maximum weight loss rate was 436.1 ℃ which was 68℃ higher than that of common vinyl polysiloxane resin.
