摘要：以桐油和3-氨基丙基三乙氧基硅烷(APTES)为原料制备阻燃型桐油基多元醇(PTOA),用PTOA替代常规硬泡聚醚4110制备了一系列聚氨酯硬泡。通过FT-IR和1H-NMR对PTOA进行结构表征,并对聚氨酯硬泡进行热失重分析和其他性能测试,研究了PTOA用量对聚氨酯硬泡性能的影响。结果表明,环氧化桐油酸甘油单酯(EGTO)通过与APTES发生开环反应得到PTOA;随着PTOA替代聚醚4110的量增加,聚氨酯硬泡的初始分解温度降低,第二、三阶段的最大热失重速率温度降低而对应的速率分别减小和增大;泡沫压缩强度先增大后减小,当PTOA替代量为40%时,泡沫的压缩强度可达最高值350 k Pa;当PTOA用量从0到完全替代聚醚4110时,泡沫的极限氧指数由19. 1%提高至23. 0%。
Tung oil-based flame retardant polyol (PTOA) was prepared by tung oil and 3-aminopropyltriethoxy -silane (APTES) as raw materials. A series of rigid polyurethane foams (RPUF) were prepared by PTOA replacing conventional rigid polyether polyol 4110. The PTOA structure was characterized by FT-IR and 1H-NMR. The thermogravimetric analysis (TGA) and other properties test of the foams were conducted. The dosage of PTOA on the properties of rigid polyurethane foams was studied. The results showed that PTOA was synthesized by using epoxidized monoglyceride of tung oil (EGTO) and APTES via the ring opening reaction. When the amounts of PTOA increased, the initial decomposition temperature decreased, the temperature at maximum thermal weightlessness rate T max 2 and T max 3 both decreased while the corresponding weightlessness rates decreased and increased, respectively. The compressive strength of RPUF was increased firstly and then decreased, the compressive strength of RPUF could reach to 350 kPa when the substitution of polyether polyol 4110 by PTOA was 40%. The limited oxygen index was increased from 19.1% to 23.0% when the PTOA substitution of polyether 4110 from 0 to 100%.
