摘要: 以蓖麻油(CTO)为原料,经环氧化反应制得环氧蓖麻油(ECO),再与甲苯二异氰酸酯(TDI)在80℃和150℃温度条件下进行固化得到2种不同的交联固化材料,并对其分子结构和各项性能进行详细分析。结果表明:制备的2种固化材料,其拉伸强度、硬度和玻璃化转变温度均有明显提高;热重分析显示2种固化材料均具有良好的热稳定性,热初始分解温度均在280℃左右。高温150℃固化得到的材料中含有典型的氨基甲酸酯-噁唑烷酮双重固化交联结构。

Abstract: Epoxidized castor oil (ECO) was synthesized via epoxidation of castor oil (CTO). Then the prepared ECO was cured with toluene diisocynate (TDI) at 80℃ or 150℃ to obtain two kinds of cured cross-linking materials, and their molecular structures and comprehensive properties were studied. The results showed that the tensile strength, hardness and glass transition temperature of these two cured materials were improved significantly. Thermogravimetric analysis showed that all cured materials owned good thermal stability and the heating initial decomposition temperatures of cured materials were above 280℃. And the cured material obtained at 150℃ possessed typical carbamic-oxazolidone double cross-linking molecular structure.

Key words: castor oil, epoxidized castor oil, double cross-linking, carbamic-oxazolidone, comprehensive properties
