以腰果酚为原料合成了一种新型增塑剂环氧化腰果酚磷酸二乙酯(ECEP)。用傅里叶变换红外光谱(FTIR)、氢-1-核磁共振(H-1-核磁共振)和C-13-核磁共振(C-13-核磁共振)对其化学结构进行了表征。研究了ECEP取代石油基增塑剂邻苯二甲酸二辛酯(DOP)在软聚氯乙烯(PVC)薄膜中的作用。用热重分析(TGA)、动态力学分析(DMA)和拉伸试验研究了不同ECEP含量增塑的聚氯乙烯薄膜老化前后的热稳定性和力学性能。结果表明，ECEP增塑的聚氯乙烯薄膜具有较高的热稳定性。当DOP完全取代ECEP时，PVC薄膜的玻璃化转变温度(T-g)从41.07℃降至33.20℃，10%和50%失重温度(T-10和T-50)分别提高了31.57℃和23.09℃。研究了老化前后聚氯乙烯薄膜的力学性能。(C)2016爱思唯尔有限公司。保留所有权利。
A novel plasticizer, epoxidized cardanol diethyl phosphate (ECEP), based on cardanol was synthesized. Chemical structure of ECEP was characterized by fourier transform infrared (FTIR), H-1-nuclear magnetic resonance(H-1 NMR) and C-13-nuclear magnetic resonance(C-13 NMR). Effects of ECEP substitution for the petroleum-based plasticizer dioctyl phthalate (DOP) in soft poly(vinyl chloride) (PVC) films were studied. Thermal stability and mechanical properties before and after aging of PVC films plasticized with different content of ECEP were investigated with thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA) and tensile tests. The results indicated that PVC films plasticized with ECEP showed increased thermal stability. When DOP was substituted for ECEP completely, glass transition temperature (T-g) of PVC films decreased from 41.07 degrees C to 33.20 degrees C, the 10% and 50% weight loss temperatures (T-10 and T-50) increased by 31.57 degrees C and 23.09 degrees C respectively. The mechanical properties of PVC films before and after aging were also investigated. (C) 2016 Elsevier Ltd. All rights reserved.
