Abstract

Mineral–rubber composites based on phosphorylated butadiene rubber (PhBR), including pure expanded perlite (EP) and modified phosphorylated expanded perlite (PhEP) as fillers, are developed. The process involves forming PhBR and its composites—EP/PhBR and PhEP/PhBR—through the oxidative chlorophosphorylation (OxCh) reaction. An in-depth comparative analysis is conducted on the thermal destruction of the PhBR matrix and the EP/PhBR, and PhEP/PhBR composites. The thermogravimetric (TG)/differential thermogravimetry (DTG) analyses reveal three stages of thermal degradation for the PhBR matrix and both composites, highlighting the notable effects of EP and PhEP in the second and third stages of the degradation process. In comparison, the PhEP/PhBR composite exhibits reduced weight loss, the highest integral procedural decomposition temperature (IPDT) value, and a lower T_max on the DTG curve, compared with the EP/PhBR composite and the PhBR matrix. The mechanism of the thermal destruction reaction and the kinetic parameters E_a and A are calculated using the model-fitting Coats–Redfern method.

膨胀珍珠岩改性丁二烯橡胶复合材料的热降解动力学研究

以磷化丁苯橡胶（PhBR）为基础，包括纯膨胀珍珠岩（EP）和改性磷化膨胀珍珠岩（PhEP）作为填料的矿物橡胶复合材料已经研制成功。该工艺包括通过氧化氯磷酸化（OxCh）反应形成 PhBR 及其复合材料--EP/PhBR 和 PhEP/PhBR。对 PhBR 基体、EP/PhBR 和 PhEP/PhBR 复合材料的热破坏进行了深入的比较分析。热重（TG）/差热重（DTG）分析表明，PhBR 基体和两种复合材料的热降解分为三个阶段，其中 EP 和 PhEP 在降解过程的第二和第三阶段具有显著效果。相比之下，与 EP/PhBR 复合材料和 PhBR 基体相比，PhEP/PhBR 复合材料的重量损失更少，程序分解温度积分（IPDT）值最高，DTG 曲线上的 Tmax 更低。采用模型拟合 Coats-Redfern 方法计算了热破坏反应的机理以及动力学参数 Ea 和 A。本文受版权保护。
