摘要: 用硅烷偶联剂Si69和KH550对脱硫灰进行化学改性,用改性脱硫灰取代部分炭黑与丁苯橡胶复合,制备环保型丁苯橡胶,对其进行了表征,采用均匀设计结合BP神经网络建立模型优化工艺参数. 结果表明,最优制备工艺参数为Si69和KH550用量分别为4.3wt%和3.8wt%、无水乙醇用量22.1wt%、搅拌速度705 r/min、反应温度82℃,该条件下所制环保型丁苯橡胶的力学性能为拉伸强度19.64 MPa、撕裂强度44.96 kN/m、邵氏A硬度66. 实验结果与模型预测值吻合较好,相对误差为3.03%~2.65%.

Abstract: Desulfurization ash was chemical modified by silane coupling agents Si69 and KH550, then environmentally friendly styrene butadiene rubber was prepared using chemical modified desulfurization ash replacing partial carbon black. The optimization model was established by uniform design combination with BP neural network to acquire parameter of optimal environmentally friendly styrene butadiene rubber. Optimal environmentally friendly styrene butadiene rubber was characterized. The results showed that the preparation parameters of optimal environmentally friendly styrene butadiene rubber were contents of silane coupling agents Si69 4.3wt% and KH550 3.8wt%, content of absolute ethyl alcohol 22.1wt%, stirring speed 705 r/min and reaction temperature 82℃. The mechanical properties of optimal environmentally friendly styrene butadiene rubber were tensile strength 19.64 MPa, tear strength 44.96 kN/m and Shore A hardness 66. The experimental results were good agreement with the predict results, relative error was 3.03%?2.65%.
