摘要: 传统线性低密度聚乙烯树脂制备过程中有粘壁形成结片、堵塞出料系统等问题,不利于装置稳定运行。为此研究线性低密度聚乙烯树脂制备及制备成品性能。通过控制吹气频次、反应温度、熔融指数和在反应器内部加膜,解决制备过程中结片及堵塞问题,实现制备装置的长周期稳定运行。实验结果表明,制备的线性低密度聚乙烯树脂具有良好的耐环境应力开裂性及断裂强度,力学性能综合表现较好。

Abstract: In the preparation process of the traditional linear low-density polyethylene resin, there are problems such as sticking of the wall and blocking the discharge system, which is not conducive to stable operation of the device. To this end, linear low-density polyethylene resin was prepared to prepare and prepare finished products. By controlling the blowing frequency, reac-tion temperature, melt index and adding film inside the reactor, the problem of sheeting and clogging during the preparation process is solved, and the long-term stable operation of the preparation device is realized. The experimental results show that the prepared linear low-density polyethylene resin has
good environmental stress crack resistance and fracture strength, and the mechanical prop-erties are better.
