摘要: 聚碳酸酯(PC)是一种广泛应用于电子、汽车、医疗、建筑等领域的重要工业塑料,然而其生产过程中的环境问题备受关注。本研究采用生命周期评价方法,对工业应用最多的界面缩聚法制备PC生产过程中的环境问题进行了评估,并提出了改进建议。研究发现,海洋水生毒性潜能是主要的环境影响类型,其占总环境影响的84.86%;双酚盐预制工序是产生环境影响最大的阶段,其对总环境影响的贡献为58.29%。此外,原料氢氧化钠的使用对臭氧层破坏潜能的贡献最大,生产过程的电耗则对陆地生态毒性潜能的贡献最大,而双酚A和光气对臭氧层破坏和陆地生态毒性潜能以外的环境指标产生了较大影响。根据研究结果,提出了包括提高原料利用率、改进原料生产工艺、降低生产过程的能耗等改进方法,可以有效地降低PC生产过程对环境的影响,并提高生产效率和经济效益。本研究对PC生产过程的改进和优化提供了有益的参考,有助于实现可持续发展目标,保护环境和人类健康。

Abstract: Polycarbonate (PC) is an important industrial plastic widely used in fields such as electronics, automotive, medical, and construction. However, environmental issues during its production process have received much attention. This study used the life cycle assessment method to evaluate the environmental issues in the production process of PC using the most widely used interfacial polymerization method and proposed improvement suggestions. The study found that the main environmental impact type was the marine aquatic ecotoxicity potential, accounting for 84.86% of the total environmental impact. The prepolymerization stage of bisphenol A was the stage that generated the greatest environmental impact, contributing 58.29% of the total environmental impact. In addition, the use of raw material sodium hydroxide contributed the most to the ozone depletion potential, while the electricity consumption during the production process contributed the most to the terrestrial ecotoxicity potential. Bisphenol A and phosgene had a significant impact on environmental indicators beyond the ozone depletion and terrestrial ecotoxicity potential. Based on the research results, improvement methods were proposed, including improving raw material utilization, improving raw material production processes, and reducing energy consumption in the production process, which can effectively reduce the environmental impact of PC production and improve production efficiency and economic benefits. This study provides useful reference for the improvement and optimization of PC production process, which helps achieve sustainable development goals and protect the environment and human health.
