摘　　要：塑料管材中使用的增塑剂可能会随着时间的推移和使用环境的变化而迁移到水体中,进而影响塑料管材性能,污染水体及周边生态环境,对生态安全造成影响。分析水利工程中塑料管材增塑剂迁移机理可知,影响增塑剂迁移的要素主要包括温度、塑料制品特性、增塑剂含量与分子特性等。为有效抑制水利工程中塑料管材增塑剂迁移,需要通过对塑料管材进行表面处理、接枝改性或加入其他添加剂等方式,提升塑料管材与增塑剂分子间作用力,避免增塑剂向外界环境扩散,保障水质安全。The plasticizers used in plastic pipes may migrate to water bodies over time;with changes in the usage environment,it can affect the performance of plastic pipes,pollute the water and surrounding ecological environment,and affect ecological security.Analyzing the migration mechanism of plasticizers in plastic pipes applied to hydraulic engineering projects,it can be concluded that the factors affecting the migration of plasticizers mainly include temperature,plastic product characteristics,plasticizer content,and molecular characteristics.To effectively suppress the migration of plasticizers in plastic pipes applied to hydraulic engineering projects,it is necessary to enhance the intermolecular interaction force between plastic pipes and plasticizers by surface treatment,grafting modification,or adding other additives.This can prevent plasticizers from spreading to the external environment and ensure water quality safety.
