Abstract:

Nylon 66(PA66),as an important engineering plastic,features excellent mechanical properties,wear resistance and heat resistance,and is widely used in the automotive,electronic,mechanical and aerospace fields.However,its inherent high hygroscopicity,poor low-temperature toughness,insufficient processing fluidity and inadequate flame retardancy limit its application in some high-performance scenarios.In recent years,significant progress has been made in the modification research of PA66.Mainly through various means such as physical blending,chemical grafting, and copolymerization modification,its microstructure and macroscopic properties are regulated,thereby preparing composite materials with high strength,high toughness, low water absorption rate,excellent flame retardancy or thermal conductivity.This article introduces the research progress of various high-performance PA66 composites in recent years,analyzes the influence of various modification strategies on the structure and performance of the materials,and the preparation of various high-performance PA66 composites has expanded the application scope of PA66,which is more conducive to its development in high-performance and functional industries such as new energy and automobiles.

Key words: Nylon 66, High strength, Low water absorption, Flame retardancy, Thermal conductivity

摘要:

尼龙66(PA66)作为一种重要的工程塑料,具有优异的力学性能、耐磨性和耐热性,在汽车、电子、机械及航空航天等领域应用广泛。然而,其固有的吸湿性高、低温韧性差、加工流动性不足以及阻燃性限制了在某些高性能场景中的应用。近年来,PA66的改性研究取得了显著进展,主要通过物理共混、化学接枝、共聚改性等多种手段调控其微观结构与宏观性能,从而制备出具有高强度、高韧性、低吸水率、优良的阻燃性或导热功能化的复合材料。介绍了近年来各种高性能的PA66复合材料的研究进展,分析了各类改性策略对材料结构与性能的影响;各种高性能的PA66复合材料的制备,扩展了PA66的应用范围,有利于其在新能源、汽车等高性能、功能化产业中的应用。
