Research on Preparation and Application of Low Volatile PA66 Composites
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 2
Abstract
PA66 material has good heat resistance and is widely used in heat-resistant parts of lamps. However, because it is prone to thermo- oxidative decomposition, the small molecular substances decomposed are easy to form fog deposits, which affect the appearance, performance and service life of lamps. Therefore, the study of low-volatile PA66 composites is an urgent issue to be solved. This paper investigated the effects of antioxidants, molecular sieves,PA10T, processing technology and other factors on the volatility of PA66 composites under thermo-oxidative aging, and analyzed the main components of volatiles. It concluded that the copper salt (0.5 wt%) + PA10T (30 wt%) + double vacuum scheme had better fogging, and proved to meet the requirements.
