主 题:Coatings Temperature-resistant HGM/PPENK Thermal conductivity Mechanical properties
摘 要:Novel high temperature-resistant coatings with high mechanical strength and thermal-insulating performance were prepared with poly(ether nitrile ketone)(PPENK)resin as matrix and hollow glass microspheres(HGMs)as thermal-insulating *** corresponding mechanical and thermal-insulating study indicated that the mechanical properties of the coatings decreased with the increase of HGM content,and were improved after surface modification of HGM by KH570 resulting in enhancement of interaction between HGM and PPENK *** thermal conductivity of HGM/PPENK thermal-insulating coating decreased with the increase of HGM content and coating thickness,along with the decrease of the true *** also showed slight increase trend due to HGMs surface *** HGM/PPENK coating filled with modified HGMs showed better thermal resistance than that of unmodified HGM/PPENK *** thermal decomposition temperature at 5%weight loss of the coating containing modified HGMs was 10°C lower than that of pure PPENK,and 40°C higher than that of neat HGM/PPENK *** coating exhibited commendable appearance after 400°C for 30 *** merits of HGM/PPENK-based thermal coatings obviously demonstrated promising prospect in thermal protection fields.
