聚四氟乙烯微粉改性激光全息成像树脂的研究

Study of Laser Holographic Imaging Resin Modified with PTFE

将聚四氟乙烯微粉（PTFE）分散于醋酸丁酯中,取配方量的分散液对激光全息成像树脂进行共混改性。通过旋转黏度计、漆膜冲击强度测试仪、模压机研究了PTFE的加入及其加入量对树脂黏度、冲击强度以及模压效果等方面的影响。结果表明：在PTFE加入量为成像树脂质量的1%~1.5%时,激光全息成像树脂的综合性能最好。

Dispersed polytetrafluoroethylene micro-powder into the butyl acetate the formula quantity of disper sed liquid was modified with the laser holographic imaging resin.The influences of the adding of PTFE and its add quantity on the viscosity,the impact strength and moulding behavior of the resin were studied by rotating viscometer,film impact strength tester and moulding machine respectively.The results showed that the laser holographic imaging resin were of the best comprehensive performance when the add quantity of PTFE was 1%~1.5%.
