介绍了123树脂的组成及固化机理,重点介绍了123树脂的合成、精制及改性,其中催化剂的选择不仅影响催化活性和反应速度,还能直接影响预聚物的黏度,进而影响固化产物的性质。此外,还介绍了123树脂在推进剂和炸药中的应用情况。
The composition and curing mechanism of 123 resin were introduced. The synthesis, purification and modification of 123 resin were introduced. The choice of catalyst not only affected the catalytic activity and reaction rate, but also directly affected the viscosity of prepolymer, nature. In addition, the application of 123 resin in propellants and explosives is introduced.
