Inhibitor performance and the preparation study of urea formaldehyde resin matrix composite particle

摘要

In order to improve the service life of weapons, an erosion additives of urea formaldehyde (UF) resin matrix composite particle is prepared by using in-situ polymerization method. The morphology composite particle is represented through scanning electron microscope, and the thermal analysis method is utilized to determine the organic and inorganic components proportion of erosion inhibitors. Finally, a contrasting ablation tube test is made to test its inhibitor performance. The experimental results show that the prepared inhibitor has a good particle dispersion and uniformity. The allocation ratio of organic and inorganic components is about 5.38:1. Compared to erosion inhibitor efficiency of standard propellant, that of the prepared erosion inhibitor can reach 17.56%. The application of this type of erosion inhibitor can decrease the ablative properties of the propellant, which is expected to reduce the erosion problems of high energy propellant.
