Abstract

Abstract

The surface tension of binder containing different additives and the contact angle with RDX were measured by a contact angle meter. The coating quality is evaluated according to the micro-images acquired by scanning electron microscopy (SEM), the spectrum by X-ray photoelectron spectroscopy (XPS) and the impact sensitivity of the samples. The spreading coefficient (S) and adhesive work (W₁₂) were calculated, and then the dependence of the coverage degree (R) on S and W₁₂ were analyzed. The results show that R increased with the increase of S, and reduced with the increase of W₁₂. It indicates that the better coating quality comes with the bigger S and the smaller W₁₂. And the lower mechanical sensitivity comes with the greater coverge degree. The results of SEM show that a thin layer of film was formed on the surface of RDX. The results of XPS show that the additives can raise the coverage degree from 16.85% to 95.41%. The results of impact sensitivity show that the additives can raise the characteristic fall distance from 11.47 cm to 25.12 cm, and significantly reduce friction sensitivity.
