摘要

近年来，聚合物粘结炸药（PBX）已被广泛应用于各种军事应用中。许多不同种类的聚合物被用于这种爆炸制剂。该组件决定了PBX的制备方法和性能。本文介绍了以四硝酸季戊四醇酯（PETN，penthrite）和硅橡胶为基础的炸药组合物的制备和测试研究结果。进行这些研究是为了获得PBX的弹性配方。因此，检查了应用硅橡胶作为组合物的组分的可能性。在本研究的第一阶段，制备了几种组合物，以选择与炸药内聚力有关的最佳混合比。为此，开发了一种使用Brookfield纹理分析仪的新方法。随后，使用热分析方法进行了兼容性测试。对最佳配方进行了物理化学和爆炸性能测试。

A New Testing Method for the Mechanical Properties of Elastic Explosive Compositions

In recent years, Polymer Bonded Explosives (PBX) have been used in a wide variety of military applications. Many different kinds of polymers are used for such explosive formulations. This component determines both the preparation method and the properties of a PBX. In this paper, results are presented of studies on the preparation and testing of explosive compositions based on pentaerythritol tetranitrate (PETN, penthrite) and silicone rubber. These studies were undertaken to obtain elastic formulations of PBXs. Therefore, the possibility of applying a silicone rubber as a component of the composition was checked. In the first stage of this study, several compositions were prepared in order to choose the optimal mixture ratio with respect to cohesion of the explosive. For this purpose, a new method using the Brookfield Texture Analyser was developed. Subsequently, compatibility tests using thermal analysis methods were carried out. The best of composition was subjected to tests for determining its physicochemical and explosive characteristics.
