第二十二讲 聚合物粘接炸药中的聚氨酯粘合剂系统

聚合物粘接炸药（PBX）是用聚合物粘合剂将炸药颗粒粘接成一体的炸药。当今，在PBX中最常用的粘合剂系统是聚氨酯基粘合剂，同时，为了便于制造或调节力学性能和化学稳定性，粘合剂系统中还要加入增塑剂和其它助剂。本文介绍了PBX用粘合剂的发展历史、聚氨酯粘合剂系统的组分及其性能、配方设计、试验和质量控制的基本内容，特别介绍了澳大利亚国防科技组织（DSTO）所进行的工作。

Lesson 22 Polyurethane Adhesive System in PBX

A polymer-bonded explosive, also called PBX or plastic-bonded explosive, is an explosive material in which explosive powder is bound together in a matrix using small quantities (typically 5-10% by weight) of a synthetic polymer ("plastic"). The most common used adhesive system in PBX is polyurethane adhesive system. Meanwhile, for the convenience of manufacturing and regulating mechanical properties and chemical durability, plasticizer and other addition agents are added to the adhesive system. This article...
