本文阐述了用于提高建筑结构抗爆炸冲击的常规措施方法,分析了在防护上所存在的缺陷。同时,介绍了聚脲作为高聚物弹性体对防护结构具有较好的抗爆耐冲击防护效果,并且能够有效提高抗冲击性能和能量吸收的机理。聚脲材料可与不同纤维及其制品组成高强度、高弹性模量和可吸收爆炸冲击能量的复合材料,在防护结构抗爆炸毁伤领域具有可观前景,并展望了未来研究方向,以实现自主研发具有抗爆耐冲击的聚脲基体复合材料。

This paper expounded the conventional measures to improve the anti-knock and impact of building structures and analyzed the defects in the protection.Polyurea as a high polymer elastomer had good impact resistance effect on the protective structure,the research status of the mechanism of improving the impact resistance and energy absorption was introduced.It could be combined with fiber to form a composite material with high strength,high elastic modulus and absorbable blast impact energy.It had a considerable prospect in the field of anti-explosion damage of protective structure.The future research direction was prospected in order to realize the independent research and development of polyurea matrix composites with anti-knock and shock resistance.
