Description

一种耐高温起爆药及其制备方法
技术领域
本发明涉及一种耐高温起爆药及其制备方法,属于钝感炸药技术领域。
背景技术
起爆药主要用于起爆非雷管敏感型钝感炸药,近些年来,随着国家采矿业的繁荣,高温作业环境下的起爆需求不断增加,市场对于耐高温起爆药的需求开始涌现。国内起爆药开始于上世纪70年代,最初的起爆药采用数公斤的梯黑火药包作为起爆药,后来,鞍钢与庆阳化工协作开发了以TNT为主装药,用散装太安为药芯,塑料或纸筒为外壳的起爆弹,以TNT为主装药的现代起爆药开始形成。现在市场上销售的起爆药多是以TNT为主装药,TNT学名三硝基甲苯,为白色或黄色针状结晶,熔点为80.35℃,在80℃以上的高温环境下会熔化,无法起爆。
发明内容
本发明的目的是为了解决现有以TNT为主装药的起爆药在高于80℃的高温环境下无法使用的问题,而提供一种耐高温起爆药。
本发明的目的是通过以下技术方案实现的:
本发明的一种耐高温起爆药,所述起爆药中各组分的质量百分比如下:20~40%的硝化棉、20~40%硝化甘油、30~55%黑索金RDX或奥克托今HMX、1~5%的炭黑C、1%~8%的Ⅱ号中定剂。
本发明的一种耐高温起爆药的制备方法,该方法为按照上述起爆药各组分的配比关系将各种原材料经过吸收制造工艺、驱水工艺、压延造粒工艺、压伸成型工艺后得到起爆药药柱成品。
有益效果
本发明的耐高温起爆药可以满足100℃、5h高温环境的使用需求,填补了市场空白。本发明的耐高温起爆药兼具有雷管感度、爆速高、密度大、抗水抗油性好、环保等特点。
具体实施方式
下面结合实施例对本发明的内容作进一步描述。
