技术领域
本发明涉及一种防弹型防爆门及其制备方法,属于人防工程安全领域。
背景技术
防爆门是具有抵抗一定条件下的爆炸冲击、能够耗散爆炸产生的冲击波压力、吸收破片冲击动能,阻止穿透,有效阻止爆炸危害延续免受爆炸波影响的一种抗爆防护设备。防爆门广泛应用于指挥室、人防工程、炸药库、易燃品仓库、车间、矿井等场所。特别是在人防工程中使用的防爆门,可以有效抗击和阻止爆炸所产生的冲击波,保护人们的生命财产安全。
目前防爆门通常是采用钢筋混凝土或者钢结构制成,这种材质比较坚固耐用。专利CN209384979U公开了一种可解体防爆门,该防爆门包括:钢筋混凝土主门,与钢筋混凝土主门拼接的钢筋混凝土辅助门,用于固定钢筋混凝土主门和钢筋混凝土辅助门并起到加固作用的固定钢板和用于将固定钢板固定至钢筋混凝土主门和钢筋混凝土辅助门的螺栓。在门体结构形式方面,此类钢筋混凝土类防爆门采用较多的结构形式主要为平板式,内部形式采用型钢骨架拼焊(钢梁板)或型钢包边、钢筋绑扎浇注的形式。但是,由钢材和混凝土共同组成的门的面密度大于450kg/m3,十分沉重,使得在安装、使用、维护、保养过程中操作非常困难,钢材锈蚀更是增加了防爆门开闭的难度。此外,传统的防爆门虽能对冲击波能进行有效的防护,但在爆炸过程中往往不只有冲击波,还伴随有高速弹片的产生。对高速弹片侵彻作用的防范机理与对爆轰波的防范机理不同,普通防爆门无法保证对高速弹片有效的防护。
综上所述,需要设计制备一种轻质、耐用、具有防弹功能的防爆门以实现上述目的。

重复步骤S03~步骤S05制得防弹树脂基复合内门板;
步骤S06:由内向外依次贴合防弹树脂基复合内门板、多功能卸爆层、抗爆板和防弹树脂基复合外门板,得到防弹型防爆门。
