Description

一种具有电磁屏蔽功能的复合防爆门
技术领域
本发明涉及一种具有电磁屏蔽功能的复合防爆门，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和破片，保护人们的生命财产安全。
电磁波辐射，又称电磁辐射，是由同相振荡且互相垂直的电场与磁场在空间中以波的形式传递能量和动量，其传播方向垂直于电场与磁场构成的平面。长期暴露在某些对人体有害频段电磁波环境中，会引起头晕目眩记忆力减退耳鸣等现象，有些会破坏免疫系统，增加致癌的机率如一次性较高剂量的远紫外和X射线，有些短时间内完全暴露可直接致死，如伽马射线。专利CN211598258U公开了一种新型用于保证人体安全的高防辐射型人防门，该人防门通过在门体外部均匀涂覆电磁屏蔽层来实现电磁屏蔽的功能。然而通过此种方法得到的电磁屏蔽涂层在使用过程中容易脱落，无法满足使用需求。专利CN109538080A公开了一种高强度人防门，该人防门门体由外至内依次为耐腐蚀涂层、外铅板、电磁屏蔽层、发泡塑料层、第一铜丝网层、钢筋混凝土层、第二铜丝网层以及内铅板，所述电磁屏蔽层的原料组成为：丙烯酸改性有机硅树脂、水性聚氨酯树脂、环氧树脂、导电聚苯胺、化学镀银碳纤维、镍粉、炭黑、铜粉、有机膨润土、聚醚改性有机硅、乙酸乙酯、丙三醇、羧甲基纤维素钠、聚乙烯醇、分散剂。可以看出，通过该方法制备的电磁屏蔽层所需原料较多，制备工艺较为复杂。因此需要开发一种制备工艺简单，且持久耐用的电磁屏蔽型复合防爆门。
发明内容
本发明的目的在于，提供一种制备工艺简单，且持久耐用的电磁屏蔽型复合防爆门。
为解决上述技术问题，本发明采用如下的技术方案：一种具有电磁屏蔽功能的复合防爆门，包括由外向内依次设置的电磁屏蔽改性树脂基复合外门板、轻质防破片夹层、卸爆层和电磁屏蔽改性树脂基复合内门板；所述电磁屏蔽改性树脂基复合外门板和电磁屏蔽改性树脂基复合内门板均包括电磁屏蔽复合防爆内芯和电磁屏蔽涂层；所述电磁屏蔽复合防爆内芯由块状模塑料与多层复合铜网模压制而成。
前述的这种具有电磁屏蔽功能的复合防爆门中，所述电磁屏蔽复合防爆内芯的制备方法为：步骤S01：在第一模具底部铺设三层黄铜丝布，随后称取20～25kg块状模塑料置于第一模具内进行首次压制，得到复合内芯A；首次压制时上模温度为145～185℃，下模温度为140～180℃，成型压力为5～15MPa，成型时间为15～20min；
步骤S02：在复合内芯A顶部涂上一层电磁屏蔽涂层，随后将涂有电磁屏蔽涂层的复合内芯A置于第二模具内，并在转移置第二模具内的复合内芯A的顶部铺设三层黄铜丝布，随后再称取15～20kg块状模塑料置于第二模具内进行二次压制，得到电磁屏蔽复合防爆内芯；二次压制时上模温度为155～195℃，下模温度为60～100℃，成型压力为10～20MPa，成型时间为10～15min；
所述黄铜丝布的网孔目数为100～200目；所述块状模塑料以质量份数计，由70～90份间苯二甲酸聚酯树脂、50～100份短切玻璃纤维、100～120份填料以及5～10份添加剂充分搅拌混合而成；所述填料为碳酸钙、碳酸镁、氢氧化镁、氢氧化铝、硬脂酸锌中的一种或几种；所述添加剂为苯乙烯、过氧化碳酸-2-乙基已酸叔丁酯、聚乙酸乙烯酯中的一种或几种。
前述的这种具有电磁屏蔽功能的复合防爆门中，所述电磁屏蔽涂层为铜系涂层、银系涂层、镍系涂层中的一种，电磁屏蔽涂层的厚度为50～100μm。
前述的这种具有电磁屏蔽功能的复合防爆门中，所述轻质防破片夹层由4～8层防破片布料粘结压合而成。
前述的这种具有电磁屏蔽功能的复合防爆门中，所述防破片布料的制备方法为：步骤S1：以硼纤维为芯线，将膨体聚四氟乙烯纤维和凯夫拉纤维以5°～15°的螺旋夹角同时包覆在硼纤维表面制备成包缠线；步骤S2：以碳纤维为芯线，将超高分子量聚乙烯纤维以5°～15°的螺旋夹角螺旋包覆在芯线表面，随后将聚乙烯醇纤维以50°～70°的螺旋夹角包覆在最外层制成三层包芯线；步骤S3：以上述包缠线为经线，三层包芯线为纬线，按照“三下一上”织法织成经纬密度为(120～145)×(70～90)的斜纹布，此斜纹布为所述防破片布料。
前述的这种具有电磁屏蔽功能的复合防爆门中，所述卸爆层由直径均匀的空心玻璃微球和剪切增稠液体组成，所述空心玻璃微球的粒径在600～1000μm之间。
与现有技术相比，本发明具有电磁屏蔽功能的复合防爆门，制备工艺简单，原料易得，制备过程中废弃物排放较少，适合工厂大规模生产；通过在电磁屏蔽改性树脂基复合外门板和电磁屏蔽改性树脂基复合内门板中设置本发明方法所制得的电磁屏蔽复合防爆内芯，使得本发明复合防爆门具有优异的电磁屏蔽效果，使用过程中电磁屏蔽涂层不易脱落，使用寿命较长；通过采用由防破片布料制成的轻质防破片夹层，使得本发明复合防爆门质量较轻，但具有较强的耐冲击性能，而卸爆层能够保证本发明复合防爆门可以有效阻止高速破片对门体的侵彻作用。
