Description
技术领域
本发明属于防弹设备技术领域,尤其是涉及一种防多发弹的夹丝防弹玻璃及其制备方法。
背景技术
现有的防弹玻璃是由普通的玻璃层中夹上有机材料层通过热压制得,但是在防多发弹的过程中,会因为普通玻璃的破碎脱落导致厚度逐渐减少,而目前为了更有效的防多发弹,一般会采用增加玻璃厚度及加层数的方法,但是由此会带来玻璃构件总厚度及重量过大的弊端,给安装和使用带来不便。
发明内容
为解决以上问题,本发明提供一种防多发弹的夹丝防弹玻璃及其制备方法,该夹丝防弹玻璃整体的厚度以及重量小,便于安装和使用;且该夹丝防弹玻璃因有夹丝层的存在,在防多发弹的时候,不会因为玻璃抗冲击破碎后而脱落,可以保证玻璃的厚度不变。
为解决上述技术问题,本发明采用的技术方案是:一种防多发弹的夹丝防弹玻璃,包含有三层玻璃原片,所述玻璃原片内部设置有钨丝网。
进一步地,依次包括有玻璃原片、PVB胶片、玻璃原片、PU胶片、玻璃原片和PC板。
进一步地,所述PVB胶片为聚乙烯醇缩丁醛,所述PU胶片为聚氨酯胶膜,所述PC板为聚碳酸酯板。
进一步地,所述夹丝防弹玻璃的总厚度为25-29mm。
一种防多发弹的夹丝防弹玻璃的制备方法,包括以下步骤:
1)将钨丝网进行预热处理;
2)将普通玻璃加热到红热软化状态,之后将步骤1)的钨丝网压入到玻璃中间,形成玻璃原片;
3)将步骤2)中制得的玻璃原片进行裁切,裁切到设计大小,清洗后备用;
4)将PU胶片、PVB胶片和PC板分别裁切到设计大小,清洗后备用;
5)将裁切好的玻璃原片、PU胶片、PVB胶片和PC板,按照玻璃原片+PVB胶片+玻璃原片+PU胶片+玻璃原片+PC板进行层叠合片,形成夹丝防弹玻璃半成品;
6)将步骤5)中的夹丝防弹玻璃半成品进行热压,形成防多发弹的夹丝防弹玻璃。
进一步地,步骤1)中的钨丝网采用的是0.1mm的钨丝。
本发明具有的优点和积极效果是:
1、钨丝的抗拉伸性强,在不影响透光率的条件下,给予夹丝防弹玻璃很好的束缚作用;加入钨丝网的玻璃原片其韧性增加且在受到炮弹的冲击时,不易破碎,可以有效地抗多发弹且玻璃不会破碎脱落;
2、三层玻璃原片,中间通过PVB胶片和PU胶片进行连接,可以增加整个防弹玻璃板的抗弹性能,玻璃原片内设置钨丝网,整个防弹玻璃板的厚度小,重量轻,便于安装与使用。
附图说明
图1为本发明的一种防多发弹的夹丝防弹玻璃的结构图;
图中:1-玻璃原片,2-PVB胶片,3-PU胶片,4-PC板,5-钨丝网。

在本实施例中,进一步地,所述PVB胶片2为聚乙烯醇缩丁醛,所述PU胶片3为聚氨酯胶膜,所述PC板4为聚碳酸酯板。
进一步地,所述夹丝防弹玻璃的总厚度为25-29mm;在本实施例中,所示夹丝防弹玻璃的总厚度为29mm。
一种防多发弹的夹丝防弹玻璃的制备方法,包括以下步骤:
1)将钨丝网进行预热处理,加热到;
2)将普通玻璃加热到红热软化状态,之后将步骤1)的钨丝网压入到玻璃中间,形成玻璃原片1;
3)将步骤2)中制得的玻璃原片1进行裁切,裁切到设计大小,清洗后备用;
4)将PU胶片3、PVB胶片2和PC板4分别裁切到设计大小,清洗后备用;
5)将裁切好的玻璃原片1、PU胶片3、PVB胶片2和PC板4,按照玻璃原片+PVB胶片+玻璃原片+PU胶片+玻璃原片+PC板进行层叠合片,形成夹丝防弹玻璃半成品;
6)将步骤5)中的夹丝防弹玻璃半成品进行热压,形成防多发弹的夹丝防弹玻璃。
在本实施例中,进一步地,步骤1)中的钨丝网5采用的是0.1mm的钨丝。
按照上述制备方法制备得到的夹丝防弹玻璃(作为实施例)与仅采用纯玻璃作为玻璃原片制得的防弹玻璃(作为对比例1)和市售防弹玻璃(作为对比例2)进行抗枪弹性能试验,其检测结果如下表所示:
检测方法:依照GJB59.18-1988《装甲车辆试验规程装甲板抗枪弹性能试验》的检测标准,对实施例、对比例1和对比例2的防弹玻璃进行试验,检测条件为:在常温条件下(室内:温度14℃、湿度47%RH),射距30m,射角0°,用7.62mm弹道枪配53式7.62mm穿甲燃烧弹,有效射弹3发,观察其防弹玻璃的表面状况及其弹痕高度,其具体检测结果如表1所示:
表1抗枪弹性能检测数据
根据表1中所示的实验数据,分析该数据可知,本发明的夹丝防弹玻璃在抵抗三发弹之后,其背面最大弹痕高度为1.5mm,而对比例1和对比例2的最高弹痕接近10mm,且本发明的夹丝防弹玻璃的厚度要小于对比例中防弹玻璃的厚度,故,根据本实验可知,本发明的夹丝防弹玻璃其抗多发弹性能要远远优于现有的防弹玻璃,且本发明的夹丝防弹玻璃,其在受弹后不易破碎。
以上对本发明的一个实施例进行了详细说明,但所述内容仅为本发明的较佳实施例,不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等,均应仍归属于本发明的专利涵盖范围之内。
