Description

一种新型防弹板及其制备方法
技术领域
本发明专利涉及一种防弹板及其生产制备技术领域,尤其是一种新型防弹板及其制备方法,该防弹板不仅具有与传统防弹板相同的防弹性能,同时具备优良的防水耐老化特性,粘结度强,生产效率高。
背景技术
传统的防弹板基本上都是单纯由防弹材料组成,或者至多在防弹材料外层用黑色涤纶牛津布或涤纶针织布等布料进行涂覆背胶,再通过粘接的方式完成防弹板的外保护层的设置,工艺简单,附加值不高,且以上两种工艺方式生产出来的防弹板还存在如下缺陷:
1)防水耐老化性能差;
2)全手工操作,生产效率低,而且因操作熟练度不同等因素而导致问题产品出现;
3)采用牛津布或者涤纶布与防弹板材粘接需要涂覆胶黏剂,易存在粘接牢度差,开粘的情况。
发明内容
本发明的目的是,提供一种新型防弹板及其制备方法,解决了传统防弹板使用寿命短,生产质量波动大以及生效率低下等不足。
为解决上述技术问题,本发明提供一种新型防弹板,该新型防弹板包括三层结构,由内而外的顺序为:
防弹材料层、外保护层,还包括所述防弹材料层和外保护层之间的界面层;
作为一种举例说明,所述防弹材料层为聚乙烯纤维UD片或芳纶纤维UD片等材料压制而成;
作为一种举例说明,所述外保护层为聚脲涂料、聚氨酯涂料或者聚脲与聚氨酯的混合涂料制作而成;
作为一种举例说明,所述界面层为适合于防弹材料层和外保护层材料的底漆材料制作而成;
作为一种举例说明,所述界面层的厚度为10~15um,此种厚度能保证不增加过多的重量同时,达到最佳的粘结效果和穿着者的舒适度。
作为一种举例说明,所述外保护层的外面为造粒结构表面。
一种新型防弹板的制备方法,包括如下工艺:
压制合膜工艺、裁剪喷砂工艺、干燥打磨工艺以及三次喷涂工艺;
具体的,在实际生产过程中,需根据防护不同的防弹等级选择适当的防弹材料层进行加工制作,作为一种举例说明,
所述“压制合模工艺”包括:将选好的防弹材料层放置于热压机中,合模,工作压强为1mpa,从常温条件下开始升温,逐步升到120℃后,从常压升压至16MPa,保此条件下的温度和压强不变,恒温、恒压30min后,开始降温操作,降温至60℃后出模;
经试验验证,此种温度压强的工艺操作能达到防弹材料的最紧密合模,防弹性能最佳的同时,更适合下面工艺的顺利实施;
所述“裁剪喷砂工艺”包括:压制合模好的防弹材料层进行裁剪修边,并对裁好的防弹材料层进行喷砂处理,并对所述防弹材料层的表面进行喷涂所述界面层操作,控制界面层厚度为10~15um,干燥后对表面进行打磨处理,保证表面平整;
所述“三次喷涂工艺”包括:将处理好的板材进行喷涂外保护层,喷涂设备加热器温度设置为70~80℃,管道加热温度设置为70~80℃,动态工作压力设置为大于13.8MPa,喷涂外保护层分3次进行,第一次喷涂厚度为0.6~0.8mm,第二次喷涂涂层厚度0.6~0.8mm,第三次喷涂涂层厚度控制三次喷涂总厚度2mm±0.2mm,最后对外涂层进行外部造粒或者光面处理。
本发明的有益效果:
1、改善了防弹板材整体的防水及耐老化性能;
2、提高了生产效率;
3、解决因手工操作存在的产品质量不均衡的问题;
4、改善外包材料与纤维防弹板材的粘接牢度
