Description

一种防刺复合材料及其制备方法
技术领域
本发明属于防护材料领域。具体地，本发明涉及一种防刺复合材料及其制备方法。
背景技术
在人体防护领域，除防弹要求外，还需要对各种刀具具有防护功能，因此需要使用对各种刀具具有有效防护功能的材料设计防护服。
对刀具具有有效防护功能的材料有金属板包括钢板、铝板、钛合金板等金属合金板等。
CN2625838公开了一种防刺服，防刺层由数块四周边缘带有连接钩的金属两两相互搭嵌拼接构成，各块金属片之间不留缝隙。由于各块金属片边缘有连接钩，所以互相搭嵌而不留缝隙，有效地克服了刀刃滑入缝隙处给防护人带来的伤害，具有良好的防护效果。但是这种防刺服存在重量过重，灵活性差，穿着不舒服，不容易折叠保存等缺点。
由于非金属复合材料质量轻，随形性好，穿着舒适，是各防护单位争相研发的防刺复合材料。超高分子量聚乙烯纤维是目前最适合于制作防刺服的纤维之一，具有密度低、强度高、模量高等优良性能，作为高性能纤维，超高分子量聚乙烯纤维的断裂伸长率较低，具有较好的耐疲劳性和耐摩擦性，由于聚乙烯的分子结构中不含有氨基、羟基等具有较好活性的基团，分子的结晶度高，所以纤维不论在水中或者其它腐蚀性介质中性能都叫稳定，密度小质量轻且能量吸收性好。
目前，单层材料无法满足基本的防刺要求，一般采用多层复合方法制备防刺材料。现有的许多防刺复合材料使用超高分子量聚乙烯(UHMWPE)织物或聚乙烯织物/钢板，当满足24J防刺要求时，其厚度非常厚，由这种结构制备的防刺服非常不方便且随形性差。
因此，本领域中对可用于制备薄而轻的防刺服的防刺材料存在需求。
发明内容
本发明的一个目的是提供可用于制备薄而轻的防刺服的防刺材料。
根据本发明的第一方面，提供一种防刺复合材料，其为通过水性粘合剂体系粘合的多层聚烯烃无纺织物的层合体，所述聚烯烃无纺织物是由无序排列的短纤维经无纺织物制造工艺加工而成的织物。
根据本发明的第二方面，提供制备上述防刺复合材料的方法，其包括以下步骤：
提供多层独立的聚烯烃无纺织物和水性粘合剂体系；
用水性粘合剂体系浸渍所述聚烯烃无纺织物以获得多层浸渍有水性粘合剂体系的聚烯烃无纺织物；
干燥所述浸渍有水性粘合剂体系的聚烯烃无纺织物并将多层干燥后的聚烯烃无纺织物层压在一起形成层合体。
根据本发明的第三方面，提供一种防刺制品，其采用上述防刺复合材料制备而成。
在满足GA 68-2008-24J防刺测试要求的前提下，与现有技术的防刺服相比，采用本发明的防刺复合材料制备的防刺服可以更薄而轻。
