Description

碳纳米管聚集体于制备纳米碳抗冲击材料中的用途及其制备方法 技术领域
本申请涉及一种抗冲击材料，特别涉及一种碳纳米管聚集体于制备防爆材料、防弹材料、防刺材料等纳米碳抗冲击材料中的用途与其制备方法。
背景技术
抗冲击材料，包括防爆、防刺、防弹材料等在武器、化工、交通、航天等领域均得到了广泛的应用。传统的抗冲击材料主要有金属材料、高分子材料、陶瓷材料等。其中的金属材料、陶瓷材料虽然通过形状和结构设计，可以产生良好的抗冲击性能，但是结构笨重，且均是刚性的，在使用时会严重影响个体运动的灵活性。而基于高分子材料的抗冲击材料主要由超高分子量聚乙烯纤维、聚酰胺类纤维和PBO类纤维等制成。此类抗冲击材料虽然相比于金属、陶瓷等刚性抗冲击材料具有质量轻等优点，然而仍存在较多不足，例如：超高分子量聚乙烯纤维不耐热，最高耐受温度低于120℃；聚酰胺类纤维不耐紫外光和水气；这些高分子材料的密度仍然相对较高。因而，这些材料难以适应某些领域的应用需求。例如，当作为个体防护材料时，这些高分子抗冲击材料形成的防护结构厚重，穿着舒适性差，不透气，影响人体活动和灵活性。
鉴于传统抗冲击材料的不足，研究人员还提出了多种改进方案。例如，CN101218480B公开了一种由高韧性纤维的网形成的织物基体，通过在该基体上一次粘附粘结层和橡胶层，多个这样的单元堆叠形成柔性的防刺复合材料，材料结构复杂，加工性能差，不适合批量化制备。又如，US2004/0048536A1通过在高性能纤维织物表面粘附一定量的固体硬质颗粒物质，可以钝化刀具侵彻深度。US20070105471中通过将无机颗粒涂覆于芳纶织物表面以改善材料的防刺性能，但其结构变硬，使得穿着舒适性下降。又如，CN102058188B通过将纳米粒子与高性能纤维织物复合后再与热塑性树脂复合，可以大幅提升抗冲击性能，并有效减少重量减少，以及使材料本身的柔软度基本无变化。再如，CN100567606A通过将碳纳米管溶于胶黏剂中再涂覆于UHMWPE纤维上，可有效地提高UHMWPE的耐热性和蠕变性及机械强度等。但由于纳米材料制备技术的不成熟，前述方案中只能通过表面在胶黏剂中添加少量的纳米材料来提高防弹性能，纳米材料在胶黏剂中分散的均匀性以及在高性能纤维表面的堆积形态和分布情况都影响到材料的防弹性，但这些因素均难以调控。而且由此形成的防弹材料仍然是硬挺的，密度大、质量重，与人体贴合性差，穿着舒适性差，对于人体运动的灵活性仍有严重影响。
发明内容
