Description

高强度索具及其制备方法
技术领域
本发明涉及一种高分子材料应用领域,尤其涉及一种高强度索具及其 制备方法。
背景技术
超高分子量聚乙烯 ( Ul tra High Molecular Weight Polyethylene, 简称 UHMW-PE )是一种线型结构的具有优异综合性能的热塑性工程塑料, 以这种材料为基础制成高强纤维是其最重要用途之一。
超高分子量聚乙烯(UHMW-PE )纤维是一种高性能纤维, 具有强度高、 耐磨、 耐冲击、 耐腐蚀、 耐紫外等优点, 广泛应用于制备吊装绳、 缆绳、 负力绳索、 重载绳索、 救捞绳、 拖拽绳、 帆船索、 钓鱼线、 海洋操作平台 固定锚绳等各类索具。基于超高分子量聚乙烯纤维制备的索具,在自重下 的断裂长度约是钢丝绳具的 8倍, 约是芳纶绳具的 2倍,其具有的优异的 性能。
基于超高分子量聚乙烯纤维的绳索通常是将 N根超高分子量聚乙烯纤 维加捻、 编织或通过外套束紧而成。 由于超高分子量聚乙烯纤维为丝状结 构(单丝纤度 2. 5旦左右), 因此在基于超高分子量聚乙烯纤维制备各类索 具的过程中, 需要对多根丝状结构的纤维进行分别整理, 工艺复杂, 成本 高,且在产品制备过程中, 纤维表面受摩擦易产生毛刺, 纤维易发生断丝、 扭曲、 缠绕等现象, 不利于多根纤维的整体均匀受力, 导致制得的索具的 整体强度往往低于 N根超高分子量聚乙烯纤维的强度之和, 强度利用率较 低。

超高分子量聚乙烯是分子量 100万以上的聚乙烯。超高分子量聚乙烯 应用的传统技术是以超高分子聚乙烯纤维为基础制备各类产品。本发明各 实施例提供的技术方案,与超高分子量聚乙烯应用的传统技术有着本质的 不同, 是对传统技术提出的革命性创新, 其核心思想主要包括: 将超高分 子量聚乙烯薄膜或条带,替代传统的超高分子量聚乙烯纤维,来制备各类 索具。
其中, 如图 1所示,超高分子量聚乙烯薄膜是一种由超高分子量聚乙 烯制成的、 具有一定宽度和厚度的薄片, 且宽度远远大于厚度。 如图 2 所示,条带可独立制备或可由该薄膜拉伸前后进行分切工序形成的条状薄 片, 条带的宽度小于薄膜的宽度, 厚度与薄膜相当或大于薄膜的厚度。
本发明提供的超高分子量聚乙烯薄膜或条带,与超高分子量聚乙烯纤 维不同, 与由多根超高分子量聚乙烯纤维胶接形成的平面也不同, 它们的 显著区别在于:本发明提供的超高分子量聚乙烯薄膜或条带本身具有一定 的宽度和厚度, 是一种没有结合点或裁切线的整体结构。
本发明各实施例提供的高强度索具的本体是基于超高分子量聚乙烯 薄膜或条带制得。在所述本体的制备过程中,是将超高分子量聚乙烯薄膜 或条带作为一个整体进行处理, 结构整体性好、 制备工艺简单, 省去了对 多根纤维丝进行分别整理的复杂工艺,明显降低了薄膜或条带的表面产生 毛刺的概率, 也明显降低薄膜或条带内部出现断丝、扭曲、缠绕等现象的 概率。在包括该本体的索具承载荷载时,超高分子量聚乙烯薄膜或条带是 整体受力, 使得该索具的强度较高, 有效提高强度利用率。 因此, 基于超 高分子量聚乙烯薄膜或条带制备的索具的强度,高于采用相同旦数的超高 分子量聚乙烯纤维制备的产品,且前者的成本明显低于后者,具有结构整 体性好、 强度高、 强度利用率高、 生产效率高、 加工成本低、 重量轻、 面 密度小、 柔性好等优点。
