Abstract

芳纶粉末复合注塑履带芯金及其生产工艺，包括芳纶骨架和壳体，壳体为超高分子量聚乙烯材质外壳，超高分子量聚乙烯材质外壳包覆在芳纶骨架表面，首先将芳纶粉末经涂胶和除静电工艺处理后，再经过高温高压压制形成芳纶骨架，然后将超高分子量聚乙烯包覆在芳纶骨架表面，使超高分子量聚乙烯与内部芳纶粉末融为一体。本发明将芳纶材料作为骨架材料用于履带芯金中，大大提高了履带芯金的强度和使用寿命，经检测本发明的履带芯金相对于普通的履带芯金，强度提高了2倍，寿命提高了3倍。

Description

芳纶粉末复合注塑履带芯金及其生产工艺
技术领域
本发明涉及高分子复合型材技术领域，具体涉及一种芳纶粉末复合注塑履带芯金及其生产工艺。
背景技术
橡胶履带属于行走部件，因为其具有对地接触面大，拥有防滑、防陷以及对路面损坏小等优点，所有其被广泛用于沙滩车、雪地车、全地形车等工程机械以及农业机械领域。橡胶履带主要由芯金、连接销和橡胶体组成，目前橡胶履带的芯金多为铸钢件材质或复合材料，目前的铸钢件材质或复合材料芯金强度不足，容易产生变形，导致塑钢型材产品的使用寿命较短，影响了塑钢型材的使用效果。
芳纶全称为“聚对苯二甲酰对苯二胺”，是一种新型高科技合成纤维，具有超高强度、高模量和耐高温、耐酸耐碱、重量轻、绝缘、抗老化、生命周期长等优良性能，广泛应用于复合材料、防弹制品、建材、特种防护服装、电子设备等领域。
发明内容
本发明提供了一种芳纶粉末复合注塑履带芯金及其生产工艺，以解决现有技术存在的强度不足和使用寿命较短的问题。
本发明解决其技术问题所采用的技术方案是：
一种芳纶粉末复合注塑履带芯金，包括芳纶骨架和壳体，壳体为超高分子量聚乙烯材质外壳，超高分子量聚乙烯材质外壳包覆在芳纶骨架表面。
上述芳纶粉末复合注塑履带芯金的生产工艺，首先将芳纶粉末经涂胶和除静电工艺处理后，再经过高温130℃～180℃，10MPa～16MPa压力环境下压制形成芳纶骨架，然后在120℃～150℃、9MPa～12MPa的压力下将超高分子量聚乙烯包覆在芳纶骨架表面，使超高分子量聚乙烯与内部芳纶粉末融为一体。
本发明将芳纶材料作为骨架材料用于履带芯金中，大大提高了履带芯金的强度和使用寿命，经检测本发明的履带芯金相对于普通的履带芯金，强度提高了2倍，寿命提高了3倍。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图。
图中1芳纶骨架、2壳体。
具体实施方式
如图所示，一种芳纶粉末复合注塑履带芯金，包括芳纶骨架和壳体，壳体为超高分子量聚乙烯材质外壳，超高分子量聚乙烯材质外壳包覆在芳纶骨架表面。
上述芳纶粉末复合注塑履带芯金的生产工艺，首先将芳纶粉末经涂胶和除静电工艺处理后，再经过高温130℃～180℃，10MPa～16MPa压力环境下压制形成芳纶骨架，然后在120℃～150℃、9MPa～12MPa的压力下将超高分子量聚乙烯包覆在芳纶骨架表面，使超高分子量聚乙烯与内部芳纶粉末融为一体。
本发明将芳纶材料作为骨架材料用于履带芯金中，大大提高了履带芯金的强度和使用寿命，经检测本发明的履带芯金相对于普通的履带芯金，强度提高了2倍，寿命提高了3倍。
