Abstract

本发明公开了一种芳纶织物整芯阻燃输送带及其制造方法，该输送带包括覆盖层、芳纶织物整体带芯及带芯浸渍胶料：覆盖层采用PVC／CM／TPU共混热塑性弹性体，阻燃性能好，拉伸强度高，弹性优异，耐磨性能好，与浸胶塑化后的整体带芯粘合强度高；织物整体带芯3层结构，径向受力线采用芳纶纤维，强度高，带体薄，重量轻，可使输送带运行过程中的能耗大幅度降低；带芯浸渍胶料中含有MDI增粘剂，使塑化后的整体带芯与覆盖层的粘合强度大幅度提高，确保输送带长期运行不脱层。本发明采用真空浸渍整体带芯、挤出机贴面成型、动态硫化工艺生产输送带，工艺简单、能源消耗低、生产效率高。

Description

一种芳纶织物整芯阻燃输送带及其制造方法
技术领域
本发明涉及一种煤矿井下用阻燃输送带，具体地说是一种芳纶织物整芯阻燃输送带及其制造方法。
背景技术
煤矿井下使用的输送带主要是织物整芯阻燃输送带和钢丝绳芯阻燃输送带。现有技术的织物整芯阻燃输送带阻燃性能好，重量轻，价格便宜，接头速度快，安装维修方便，且能源消耗低，所以用量特别大，占煤矿井下输送带用量的75%左右，但现有技术的织物整芯阻燃输送带使用尼龙、涤纶和棉纤维作为整体带芯的编织材料，受编织材料强度的限制，当阻燃带强度超过2000N/mm时，整体带芯需编织成5层及以上结构，厚度在15mm以上，浸渍浆料困难，影响阻燃带的阻燃性能、内部粘合性能、成槽性能和使用寿命，因此，目前煤矿井下使用的整芯阻燃输送带的最高强度为2500N/mm,强度超过2500N/mm的整芯阻燃输送带未见使用报道。
发明内容
本发明的目的是克服现有技术的不足，提供一种芳纶织物整芯阻燃输送带，满足煤矿井下使用强度2500N/mm及以上高强力整芯阻燃输送带的需要。
本发明的另一目的是提供该输送带的制造方法，工艺简单，易于制造，生产成本低，生产效率高。
本发明的目的通过下述方案予以实现。
