Description

一种阻燃耐热输送带
技术领域
本发明涉及输送带制造领域，具体涉及一种阻燃耐热输送带。
背景技术
目前，在冶金、钢铁行业现场使用的输送带为了适应现场的使用环境要求，国产的输送带基本以提高耐热性能为主，但在许多使用现场的环境中，高温的物料往往带有明火，很容易将不具备阻燃性能的耐热输送引燃，对设备和工作现场的人员生命带来极大隐患。
由于在炼钢厂、热电厂、水泥厂等企业，输送机械所运送的物料都是高温物料，若采用金属履带输送物料，不仅动力消耗大，热损失大，而且容易造成人员伤害，操作起来很不方便，因此重量轻、强度好的输送皮带越来越受到业界的青睐。，氝的输送带的耐热性能普遍不好，主要原因是骨架材料承受不了高温，而且胶面自身的耐温和耐热性较差，在高温环境下输送带的胶面因碳化烧结成贵裂纹，由于龟裂纹路较大形成缝隙，高温物料的热量容易迅速向带芯的骨架层传递，从而降低输送带寿命。专利号为02261969.0的中国专利公布了一种输送带，改输送带在覆盖胶同骨架之间增加一层绝热层和石棉之类以阻止高温向帆布骨架传递，但其耐温也仅在200摄氏度左右，扔不能满足业界对输送带耐高温的要求。
发明内容
本发明所要解决的问题是提供一种使用范围广泛，阻燃性能好，可以满足用户要求的阻燃耐热输送带。
为了实现上述目的，本发明采取的技术方案为：所提供的一种阻燃耐热输送带，所述输送带包括以下组份(质量百分数): 三元乙丙胶60~100份、三元乙丙再生胶60~100份、炭黑 30~60 份、耐热剂 7~13 份、氧化锌 12~15 份、复合阻燃剂 10~20 份、高温稳定剂3~10份、硬脂酸 1~3 份、酚醛树脂BN-1 1~10份、促进剂 1.5~5 份、硫化剂 1.5~3 份、氢氧化铝 2~5 份、防老剂1~3 份，硫磺 0.1~0.3 份。
优选的，所述阻燃耐热输送带中三元乙丙胶的含量(质量百分数)：50~60%。
优选的，所述的复合阻燃剂包括硼酸锌、TBC、八钼酸铵、多聚磷酸铵、氯化石蜡。
优选的，所述的促进剂包括次磺酰胺类促进剂 CZ、促进剂NOBS。
优选的，所述的防老剂包括防老剂BLE、防老剂BLE-W和防老剂BLE-C。
本发明的有益效果：本发明具有难燃特性，阻燃氧指数35%~40%之间 ；耐热特性，250度条件下，拉伸强度和扯断伸长率均小于20%（GB/T3512）。由于本发明采用阻燃、耐热胶料做覆盖层和芯层胶料，解决了现有耐热带不具备阻燃性能，可能引起严重灾害、危害人员生命安全的问题，是一种具有阻燃、耐热性能的安全制品，且原料易得均可市购，生产工艺简单，适用于工业化生产。
具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体实施方式，进一步阐述本发明。
实施例1：
一种阻燃耐热输送带，所述输送带包括以下组份(质量百分数): 三元乙丙胶85份、三元乙丙再生胶90份、炭黑40 份、氧化锌 13份、复合阻燃剂 17份、高温稳定剂8份、硬脂酸2份、酚醛树脂BN-1 6份、促进剂 3.5份、硫化剂 2.2份、氢氧化铝 5 份、防老剂2份，硫磺 0.1份。
基于上述，本发明是先将合成橡胶进行合炼，再与各种配合剂混合进行混炼制成混炼胶，混炼胶经压片、冷却、停放后进行压延成型制成带胚，带胚经梳化后既得本发明所诉的阻燃耐热输送带。
显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进，或未经改进将本发明的构思和技术方案直接应用于其它场合的，均在本发明的保护范围之内。
