导风筒在煤矿井下局部通风系统中起着引导空气，稀释和排除工作地点释放出的瓦斯气体，排除生产中产生的煤尘、岩尘,防止矿尘堆积与爆炸的作用，为作业现场提供良好的生产作业环境。目前，大量用于煤矿井下的导风筒主要以玻璃纤维布、玻棉交织布、化学纤维布、合成纤维布等为骨架材料，以橡胶、塑料或橡塑混合物等为涂覆层的涂覆布制成的柔性导风筒。现有的多数导风筒材料耐温阻燃性不佳，仍不能有效防止灾害的发生。
发明内容
本发明旨在提供一种矿用导风筒耐温阻燃涂覆布。
本发明通过以下技术方案来实现：

进一步的，所述改性麦饭石的制备方法包括如下步骤：
（1）先将麦饭石放入质量分数为5%的氢氧化钠溶液中浸泡处理13~15min，取出后用去离子水冲洗干净，然后放入温度为670~720℃的条件下煅烧处理2~3h，取出后同水滑石共同混合粉碎过500目得混合粉末备用；
（2）将十二烷基三甲基溴化铵、十二烷基硫酸钠、聚乙烯吡咯烷酮、乙二醇与其总质量5~6倍的清水共同混合，搅拌均匀后得混合液备用；
（3）将步骤（1）所得的混合粉末同步骤（2）所得的混合液一起放入反应釜中，加热保持反应釜温度为90~94℃，并升压至0.3~0.4MPa，不断搅拌反应4~5h后过滤得滤渣备用；
（4）将步骤（3）所得的滤渣放入去离子水中清洗后，再放入温度为80~85℃的干燥室内干燥，最后粉碎过600目即得改性麦饭石。
进一步的，所述复合涂覆剂的制备方法为：先将聚氯乙烯、聚乙烯、聚苯硫醚、消泡剂、乳化剂、异丙醇共同混合，加热保持温度为42~45℃，不断搅拌分散均匀后，再将改性麦饭石加入，继续搅拌直至分散均匀即可。
一种矿用导风筒耐温阻燃涂覆布的制备方法，包括如下步骤：
（1）将组分B利用涂布辊采取逆辊式涂布于组分A的外表面上，控制涂布的厚度为0.5~0.8mm；
（2）将步骤（1）涂布后的组分A置于远红外烘干室内，保持烘干室内温度为90~95℃，持续烘干即可。
本发明具有如下有益效果：
本发明合理搭配了聚氯乙烯、聚乙烯、聚苯硫醚成分作为基体物质，保证了整体的耐温、耐腐、抗老化性能，并添加了改性麦饭石对整体特性做进一步改善，用十二烷基三甲基溴化铵、十二烷基硫酸钠等成分对麦饭石和水滑石进行表面和插层改性处理，改变了其吸温特性，提高了耐温性能，进而提升了复合涂覆剂的耐温阻燃性能。在各方法步骤的共同配合作用下，本发明制得的涂覆布耐温阻燃性能强，耐腐、耐磨性能好，表面涂层与基材粘附性好，降低了意外事故的发生率。
