Description
技术领域
本发明涉及一种涂覆布，具体涉及一种表面电阻稳定性高的矿用涂覆布。
背景技术
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表面电阻稳定性不佳，容易造成静电积聚，进而产生静电火花，造成安全隐患。
发明内容
本发明旨在提供一种表面电阻稳定性高的矿用涂覆布。
本发明通过以下技术方案来实现：
一种表面电阻稳定性高的矿用涂覆布，由纺织基材和表面涂覆液制成，所述纺织基材是由天然植物纤维织造的布匹基材，所述表面涂覆液由如下重量份的物质制成：26~29份聚氯乙烯、13~15份聚碳酸酯、3~5份聚对苯二甲酸乙二醇酯、4~6份改性黑铅硅石粉、1~2份抗氧化剂、0.5~1份紫外线吸收剂、1~2份消泡剂、1~3份丙三醇、1~2份乙二醇丁醚；所述的改性黑铅硅石粉由如下重量份的物质制成：35~38份黑铅硅石、6~8份水镁石、5~7份蒙脱石、2~4份十六烷基三甲基氯化铵、3~5份双十八烷基二甲基氯化铵、1~2份乙二胺四乙酸二钠、0.5~1份硝酸稀土盐、1~3份季戊四醇。
进一步的，所述的抗氧化剂为抗氧化剂1010、抗氧化剂168、抗氧化剂164中的一种。
进一步的，所述的紫外线吸收剂为紫外线吸收剂UVP-327、紫外线吸收剂UV-O、紫外线吸收剂UV-531中的一种。
进一步的，所述的消泡剂为聚氧乙烯聚氧丙烯季戊四醇醚、聚氧乙烯聚氧丙醇胺醚、聚氧丙烯甘油醚中的一种。
进一步的，所述的改性黑铅硅石粉的制备方法为：先将黑铅硅石放入质量分数为4%的硫酸溶液中浸泡处理20~25min，取出后用去离子水冲洗干净，再放入温度为800~840℃的条件下煅烧处理2h，然后将其与水镁石、蒙脱石共混粉碎过400目得混合粉末，最后将混合粉末同十六烷基三甲基氯化铵、双十八烷基二甲基氯化铵、乙二胺四乙酸二钠、硝酸稀土盐、季戊四醇混合放入反应釜中，同时配入其总质量3倍的清水，加热保持温度为96~98℃，不断搅拌反应7~8h后过滤，将滤渣干燥至水含量不大于5%即可。用十六烷基三甲基氯化铵、双十八烷基二甲基氯化铵等成分对黑铅硅石、水镁石和蒙脱石进行表面和插层改性处理，可有效改变其吸温特性，提升其分散、附着能力，并有效提升了其电性能和稳定性。
进一步的，所述的表面涂覆液的制备方法为：将聚氯乙烯、聚碳酸酯、聚对苯二甲酸乙二醇酯、改性黑铅硅石粉、抗氧化剂、紫外线吸收剂、消泡剂、丙三醇、乙二醇丁醚共同混合后，加热至48~53℃，不断搅拌分散均匀后即可。
一种表面电阻稳定性高的矿用涂覆布的制备方法，具体为：将表面涂覆液通过涂布辊均匀涂布于纺织基材上，控制涂层厚度为0.6~1mm，然后再对其进行烘干处理即可。
本发明具有如下有益效果：
本发明针对现有涂覆布表面涂层的缺陷进行了改进，以聚氯乙烯、聚碳酸酯为主要基体物质，为涂层奠定了很好的理化基础，同时为了进一步增强整体的特性，而对应添加了改性黑铅硅石粉成分，改性后的黑铅硅石具有良好的耐温阻燃特性，又具有良好的电性能，可有效防止静电的积聚。最终本发明制得的涂覆布具有良好的耐腐、耐磨、耐温特性，同时其表面电阻特性好且稳定，可有效降低静电积聚现象的发生，进而降低了火灾的发生率。
