Description
技术领域
本发明涉及精细化工技术领域,具体为一种以黑滑石为原料制备轮胎气 密层用空气阻止剂的方法。
背景技术
黑滑石是我国工业滑石的一种,因在分子层间存在一层类石墨烯片层结 构,因此呈现出黑色。黑滑石属于一种层状镁质硅酸盐矿物,其莫氏硬度仅 为1-1.5、化学性质稳定、耐高温和酸碱腐蚀。黑滑石主要矿物组成为滑石、 石英、方解石,白云石和有机碳,其主要化学成分为氧化镁、氮化硅、氧化 钙、氧化铝以及少量的氧化铁、氧化钠、氧化钛等。我国黑滑石储量极为丰 富,国内已探明储量为6-8亿吨,90%的储量都分布在辽宁、山东、广西、湖 南、江西、青海等几省。各省滑石矿因伴生矿物的种类、含量以及成矿机理 的不同,其物理特性也显示出较大的差异,如山东烟台和辽宁海城的黑滑石 矿煅烧后会有珍珠光泽、江西广丰的黑滑石滑腻感差但煅烧后白度高、广西 上林黑滑石矿滑腻感强但煅烧后白度稍低,而湖南常德的滑石矿片状结构好。
黑滑石因为白度较低大大限制其应用范围,目前黑滑石其主要用途是经 高温煅烧增白后再进行超细粉碎生产高档陶瓷及釉面料,产品价格在 800-1200元/吨。该利用途径能耗高、产品附加值低、未能实现对黑滑石资源 的充分利用。因此,如何根据不同地区黑滑石矿本身的物理和化学特性,寻 找合适的应用领域,通过合适的加工手段,保留其本身的片状特性,生产出 高径厚比的产品,是实现黑滑石功能化高附加值绿色应用的必经之路。
现有技术当中制备轮胎气密层用空气阻止剂的方法的粉碎的精度有待提 高,难磨的伴生矿物及重金属杂质难以排除,产品纯度不高,同时黑滑石粉 的分散性和橡胶基体亲和性有待提高,因此亟需研发一种以黑滑石为原料制 备轮胎气密层用空气阻止剂的方法。
发明内容
本部分的目的在于概述本发明的实施方式的一些方面以及简要介绍一些 较佳实施方式。在本部分以及本申请的说明书摘要和发明名称中可能会做些 简化或省略以避免使本部分、说明书摘要和发明名称的目的模糊,而这种简 化或省略不能用于限制本发明的范围。
鉴于上述和/或现有以黑滑石为原料制备轮胎气密层用空气阻止剂的方 法中存在的问题,提出了本发明。
因此,本发明的目的是提供以黑滑石为原料制备轮胎气密层用空气阻止 剂的方法,能够有效的提高粉碎的黑滑石粉粉碎的精度,提高黑滑石粉的分 散性和橡胶基体亲和性,同时难磨的伴生矿物及重金属杂质能有效的排除。
为解决上述技术问题,根据本发明的一个方面,本发明提供了如下技术 方案:
一种以黑滑石为原料制备轮胎气密层用空气阻止剂的方法包括以下步 骤:
步骤一:原矿预处理:原矿预处理包括水洗和筛选两个步骤,所述水洗 是利用水洗的方法去除矿石表面附着的黏土类杂质,所述筛选是手工剔除出 石英、方解石、白云石、磁铁矿等伴生矿物;
步骤二:粗碎:利用粗碎设备将原矿粉碎至80-200目;
步骤三:磁选:利用磁选机将粗碎后物料中含铁量较高的颗粒去除;
步骤四:超细粉碎改性一体化:利用粉碎和改性一体化设备将粗碎后物 料在合适助剂的作用下超细粉碎至一定粒度;
步骤五:后处理:将超细改性后物料在一定温度下进行充分混合一段时 间,以保证改性剂均匀涂覆和反应完全,并将物料内残余的水去除。
作为本发明所述的以黑滑石为原料制备轮胎气密层用空气阻止剂的方法 的一种优选方案,其中:所述粗碎设备为颚式破碎机、辊压机、反击锤式破 碎机、圆锥式破碎机、雷蒙磨、立磨中的两种及以上组合。
作为本发明所述的以黑滑石为原料制备轮胎气密层用空气阻止剂的方法 的一种优选方案,其中:所述磁选机其磁场大小可调,粗碎物料铁含量控制 在1%-0.1%。
作为本发明所述的以黑滑石为原料制备轮胎气密层用空气阻止剂的方法 的一种优选方案,其中:所述超细粉碎改性一体化的主体设备为气流动能磨, 所述气流动能磨顶部均布4-8个雾化喷头,所述气流动能磨顶部有1-6个分 级机,分级机转速在100-4500rpm内可调,以控制粉碎后物料粒度,所述气 流动能磨底部有排渣口,将难粉碎的伴生矿物排除,所述排渣口的排渣量可 通过耐高温旋转卸料阀控制,所述气流动能磨所用过热气流压力为0.5-1MPa, 温度为250-320℃,所述气流动能磨磨内温度为180-230℃。
作为本发明所述的以黑滑石为原料制备轮胎气密层用空气阻止剂的方法 的一种优选方案,其中:所述助剂是由雾化喷嘴由磨顶喷入,所述助剂用量 为粉体总质量的0.3-1.5%,在助剂的作用下将粗碎后物料粉碎至1250-5000 目。
作为本发明所述的以黑滑石为原料制备轮胎气密层用空气阻止剂的方法 的一种优选方案,其中:所述助剂为硅烷偶联剂、铝酸酯偶联剂、钛酸酯偶 联剂、助磨偶联剂、稀土偶联剂、碱金属类脂肪酸盐、聚丙烯酸铵、聚丙烯 酸钠、六偏磷酸钠和三聚磷酸钠中的一种或几种。
作为本发明所述的以黑滑石为原料制备轮胎气密层用空气阻止剂的方法 的一种优选方案,其中:所述后处理设备为高速混合机,所述后处理温度为 80-120℃,时间为3-15min。
与现有技术相比:利用气流动能磨,利用干法粉碎工艺,在较高温度下 对通过物料自撞击和自摩擦的方式进行粉碎,并借助于滑石层间水的迅速蒸 发进行快速剥片,粉碎效率高,能耗低,粉碎后样品片状结构完整,径厚比 大,粒度细且分布窄。通过粉碎改性一体化工艺,在高温下进行对黑滑石进 行原位复合改性,缩短了工艺流程的同时,也使改性效果和粉碎效率大幅提 升,实现偶联和分散的双重作用。借助于磁选和排渣过程将难磨的伴生矿物 及重金属杂质排除,提高了产品纯度。通过该工艺生产出的超细改性黑滑石 粉细度可达5000目,片层厚度达到纳米级,平均径厚比约为30-40,比表面 积高达14m2,并且分散性佳与橡胶基体亲和性好,在轮胎气密层中应用可起 到优良的气密性和一定补强性能。

4.根据权利要求1所述的一种以黑滑石为原料制备轮胎气密层用空气阻止剂的方法,其特征在于:所述超细粉碎改性一体化的主体设备为气流动能磨,所述气流动能磨顶部均布4-8个雾化喷头,所述气流动能磨顶部有1-6个分级机,分级机转速在100-4500rpm内可调,以控制粉碎后物料粒度,所述气流动能磨底部有排渣口,将难粉碎的伴生矿物排除,所述排渣口的排渣量可通过耐高温旋转卸料阀控制,所述气流动能磨所用过热气流压力为0.5-1MPa,温度为250-320℃,所述气流动能磨磨内温度为180-230℃。
5.根据权利要求1所述的一种以黑滑石为原料制备轮胎气密层用空气阻止剂的方法,其特征在于:所述助剂是由雾化喷嘴由磨顶喷入,所述助剂用量为粉体总质量的0.3-1.5%,在助剂的作用下将粗碎后物料粉碎至1250-5000目。
6.根据权利要求1所述的一种以黑滑石为原料制备轮胎气密层用空气阻止剂的方法,其特征在于:所述助剂为硅烷偶联剂、铝酸酯偶联剂、钛酸酯偶联剂、助磨偶联剂、稀土偶联剂、碱金属类脂肪酸盐、聚丙烯酸铵、聚丙烯酸钠、六偏磷酸钠和三聚磷酸钠中的一种或几种。
7.根据权利要求1所述的一种以黑滑石为原料制备轮胎气密层用空气阻止剂的方法,其特征在于:所述后处理设备为高速混合机,所述后处理温度为80-120℃,时间为3-15min。
