Description

一种基于玄武岩纤维的轮胎冠带层及其制造方法
技术领域
本发明属于轮胎冠带层制造领域，具体的说，尤其涉及一种基于玄武岩纤维的轮胎冠带层及其制造方法。
背景技术
我国使用玄武岩纤维作为轮胎冠带层还是空白，目前主要使用N66、芳纶、涤纶等材料作为冠带层，然而N66和涤纶由于材料本身的特性，对防轮胎热胀大的效果不理想，芳纶的价格则过高。玄武岩纤维综合性能好，具有高模量，耐热性好，耐酸碱性能优异，几乎无蠕变、性价比高等特点，能够满足子午线轮胎冠带层的要求，采用基于玄武岩纤维的轮胎冠带层，轮胎操作性能更好，使用寿命更长，可降低能耗，不仅如此，玄武岩纤维更是环保型材料，有利于废旧轮胎的再利用，是轮胎冠带层中具有革命性的材料。

所述冠带层由至少一圈线绳组成。
所述冠带层由至少一圈帘子布组成。
一种基于玄武岩纤维的轮胎冠带层的制造方法，包括如下步骤：
a、玄武岩粗纱的制备；
b、轮胎冠带层的制备。
所述步骤b中的轮胎冠带层为基于玄武岩纤维的线绳，其制备方法为将玄武岩粗纱进行捻线制得线绳，线绳再浸胶得到基于玄武岩纤维的线绳。
所述步骤b中的轮胎冠带层为基于玄武岩纤维的线绳，其制备方法为将玄武岩粗纱进行浸胶制得浸胶纱，浸胶纱再进行捻线制得基于玄武岩纤维的线绳。
所述步骤b中的轮胎冠带层为基于玄武岩纤维的帘子布，其制备方法为将玄武岩粗纱进行捻线制得线绳，以线绳作为经纱，棉纱或者锦纶66外包棉纱的弹性纱作为纬纱制得帘子布，帘子布再浸胶制得基于玄武岩纤维的帘子布。
所述步骤b中的轮胎冠带层为基于玄武岩纤维的帘子布，其制备方法为将玄武岩粗纱进行捻线制得线绳，线绳浸胶后作为经纱，棉纱或者锦纶66外包棉纱的弹性纱作为纬纱，最终得到基于玄武岩纤维的帘子布。
步骤中的浸胶过程包括一浴活化及二浴RFL体系浸胶，一浴活化组分可采用硅烷偶联剂、马来酸酐、钛酸酯偶联剂、缩水甘油醚型环氧树脂中的一种或多种，总固含量为0.1％-10％，一浴烘干温度为50-200℃，烘干时间为0.5-3min，二浴RFL体系包括胶乳、和间甲树脂，间甲树脂与胶乳含固量比例为10％-25％，体系总含固量为15％-25％，所述胶乳可采用丁苯胶乳、丁腈胶乳、丁吡胶乳、天然胶乳、二元或三元乙丙橡胶胶乳、氯磺化聚乙烯胶乳中的一种或多种，二浴烘干温度为100-250℃，烘干时间为0.5-3min。
