一种多层级高强汽车轮胎帘子布及其制备方法
【技术领域】
本发明涉及帘子布的技术领域，特别涉及一种多层级高强汽车轮胎帘子布及其制备方法。
【背景技术】
帘子布是轮胎外胎的骨架材料，其重量约占外胎总重量的10％～15％，其成本约占轮胎生产成本的37％，是轮胎生产的主要原材料之一。目前轮胎帘子布主要有锦纶帘子布、涤纶帘子布、粘胶帘子布和钢丝帘布等。帘子布，是用强力股线作经，用中、细支单纱作纬，织制的轮胎用骨架织物。经线排列紧密，纬纱排列稀疏，状似帘子，故名帘子布，经线又称帘子线，承受负荷，纬纱固定经线位置。帘子布用作轮胎等橡胶制品的骨架，使其承受巨大压力、冲击负荷和强烈震动。帘子布是影响轮胎性能和寿命的重要材料。目前的帘布大多采用单层的结构，为了提高帘布的结构强度，有必要提出一种多层级高强汽车轮胎帘子布及其制备方法。

具体地，所述的第一放卷辊9、浸胶池12、复合辊13、烘干箱14和收卷辊15依次从前到后设置，所述的第二放卷辊10和第三放卷辊11位于浸胶池12和复合辊13之间，且第二放卷辊10位于中间层2的下方，第三放卷辊11位于中间层2的上方。
进一步地，所述的帘子布生产设备还包括压板16和位于压板16上方的压辊17，所述的压板16位于帘布坯布的下方，所述的压辊17位于帘布坯布的上方，所述的烘干箱14与收卷辊15还设置有冷却装置18，所述的烘干箱14为上下层结构，上层为预热室，下层为烘干室，帘布坯布先进入预热室预热，然后进入烘干室烘干定型，所述的帘布坯布在烘干箱14内循环前行。
更进一步地，所述的浸胶池12内安装有导向辊121，浸胶池12的前后侧上方设置有导辊122，中间层2经前侧的导辊122后穿过导向辊121再经过导辊122，所述的浸胶池12的后侧上方倾斜设置有挡胶板123，所述的挡胶板123末端与浸胶池12内连通，所述的浸胶池12内盛装有胶液，胶液的上平面没过导向辊121。
本发明一种多层级高强汽车轮胎帘子布，结构合理，采用三层级的结构，提高了汽车轮胎帘布的整体结构强度，中间层采用高强度钢丝5和弹性涤纶线6编织，高强度高耐磨高耐冲，内外复合由碳纤维丝和玄武岩纤维丝加捻而成的复合纤维线7与涤纶长丝81外包玄武岩纤维层82的包芯纱8编织而成的内层1和外层3，解决钢丝帘子线刚性大的问题，避免出现刚性磨损；内层1和外层3均采用玄武岩纤维，具有增粘的效果，提高内层1及外层3与中间层2的粘接强度；内层1和外层3还采用了碳纤维丝，具有抗拉抗剪抗震加固的效果，耐腐蚀，可有效保护内部的高强度钢丝5避免腐蚀，有助于延长帘子布的使用寿命。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本发明的保护范围之内。
