Description

技术领域
一种轮胎胎面胶料及制备方法,属于胎面胶料领域;尤其涉及一种具有仿生结构的高耐磨轮胎胎面胶料及合成制备方法。
背景技术
随着国家经济实力的不断增强,汽车产业得到迅猛的发展,汽车已经成为人们生活中必不可少的重要交通工具。轮胎胎面是汽车唯一与地面直接接触部件,承受外界应力最苛刻,受到来自外部各种恶劣环境的冲击,包括与地面之间的摩擦,外界尖锐物质的刺穿,粗糙路面对它的震动以及冲击等等。这就要求轮胎具有优良的耐磨、耐切割、耐撕裂、抗湿滑性以及低滚阻、低生热和耐老化性能等。但是轮胎各种性能之间往往是相互矛盾的,难以同时提高性能,提高一种或两种性能的同时,第三种性能往往会降低,轮胎的耐磨性、滚动阻力和抗湿滑(抓地性)三大性能被称为“魔鬼三角”。轮胎胎面胶的耐磨性能直接影响轮胎的安全性、噪声、振动和磨耗里程,因此提高轮胎胎面胶耐磨性同时保证滚动阻力和抗湿滑性具有很重要的意义。
仿生学设计作为一种独具特色的设计方法,其工业设计主要集中于形态仿生、肌理仿生、质感仿生、结构仿生、功能仿生、色彩仿生和意象仿生7个方面。轮胎作为汽车的重要组成部分,其仿生设计主要集中于结构仿生和功能仿生两个方面。现有技术中的各大企业和高效利用仿生学与轮胎结构的研究结合,对轮胎的外部结构进行结构上的改良使轮胎的安全性和经济性得到更高的提升,但很多仿生的轮胎实验验证过程都非常繁琐,对于不同路面的实验效果也不尽相同,需要投入非常大的人力物力进行轮胎检测,仿生学与轮胎的研究很多只是停留在研究阶段,轮胎的耐磨性能和低滚动阻力性能方面的改善效果不高。

具体实施方式
图1示出了根据本发明的一个实施例的整体结构示意图。该图与其它包括在内的图一起仅是示性意的,并不限制本发明的可能实施例或权利要求。
实施例一:本实施例的一种具有仿生结构的高耐磨轮胎胎面胶料,包括上下布置的第一胶料层1和第二胶料层2,第一胶料层1为低滚动阻力材料层,第二胶料层2为高耐磨材料层,第二胶料层2的上端面向上延伸形成若干均匀阵列排布的六棱柱3,第一胶料层1上开有上下贯通的插孔4,插孔4的位置和形状与所述六棱柱3的位置和形状匹配对应,第二胶料层2的六棱柱3嵌插在第一胶料层1的插孔4内且六棱柱3与插孔4过盈配合,第一胶料层1和第二胶料层2嵌插压装后,六棱柱3的顶端延伸出第一胶料层1的上端面形成抓地颗粒,相邻两六棱柱3之间的距离小于抓地颗粒的高度。
为了使本实施例中的抓地颗粒形成的胶料表面具有更好的耐磨性能,所述抓地颗粒与第一胶料层1的上端面之间形成沟槽,沟槽的纵截面呈矩形,相邻两六棱柱3之间的距离D与抓地颗粒高度H4的比值范围为10:23-5:9之间,使用矩形截面的沟槽结构,相邻六棱柱3之间的距离与抓地颗粒高度H4的比值在合理范围内,沟槽与抓地颗粒提高了复合胎面胶料具有较高的黏附力和较高的摩擦力,而且减小六棱柱3与插孔4内壁夹角处受力,防止插孔4内壁的夹角处出现损伤。
由于第一胶料层1和第二胶料层2之间通过六棱柱3的嵌插结构建立连接,而复合胎面胶料本身具有一定的弹性,在使用过程中六棱柱3的侧面与插孔4侧壁之间根据受力位置不同会出现不同程度的变形情况,虽然轻微的形变在受力撤销后可以恢复,但在长时间使用后,插孔4形状会出现不能恢复的形变,这种形变会六棱柱3与插孔4内壁之间留有缝隙,不仅可能会有外部杂质混入,而且会使插孔4的变形程度越来越严重,会辐射到其相邻区域的插孔4,出现大区域的变形影响,整体稳定性都可能会遭到破坏,因此,所述第一胶料层1的由上橡胶层5、聚脲弹性层7和下橡胶层6硫化加压而成,本实施例在第一胶料层1的中部增加聚脲弹性层7,在使用过程中,聚脲弹性层7快速分散六棱柱3侧壁对于插孔4内壁的应力,将产生的动能及时消耗掉,不会增加胎面胶料的重量和厚度。
所述上橡胶层5、聚脲弹性层7和下橡胶层6之间的厚度比为1.3:1:1.3,聚脲弹性体具有良好的抗冲击性能,与六棱柱3直接接触的面积越大具有的抗变形能力越好,但胎面胶料在厚度上具有严格要求,在使用过程中,胎面的外侧面受力才是其受力的重点部位,因此,本实施例设置合理的厚度分布,使第一仿生胶料层的机械性能显著提高,也就是提高了整体胎面胶料的机械性能。

(1)第二胶料层制成六棱柱体形状轮胎胶料如图3,其制成底座高度H2为0.2-2mm,制成的六棱柱高度H3为0.6-4mm,制成的六棱柱边长A1为3-8mm,两个六棱柱之间的距离D为0.2-1mm。
