Description

用于弹性体材料构成的制品的加强层、以及车辆充气轮胎
技术领域
本发明涉及一种用于由弹性体材料构成的制品、优选是用于车辆轮胎的用橡胶处理的加强层，其中，该加强层具有被布置成彼此平行且彼此间隔开的多个织物强化构件，其中，每个织物强化构件由至少一根加捻的复丝纱线构成，并且其中该织物强化构件不是由人造丝材料构成。本发明还涉及一种车辆充气轮胎。
背景技术
用于由弹性体材料构成的制品(例如像工业橡胶产品和车辆(充气)轮胎)的加强层是极其重要的，并且通常是本领域技术人员已知的。这些加强层具有多个加强的线形元件，这些加强的线形元件被称为强化构件。将它们完全嵌入弹性体材料中。这些加强层的强化构件具有例如织物或压延的连续盘绕的强化构件的形式。
使具有合适尺寸和设计的用橡胶处理的加强层与另外的部件结合以形成工业橡胶产品或车辆充气轮胎。在此，用橡胶处理的加强层加强了所讨论的产品。
EP 0 908 329 B1中已经披露了一种加强层，该加强层具有由PET、PEN和芳族聚酰胺构成的复丝纱线制成的织物帘线。由于所使用的纱线线性密度和PEN帘线的构造使得它们是相对薄的，因此该用橡胶处理的加强层具有相对低的层厚度。这首先具有的优点是，必须使用较少的橡胶材料来对这些强化构件进行橡胶处理，这节省了材料成本。其次，在产品例如车辆轮胎中薄的用橡胶处理的加强层具有的优点是，减少了该轮胎的重量并且还产生较低的滞后，这在该轮胎的滚动阻力上具有积极作用。
然而，除了由于薄的层厚度减轻重量并降低滞后之外，这个加强层的强度也是必不可少的，以便能够充分吸收轮胎中产生的力。
发明内容
因此，本发明的目的是提供一种用于由弹性体材料构成的制品的加强层，该加强层具有相对薄的形式，然而对轮胎中产生的力具有足够的强度。本发明的另外的目的是提供一种车辆充气轮胎，该车辆充气轮胎在具有良好的结构耐久性的同时，在滚动阻力方面进行了优化。
关于加强层的目的得以实现在于加强层满足以下条件：
以mm为单位的(D2/E0)对应于从0.22mm至0.38mm范围内的值，并且在于该加强层具有10kN/dm<x<25kN/dm的强度，
其中，D是以mm为单位的该织物强化构件的直径、并且是在从0.38mm至0.52mm的范围内，并且
其中，E0＝100/epdm。
产生了加强层，该加强层具有相对较小直径的强化构件。对加强层、尤其是其厚度的橡胶处理以本领域技术人员惯用的方式进行配置，其结果是可获得相对薄的加强层。此加强层具有10kN/dm<x<25kN/dm的强度，该强度对于具有织物强化构件的加强层、尤其是对于乘用车轮胎而言是足够的强度。
本发明明确地排除了由人造丝材料构成的强化构件。
“epdm”是指每分米的经纱并且描述了加强层中的强化构件密度。
表述“加强层的强度”是指加强层在kN/dm(分米)下的断裂力，这是由各强化构件的断裂力乘以此加强层中每dm的强化构件的数量计算得到的，其中，断裂力是根据ASTMD885M确定的。
在本发明的优选的实施例中，加强层满足以下条件：
以mm为单位的(D2/E0)对应于从0.31mm至0.38mm范围内的值。
利用此数值范围实现了层厚度与强度之间的最佳折衷。此外，强化构件在加强层中不是太紧密地填充，其结果是在层中仍然有充足的橡胶来确保帘线之间的力传递。
在本发明的一个优选的实施例中，该强化构件具有从0.38mm至0.45mm范围内、优选是从0.42mm至0.45mm范围内的直径。利用此数值范围实现了层厚度与强度之间的最佳折衷。
对于轮胎性能有益的是，加强层具有11kN/dm<x<14kN/dm的强度。这代表了加强层的厚度与其强度之间的目标冲突的最佳解决方案。
在本发明的一个优选的实施例中，强化构件是由两根捻绕在一起的复丝纱线构成的帘线，并且强化构件以从150epdm到220epdm范围内、优选是从170epdm到180epdm范围内的密度布置在此加强层中。一方面，前述密度是在加强层的耐久性与力传递之间优化的折衷，对此在强化构件之间必须存在特定橡胶体积；另一方面，是在强度与轮胎性能耐久性之间优化的折衷，对此强化构件在加强层中不得间隔太远。
有利的是，强化构件由材料PET、PEN或比如尼龙PA66、PA46、PA6等脂族聚酰胺、或比如对芳族聚酰胺、间芳族聚酰胺、PBO等芳族聚酰胺、或上述材料的组合构成。上述材料的组合形成所谓的混合强化构件，其中一根纱线由第一材料构成，一根或多根其他纱线由不同于第一材料的第二或其他材料构成。
在本发明的一个优选的实施例中，帘线具有构造550dtex x 2、直径为0.45mm，其中，两根纱线均由PET构成并且以175epdm的密度布置在此加强层中，并且其中，该加强层具有大约11.38kN/dm的强度。
在本发明的另一个优选的实施例中，帘线具有构造630x 2、直径为0.51mm，其中，两根纱线均由PET构成并且以175epdm的密度布置在此加强层中，并且其中，该加强层具有大约13kN/dm的强度。
对于车辆充气轮胎，本发明得以实现在于所述轮胎具有至少一个上述加强层。
此加强层是胎体和/或带束箍带和/或胎圈加强件。此加强层优选地是乘用车充气轮胎的胎体。
在本发明的一个特定实施例中，该车辆充气轮胎除了上述加强层(优选地是胎体)之外，还具有由用橡胶处理的强化构件构成的带束层，该带束层满足以下条件：
以mm为单位的(D2/E0)对应于从0.07mm至0.43mm范围内的值，并且该加强层具有16.5kN/dm<X<55kN/dm的强度，其中，D是以mm为单位的该强化构件的直径，并且其中，E0＝100/epdm。
有利的是，该具有织物强化构件的加强层的强度与该带束层的强度之和为≥40kN/dm。确保了充足的整体强度。
带束层的强化构件优选地由至少一根钢长丝构成，该至少一根钢长丝具有在从0.26mm至0.35mm的范围内的直径。这些小的直径对于优化的滚动阻力是有利的。
在本发明的一个优选的实施例中，强化构件具有构造1x 0.30mm或2x 0.30mm并且以80epdm至120epdm范围内的密度布置在带束层中。一方面，前述密度是在加强层的耐久性与力传递之间优化的折衷，对此在强化构件之间必须存在特定橡胶体积；另一方面，是在强度与轮胎性能耐久性之间优化的折衷，对此强化构件在加强层中不得间隔太远。
构造1x 0.30mm、密度为110epdm的钢单丝优选地布置在带束层中，其中，此带束层具有大约24kN/dm的强度。
在另一个优选的实施例中，构造2x 0.30mm、密度为80epdm的钢帘线布置在带束层中，其中，此带束层具有大约35kN/dm的强度。
