Description

具有双涂层的钢丝网
技术领域
本发明涉及一种适用于侵蚀控制、岩土工程解决方案、落石保护或水产业的钢丝网。
背景技术
用于侵蚀控制、岩土工程解决方案或落石保护的钢丝网存在于防侵蚀垫、石笼、拦石网、挡土墙等中。
这些钢丝网必须满足越来越严格的要求。这些钢网经受极端的气候环境，并且经常安装在自然界中的偏远地方。因此，钢丝网必须具有长寿命，这意味着它们必须具有高于平均值的耐湿性、耐腐蚀性、耐磨性和耐冲击性。另外，在生产期间不得损坏这些钢丝网的钢丝上的任何现有涂层。
已知用聚氯乙烯(称为PVC)来涂覆钢丝以为钢丝提供一些保护。然而，PVC涂层不能保证满足上述要求。PVC的缺点之一是它的吸湿性。另一个缺点是在钢丝网的生产期间(例如在捻绕或编织期间)可能会损坏PVC。另外，由于增塑剂的浸出，PVC随时间的推移而脆化。因为已知这些增塑剂会对生物体造成激素紊乱，所以这就引起了环境问题。此外，脆化将会导致粘合度和耐侵蚀冲击性降低，并且随着时间的推移而产生腐蚀斑点。
WO-A1-2004/003302公开了一种金属丝网，其中钢丝在钢丝的钢芯上直接覆盖有交联聚乙烯涂层。交联聚乙烯被称为XPLE。交联聚乙烯，特别是以低密度形式的交联聚乙烯，可以用碳黑来填充，并且用过氧化物来补充。
尽管事实上XPLE与PVC相比具有改善的机械性能，但它可能仍然不足以满足上述要求。
JP-300552-B2公开了一种由钢丝制成的石笼，其中钢丝具有双合成涂层。第一层是聚烯烃的耐冲击层。位于第一层上面的第二层是耐磨层，例如高密度聚乙烯的耐磨层。
双合成涂层增加了复杂性。
发明内容
本发明的一般目的是为了克服现有技术的缺点。
本发明的特别目的是为了提供一种钢丝网，该钢丝网通过增加例如耐腐蚀性、耐湿性、耐磨性和耐冲击性的性能而具有改善的使用寿命。
根据本发明的第一方面，提供了一种适用于侵蚀控制、岩土工程解决方案、落石保护或水产业的钢丝网。钢丝网包括钢丝。这些钢丝具有钢芯。钢芯具有低碳性质或高碳性质(见下文)。钢丝在钢芯上还具有锌或锌铝合金或锌铝镁合金的中间金属涂层。钢丝还具有表层聚合物涂层。聚合物是高密度聚乙烯。
已经证明了高密度聚乙烯在炎热气候中和在水下(如在河流中或在海中)随着时间推移在保证耐磨性、耐侵蚀性和耐久性的性能方面是有利的。该聚合物可以优选地通过挤出或优选地通过粉末喷涂而施加到钢丝上。
在本发明的优选实施例中，在中间金属涂层和表层聚合物涂层之间存在改性聚烯烃的中间粘合层(底涂料)。
该粘合层的存在大大增加了表层聚合物涂层和中间金属涂层之间的粘合度。
中间金属涂层的第一优选实施例是锌涂层和不可避免的杂质。该锌涂层可以通过电镀操作或通过热浸工艺施加到钢芯上。
热浸工艺是优选的方式。热浸工艺具有在钢芯和锌涂层之间形成薄的锌铁合金层的优点。该锌铁合金层具有非常脆的缺点，但是具有非常有利于中间金属涂层和钢芯之间的粘合的显著优点。因为钢丝网、侵蚀控制、岩土工程解决方案或落石保护的应用是静态应用，所以脆性性质不会形成障碍，并且不会妨碍改善的粘合度的巨大优点。
中间金属涂层还可以是锌铝合金或锌铝镁合金。锌铝合金的中间金属涂层同样具有比100％锌的中间金属涂层更好的耐腐蚀性。该锌铝合金涂层可以具有范围为从2wt％至12wt％的铝含量，例如范围为从3wt％至12wt％，即，4wt％至11wt％。一个示例是一种接近共晶成分的成分，其具有4wt％至6wt％之间的铝，其余为锌和不可避免的杂质。另一个示例是锌铝镁合金涂层，其包含2wt％至8wt％的铝和0.05％至3.0wt％的镁，余量为锌和不可避免的杂质。
优选的锌铝合金包含8wt％至12wt％的铝，其余为锌和不可避免的杂质。该优选的合金具有尤其在表面处存在大量的铝的优点。表面处的铝可以产生氢氧化铝，其为与底涂料或表层聚合物涂层的键合提供优异的基础。例如，可以经由不同单体的共聚作用或经由接枝到聚烯烃类聚合物上来将酸基引入到聚烯烃底涂料中。酸基可以与氢氧化铝反应以形成强键合。
优选地，聚合物是双峰型高密度聚乙烯，其具有选自于丁烷、己烷和辛烷的组中的至少一种共反应物。具有这类聚合物的涂层具有高的耐环境性。
最优选地，离聚物树脂、乙烯和甲基丙烯酸的共聚物以范围从10％至25％的量添加到聚合物中。这种添加具有改善耐侵蚀性的优点。
聚合物的可替代优选实施例是高密度聚乙烯，其中混合了10％至30％的线性低密度聚乙烯。该可替代方案还具有改善的耐侵蚀性和增加的强度。
根据本发明的金属丝网可以是包括焊接结构的任何类型的金属丝网，但优选地是双捻六角形网或链环围栏。
根据本发明的另一方面，提供了一种由上述金属丝网制成的石笼。
附图说明
图1是双捻六角形金属丝网的一部分的示意图。
图2是链环网状物的一部分的示意图。
图3是根据本发明的双涂层钢丝的横截面。
图4示出了用于粘合度测试的金属丝的制备。
具体实施方式
图1是双捻六角形金属丝网100的一部分的示意图。图1所示的部分具有四根双涂层钢丝102、104、106和108。这些钢丝102、104、106和108中的每一根交替地与左侧的相邻钢丝和右侧的相邻钢丝连接。每个连接部都通过将两个相邻的钢丝互相捻绕在一起而形成。互相捻绕部110示出了钢丝102与钢丝104的捻绕。因为是在整个金属丝网的全部宽度上以相同的工艺进行这种互相捻绕，所以形成六角形网状物112。
图2是链环网状物200的一部分的示意图。图2所示的部分具有五根波状或锯齿状的钢丝202、204、206、208和210，它们交替地与左边相邻的钢丝和右边相邻的钢丝交织在一起。
图3示出了用在根据本发明的金属丝网中的双涂层钢丝300的横截面。钢芯302具有锌的中间金属涂层306。脆性的锌铁合金在钢和锌之间形成过渡区304。为了增强与表层聚合物涂层的粘合度，在锌层和表层涂层310之间存在粘合层(底涂料)308。表层涂层310是高密度聚乙烯。
本发明中使用的钢丝可以具有低碳性质或高碳性质。
低碳钢成分具有范围在0.04wt％至0.20wt％之间的碳含量。这种低碳钢的完整成分的示例如下：碳含量0.06wt％，硅含量0.166wt％，铬含量0.042wt％，铜含量0.173wt％，锰含量0.382wt％，钼含量0.013wt％，氮含量0.006wt％，镍含量0.077wt％，磷含量0.007wt％，硫含量0.013wt％。
高碳钢成分碳是具有大于0.60wt％的碳的钢成分，更特别地，其是具有以下项的钢成分(所有的百分比均是重量百分比)：
范围为从0.60wt％至1.20wt％的碳含量(％C)，例如从0.80wt％至1.1wt％；
范围为从0.10wt％至1.0wt％的锰含量(％Mn)，例如从0.20wt％至0.80wt％；
范围为从0.10wt％至1.50wt％的硅含量(％Si)，例如从0.15wt％至0.70wt％；
低于0.03wt％的硫含量(％S)，例如低于0.01wt％；
低于0.03wt％的磷含量(％P)，例如低于0.01wt％。
作为制造根据本发明的金属丝网的示例，从具有合适成分的金属线材开始，将金属线材拉拔直至其期望的最终钢丝直径。
然后，对该已拉拔的钢丝进行热浸镀锌处理，以为芯钢丝提供具有锌铁合金过渡层的锌涂层。
然后，引导已涂覆锌的钢丝通过填充有合适底涂料的镀浴，以增强金属中间涂层和表层聚合物涂层之间的粘合。可替代地，可将底涂料喷涂在已涂覆锌的钢丝上。
最后，可以通过挤出工艺将表层聚合物涂层施加到已涂覆锌的钢丝上。

通过所谓的Furukawa粘合度测试对现有技术中的聚合物涂层和本发明的各种聚合物涂层在钢丝上的粘合度进行测试。参照图4，钢丝400覆盖有聚合物涂层402。保留10mm的长度，将其余聚合物涂层402从钢丝上去除。然后将具有剩余涂层402的钢丝400拉过已校准的开口，以将剩余涂层402剥离。记录下该剥离所需的力。
已经对以下类型的聚合物涂层进行了测试：
1)PVC：现有技术的聚氯乙烯；
2)HDPE：高密度聚乙烯；
3)HDPE A：双峰型高密度聚乙烯，其具有选自丁烷、己烷和辛烷的组中的至少一种共反应物；
4)HDPE B：高密度聚乙烯，其中混合了线性低密度聚乙烯。
测试结果
剥离力的值是五次剥离测试的平均值。
