具有优异耐候性、 耐蚀性和耐碱性的热镀铝锌钢板及其制备方法和表面处 理剂
技术领域
本发明属于金属材料表面处理领域, 涉及一种具有优异耐候性、 耐蚀性和 耐碱性的镀铝锌钢板及其制备方法和表面处理剂。 背景技术
鉴于热镀铝锌钢板具有良好的耐腐蚀性、 高热反射性、 耐热性及外观装饰 性等特点, 其被广泛用于建筑、 家电、 汽车等国民生活的各个领域; 例如建筑 行业的轻钢结构之屋顶与墙面、 檩条、 楼承板、 护栏、 音障和排水装置等, 家 电领域大型电器背板、 汽车排气系统等。 特别在用作建筑材料使用时, 由于要 保证十几年甚至几十年的使用寿命要求,对热镀铝锌钢板提出较为严格的要求: 如屋顶及墙面用材需具备良好的耐候及耐蚀性能, 保证钢板服役过程外观表面 不变色, 不腐蚀, 长时间维持美丽的外观; 用作楼承板、 护栏及排水装置等材 料使用时, 常常要要与石板瓦、 混凝土等接触而暴露于碱性腐蚀环境下, 此时 则必须要求材料具备良好的耐碱性能等。
为应对上述要求及期望, 通常会对热镀铝锌钢板表面进行湿法涂膜处理, 以增强热镀铝锌钢板对于各种腐蚀介质和环境的抗性, 目前用于热镀铝锌钢板 表面处理剂的类型大致可分为有鉻处理和无铬处理两类。 对于建筑行业来说, 由于目前暂未出台相应的环保法规,且铬酸盐极强的耐腐蚀性和自我修复功能, 使得有铬表面处理的热镀铝锌钢板成为现今建筑行业的主流, 但随着社会的发 展, 环保要求日趋严峻, 建筑行业的环保化已是大势所趋, 因此, 各项抗性优 异的无铬表面处理热镀铝锌钢板将成为未来的主流。
曰本专利 JP2007-321224 中公开了一种具有优异耐蚀性和耐水密着性的热 镀铝锌钢板, 其表面覆盖有无铬处理有机 /无机复合保护膜, 该保护膜含有硅烷 改性的水性阴离子树脂、 四价钒化合物以及磷酸或其化合物等组成。 涂覆有该 保护膜的热镀铝锌钢板具有良好的耐蚀性能及耐水密着性能, 但其没有足够的 耐候性及耐碱性能。
中国专利 CN 1530462A提供了一种用于金属表面用处理剂以及用该处理剂
处理的镀铝锌钢板; 其中该表面处理剂包含具有羧基及酸胺结合的水系树脂, 如尿烷树脂或丙烯酸树脂, 有机硅烷偶联剂以及 1种或 2种金属盐类化合物, 上述处理剂涂覆于钢板表面形成 0.2-5g/m2的单层皮膜。 虽然其提供了一种能形 成具有良好耐蚀性和耐碱性的无鉻涂膜, 但对于耐候性能并未提及。
中国专利 CN1511908A提供了一种用于处理镀有铝-辞合金的钢板的水性树 脂组合物, 其含有阴离子型水分散性聚氨酯树脂、 硅烷偶联剂和水溶性锆化合 物等, 用于该处理剂处理的铝锌合金表面钢板具备高的可被加工处理性、 高耐 蚀性、 防止黑变性能、 耐候性能和对涂膜的附着性能, 并且该处理剂也为环保 型产品, 但该专利对于耐气候性的评价时间仅为 100h, 考核时间较短。
中国专利 CN124777A公开了一种树脂组合物涂覆的铝锌合金钢板,其将有 氨基的硅烷偶联剂、 铬离子、 至少选自有 2-3 碳的三元醇及二元醇中之一的醇 并入含有羧基及缩水甘油基并且酸值为 10-60 的丙烯酸聚合物树脂乳液中, 使 所得混合物的 pH为 7-9以获得该树脂组合物; 并将其涂覆于铝锌合金钢板, 干 燥后以形成树脂皮膜。涂覆有该树脂组合物的铝锌合金钢板具有良好的成型性、 抗腐蚀性、 抗碱性及可涂装性。 但其设计的处理药剂为含铬产品, 不具备环保 性能, 且并未对耐候性进行考察。 发明内容

本发明所提供的制备具有优异耐候性、 耐蚀性和耐碱性的镀铝锌钢板的方 法中, 镀铝锌钢板的干燥温度最好在 80-180。C之间, 如果低于 80。C , 则皮膜交 联不够充分, 可导致皮膜各项性能下降, 如果高于 180°C , 则处理液中部分组 分性能改变, 可影响成膜效果。
本发明的表面处理剂涂覆于镀锌钢板表面所获得的干膜厚度在 1-3 微米之 间, 不到 1微米时, 由于皮膜比较薄, 会导致辊压加工性、 耐蚀性、 耐候性等 的下降; 皮膜超过 3微米时, 会增加单位面积的表面处理成本。
本发明对涂覆于镀铝锌钢板表面的水性表面处理剂的加热干燥方式没有特 别的限制, 可以是热风加热、 感应加热、 红外加热等。 本发明对镀铝锌钢板的 尺寸、 形状等也没有特别的限制。
