本发明属于金属材料表面处理技术领域，公开了一种渔光互补型锌铝镁镀层光伏支架用耐水抗菌涂料及其制备方法和应用。该耐水抗菌涂料以重量百分比计算，包括50‑70份的苯乙烯‑丙烯酸丁酯‑季铵盐改性丙烯酸酯共聚物，5‑10份的增粘树脂，3‑4份的增塑剂，100份水溶剂，10‑20份树脂溶剂。该有机涂料由甲基丙烯酸2‑二甲基氨基乙酯、丙烯酸丁酯、苯乙烯含双键的单体聚合而成，这种聚合而成的涂料不仅环保，与镀层结合性强，还具有优异的耐候性、耐水、耐腐蚀性和机械强度，由于抗菌官能团以共价键形式与有机树脂网络结合，因此使得钢板涂层自身具有长效，固有的抗菌特性。
Description
技术领域
本发明属于金属材料表面处理技术领域，涉及一种渔光互补型锌铝镁镀层光伏支架用耐水抗菌涂料及其制备方法和应用，在镀层表面制备优异的耐水性和抗菌性能的涂层。
背景技术
光伏支架是太阳能光伏电站的基础结构，主要包括地面光伏电站支架，漂浮光伏面板支架，棚式光伏面板支架和屋面光伏面板支架。其中漂浮光伏面板支架一般建设在湖泊，水库，池塘等水位落差小，水流速度慢，距离农村较近的水域。这种漂浮式光伏电站不占据土地资源，在发电的同时为下方池塘的鱼虾提供遮挡，对水体有良好的冷却效果。在发电的同时促进了养殖业和旅游产业，是国内外光伏电站的热门发展方向。
由于光伏电站所处的沙漠、滩涂、戈壁等地区环境恶劣的情况，具有优良耐蚀性的锌铝镁镀层材料有望被大量应用到光伏支架的制作中。其中渔光互补型光伏电站支撑结构件需要能够承受风、雨、水流等各种恶劣天气的长期作用；湖泊，水库鱼塘等水域为细菌等微生物的生长和复制提供了合适的生长条件。因此要求光伏支架需要能够长期耐受微生物、有害化学物质侵蚀、酸碱性水质等各种复杂水质环境，并与生态环境相协调，不析出有害化学物质；需能够适应循环往复的波浪及水流荷载作用，不产生疲劳应力破坏。
由于锌铝镁合金镀层表面有大量的Al、Mg活性元素，应用在渔光互补型光伏支架中在复杂的水质环境中极易发生氧化锈蚀现象。为提高锌铝镁合金镀层钢板在水域***的耐蚀性和抗菌性需进行表面防腐处理。中国在锌铝镁镀层钢板方面开发较晚，尚未在锌铝镁镀层在湖泊水库等恶劣环境下的锌铝镁镀层表面防腐抗菌性能开展研究，与日本等国家技术差距较大。
专利CN 110760833A提供了一种高效抗菌钝化镀锌钢板。抗菌液包括三价铬钝化液以及抗菌纳米颗粒。抗菌纳米颗粒粒径小于30nm，添加的质量分数占三价铬钝化液重量的1-5％,通过在热辐射烘箱中以80-100℃烘烤5-20s，风冷后在40℃以下卷取以免钝化层之间发生粘接。该抗菌钝化膜制备方法简单，结构简单，抗菌性，耐蚀性强，适合批量生产工艺。
专利CN 110102142B提供了一种抗菌净化彩涂板的制造方法。首先将彩色涂层钢板表面通过喷砂、火焰、等离子等活化处理备用，其次在预处理彩涂板表面喷涂硅烷偶联剂接枝剂，最后将银掺杂或钨掺杂的纳米二氧化钛抗菌溶液通过偶联的方法喷涂在活化后的彩涂钢板表面，喷涂量2g/m2，120℃保温30min固化抗菌涂层。该方法制备的抗菌彩色涂层钢板具有持久抗菌功效，同时改善使用环境，提高人们的生活品质。
专利CN 105688278B提供钛种植体表面制备抗菌涂层的方法，该抗菌涂层是通过将在氢氧化钠溶液浸泡24h的钛片交替浸泡在聚阳离子溶液如壳聚糖、聚赖氨酸溶液和聚阴离子溶液例如质酸、海藻酸钠、聚谷氨酸等溶液中，交替浸泡三次，浸泡时间10s，最后将处理过的钛片浸泡硝酸银溶液0.5-2h，再浸泡0.1-0.5mol/L抗坏血酸溶液0.5-2h。这种通过层层自主装方式可以制备出具有良好生物相容性和抗菌性的钛表面涂层。
专利CN 105316669B提供了一种不锈钢抗菌钝化液及其制备方法，以重量份计，包括以下组分：γ-甲基丙烯酰氧基三甲氧基硅烷10-20份，1,2-双(三乙氧基硅基)乙烷10-20份，羟丙基甲基纤维素5-10份，氨基甲酸酯5-15份，羟丙基壳聚糖5-10份，纳米氧化钛2-5份，柠檬酸10-15份，钼酸钠5-15份，硅酸钠5-10份，去离子水50-80份。该钝化层与不锈钢基附着力强，具有优异的耐蚀性和光催化抗菌性和自修复性。
专利CN103382346B提供了一种蒸汽管道用耐高温耐水涂料及制备方法，该涂料以质量份计含有以下成分：硼酚醛树脂20～30份，水玻璃15～25份，滑石粉2.5～5份，霞石3～6份，碳酸钙0.8～1.6份，氧化钛2～4.5份，氧化铁红4～6份，三聚磷酸钠1.55～2.55份，亚铁盐0.2～1.2份，己二酸丙二醇聚酯0.05～0.15份，羟乙基纤维素0.4～0.65份，防霉剂0.13～0.25份，安息香0.3～0.4份，水30～40份。该耐高温涂料可以承受800-1000℃的高温，耐水耐腐蚀，能延长蒸汽管道使用寿命。
专利CN104263162B提供了一种船体甲板用耐水涂料及其制备方法，包含成膜剂丙烯酸锌树脂15-30％，增粘剂酚醛树脂15-30％，增塑剂邻苯二甲酸二异辛酯3-8％，阻燃剂聚四氟乙烯粉、氯化石蜡4-8％，阻隔剂氧化铁红、滑石粉、硫酸钡、二硫化钼等累计22-50％，溶剂煤焦油、甲基吡咯烷酮2-5.5％。该涂料具有优异的耐水、耐大气老化、耐磨耐腐蚀，能长效保护船体甲板。
专利CN 113136003A提供一种含噻唑结构的抗菌苯丙乳液及其制备方法和应用，包含乳液聚合单体苯乙烯75-108份、丙烯酸丁酯125-180份、甲基丙烯酸3-25份、噻唑结构的丙烯酸酯25-100份、乳化剂8-55份、引发剂1-6份和去离子水。通过乳液聚合法制备抗菌性能的苯丙乳液，该乳液具有优异的耐水性、耐碱性、耐擦洗和附着性，由于聚合物本身抗菌，与无机添加抗菌剂和有机小分子抗菌剂添加剂相比，该苯丙乳液可以用来制备具有持久抗菌性能的乳胶漆。
发明内容
本发明为一种渔光互补锌铝镁镀层钢板表面抗菌涂层，有机涂层网络由甲基丙烯酸2-二甲基氨基乙酯、丙烯酸丁酯、苯乙烯含双键的单体聚合而成，这种聚合而成的涂层不仅环保，与镀层结合性强，还具有优异的耐候性、耐水、耐腐蚀性和机械强度，由于抗菌官能团以共价键形式与有机树脂网络结合，因此使得涂层自身具有长效，固有的抗菌特性。避免了传统的通过载药或添加抗菌纳米颗粒的方式，抗菌时效短，载药效率低，抗菌纳米颗粒或者药物无法迁移到聚合物表面达到抗菌效果，同时在使用过程中释放后逐渐丧失抗菌性等缺点。
为实现上述目的，本发明提供一种渔光互补型锌铝镁镀层光伏支架用耐水抗菌涂料。述耐水抗菌涂料以重量份计算，包括50-70份的苯乙烯-丙烯酸丁酯-季铵盐改性丙烯酸酯共聚物，5-10份的增粘树脂，3-4份的增塑剂，100份水溶剂，10-20份树脂溶剂。

进一步地，在上述技术方案中，所述步骤2中S1的搅拌温度为25～35℃，转速为150～200r/min。所述步骤2的S1中乳化剂为水包油O/W型烷基酚聚氧乙烯醚如OP-4、OP-7、OP-10、OP-50或吐温20、吐温40、吐温60、吐温80等其中一种，优先选择吐温80。所述S1中阳离子乳化剂为十二烷基氯化铵、十六烷基三甲基溴化铵、十六烷基溴化吡啶等，优先选择十六烷基三甲基溴化铵(CTAB)该乳化剂能有效抑制改性后的带正电密集型树脂无法乳化，会发生聚集沉淀的问题，能有效促进抗菌树脂在涂料中的均匀混合。所述步骤2中S2的所述S2整个反应过程中转速为230～270r/min。所述步骤2中S2的引发剂为自由基引发剂如偶氮二异丁腈(AIBN)、偶氮二异庚腈、过氧苯甲酰(BPO)；或过硫酸盐如过硫酸钠、过硫酸铵、过硫酸钾等其中一种。优先选择引发活性较高的过氧苯甲酰。过氧苯甲酰水溶液的质量浓度为0.5～1％；步骤2中S2的中的过滤网为150目不锈钢过滤网。
