一种高强度耐磨损青铜雕塑超疏水防腐涂料及其制备方法
技术领域
本发明涉及青铜雕塑防腐技术领域，尤其涉及一种高强度耐磨损青铜雕塑超疏水防腐涂料及其制备方法。
背景技术
雕塑是中国文化的重要组成部分，而青铜雕塑是最主要的雕塑表现形式之一，具有极高的艺术价值。青铜是一种合金，具有硬度高，可塑性好，色泽光亮和耐磨性能好的特点。然而，长期暴露在大气中或者长期处于空气湿度大的情况下，青铜的表面会生成各种锈层，甚至在一定条件下，还会不断向深层腐蚀，直到溃烂穿孔，影响青铜制品的品质甚至寿命。因此，为保证青铜雕塑的外观效果和使用寿命，有必要对其进行表面防护。
近年来，超疏水技术由于在金属腐蚀防护中优异的性能而得到了较多的关注，其主要面临的问题有成本高、制作工艺复杂等。专利200810061480.7以二氧化硅颗粒、硅烷偶联剂、疏水剂和环氧树脂为主要原料制得有机-无机杂化环氧树脂超疏水涂层，具有优良的超疏水性和自清洁性，而且成本低、工艺简单，适合大规模、大面积应用。然而，这种方法得到的超疏水表面稳定性较差，在受热、户外应用时容易失去疏水性，并且在涂层抗裂性、耐损伤性等方面也存在一定的不足，难以将其直接应用于青铜雕塑表面防腐处理领域。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种防腐性能优异、涂层稳定性好、疏水效果持久、耐久性高的高强度耐磨损青铜雕塑超疏水防腐涂料及其制备方法。
本发明是通过以下技术方案实现的：
一种高强度耐磨损青铜雕塑超疏水防腐涂料，其是由下述重量份的原料制得：
EP-44水性环氧树脂乳液40-60，苯并三氮唑0.1-0.15，介孔二氧化硅空心球3-5，巴西棕榈蜡乳液1-2，甲基三甲氧基硅烷2-4，硅烷偶联剂KH-560 0.5-1，钛酸钾晶须1-2，纳米氮化硼0.5-1，异丙醇6-8，失水山梨醇单油酸酯0.1-0.2，妥尔油0.3-0.5；
所述的介孔二氧化硅空心球粒径为1.0-1.5μm。
一种高强度耐磨损青铜雕塑超疏水防腐涂料的制备方法，包括以下步骤：
（1）将介孔二氧化硅空心球按固液重量比1：10-1：15均匀分散于无水乙醇中，然后加入苯并三氮唑常温搅拌12-24h，干燥完全后得复合粉体；
（2）将甲基三甲氧基硅烷和硅烷偶联剂KH-560混合后加入1/3-1/2重量的异丙醇，先滴加0.3-0.5mL冰醋酸并于55-65℃先搅拌0.5-1h，然后静置5-10h，再加入余量的异丙醇、钛酸钾晶须和（1）中的复合粉体，搅拌均匀后滴加10-15mL 20-25%氨水溶液于55-65℃下搅拌2-4h，用醋酸溶液将pH调至中性，得复合溶胶；
（3）将（2）中的复合溶胶与其余原料混合研磨均匀，即得高强度耐磨损青铜雕塑超疏水防腐涂料。
本发明的优点是：
本发明先利用介孔二氧化硅空心球对缓蚀剂苯并三氮唑进行负载，然后与钛酸钾晶须、甲基三甲氧基硅烷和硅烷偶联剂KH-560共混水解缩聚得到聚硅氧烷-二氧化硅、聚硅氧烷-钛酸钾复合微粒，然后与水性环氧树脂乳液、纳米氮化硼等原料混合得到超疏水涂料，能在青铜基体表面形成具有高稳定性的超疏水涂层，兼具防腐性能优异，涂层稳定性好，疏水效果持久的特点，强度高、耐磨损性能好，使用寿命长。
