一种抗冲击青铜雕塑超疏水防腐涂料及其制备方法

Abstract

本发明公开了一种抗冲击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,水性酚醛树脂3‑5,介孔二氧化硅空心球3‑5,甲基三甲氧基硅烷2‑4,硅烷偶联剂KH‑560 0.5‑1,异丙醇6‑8,衣康酸0.1‑0.2,全氟烷基乙基醇0.3‑0.5,纳米玻璃纤维0.5‑1,山梨醇酐油酸酯0.1‑0.15。本发明的防腐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,还有高抗冲击、抗裂性能,耐久性高,使用寿命长。
The invention discloses impact-resistant bronze sculpture super-hydrophobic anticorrosion coating. The impact-resistant bronze sculpture super-hydrophobic anticorrosion coating is prepared from the following raw materials in parts by weight: 40-60 parts of EP-44 waterborne epoxy resin emulsion, 0.1-0.15 part of benzotriazole, 3-5 parts of waterborne phenolic resin, 3-5 parts of mesoporous silicon dioxide hollow spheres, 2-4 parts of methyl trimethoxy silane, 0.5-1 part of a silane coupling agent KH 560, 6-8 parts of isopropanol, 0.1-0.2 part of itaconic acid, 0.3-0.5 part of perfluoroalkyl ethyl alcohol, 0.5-1 part of nano glass fiber and 0.1-0.15 part of sorbitol anhydride oleate. The impact-resistant bronze sculpture super-hydrophobic anticorrosion coating can form a super-hydrophobic coating with high stability on the surface of bronze matrix, has the characteristics of excellent anticorrosion property, good coating stability and lasting hydrophobic effect and also has high impact resistance, high crack resistance, high durability and long service life.
