Description

一种钇铝石榴石改性铜雕塑用环氧-丙烯酸防腐水性漆及其 制备方法
技术领域
本发明涉及铜雕塑用涂料技术领域，尤其涉及一种钇铝石榴石改性铜雕塑用环氧-丙烯酸防腐水性漆及其制备方法。
背景技术
随着现代生活水平和审美意识的提高，雕塑这一传统工艺品受到越来越多的设计师和大众喜爱。其中铜雕塑不仅样式独特，并且具有很高的欣赏价值，与其他材质的雕塑相比，还有坚固耐用、不易破坏的特点，尤其在现代化城市景观建设中，得到广泛的应用。铜雕塑无需频繁地保养和维修，但是在空气湿度过大的条件下使用，尤其是室外的日晒雨淋会严重影响铜雕塑的质量。为减少腐蚀，延长铜雕塑的使用寿命，通常采取的预防性措施是对铜雕塑表面进行防护处理，其中涂刷油漆是目前使用较为广泛、经济实用的方法。
随着环保意识的增强，传统溶剂型防腐漆逐渐被淘汰，高性能、低污染的水性防腐漆已经成为发展趋势。目前应用较多的水性防腐漆主要有环氧树脂等。文献《丙烯酸接枝改性环氧树脂防腐乳液的研究》采用丙烯酸对环氧树脂进行接枝改性，得到的乳液兼具环氧树脂和丙烯酸树脂的优点，具有良好的附着力和耐腐蚀性能。但是，这种方法制得乳液的三维网状结构交联度较低，耐水性不足，对基体表面的防护不够，影响了其防腐性能，且无法应对涂装缺陷或者涂层破坏带来的防腐持久性下降，因此在实际应用中有待进一步改进。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种交联程度高、机械性能好、防护性能强并且具有优良持久性的钇铝石榴石改性铜雕塑用环氧-丙烯酸防腐水性漆及其制备方法。
本发明是通过以下技术方案实现的：
一种钇铝石榴石改性铜雕塑用环氧-丙烯酸防腐水性漆，其是由下述重量份的原料制得：
环氧树脂E-44 40-60，氨基树脂2-4，乙二醇单丁醚10-15，正丁醇15-25，甲基丙烯酸6-8，苯乙烯4-6，丙烯酸丁酯2-4，衣康酸二正丁酯1-2，过氧化苯甲酰0.5-1，N,N-二甲酰基乙醇4-6，纳米氟化铈0.5-1，二氧化钛纳米管3-5，纳米钇铝石榴石粉2-4，苯丙三氮唑0.3-0.5，γ-巯丙基三乙氧基硅烷0.1-0.15，PTFE乳液3-5，水100-120；
所述二氧化钛纳米管是采用水热合成法制得，管径为5-25nm，管长为500-1000nm。
一种钇铝石榴石改性铜雕塑用环氧-丙烯酸防腐水性漆的制备方法，包括以下步骤：
（1）将二氧化钛纳米管按固液重量比1:10-1:15与无水乙醇混合分散均匀，然后加入苯丙三氮唑和γ-巯丙基三乙氧基硅烷搅拌6-12h，离心后将所得固体真空干燥，得改性钛纳米管；
（2）将（1）中的改性钛纳米管、纳米钇铝石榴石粉、纳米氟化铈、N,N-二甲酰基乙醇和水混合分散均匀，得A组分，将环氧树脂E-44、氨基树脂、乙二醇单丁醚和正丁醇混合升温至105-110℃，然后缓慢滴加甲基丙烯酸、苯乙烯、丙烯酸丁酯和过氧化苯甲酰的混合溶液，并于115-120℃保温反应2-4h，得B组分，将A组分和B组分于80-85℃混合并高速搅拌均匀，然后于50-60℃保温反应1-1.5h，得复合乳液；
（3）将（2）中的复合乳液与其余原料混合后研磨均匀，即得钇铝石榴石改性铜雕塑用环氧-丙烯酸防腐水性漆。
本发明的优点是：
本发明先利用二氧化钛纳米管对苯丙三氮唑和γ-巯丙基三乙氧基硅烷进行负载，然后与环氧树脂、氨基树脂和丙烯酸酯进行乳液聚合反应得到复合乳液，既能有效提升涂膜的三维网状结构交联程度，提升对基体的防护性能，又能改善涂膜的机械性能和稳定性，并且由于对复合缓蚀剂的负载，能对涂膜缺陷或者破损处的金属起到良好的防腐蚀作用，提高表面防护的持久性。同时，通过纳米钇铝石榴石粉等原料的添加与复配，使得到的铜雕塑水性漆能为基体表面提供全面、持久的防护，兼具优良的防腐蚀性能、机械性能和持久有效性，硬度高，光泽性好，耐候性强。
