Abstract

一种单组分抗腐蚀速干型环氧树脂涂料组合物，包含环氧树脂和包含环己酮、丁酮和乙酸丁酯的混合物的溶剂，且不含固化剂。将该涂料组合物作为底漆涂覆在金属基材的至少一部分上，面涂层涂覆在该底漆的至少一部分上，以获得一种经涂覆的基材。

Description

单组分高防腐速干环氧涂料组合物 技术领域
本发明涉及一种单组分高防腐速干环氧涂料组合物以及用其涂覆的基材。
背景技术
环氧涂料可广泛用于包括汽车部件、农用机械以及建筑机械等在内的金属表面底涂应用中。典型地，这些环氧涂料是由树脂组分和固化剂组分组成的双组分体系，这两种组分通常在施涂前进行组合。为了提供最佳的涂膜性能，这两种组分必须刚好在施涂之前以适当的共混比例混合。如果使用了不适当的共混比例，则所得涂膜可能显示出过早的生锈、气泡或者其他涂膜不合格类型。这种不合格通常导致高成本地去除不合格的涂层并施加新涂层。此外，这种双组分涂料工艺复杂、所需的固化温度高、固化时间长，因此其不适合不具备烘烤条件且周期紧迫的情况。
因此，目前对能够迅速干燥且性能可比得上双组分环氧体系的单组分环氧树脂涂料组合物存在需求。与需要高温烘烤的普通双组份环氧树脂体系相比较，该单组分环氧体系无需配合固化剂，具有室温下“快干快硬”，与多种基材的强附着性，强防腐性等特点，因此使用快捷方便，提高了整体施工效率。

首先通过溶剂脱脂对表3中所示的各种基材进行表面处理。将本发明的 环氧底漆空气喷涂到各基材上。底漆喷涂5-10分钟后，空气喷涂面涂层(聚氨酯，得自PPG的SPU74822T-Y)。然后将所得涂层在20-25℃干燥7天。该所形成的涂层体系中，底漆厚度为约20-25μm，面涂层厚度约为20-25μm(通过电磁式膜厚计测得)。
对各基材上形成的涂层进行附着性能和耐腐蚀性测试，结果如表3所示。

Figure PCTCN2016082752-appb-000003
由上表2和3中可以看出，该发明环氧底漆无需配合固化剂，具有室温下“快干快硬”，与多种基材的强附着性，强防腐性等特点，柔韧性和硬度、冲击性能与市售产品相当。
3.本发明1K环氧底漆与不同面涂层匹配的性能测量
样板制作条件：
本测试中所用样板为0.8t×70×150mm不锈钢板/铝合金板/冷轧板。首先通过溶剂脱脂对样板进行表面处理。将本发明的环氧底漆空气喷涂到样板上。底漆喷涂5-10分钟后，空气喷涂下表所示的各种面漆。然后将底漆-醇酸面涂层和底漆-聚氨酯面涂层在20-25℃干燥7天，将底漆-氨基面涂层在130℃干燥15分钟，以及将底漆-丙烯酸面涂层在160℃干燥20分钟。在所形成的涂层中，底漆厚度为约20-25μm，各面涂层厚度约为20-25μm(通过电磁式膜厚计测得)。
对各底漆-面涂层系统进行下表所示的各项测试，结果如表4所示。
