砂磨机对水性热反射船壳涂料的影响


 摘要:大富翁棋牌游戏研制了一种水性太阳热反射型船壳涂料,考察了不同的基料、相同的隔热和颜基比对涂层耐介质性能的影响。采用光反射率表征了涂料对可见光、红外光的反射性能。结果表明,以水性树脂为成膜基料,以、云母粉、空心陶瓷微珠为隔热功能颜填料,再加上水及助剂等,制备出的涂层与同样体系的溶剂型热反射船壳漆对可见光和近红外光的反射率基本相同。

    表2中PUA801是普通水性聚氨酯树脂,PUA802是有机氟改性水性聚氨酯树脂,PUA803是有机硅改性水性聚氨酯树脂。在相同的试验条件下,801的附着力较好,802和803的附着力较801差一些,802的抗冲击性能较强,与有机氟改性聚氨酯树脂后其整个分子链的柔韧性增强有关,水性聚氨酯树脂涂膜的柔韧性很好。通过控制分子链段中软硬段的比例可以调节涂膜的柔韧性,从而调整水性聚氨酯涂膜的硬度为B~3H。

    水性聚氨酯PUA903和PUD涂膜48h内耐油水混合物的性能是比较优秀的,但是30d后PUD涂膜的耐油水性能下降,用硅烷偶联剂固化的双组分PUA903完好,这说明水性聚氨酯涂膜短时间内可以经受住油水混合物的腐蚀。如果要长时间经受油水混合物的腐蚀,研究发现在涂料中加入dowcoring84,wetlink78和silok412等内交联剂可以提高涂膜的耐油水混合物的能力。因而提高水性聚氨酯涂膜耐油水混合物性能的途径,可以通过提高树脂本身的交联度,以及外加提高交联度的助剂,这2种方法都是可行的。
