不饱和脂肪酸改性甲基丙烯酸聚酯纳米乳液合成

Synthesis of Methylacrylic Acid Polyester Nanoemulsion

在不使用乳化剂的情况下,利用分子自组装聚合技术制备了不饱和脂肪酸改性甲基丙烯酸聚酯纳米乳液,对聚合物的粒径用透射电镜(CENT)方法进行了测量,其粒径为100 nm。试验结果表明,用它制成了水性嵌段型纳米结构外墙漆,其耐洗刷性等性能有很大提高,可以达到10000次以上。

A new type of polymer nanoemulsion has been synthesized by molecular self-assembly technique. The emulsion particle size that can be clearly observed by CENT is less than 100 nm. The results of these measurements support the idea that polyacrylate molecular segments assemble with polyester segments. Then based on the polymer nanoemulsion, waterborne block type exterior architectural nanopaints have been prepared. The waterborne coatings behave good water-resistance, physics-mechanical properties and decorative and protective performance. Scrub resistance improves greatly which can reach 10000 times.
