Abstract: Siloxane fluoride is aded as hydrophilic aditive to provide a hydrophilic surface of FEVE fluorocarbon paint film，so that the ability of self-cleanlines and contamination resistance of paint film is improved.Surface elements and water contact angle of paint films were characterized by using XPS and con-tact angle apparatus.The experimental results show that the hydrophilic aditive evidently acumulates on the surface of paint films，and hydrolyzed rapidly to produce hydrophilic groups，forming a stable hydrophlic surface with a water contact angle below35°.

Key words: FEVE fluorocarbon paint, hydrophilic additive, contact angle, XPS

摘要： 通过添加氟化硅氧烷亲水化剂使 FEVE氟碳漆膜表面产生亲水性，从而提高涂膜的自洁性和耐沾污性。 采用光电子能谱(XPS)、接触角测定仪对漆膜表面元素和与水接触角进行表征。实验结果表明，亲水化剂在漆膜表面 明显富集，并且在较短时间内水解形成亲水化基团，获得了稳定的亲水性，漆膜表面与水接触角维持在 35°以下。
