光敏性微凝胶在光固化电泳涂料中的应用

Application of Photosensitive Microgel in UV Curable Electrodeposition Coatings

将自制的光敏性微凝胶添加到光固化电泳涂料中,以进一步提升光固化电沉积体系的综合性能。研究了光敏性微凝胶添加量对光固化电沉积体系电泳过程、电沉积膜光固化行为、固化膜玻璃化转变温度及机械性能等的影响。研究结果表明:当光敏性微凝胶添加量不大于6%时,光敏性微凝胶的添加并不影响电沉积过程的有效进行,且随着光敏性微凝胶添加量的增大,光固化电泳涂料固化膜的玻璃化转变温度、贮能模量及拉伸强度等性能均得到有效提升。

Photosensitive microgel was added into the title UV curable coatings to enhanee the compre- hensive performance. The effeet of photosensitive microgel dosage on the eleetrodeposition process, U V cu- ring behavior, the glass transition temperature and mechanic properties was investigated. The results showed that the addition of photosensitive microgel would not affect the eleetrodepnsition process of eleetrodeposition coatings when the photosensitive microgel amount was less than 6% , and the glass transition temperature, the storage modulus and tensile strength of UV cured film were enhanced by the increase of photnsensitive mierogel dosage.
