摘要

合成了氨基硅油改性丙烯酸酯（AMPA），将其与PTFE微蜡粉、PE改性PTFE微蜡粉作为表面改性剂加入到紫外光（UV）固化涂料中，用红外光谱对固化前后进行了表征，研究了其对UV固化膜耐磨性的影响，考察了固化膜表面元素的富集现象，并测试了固化膜表面水接触角和光泽度的变化。研究结果表明，表面改性剂具有自润滑的作用，少量加入即能显著地提高固化膜的耐磨性，含硅改性丙烯酸酯（AMPA）的质量分数由0.0%增加到1.0%时，光固化膜耐磨测试质量损失由22.8 mg下降到9.2 mg，表面水接触角由43.3°增加到100.3°，表面光泽度由113.5°下降到95.5°。

Abstract

Amido modified polyorganosiloxane acrylate (AMPA) was synthesized. A series of UV-curable coatings were prepared by using amido modified polyorganosiloxane acrylate (AMPA), PTFE micro-wax powder or PE modified PTFE micro-wax powder as surface modifiers. The UV-cured process was characterized by means of FT-IR measurements. The wear resistance, surface elements, water contact angle and gloss of UV-curable films were investigated. The results show that these surface modifiers have self-lubricating action, and small content (0.5%—2%) causes significant increment of wear resistance of cured coatings. When the mass content of amido modified polyorganosiloxane acrylate (AMPA) changes from 0.0% to 1.0%, the mass loss of wear resistance measurements of UV-cured films decreases from 22.8mg to 9.2 mg and water contact angle increases from 43.3° to 100.3°, but the gloss of UV-cured films decreases from 113.5°to 95.5°.
