铝型材用消光电泳涂料的研究进展

消光电泳涂料的研究重点是降低材料的光泽,并且达到优异的性能。文章主要介绍铝型材消光电泳的特点、消光原理以及各种不同消光手法。电泳涂料为了得到消光的外观,可以通过两种手段获得:物理消光和化学消光。物理消光法主要采取电泳后处理以及在涂料中添加消光剂来达到消光的目的,化学消光法利用树脂之间的性能差异来降低光泽。文章重点阐述了树脂消光法的原理以及在消光电泳涂料中采取的方法,包括溶解性(SP)差异消光法、内微凝胶消光法、固化温度差消光法等,指出消光树脂的研究方向是制备出能够抑制电解气发生的树脂,使阴极消光电泳涂装成为可能。

Progress in Matting Electrophoresis Coating for Aluminum Alloy

Low gloss of the material and excellent performance are fundamental and significant for the matting electrophoretic coating.The characteristics and principle of matting electrophoresis were introduced in this review.Several kinds of methods in extinction have been analyzed.Physical and chemical method are two kinds of means to get low gloss in the electrophoretic coating,the physical way which is mainly achieved by postprocessing and adding matting agent into the coating,and the chemical method which can be obtained by use of the different performance between resins.Further discussion clarifies the major concerns with the principle in resin extinction methods,which include the solubility（SP） differential extinction law,the microgel extinction method,as well as curing temperature differential extinction optical method.The development prospects of matting electrophoretic coating were pointed out that cathode matting electrophoresis coating will be possible by preparation out resins which composition can inhibit the happening of electrolytic gas.
