环保黑色水性底面合一用丙烯酸乳液的开发与应用

Development and Application of Acrylic Emulsion with Water Based Black Bottom Coating in Environmental Protection

通过自由基聚合机理合成了一种全新的水性丙烯酸乳液,这种乳液成膜后具有优异的耐冲击性能、抗老化性能、耐水性能、和附着力,将这种乳液应用到黑色水性底面合一涂料中,最终制备出一种具极好好的附着力、优异的耐冲击和弯曲性能、良好的耐水、耐盐雾性能的黑色水性底面合一涂料,并且在国内铁路货车上成功应用,符合环保绿色工业发展的方向。

Through free radical polymerization mechanism, a new kind of water-based acrylic emulsion was synthesized. The emulsion had excellent impact resistance, ageing resistance, water resistance and adhesion after film formation. Applying the emulsion to black bottom and coating, the black water based coating with a very good adhesion, excellent impact resistance, bending resistance, good water resistance and salt fog resistance was prepared. And it was successfully applied in domestic railway wagon, which was in line with the direction of green industry development.
