- 摘要:
- 为了提高水性丙烯酸树脂涂层的耐腐蚀性能，加入磷酸二氢铵改变其耐腐蚀性能。采用扫描电镜、耐盐雾测试与电化学工作站等对加入不同质量磷酸二氢铵的水性丙烯酸树脂涂层进行测试，通过观察涂层微观形貌并对比耐腐蚀时间、腐蚀电位和腐蚀电流的方法确定磷酸二氢铵的用量。结果表明，当磷酸二氢铵为丙烯酸树脂乳液质量的0.15%时，涂层组织结构最为紧密，耐腐蚀涂层的腐蚀电位为-1.0649 V，腐蚀电流为1.293 μA，耐盐雾时间可达110 h，极化电阻为7.506 kΩ。
- Abstract:
- In order to improve the corrosion resistance of the aqueous acrylic resin coating, ammonium dihydrogen phosphate was added to change its corrosion resistance. Scanning electron microscope, salt spray resistance test and electrochemical workstation were used to test the water-borne acrylic resin coating with different quality of ammonium dihydrogen phosphate, and the amount of ammonium dihydrogen phosphate was determined by observing the coating microstructure, corrosion resistance time, corrosion potential and corrosion current comparison. The results showed that when the ammonium dihydrogen phosphate was 0.15% of the mass of the acrylic resin emulsion, the coating structure was the closest. And the corrosion potential of the corrosion coating was －1.0649 V, the corrosion current was 1.293 μA, the salt spray resistance time can reach 110 h, and the polarization resistance can reach 7.506 kΩ.
