| Abstract: |
| The work aims to improve edge corrosion of parts. High edge anti-corrosive electrophoretic paint of good hydrophobicity was selected, adding micro gel additive could control film flow, improve inhibition shrinkage phenomenon of electrophoretic paint during drying and curing, increase film thickness and film coverage in workpiece edges, especially sharp edges and welding positions. As a result, salt-spray corrosion resistance was improved significantly. Meanwhile, reasonable coating process was selected to emphatically investigate corrosion resistance of edges, corner angles and welding positions of workpieces made from of different materials, such as blade corroded, casting parts, hot plates, pickling plates and cold plates. Application of high edge anti-corrosive electrophoretic paint with micro gel improved design of electrophoretic paint cationic resin aqueous system system and special micro gel technology, blade corroded part reached to 240 h, and casting parts 480 hours, one-edged corrosion of the workpiece was no more than 2 mm in 1000 h salt spray test, unilateral corrosion, fully meeting the corrosion resistance requirements of automobile parts. Provided that reasonable electrophoretic painting process is selected and coating process management & control on production site is enhanced, salt-spray corrosion resistance of high edge anti-corrosive electrophoretic paint may be up to over 1000h on different materials including hot plates, pickling plates and cold plates, fully meeting corrosion resistance requirements of various workpieces. |
