摘　　要：探查了采用B1B2工艺制备的汽车翼子板与机盖搭接处的漆膜出现局部失光的原因,包括膜厚、脱水率、油漆、机器人喷涂参数、喷涂轨迹等。通过加大边缘处刷子的漆液与成型空气流量,改善了漆雾的雾化状态,最终解决了问题。The causes for partial clouding on the coating sprayed by a B1B2 process at the lapped joint of automobile fender and hood were investigated,including film thickness,dehydration rate,paint composition,robot spray parameters,and spray trajectory.The atomization of paint was improved by increasing the paint feeding rate and shaping air flow rate for the atomizing gun spraying the edges,thus the problem was solved.
