摘要
汽车风挡玻璃的装配效果直接影响整车质量,因此提高风挡玻璃胶粘剂在装配过程中的粘接力十分重要。文章介绍了聚氨酯(PU)胶粘剂的应用现状、使用PU胶粘剂的优点及玻璃底涂工艺分配不合理存在的质量隐患,提出可通过将刷涂车身底涂与玻璃装配之间的工位设计为2个,来缩短装配时间,对防止风挡玻璃出现开胶、渗水及脱落具有良好的效果。该工艺设计可以有效提高PU玻璃胶粘剂的粘接力,延长汽车风挡玻璃的使用寿命。
Assembly quality of automotive windshield directly affects the vehicle quality, improving the bonding of adhesive in assembly is very important. This paper introduces the application of PU adhesive. PU adhesive advantages and unreasonable process problems about base coating, and the number of workiug position is controlled to 2 between hody base coating working position and glass assembly posilion, ill order to reduce tile assembly time. 2 working positions design has better effect on preventing windshield from unstuck, leakage and peeling. This design can enhance the bonding of PU adhesive, prolong the life of windshicld.
