摘　　要：[目的]针对橡胶金属复合制品传统涂装工艺需对橡胶面进行保护、生产效率低的问题,研究热表面湿碰湿涂装工艺,以简化流程、降低成本。[方法]选用来自不同厂家的两种涂装体系,在50~80℃的橡胶金属复合制品表面直接喷涂,对比不同温度下的涂膜外观、附着力和耐盐雾腐蚀性能,以及橡胶的常规力学性能(如拉伸强度、扯断伸长率等)和疲劳性能,并通过实际生产验证工艺稳定性。[结果]两种涂装体系在≤80℃的热表面喷涂时,涂膜附着力达0级,耐盐雾性能合格(1000 h后单边扩蚀宽度≤2 mm),且对橡胶性能无显著影响;相比于传统工艺,湿碰湿涂装的能耗降低40%以上,生产周期缩短30%~40%。[结论]湿碰湿涂装工艺可安全用于橡胶金属复合制品热表面整体喷涂,但需严格控制温度,尤其适用于结构简单或中等复杂度的产品。[Objective]To address the issues of rubber surface protection requirement and low production efficiency in traditional spraying processes for rubber-metal composite products,a wet-on-wet spraying process on heated surface was studied in this study to simplify procedures and reduce cost.[Method]Two coating systems from different manufacturers were used for direct spraying on rubber-metal composite surfaces at 50-80℃.The coating appearance,adhesion,and salt spray corrosion resistance of coatings,as well as the general mechanical properties(i.e.tensile strength and elongation at break)and fatigue performance of rubber were compared.Process stability was verified through actual production.[Result]Both of the coatings sprayed on heated surfaces within 80℃ featured a 0-grade adhesion,qualified salt spray resistance(the single-side spreading width≤2 mm after 1000 hours),and had no significant impact on properties of rubber.Compared with the traditional process,the energy consumption of wet-on-wet spraying was reduced by over 40%,and the production cycle was shortened by 30%-40%.[Conclusion]The wet-on-wet coating process can be safely applied to integrated spraying on heated rubber-metal composite surfaces,though strict temperature control is required,making it particularly suitable for products with simple or moderately complex structures.
