摘要
概述运动型多用途汽车(SUV)后背门密封条的使用条件、结构、材料、挤出硫化工艺和性能测试。SUV后背门密封条主要由海绵管、密实胶、骨架、止水唇边、倒齿组成;胶料主体材料多用三元乙丙橡胶,骨架多为双桥冲切钢带;通过骨架加工、胶料/骨架共挤出成型、硫化定型、骨架折断和弯曲成型、喷涂和打码、在线固化和钻孔等工序制备而成;成品需检测挤压力、插入力和拔出力。我国SUV后背门密封条企业应提高定制化研发能力。
This paper summarizes the application conditions, structure, materials, extrusion vulcanization process and performance test of the back door seal of sport utility vehicle （ SUV ） . SUV back door seal consists of sponge tube, solid rubber, skeleton material, lip seal and pawl. The main material of the compound is ethylene-propylene-diene rubber and skeleton material is mostly die cut steel belt. The seal is usually produced through the process flow of skeleton processing, rubber/skeleton co-extrusion, vulcanization molding, skeleton cutting and bending, coating and coding, online curing and drilling. The compression force, insertion force and pull out force of the finished product are measured for quality control purpose. Currently, China＇ s SUV back door seal manufacturers should improve the research and development capabilities for high level of product customization.
