Formulation Design and Production Process of Environment-friendly Low-odor Sealing Strip for Passenger Vehicle

介绍乘用车用环保低气味密封条的配方设计和生产工艺。配方采用低气味和环保性好的原材料,如三元乙丙橡胶(EPDM)13561C和EPDM6470C、石蜡油25110、促进剂RATTEN LS-50、促进剂X和发泡剂OBSH;设定合理的混炼和挤出工艺,使小分子有机物充分挥发;采用专用环保混炼胶生产线和挤出生产线或生产前用环保胶料洗车,此条件下制备的密封条气味性能满足汽车企业要求,物理性能满足国家标准要求。

The formulation design and production process of environment-friendly low-odor sealing strip for passenger vehicle were introduced.The formulation used raw materials with low odor and good environmental performance,such as EPDM13561C and EPDM6470C,paraffin oil 25110,accelerator RATTEN LS-50,accelerator X and foaming agent OBSH,and reasonable mixing and extrusion process were set up to make small molecular organics volatilize fully.Special environment-friendly mixing production line and extrusion production line or machine washing with environment-friendly compound before production were adopted,under these conditions the odor property of sealing strip met the requirements of automobile enterprises and the physical properties met the requirement of national standards.
