两种乙丙橡胶在密封条应用中的性能
|
摘要
采用酚醛树脂硫化体系,研究了生产密封条所用的乙丙橡胶Vistalon 3666、Royalene 694的流变性能、抗塌陷性能及压变性能。结果表明,乙丙橡胶Vistalon 3666、Royalene 694在低剪切频率下的剪切黏度高,挤出密封条的抗塌陷性能好,形状保持率好,在高剪切频率下的剪切黏度低,挤出成型性能好,可快速实现混炼和硫化,在密封条生产过程中具有易加工的特性。
The rheological properties,collapse resistance and compressive properties of EPDM Vistalon 3666 and Royalene 694 used in sealing strip production were studied by using phenolic resin vulcanization system.The results showed that,Vistalon 3666 and Royalene 694 had high shear viscosity at low shear frequency,and the extrusion sealing strip had good collapse resistance and shape retention rate.At high shear frequency,the EPDM gave low shear viscosity and good machining fluidity,and the EPDM achieved rapid mixing and extrusion easily,and the EPDM exhibited obvious advantages in producing sealing strips.
