【摘要】 研究了硅橡胶 /三元乙丙橡胶 (Q/EPDM )配方对泡沫合金的结构、密度、硬度、压缩、拉伸、应力松弛等力学性能的影响规律。研究表明 :EPDM含量增加 ,泡沫合金的硬度、压缩强度、拉伸强度性能提高 ,而压缩永久变形、应力松弛性能下降。更多还原

【Abstract】 The sturcture,density,hardness,compression modulus,tensile strength,stress relaxation,permanent deformation properties of foam fabricated by blending silicone rubber and EPDM were studied.It was showed that the hardness,compression strength,tensile strength improved,and the compression set and stress relaxation decreased with the increasing content of EPDM.更多还原
