摘要;选用溴化丁基橡胶(II)政性EPDM,制得了自魅IIR改性EPDM防水卷材,研究探讨了IR改性对EPDM防水卷
材粘着性的影响。结果表明:EPDM和IR的配比为7030时,制得的IR改性EPDM防水卷材的各项性能指标均满足
CBT18173.1-2012标准的要求;与未改性EPDM防水卷材相比,IR改性FPDM防水卷材达到较高剥离强度的时间更
短,卷材与卷材、卷材与铝板、卷材与水泥砂浆的剥离强度分别提高了33%、45%和25%;热老化处理后,对于IR改性
EPDM防水卷材和未改性EPDM防水卷材来说,卷材与卷材、卷材与水泥砂浆的剥离强度会增大,而卷材与铝板的剥离
强度会减小。

Abstract: Self-adhered brominated moified u l uber(R modified EPDM waterproofing is prepared and the influence of
IIR modification on adhesion of EPDM waterproofing membrane is discussed. The results show that the performance indicators
of IIR modified EPDM waterproofing membrane when the mass ratio of EPDM and IIR is 70: 30 meet requirements of GB/T
18173. 1-2012. Compared with unmodified EPDM membrane, the time to achieve higher peel strengh of IIR modified EPDM
waterproofing membrane is shorter, and the pecl strength of membrane and membrane, membrane and aluminum, membrane
and cement mortar is increased by 3%, 45% and 25 respectively. After heat aging treatment, for IR modified EPDM
waterproofing membrane and unmodified EPDM membrane, the peel strength of membrane and membrane, membrane and
cement mortar is improved, and the peel strength of membrane and aluminum is decrease
