Adhesive compositions for bonding EPDM elastomers comprise (a) a neutralized sulfonated EPDM elastomeric terpolymer; (b) an organic hydrocarbon solvent; (c) an ionic plasticizer or mixture of ionic plasticizers; (d) a phenolic hydrocarbon resin or mixture of phenolic hydrocarbon resins and (e) a material selected from mineral oils, petroleum oils, potybutenes, polyisobutylenes and ethylene/propylene copolymers. Such adhesive compositions are particularly suitable for bonding sheets of black EPDM, especially sheets of cured black EPDM, elastomeric membranes together and may also be utilized to bond sheets of cured black EPDM to other uncured elastomers and to non-elastomeric substrates as well.
The adhesive compositions by proper selection of the component (e) material and the addition of a color pigment or dye thereto may also be used to bond colored EPDM elastomers such as white, blue, yellow, green, etc.
An adhesive composition for bonding sheets of EPDM elastomeric roofing membrane in cases where the membrane is to be anchored to the roof surface by mechanical systems will further contain a hydrophobic silica.
用于粘合三元乙丙橡胶弹性体的粘合剂组合物包括:(a) 中和磺化三元乙丙橡胶弹性体三元共聚物;(b) 有机烃溶剂;(c) 离子增塑剂或离子增塑剂混合物;(d) 酚醛烃树脂或酚醛烃树脂混合物和 (e) 选自矿物油、石油油、丁烯、聚异丁烯和乙烯/丙烯共聚物的材料。这种粘合剂组合物特别适用于将黑色三元乙丙橡胶片材,尤其是固化黑色三元乙丙橡胶片材和弹性膜粘合在一起,也可用于将固化黑色三元乙丙橡胶片材粘合到其他未固化弹性体和非弹性基材上。
通过适当选择成分(e)材料和添加彩色颜料或染料,粘合剂组合物还可用于粘合彩色三元乙丙橡胶弹性体,如白色、蓝色、黄色、绿色等。
在通过机械系统将三元乙丙橡胶弹性屋顶膜锚固到屋顶表面的情况下,用于粘接三元乙丙橡胶弹性屋顶膜片材的粘合剂组合物还将进一步含有疏水性二氧化硅。
