摘要： An adhesive tape composition includes a polymer blend comprising at least one EPDM rubber, and preferably three EPDM rubbers in substantially equal amounts, and an adhesive-enhancing polymer selected from the group consisting of polyisoprene, polybutadiene, and ethylene-propylene copolymer and mixtures thereof. The tape adhesive composition further includes at least one tackifying additive compatible with said polymer blend and a sulfur and organic accelerator cure package for said polymer blend, the adhesive composition being devoid of butyl rubber which is found in most other adhesive tape compositions. This composition is seen as providing excellent long-term heat aging, weathering resistance, and low temperature properties as compared to adhesive tape compositions containing butyl rubber. Moreover, the adhesive tape composition provides more surface tack, better "quick-grab", and higher green strength as compared to adhesive tape compositions containing 100 percent EPDM rubber. A method is also provided for covering roofs which includes the step of employing the adhesive tape composition.
摘要翻译： 粘合带组合物包括包含至少一种EPDM橡胶，优选三个基本上相等量的三元乙丙橡胶的聚合物共混物，以及选自聚异戊二烯，聚丁二烯和乙烯 - 丙烯共聚物的粘合剂增强聚合物及其混合物。 胶带粘合剂组合物还包括与所述聚合物共混物相容的至少一种增粘添加剂和用于所述聚合物共混物的硫和有机促进剂固化包，所述粘合剂组合物没有在大多数其它粘合带组合物中存在的丁基橡胶。 与含有丁基橡胶的胶带组合物相比，该组合物被认为是提供优异的长期热老化，耐候性和低温性能。 此外，与含有100％EPDM橡胶的胶带组合物相比，胶带组合物提供更多的表面粘着性，更好的“快速抓取”和更高的生坯强度。 还提供了一种用于覆盖屋顶的方法，其包括使用胶带组合物的步骤。
