改性瀝青預鋪防水卷材Modified bituminous pre-applied waterproof sheet materials
執行標準:
本產品是以石油瀝青為基料，苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）、丁苯橡膠（SBR）、增粘樹脂為改性劑，聚酯胎基布為加強層，上表面覆以防（減）粘保護層，下表面覆以聚乙烯膜(PE)或涂硅隔離膜所制成的防水卷材。
The product is a kind of self-adhesive sheet waterproof materials using styrene-butadiene-styrene (SBS), styrene butadiene rubber (SBR) modified bitumen and tackifying resin as dipping and coating material, and the reinforcement layer is based on polyester felt, with the upper surface covered by reactive fine sand as anti-sticking protective layer, the lower surface covered by silicon-coated isolation film.

產品特點
1、耐穿刺、耐硌破、耐撕裂；
2、抗拉強度高，延伸率大，對基層收縮變形和開裂的適應能力強；
3、良好的高低溫性能、持久的粘結性；
4、對于基層要求不高，尤其適用于雨季較長、潮濕環境下的防水施工；
5、卷材鋪設完后可直接在上部綁扎鋼筋，不需要打保護層，縮短工期；
6、相比于高分子自粘膠膜預鋪防水卷材更適用于冬季施工，不受低溫環境施工限制。
1. It can form a high strength waterproof layer by performance of resistance to water, puncture, breaking, and tearing.
2. High tensile strength, high elongation, good adaptability to shrinkage deformation and cracking of the substratum.
3. Good temperature resistance is suitable for cold and hot regions, and the long-lasting adhesion can keep waterproof function permanently.
4. The pre-installation do not need the primer, especially is suitable for engineering with wet substratum because of wet season.
5. Rebar binding can be operated straightly after waterproof sheet installation, which can save the concrete protective cover and reduce the construction period.
6. Compare to high density polyethylene self-adhesive waterproof sheet for pre-installation, the product can be applied in low-temperature environment, which is more suitable for winter construction.
