改性沥青预铺防水卷材Modified bituminous pre-applied waterproof sheet materials
执行标准:
本产品是以石油沥青为基料，苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）、丁苯橡胶（SBR）、增粘树脂为改性剂，聚酯胎基布为加强层，上表面覆以防（减）粘保护层，下表面覆以聚乙烯膜(PE)或涂硅隔离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.

产品特点
1、耐穿刺、耐硌破、耐撕裂；
2、抗拉强度高，延伸率大，对基层收缩变形和开裂的适应能力强；
3、良好的高低温性能、持久的粘结性；
4、对于基层要求不高，尤其适用于雨季较长、潮湿环境下的防水施工；
5、卷材铺设完后可直接在上部绑扎钢筋，不需要打保护层，缩短工期；
6、相比于高分子自粘胶膜预铺防水卷材更适用于冬季施工，不受低温环境施工限制。
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.
