Metallocene polyolefin composite asphalt waterproof coiled material
The invention discloses a metallocene polyolefin composite asphalt waterproof coiled material, which is characterized in that SBS modified asphalt is secondarily modified by special semi-crystalline polyolefin formed by copolymerization of ethylene and propylene, so that the seam peel strength and weather resistance of the modified asphalt waterproof coiled material are greatly improved on the basis of keeping the original performance; the building waterproof life is prolonged. Meanwhile, the material modified by the metallocene polyolefin has thermal weldability of a thermoplastic material, and can be constructed by hot air welding. The product not only enhances the bonding strength of the overlap edge to improve the waterproof effect, but also avoids the risk of plenty of asphalt smoke and fire caused by traditional hot melting construction, and is safe and environment-friendly. The multi-layer composite waterproof material is simple in production process, low in cost, excellent in high and low temperature resistance, aging resistance and storage stability, and is a multi-layer composite waterproof material which is excellent in performance and suitable for waterproof engineering of roofs of industrial and civil buildings and buildings such as underground buildings, bridges, parking lots, swimming pools, tunnels and reservoirs.
本发明公开了一种茂金属聚烯烃复合沥青防水卷材，通过一种乙烯和丙烯共聚形成的特殊半结晶聚烯烃对SBS改性沥青进行二次改性，使得被改性的沥青防水卷材在保持原有性能的基础上大幅度提升接缝剥离强度以及耐候性，延长建筑防水寿命。同时，经过茂金属聚烯烃改性后的材料具有热塑性材料的热焊接性，可使用热风焊接进行施工。该产品既增强了搭接边粘接强度以提升防水效果，又避免了传统热熔施工引发的大量沥青烟雾及着火风险，安全环保。本发明生产工艺简单、成本低、高低温、耐老化性能、储存稳定性优异，是适用于工业与民用建筑的屋面及地下、桥梁、停车场、游泳池、隧道、蓄水池等建筑物的防水工程上的一种性能优越的多层复合防水材料。
