Thermoplastic polyolefin waterproof roll as well as preparation method and application thereof
The invention relates to a thermoplastic polyolefin waterproof coiled material and a preparation method and application thereof.The thermoplastic polyolefin waterproof coiled material comprises a waterproof core layer, the waterproof core layer comprises a thermoplastic polyolefin matrix and auxiliaries, and the thermoplastic polyolefin matrix comprises a combination of a low-melt-index ethylene-propylene copolymer and a high-melt-index ethylene-propylene copolymer; the melt index of the low-melt-index ethylene-propylene copolymer under the load condition of 230 DEG C and 2.16 kg is 0.1-2 g/10 min, and the melt index of the high-melt-index ethylene-propylene copolymer under the load condition of 230 DEG C and 2.16 kg is 10-40 g/10 min. According to the embodiment of the invention, the high-melt-index ethylene-propylene copolymer and the low-melt-index ethylene-propylene copolymer are combined for use, so that the prepared waterproof roll has good tensile strength and dimensional stability, the deformation resistance of the waterproof roll is improved, the problems of deformation, cracking and the like of the waterproof roll in a long-time use process are further reduced, and the service life of the waterproof roll is prolonged. The service life and the waterproof effect of the waterproof roll are improved.
本申请涉及一种热塑性聚烯烃防水卷材及其制备方法与应用，热塑性聚烯烃防水卷材包括防水芯层，防水芯层包含热塑性聚烯烃基质和助剂，热塑性聚烯烃基质包括低熔融指数乙烯‑丙烯共聚物和高熔融指数乙烯‑丙烯共聚物的组合；低熔融指数乙烯‑丙烯共聚物在230℃、2.16㎏负载条件下的熔融指数为0.1～2g/10min，高熔融指数乙烯‑丙烯共聚物在230℃、2.16㎏负载条件下的熔融指数为10～40g/10min。本申请实施例通过高熔融指数乙烯‑丙烯共聚物和低熔融指数乙烯‑丙烯共聚物的组合使用，使制得的防水卷材具有良好的拉伸强度和尺寸稳定性，提高防水卷材的抗形变性能，进而减少防水卷材在长时间使用过程中形变、开裂等问题，提高防水卷材的使用寿命和防水效果。
