Waterproof roll base material and preparation method thereof
The invention belongs to the technical field of waterproof building materials, and particularly relates to a waterproof roll base material and a preparation method thereof.The waterproof roll base material comprises a base layer and a coating, and the base layer is prepared from, by mass, 50 parts of medium-density metallocene polyethylene, 20-30 parts of ultralow-density metallocene polyethylene, 20-30 parts of high-density polyethylene and 0.5-5 parts of filler; the coating is prepared from the following raw materials in parts by mass: 100 parts of low-density polyethylene, 0.2-0.5 part of a photoinitiator, 1-2 parts of a cross-linking agent, 1-5 parts of a light screening agent, 0.05-0.2 part of an antioxidant and 0.1-0.2 part of an ultraviolet light absorber. The waterproof roll base material has good tensile property, puncture resistance and ultraviolet aging resistance, and the coating and the base layer are not easy to separate.
本发明属于防水建筑材料技术领域，具体涉及一种防水卷材基材及其制备方法，所述防水卷材基材，包括基层和涂层，其中，基层由如下质量份数的原料组成：中密度茂金属聚乙烯50份，超低密度茂金属聚乙烯20~30份，高密度聚乙烯20~30份，填料0.5~5份；涂层由如下质量份数的原料组成：低密度聚乙烯100份，光引发剂0.2~0.5份，交联剂1~2份，光屏蔽剂1~5份，抗氧剂0.05~0.2份，紫外线吸收剂0.1~0.2份。本发明防水卷材基材具有良好的拉伸、耐穿刺、耐紫外老化性能，涂层与基层不易分离。
