Low-temperature-resistant waterproof coiled material and preparation method thereof
The invention discloses a low-temperature-resistant waterproof coiled material, which belongs to the technical field of waterproof coiled material preparation. Thelow-temperature-resistant waterproof coiled material is prepared from the following raw materials by weight: 30-50 parts of matrix asphalt, 5-10 parts of EVA resin, 5-10 parts of PE resin, 2 parts of plasticizing filler, 2-4 parts of nitrile rubber, 5-8 parts of processing agent, 10-15 parts of light calcium carbonate, 7.1-7.5 parts of accelerator, and 1-2 parts of anti-aging agent. The invention also discloses a preparation method of the low-temperature-resistant waterproof coiled material, which comprises the following steps of uniformly mixing the raw materials in parts by weight, melting by an extruder, extruding from a T-shaped die head, calendering into a sheet by a three-roller calender, cooling, cutting edges, drawing and rolling to obtain the low-temperature-resistant waterproof coiled material. The intermediate product 3 is grafted on the surface of the modified tourmaline negative ion powder to obtain a plasticized filler, so that the dispersity of the tourmaline negative ion powder in a polymer matrix is improved, the thermodynamic stability of the asphalt material is enhanced, and the asphalt material has good cold resistance.
本发明公开了一种耐低温防水卷材，属于防水卷材制备技术领域，包括以下重量份原料：基质沥青30‑50份、EVA树脂5‑10份、PE树脂5‑10份、增塑填料2份、丁腈橡胶2‑4份、加工助剂5‑8份、轻质碳酸钙10‑15份、促进剂7.1‑7.5份、防老剂1‑2份；本发明还公开了该耐低温防水卷材的制备方法，将各重量份原料混合均匀，然后经挤出机熔融后从T型模头挤出，通过三辊压光机压延成片材，再经冷却、裁边、牵引、收卷，得到耐低温防水卷材，将中间产物3接枝于改性电气石负离子粉表面得到增塑填料，提高电气石负离子粉在聚合物基质中的分散性，有助于增强沥青材料的热力学稳定性，具有良好的耐寒性能。
