一种电缆用阻水带
摘要：
本发明公开了一种电缆用阻水带，包括：基材层、压合在所述基材层上下两面的隔水层、和附着在所述隔水层外表面的防水层，所述基材层采用玻璃纤维制成的，所述隔水层是由高吸水性树脂制成的，所述防水层为聚氨酯薄膜，所述玻璃纤维的组分和各组分的质量配比为：石英砂50%-55%、白云石25%-30%、硼酸5%-10%和氧化铝10%-15%。通过上述方式，本发明采用多层复合结构，成本低，具有良好的阻水性和耐酸碱性。
摘要（英）：

The invention discloses a water-blocking belt for a cable. The water-blocking belt comprises a base material layer, water-blocking layers pressed on the upper side and the lower side of the base material layer, and waterproof layers attached to the outer surfaces of the water-blocking layers. The base material layer is made of glass fiber, the water-blocking layers are made of high water-absorbent resin, the waterproof layers are made of polyurethane films, and the glass fiber comprises, by weight, 50-55% of quartz sand, 25-30% of dolomite, 5-10% of boric acid and 10-15% of aluminum oxide. By means of the mode, the water-blocking belt is of a multi-layer composite structure, cost is low, and the water-blocking belt has good watertightness and acid and alkali resistance.
