防水松套管及使用该松套管的光缆
摘要：
本发明属线缆技术领域，涉及防水松套管，它包含有圆柱形的管壁体、多根光纤，其特征在于管壁体内部空腔中具有防水层，所述防水层由防水涂层和基带体构成，基带层与管壁体粘为一体，防水涂层粘附在基带体上，防水涂层内部形成圆柱形的空腔，光纤位于防水涂层内部形成的圆柱形空腔中；所述管壁体的材料是改性聚丙烯或聚对苯二甲酸丁二醇酯；所述基带层是与管壁体相同的材料；所述了水涂层为特殊的原料。本发明还揭示了使用防水松套管的光缆。本发明具有抗渗水性能更优秀、可靠性更高、更易制造等有益技术效果。
摘要（英）：

The invention belongs to the technical field of cables, and relates to a waterproof loose tube. The waterproof loose tube comprises a cylindrical tube wall body and multiple optical fibers, and is characterized in that a waterproof layer is arranged in an inner cavity of the tube wall body, and comprises a waterproof coating and a base band body, a base band layer is integrally adhered with the tube wall body, the waterproof coating is adhered to the base band body, a cylindrical cavity is formed in the interior of the waterproof coating, and the optical fibers are located in the cylindrical cavity formed in the interior of the waterproof coating; the tube wall body is made from modified polypropylene or polybutylene terephthalate; the material of the base band layer is the same as that of the tube wall body; the water coating adopts a special raw material. The invention further discloses an optical cable using the waterproof loose tube. The waterproof loose tube and the optical cable using the waterproof loose tube have the beneficial technical effects of better water impermeability, higher reliability, easier manufacturing and the like.
