The invention relates to the technological field of cable sheath, in particular to the production method of a water-resistant cable material. The production method comprises the steps of: (1) preparing the filler, (2) adding the base materials and auxiliary materials including the polyvinyl chloride resin, polybutylene terephthalate and polyethylene wax, (3) adding the rubber additives, (4) extruding with the extruder, cooling and granulating. The invention achieves the high strength, excellent stability and great water-resistant property of the cable material through the reasonable control of the mixing ratio and disposal of materials during various processing stages. 本发明涉及电缆护套技术领域，具体地说，公开种耐水型电缆料的生产方法，其包括以下步骤：(1)制备填料，(2)加入基料和辅料，聚氯乙烯树脂、聚对苯二甲酸丁二酯和聚乙烯蜡，(3)加入橡胶助剂、(4)挤出机挤出，然后冷却、造粒。本发明通过对工艺中各个组分在配比、处理等方面的合理控制，可以使得制备出的电缆料抗拉强度高、稳定性好、且具有良好的耐水性能。
