Preparation method of deep sea cable filling strip

Abstract

A preparation method of a deep sea cable filling strip relates to a preparation method of a conductor filling strip. The preparation method comprises the following process steps: mixing rubber, a vulcanizing agent, a vulcanization accelerator, an antiager, a plasticizer, a reinforcing filler and a tackifier in parts by weight; and then calendering, slitting and packaging to obtain the finished product. The method has a simple production technology, stable technical properties and high practicability; the product is used in the cable and the cable core of the optical cable, the product has high strength, uniform thickness and a good saturated water absorption effect and has the functions of shielding and buffering the electric field; and the product also has viscoelasticity, thus the filling cable core is stronger and the service life of the optical cable can be prolonged.

Description

technical field

[0001] The invention relates to a preparation method of a conductor filling tape, in particular to a preparation method of a cable filling tape in a deep-sea high voltage state. Background technique

[0002] With the development of science and technology, water-blocking materials for optical cables are constantly updated and improved. At present, there are two main categories: one is ointment; the other is water-blocking tape and water-blocking yarn series. The two types of materials are different in technology, but both can achieve the purpose of moisture resistance and water resistance. However, the ointment filling process is complex, polluting, and prone to degradation reactions to plastics. The water-blocking tape and water-blocking yarn series are wrapped on the outside of the cable core. When moisture or water invades, it can quickly absorb water and expand rapidly. However, due to the use of non-woven fabrics and fiber yarns as the base material, t...
