Anti-track uvioresistant ADSS optical cable jack material

Abstract

The invention discloses an anti-track uvioresistant ADSS optical cable jack material which comprises the following raw materials by weight part: 65-70 parts of high density polyethylene resins, 15-20 parts of ethylene acrylic copolymers, 9-10 parts of polyethylene grafting materials, 5-6 parts of polydimethylsiloxane, 15-20 parts of magnesium hydrate, 5.0-5.5 parts of carbon black master batches, 0.5-1.0 part of ultraviolet light absorber and 0.5-1.0 part of antioxidant. In a preparation process, the raw materials are put into a high-speed mixing machine and are uniformly mixed, and then are continuously extruded by a double-screw extruder for two times, and are cooled, cut into grains and dried, so that the jack material provided by the invention is acquired; the temperature of the double-screw extruder is at 160-230 DEG C. The anti-track uvioresistant ADSS optical cable jack material can serve as the jack material special for 220KV and above ADSS optical cable, can realize high-altitude suspending remote conveying, can resist corona and electric track, can resist ultraviolet irradiation, can bear the cold environment test under wind, rain, snow and frost environments and has excellent physical and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of optical cable sheath materials, in particular to an anti-tracking and anti-ultraviolet ADSS optical cable sheath material. Background technique [0002] With the proposal of "Broadband China" and "One Belt, One Road" strategies, the development of optical communication networks has been promoted, and the modernization of optical communication in the "Internet +" era has continued to advance, and the application fields of optical cables have become wider and wider. There are more and more varieties and demand, and the corresponding demand for special photoelectric cable sheathing materials is also increasing. [0003] At present, the outer sheath of ordinary photoelectric cables has low hardness, poor flexibility, poor weather resistance, short service life of the product, and obvious disadvantages in use, which cannot meet requirements such as ADSS optical cables, submarine cables, exploration cables, mar...
