Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a special environment-friendly polymer material for optical cables and a preparation method thereof. Background technique [0002] With the rapid development of society, people are increasingly dependent on communication networks and information transmission, and communication networks are developing towards large capacity and high density. As a common large-capacity communication medium, optical cable plays an increasingly important role in people's daily life, and is an indispensable engineering material in modernization and informationization. [0003] The sheath is an important part of the optical cable. It is a material that is placed outside the optical cable to protect the optical cable. Its performance directly affects the information transmission effect of the optical cable and the service life of the optical cable. Due to the wide range of use of optical cabl...
