Abstract

The invention relates to an optical fiber ribbon coating paste used in a band shape optical cable. The paste is mainly composed of a base oil, an oil separation inhibitor, a pour-point depressant, an anti-oxidant, a tackifying lubricant, an organic densifier and a thixotropic agent. The invention also provides a preparation method of the paste. The optical fiber ribbon coating paste is mainly characterized by good colloid stability, oxidation stability, hear resistance and weatherability, free oil separation system, low acid value, large penetration degree, strong clunging, good permeability and low viscosity. The paste can help the optical fiber ribbon of the band shape optical cable always stay at a most stress-free state in the loose cannula and the cable core of the cable.

Description

technical field [0001] The invention relates to an optical fiber ribbon coating paste and a preparation method thereof, in particular to an optical fiber ribbon coating paste for ribbon optical cables and a preparation method thereof. Background technique [0002] With the rapid development of local area networks and optical fiber access networks, the era of high-density optical fiber networks has come, and optical cables with large core counts—ribbon optical cables have been gradually adopted in the construction of communication networks. At present, the construction of optical fiber network is gradually shifting from national backbone network to regional network and metropolitan access network. The rapid development of metropolitan area network and access network will increase the demand for optical fiber. Ribbon optical cable is due to its high integration of optical fiber and low laying cost It will be widely used; due to the particularity of the structure of the ribbon ...
