Abstract

The invention relates to thixotropic optical fiber filling paste for a ribbon optical cable, which mainly comprises base oil, an oil separation inhibitor, a pour point depressant, an antioxidant, an organic gelling agent, an inorganic gelling agent and a thixotropic agent. The invention also provides a preparation method for the thixotropic optical fiber filling paste for the ribbon optical cable. The thixotropic optical fiber filling paste for the ribbon optical cable is mainly characterized in that: the thixotropic optical fiber filling paste has excellent colloid stability and oxidation stability, heat resistance, weather resistance, non separation of oil in a system, low acid value, high thixotropic index, high water resistance, no emulsification, good high-temperature trickle-down property, high temperature resistance and low temperature resistance, is mainly used to be filled in a loose tube of the ribbon optical cable so as to prevent water or other fluid from flowing into or moving into the optical cable, and provides excellent effects of resisting water, buffering and the like for the optical cable.

Description

technical field [0001] The invention relates to an optical fiber filling paste for an optical cable and a preparation method thereof, in particular to a thixotropic optical fiber filling paste for a ribbon optical cable and a preparation method thereof. Background technique [0002] With the development of global telecommunication networks towards digitization, broadband, and intelligence, the rapid development of metropolitan area networks and access networks will increase the demand for optical fibers. Ribbon optical cables are widely used due to their high integration of optical fibers and low laying costs. At present, the construction of optical fiber network is gradually shifting from national backbone network to regional network and metropolitan access network. In optical fiber metropolitan area network and access network, due to the large number of connected nodes, it is often necessary to lay a large number of optical cables—with Ribbon optical cable has many advanta...
