Problems solved by technology

Because the diameter of the microcable casing is generally in the range of 0.6mm-1.2mm, and the ordinary fiber paste has a high viscosity (poor fluidity) and a small cone penetration value (thick ointment) when filling the microcable casing , prone to clogging, or insufficient uniformity, from the loss of fiber paste to protect the role of the personal guard of the optical fiber

Abstract

The present invention discloses a micro-cable optical fiber filling paste comprises: 70-85 wt% of base oil; 1-8 wt% of solid lubricant; 2-10 wt% of lubrication adhesive compound; 2-10 wt% of thickening agent; 2-10 wt% of oil separation inhibitor; 2-10 wt% of viscosity index improver; and 0.3-1 wt% of anti-oxidant. The present invention also provides a preparation method for the micro-cable optical fiber filling paste. The micro-cable optical fiber filling paste has the advantages of excellent fluidity, lubricity, thixotropy, adhesiveness, temperature toleration, hear resistance and weatherability; non separation of oil in a system; low acid value; large penetration degree; and low viscosity. Therefore, the micro-cable optical fiber in a sleeve and a cable core in the micro-cable always be in a most free and unstressed state, and the optical cable performance is guaranteed for stable and safe transmission for a long time.

Description

technical field [0001] The invention relates to an optical fiber filling paste and a preparation method thereof, in particular to an optical fiber filling paste for micro cables and a preparation method thereof. Background technique [0002] With the rapid development of the optical communication industry, optical fiber gradually reaches buildings, homes, and desktops, and people's study, work, and life will undergo qualitative changes. In order to adapt to this change, operators need to build a large number of optical cable lines. Abundant pipeline resources are needed, but the pipeline resources of major operators are limited, and affected by municipal planning and engineering investment, it is difficult to rebuild pipelines when pipeline resources are insufficient, which requires greatly increasing the pipeline hole capacity. utilization rate. In recent years, the construction of fiber-to-the-home and FTTX in my country has gradually accelerated. Due to the limitation of...
