Abstract

The invention discloses a fiber filling paste and a preparation method thereof. The fiber filling paste comprises the following formula ingredients with the following weight percentage: 75%-92% of oil base material, 0.05%-8% of hydrogen absorbing material, 3%-15% of thermoplastic elastomer, 0.1%- 5% of antioxidant, and 0.01%-3% of pour point depressant. The fiber filling paste has the hydrogen-absorption function through the use of the hydrogen absorbing material, and meanwhile adopts the thermoplastic elastomer as a constitution body of a paste net structure. The fiber filling paste has good compatibility with a plurality of oil base materials and adopts the antioxidant and the pour point depressant compositely to have a synergies effect, thereby preventing the risks of high viscosity of the filling paste, hard cone penetration, high hydrogen evolution value and oil paste leakage due to the use of silicon dioxide inorganic thickening agent, calcined silicon dioxide or bentonite. The preparation process is simple; the requirement on the manufacture device is low; and each performance index of products is convenient to control.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an optical fiber filling paste and a preparation method thereof. Background technique [0002] China's communication industry is developing rapidly, and the output of optical cables as communication infrastructure is also increasing year by year, and optical cables are playing an increasingly important role in the transmission network. In 2013, the domestic optical fiber production capacity will be 150 million core kilometers, which will continue to be in short supply, and the optical cable will drive the vigorous development of the entire industrial chain. On August 17, 2013, the State Council issued the "Notice on the "Broadband China" Strategy and Implementation Plan", requiring that by the end of 2013, wireless local area networks will basically achieve hotspot coverage in important public areas in cities; Household and rural broadband access to rural a...
