Embodiment Construction

[0036] The typical formula of the hydrogen-absorbing fiber paste of the present invention is as follows:

[0037]

[0038] 1. The base oil is poly-a-olefin synthetic oil, which has excellent high and low temperature characteristics and low volatility.

[0039] 2. The gelling agent adopts an organic-inorganic composite gelling agent; the organic gelling agent is EPDM rubber, styrene-ethylene propylene rubber block copolymer or a mixture thereof. The inorganic gelling agent is fumed white carbon black. The use of organic-inorganic composite gelling agent can make the structure of the paste more stable, and can achieve a balance between reducing oil separation and improving fluid acceptance.

[0040] 3. Antioxidant is AT-215. The main antioxidant tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester (referred to as 1010) and the auxiliary antioxidant tris(2,4 One di-tert-butylphenyl) ester (abbreviated as 168) compound antioxidant AT215 comp...

Abstract

The invention relates to a formula of hydrogen absorption type fiber paste, which comprises the following components in percentage by weight: 80-84% of base oil, 9-11% of gelling agent, 0.5-2% of antioxygen, 0.5-2% of viscosity index improver, 0.5-2% of oil-separation inhibitor and 4-6% of hydrogen absorbing agent, wherein the gelling agent is organic-inorganic composite gelling agent; the organic gelling agent accounts for 7-9wt%, and the inorganic gelling agent accounts for 1-3wt%; and the hydrogen absorbing agent is a carbon nanotube. Because the carbon nanotube is added into a fiber paste matrix to serve as the hydrogen absorbing agent in the formula, the hydrogen absorption type fiber paste has a good hydrogen absorption performance, and free nitrogen can be effectively adsorbed to prevent the free nitrogen from damaging an optical fiber.

Description

[0001] technical field [0002] The invention relates to a formula of hydrogen-absorbing fiber paste and a preparation method thereof. [0003] Background technique [0004] OPGW (Optical Ground Wire, optical fiber composite overhead ground wire) is a form of optical cable structure that combines optical fibers and overhead ground wires. It is used on high-voltage transmission and distribution lines. This kind of optical cable combines the two functions of grounding and communication. It is erected on the top of the high-voltage pole. Its shape is similar to that of ACSR cables, and it adopts a concentric twisted structure. From the late 1970s to the early 21st century, the structure of the OPGW optical cable has undergone great changes. Since the structure of the overhead ground wire is basically finalized, the change in its structure is mainly the improvement of the optical fiber unit. In the early days of the development of the OPGW optical cable, the optical fiber unit ...
