Abstract

The invention discloses hydrogen absorption type fiber paste for optical power grounded waveguide processing, and relates to the technical field of optical cable processing. The paste is prepared from, by weight, 5-10 parts of PEG-sodium of polyaspartic acid, 1-5 parts of sulfated castor oil, 1-3 parts of hydrogen absorption agent, 0.5-2 parts of hydrogenated rosin pentaerythritol ester, 0.5-2 parts of trimethylolpropane triacrylate, 0.05-0.5 part of C5 hydrogenated petroleum resin, 0.05-0.5 part of magnesium dimethacrylate and 50-70 parts of epoxidized soybean oil. According to the paste, thehydrogen absorption agent is added, so that the prepared fiber paste has good hydrogen absorption performance, incompatibility of fiber paste and stainless steel and hydrogen generated in the weldingprocess are effectively eliminated, defects in optical fiber crystal lattices are reduced, and optical fiber consumption is reduced, therefore the transmission performance of optical fibers is improved.

Description

Technical field: [0001] The invention relates to the technical field of optical cable processing, in particular to a hydrogen-absorbing fiber paste for processing ground wire composite optical cables and a preparation method thereof. Background technique: [0002] Ground wire composite optical cable, referred to as OPGW, is a kind of optical cable structure that combines optical fiber and overhead ground wire. It is used on high-voltage transmission and distribution lines. This is because the cable combines the two functions of grounding and communication, and is erected on the top of the high-voltage pole. Its shape is similar to that of the ACSR cable, and it adopts a concentric twisted structure. [0003] The ointment filled in the stainless steel tube fiber loose tube in the ground wire composite optical cable has higher requirements than the fiber ointment in the conventional optical cable, especially it needs to have good hydrogen absorption performance to eliminate th...
