Abstract

The invention relates to the technical field of manufacturing of optical fibers and provides coating resin for the optical fibers, a preparation method for the coating resin and an application of thecoating resin. The coating resin is used for solving the problem of the existing coating resins for the optical fibers that the optical fibers are embrittled and present a fiber cut phenomenon due tothe fact that quartz lamp tubes are prone to oil deposition during light-curing of LEDs. The coating resin for the optical fibers comprises first coating resin and second coating resin, wherein the first coating resin is prepared from ethyl-2-phenoxy acrylate, vinyl hexahydro-2H-azepin-2-one, a first photoinitiator, 3-trimethoxysilyl propane-1-thiol, trimethylolpropane triacrylate, tripropylene glycol bisacrylate, 2-ethyl-2-[(3-carboxyl-1-oxopropoxy)methyl]propane-1,3-diyl bis[mercaptopropionic acid], graphene and the balance of first auxiliaries. The resin system disclosed by the invention can achieve fast curing of the LEDs, the curing rate of a coating is high, un-removed volatile matters in the system are subjected to photocatalytic degradation, and quartz lamp tubes are free of oil deposition.

Description

technical field [0001] The invention relates to the technical field of optical fiber manufacturing, in particular to a coating resin for optical fiber and a preparation method thereof. Background technique [0002] In the existing wire drawing coating curing process, LED curing optical fiber is used to coat resin, realizing low energy consumption LED lamps instead of UV curing, but the temperature of LED lamp curing system is low, some volatile substances are not easy to discharge, and quartz lamp tubes are easy to accumulate oil , affecting the curing effect of the optical fiber, and in severe cases, the optical fiber becomes brittle and fiber breakage occurs. [0003] In order to avoid oil accumulation, the conventional method is to install an exhaust mechanism in the curing device, and inject an inert gas (such as nitrogen) to take away volatile substances during the curing process, but this method may cause the optical fiber to shake, and may also damage the curing envir...
