Abstract

The invention relates to the technical field of optical fiber manufacturing, and in order to solve the problem that the existing coating resin for optical fiber is easy to accumulate oil in the quartz lamp tube during the LED light curing process, which leads to the brittleness of the optical fiber and the phenomenon of fiber breakage, a coating for optical fiber is provided. Resin and preparation method and application thereof, a coating resin for optical fibers, comprising a first coating resin and a second coating resin, the first coating resin is composed of acrylic-2-phenoxyethyl ester, vinyl hexa Hydrogen-2H-Nitrogen-2-Copper, First Photoinitiator, 3-Trimethoxysilylpropane-1-thiol, Trimethylolpropane Triacrylate, Tripropylene Glycol Diacrylate, 2-Ethylene Base-2-[(3-carboxy-1-oxopropoxy)methyl]propane-1, 3-diylbis[3-mercaptopropionic acid], graphene, the balance of the first auxiliary agent. The resin system of the invention can realize the rapid curing of LEDs, the coating curing rate is high, the volatile substances not excluded in the photocatalytic degradation system are degraded, and the quartz lamp tube has no oil accumulation.

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...
