Embodiment 1

[0037] Raw materials: get hydroxyethyl acrylate, ζ-caprolactone and phthalic anhydride, poly(ζ-caprolactone) and epoxy resin (manufacturer Changchun Chemical (Jiangsu Co., Ltd.) company), the mass ratio of brand BE-188EL) is 6:1.

[0038] The preparation method is as follows:

[0039] (1) Make hydroxyethyl acrylate and ζ-caprolactone under the catalysis of stannous octoate and in an inert atmosphere, adjust the temperature to 80°C, react for 3 hours, then precipitate poly(ζ-caprolactone) with petroleum ether (PCL).

[0040] (2) Make poly(ζ-caprolactone) and phthalic anhydride react in toluene solvent under the catalysis of triethylamine, the temperature is maintained between 80-100 ℃, after reacting for 2 hours, to the reaction system Add standard bisphenol A epoxy resin to it, and react until the acid value is less than 2mg / KOH.

[0041] (3) After removing most of the solvent, precipitate the product with petroleum ether to obtain poly(ζ-caprolactone)-modified epoxy acryli...

Embodiment 2

[0043] Raw materials: hydroxyethyl acrylate, ζ-caprolactone and phthalic anhydride are used in a mass ratio of 1:10:1.27, and the mass ratio of poly(ζ-caprolactone) and epoxy resin is 11:1.

[0044] The preparation method is as follows:

[0045] (1) Make hydroxyethyl acrylate and ζ-caprolactone under the catalysis of stannous octoate and in an inert atmosphere, adjust the temperature to 85 ° C, react for 6 hours, then precipitate poly(ζ-caprolactone) with petroleum ether (PCL).

[0046] (2) Make poly(ζ-caprolactone) and phthalic anhydride react in toluene solvent under the catalysis of triethylamine, the temperature is maintained between 80-100 ℃, after two hours of reaction, to the reaction system Add standard bisphenol A epoxy resin to it, and react until the acid value is less than 2mg / KOH.

[0047] (3) After removing most of the solvent, precipitate the product with petroleum ether to obtain poly(ζ-caprolactone)-modified epoxy acrylic resin (PCLER).

Abstract

The invention provides a coating composite, which comprises poly(zeta-caprolactone) modified epoxy acrylate, activated monomer, a cross-linking agent, a photoinitiator, nanometer pigment and reasonable amount of auxiliary material. The invention also provides an optical fiber coated with the coating composite. The optical fiber colored by using the coating composite has pure and bright color and soft texture, is anti-bacteria and has small additional attenuation; and simultaneously, the coating composite can improve the coloring speed of the optical fiber.

Description

technical field [0001] The invention relates to a coating composition and an optical fiber comprising the same. Background technique [0002] Optical glass fiber has been widely used in the field of telecommunication, but because the fiber itself is easily deformed or even broken by the environment including dust, moisture and mold, which affects the transmission of signals. In order to protect the optical fiber, improve the quality of optical fiber signal transmission, and prolong the service life of the optical fiber, people coat one or more layers of paint on the outside of the optical fiber. Usually there are two layers of optical fiber coating: the first layer is a soft inner layer, which mainly protects the optical fiber and reduces the signal loss caused by microbending; the second layer is a tough outer layer, which mainly serves to increase the mechanical strength of the optical fiber and Protect the role of optical fiber. In addition, there is usually a colored c...
