Problems solved by technology

At present, major optical cable factories require that the colored optical fiber be soaked in fiber paste at 85°C for one month without the coloring layer falling off. This has strict requirements on the aging resistance of the coloring layer. Ordinary UV inks cannot meet the requirements of optical fiber coloring inks at all. Require

Embodiment 1

[0047] This embodiment provides a UV fast-curing optical fiber white ink. The composition and preparation method of the ink are as follows:

[0048]

[0049] The above raw materials were fully stirred at 60°C for 2.5 hours, and after the photoinitiator was completely dissolved, they were filtered to obtain a UV fast-curing optical fiber white ink.

[0050] The viscosity of the optical fiber white ink prepared in this example is 3500cps (25°C), the average particle size is 0.65um, and it is placed at room temperature for seven days without sedimentation. After UV curing, the double bond conversion rate of the optical fiber white ink is 86%. Higher, butanone wipes 50 times without fading, strong tinting power, dynamic friction coefficient of 0.080, and high surface smoothness.

Abstract

The invention discloses UV fast curing optical fiber coloring ink which is prepared from the following components in percentage by weight: 25 to 35 percent of color paste, 20 to 40 percent of acrylateresin, 10 to 30 percent of an acrylate reactive diluent, 12 to 20 percent of a photoinitiator, 4 to 10 percent of a leveling agent and 1 to 10 percent of a defoamer. The UV fast curing optical fibercoloring ink prepared by the invention is high in coloring strength, uniform in particle size distribution, not easy to settle, high in surface smoothness and relatively good in stripping property, has the most important characteristics of extremely fast curing and extremely high double bond conversion rate, and can be suitable for relatively high coloring speed.

Description

technical field [0001] The invention relates to the technical field of optical fiber coloring ink; in particular, it relates to a UV fast-curing optical fiber coloring ink and a preparation method thereof. Background technique [0002] Optical fiber coloring ink is a kind of ultraviolet radiation photocurable ink specially used for optical fiber coloring. Its main function is to manufacture colored optical fibers so that optical fibers can still be effectively distinguished after being prepared into optical cables. High-performance optical fiber coloring ink has no effect on the performance of optical fiber, such as strength, reliability, stability, attenuation, and microbending. The ink coated on the outside of the optical fiber can also act as a barrier to the environment, especially to dust and water, thereby reducing the impact of environmental effects on the performance of the optical fiber. [0003] The traditional optical fiber coloring speed is 500-2400m / min, such a...
