Problems solved by technology

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

Abstract

The invention relates to optical fiber coloring ink with capacity of radiation curing. The optical fiber coloring ink is characterized by comprising components in percentage by weight as follows: 1%-20% of color paste, 20%-40% of an activated diluent, 0.5%-4% of an auxiliary A, 40%-60% of UV resin and 3%-10% of a photoinitiator and an auxiliary initiator, and the percentage sum of the component is 100%. The optical fiber coloring ink with the capacity of radiation curing is high in curing speed and good in curing effect, an optical fiber colored by the ink has bright color and luster and smooth surface, is fadeless, touches good, and can be effectively distinguished in darker light.

Description

technical field [0001] The patent of the present invention relates to the field of optical fiber and optical fiber coating, and the ink is suitable for coating the colored layer of optical fiber. 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 high-spee...
