Problems solved by technology

At present, most of the optical fiber coatings and bonding adhesives used in China rely on imports. The DeSolite series of optical fiber bonding adhesives produced by DSM has been occupying a monopoly position in the domestic market. Increase the production cost of domestic optical fiber and cable factories and limit the development of domestic optical fiber and cable industry

Abstract

The invention relates to a radiation curing composition for light guide fiber. The radiation curing composition is characterized by comprising the following components in percentage by mass: 30 to 70 percent of epoxy polyurethane acrylate, 20 to 60 percent of active monomer, 0 to 15 percent of adhesion promoting resin, 1 to 10 percent of auxiliary agent, 0.1 to 2 percent of polymerization inhibitor and 1 to 10 percent of optical initiator. The radiation curing composition prepared by using the scheme of the invention can be used for coating fiber and sticking combined belts, and can be prepared into a fiber inner layer coating, a fiber outer layer coating or a fiber belt combining resin by adjusting the formula. The radiation curing composition is characterized in that: a prepolymer adopted by the radiation curing composition is the epoxy polyurethane acrylate with four functional degrees, so the curing speed of the radiation curing composition is farther higher than that of other similar coatings, and the radiation curing composition can well meet the requirement of increasingly improved fiber wire-drawing speed.

Description

technical field [0001] The invention relates to an optical fiber coating, in particular to a radiation curing coating and an adhesive, which is especially suitable for optical fiber surface coating and tape bonding between colored optical fibers. Background technique [0002] In 1968, the German Bayer company developed the first generation of UV-cured wood coatings. After the coating was irradiated by ultraviolet light, photochemical reactions occurred, and the coating quickly polymerized and cross-linked, making the liquid coating instantly become a solid coating. Vinyl polymers are often used as film-forming resins in photopolymerization systems. The double bonds contained in them are easily opened by free radicals excited by light, resulting in a rapid reaction similar to chain growth. Linear polymers are instantly cross-linked into grid. Ultraviolet (UV) curing coatings and adhesives have been developed rapidly as a new curing technology. It has the advantages of energy...
