Problems solved by technology

However, there are very few low-refractive index optical fiber coating resins available in the market, and the price is quite expensive. At the same time, due to military reasons, foreign countries restrict purchases from China, which seriously hinders the development of special optical fibers in China.

Abstract

The invention relates to low-refractive optical fiber coating resin. The low-refractive optical fiber coating resin is prepared from, by weight, 30-65% of prepolymer A, 0-40% of prepolymer B, 2-8% of a photoinitiator, 20-40% of an active diluent and 0.5-2% of a silane coupling agent, and the sum of the weight percentages of all the components is 100%. The low-refractive optical fiber coating resin is high in adhesive power, optical fiber is not likely to be broken when bent, and the low-refractive optical fiber coating resin is low in refractive rate and can enlarge the digital transmission aperture of the optical fiber.

Description

technical field [0001] The invention belongs to the field of optical fiber and optical fiber coating, in particular to a low refractive index optical fiber coating resin. Background technique [0002] With the development of the characteristic optical fiber industry, there are more and more requirements for optical fiber coating resin, and the optical fiber coating resin has become one of the bottlenecks in the progress of characteristic optical fiber. Generally, the refractive index of the inner coating resin of ordinary optical fibers is 1.48-1.50. However, special optical fibers used in some military and medical fields (such as active optical fibers, large core diameter optical optical fiber, etc.) must use a low-refractive-index optical fiber coating resin with a lower refractive index. At present, some high-performance energy-transmitting optical fibers require that the refractive index of the optical fiber coating resin be less than 1.355. However, there are very few...
