Problems solved by technology

The light-curing packaging adhesives commonly used in the market are not specially designed for pigtail packaging. Although the curing speed is fast, the pigtails are not easy to peel off from the curing adhesive after fixing, which affects the assembly efficiency of the gyroscope and may even cause fiber breakage. Fiber optic rings and fiber optic gyroscopes scrapped

Abstract

The invention relates to a radiation-curable fiber-optic ring tail fiber packaging adhesive. The adhesive comprises the following components in percentage by weight: 35.5-70% of radiation curable oligomer, 15.5%-50% of an active diluent, 3-10% of a photoinitiator, 0.05-3% of a flatting agent, 0.01-0.5% of a defoaming agent and 0.05-1% of a polymerization inhibitor, wherein the sum of each component meets 100%. The radiation-curable fiber-optic ring tail fiber packaging adhesive is easy to rapidly fix and peel, prevents sliding and resists vibration and the production efficiency and success rate of fiber-optic ring and fiber-optic gyroscope can be significantly increased.

Description

technical field [0001] The invention belongs to the field of adhesives, and specifically refers to a radiation-curable packaging adhesive used for fixing optical fiber ring pigtails in the assembly process of optical fiber gyroscopes. Background technique [0002] As a fiber optic sensor for inertial navigation, fiber optic gyroscopes are used in aviation, navigation, aerospace and defense industries. The fiber optic ring is the core component of the fiber optic gyroscope’s optical path. Since the core diameter of the exposed fiber pigtail of the fiber optic ring is thin and fragile, the finished fiber optic ring needs to be packaged and fixed before the fiber optic gyroscope is assembled to avoid damage caused by collisions during the assembly process. In the event of fiber breakage, the pigtail must be easily stripped from the encapsulant during assembly without damaging the pigtail. The packaging glue for fiber optic ring pigtails is generally wet glue or solvent-based g...
