Problems solved by technology

In recent years, anaerobic adhesives have been widely used because of their fast setting speed and no need for curing ovens. However, when they are used, they must be treated with ion catalysts to be able to solidify. If the adhesive does not come into contact with ion catalysts, it will Will not solidify, causing the fiber cannot be fixed and produce piston effect

Abstract

The invention relates to a two-component transparent epoxy resin optical fiber adhesive which is formed by a base resin A and a curing agent B. components A and B are mixed at a proportion of 1: (0.01-0.02) and then used for construction, wherein component A is composed of 94.5%-96% of cycloaliphatic epoxy resin, 3%-5% of a flexibilizer and 0.3%-1.0% of a defoaming agent, and component B is a cation type curing agent. The optical fiber adhesive is transparent, low in viscosity, high in adhesion, not easy to crack, temperature and corrosion resistant; can be widely applied to optical fiber cable connectors, optical components and optical communications; and is simple in preparing process, low in producing cost, and suitable for mass industrial production.

Description

technical field [0001] The invention relates to an optical fiber adhesive, in particular to an epoxy resin optical fiber adhesive, which has high bonding quality and can be used for fixing between optical fiber cables and connectors. Background technique [0002] Optical fiber communication is one of the important ways of modern information transmission. It has the advantages of large capacity, long relay distance, good confidentiality, no electromagnetic interference and copper saving. Optical fiber adhesive is a kind of adhesive used for bonding and fixing between optical fiber cables and connectors. Due to its special scope of use, it has high requirements for it, and the following points must be met: (1) Strong bonding Strength and durability, after bonding, there will be no degumming and movement due to external influences; (2) High light transmission, no light transmission and refraction after use, and no transmission loss; (3) High stability, high temperature and high...
