Problems solved by technology

In addition to being able to cope with the external environment of hot and humid changes, the adhesive used in the processing and production of optical fibers needs to have good weather resistance and strong shear strength. The optical fiber adhesives in the prior art are often very weak. It is difficult to achieve a balance between the two, either has strong shear resistance but poor weather resistance, or has good weather resistance but poor shear resistance

Abstract

The invention discloses glue for optical fibers and a preparation method of the glue.The glue is prepared from, by weight, a component A and a component B.The component A comprises 100 parts of epoxy resin, 10-15 parts of silane coupling agent and 5-10 parts of flexibilizer.The component B comprises 10-35 parts of curing agent and 0.5-5 parts of thixotropic agent.The flexibilizer is carboxyl-terminated butadiene acrylonitrile rubber and / or monoisocyanate-terminated polyurethane.The epoxy resin is poly-glycidyl ether epoxy resin.The weight ratio of the component A to the component B is (10-30):(1-5).The glue for the optical fibers is good in weather fastness and has high shear force resisting strength and peel resisting strength, and the preparation method of the glue for the optical fibers is simple and convenient.

Description

technical field [0001] The invention relates to a glue for optical fiber and a compounding method thereof. Background technique [0002] Bonding technology is widely used in transportation, equipment manufacturing, automobile manufacturing and other fields. With the popularization of the Internet, the application of adhesives in the assembly of optical materials and optical components is becoming more and more extensive. In addition to being able to cope with the external environment of hot and humid changes, the adhesive used in the processing and production of optical fibers needs to have good weather resistance and strong shear strength. The optical fiber adhesives in the prior art are often very weak. It is difficult to achieve a balance between the two. Either it has strong shear resistance but poor weather resistance, or it has good weather resistance but poor shear resistance. Contents of the invention [0003] The technical problem to be solved by the present in...
