Description
Technical field
The present invention relates to a kind of optical fiber adhesive glue, be specifically related to the adulterated epoxy resin optical fiber of a kind of nanometer uv-absorbing agent adhesive glue, its cohesive force is strong, the anti-ultraviolet ageing performance is good, bonding quality is high, can be used for fixing between optical fiber cable and the junctor.
Background technology
Opticfiber communication is one of important way of present information transmission, and it has, and capacity is big, repeater span length, good confidentiality, do not receive advantages such as EMI and saving copper material.The optical fiber tackiness agent is to be used for a kind of tackiness agent of being adhesively fixed between optical fiber cable and the junctor; Because its special use range; Therefore it is had relatively high expectations, below needing to satisfy some: cohesive force that ⑴ is stronger and persistence, can be after bonding because of the ectocine mobile phenomenon that occurs coming unstuck; ⑵ high light transmittance can not produce light conduction refraction action after the use, can not cause transmission loss; ⑶ stability is high, and high temperature resistant high erosion and low temperature resistant has good resistivity.
Common having in practical application: AB glue, thermocoagulation epoxy resin glue, ultraviolet solidification adhesive, inject thermosol and anaerobic glue etc. in advance.In recent years; Anaerobic glue obtains using more widely because of its setting rate needs curing oven soon and not; But it in use, and must use ionic catalyst to handle can solidify, if tackiness agent does not touch ionic catalyst; Then will can not solidify, and cause optical fiber to be fixed and produce piston effect.AB glue is made up of host and solidifying agent two portions, and its host adopts epoxy resin more, have with low cost, the transparency is good, advantages such as the good and complete processing maturation of mechanics and thermal property.Aromatic epoxy resin contains can absorb ultraviolet phenyl ring; Meeting oxidation flavescence after the absorption ultraviolet ray, and cycloaliphatic epoxy resin can form stiff molecule structure closely because epoxy group(ing) directly is connected on the alicyclic ring; Solidifying the back cross-linking density increases; Make the material after solidifying have higher heat-drawn wire, because of not containing phenyl ring, show good anti-UV performance and agent of low hygroscopicity in the molecular structure.
The adulterated cycloaliphatic epoxy resin optical fiber of the nanometer uv-absorbing agent adhesive glue of two-pack among the present invention; Cycloaliphatic epoxy resin is earlier through organic-silicon-modified in the one side A component; In structure, introduce the Si-O key, have more advantages such as transmittance height, heat-resistant stability is good, ultraviolet resistance is strong, water absorbability is low after the curing; Improve the anti-ultraviolet ageing performance of this optical fiber adhesive glue through adding the uv-absorbing agent nano titanium oxide in the B component on the other hand; And the photopolymerization that cation curing agent causes has advantages such as not receiving oxygen inhibition, volumetric shrinkage are little, thick film; It is bonding reliably both to have guaranteed that optical fiber cable and junctor formed; Can play again and fill up the device space and prevent effects such as high loading pressurized, make it be more suitable for being used for being adhesively fixed of optical fiber cable as high-quality adhesive glue.
Summary of the invention
