The invention discloses a fast-curing UV-heating dual-curing optical fiber epoxy adhesive and a preparation method thereof. The UV-heating dual-curing optical fiber epoxy adhesive is prepared from the following raw materials in parts by mass: 20-50 parts of epoxy acrylate, 20-50 parts of polyurethane acrylate, 10-30 parts of reactive diluent, 1-5 parts of photoinitiator, 1-5 parts of epoxy resin curing agent, 5-10 parts of filler and 1-5 parts of auxiliary agent; the epoxy acrylate includes bisphenol a type epoxy acrylate. The prepared UV-heating dual-curing optical fiber epoxy adhesive has the characteristics of low shrinkage rate, quick curing and good bonding force. |
