Abstract

The invention relates to an invisible optical cable and a self-adhering coating glue. The invisible optical cable sequentially comprises a natural-color optical fiber, a transparent tight sheath layer and a self-adhering coating layer from interior to exterior, wherein the self-adhering coating layer adopts a self-adhering coating glue; the self-adhering coating glue comprises the following components in percentage by weight: 40% to 45% of ethylene-ethyl acrylate copolymer, 11% to 15% of tackifier, 25% to 30% of synthetic wax or petroleum derivative wax, and the balance of other additives. The invisible optical cable has the advantages that by setting the prescription ratio of ethylene-ethyl acrylate copolymer, tackifier, and synthetic wax or petroleum derivative wax, the transparency of the self-adhering coating layer after curing is higher, the open time is longer, the uncuring strength or initial viscosity is higher, the construction is more convenient, and the construction property of the invisible optical fiber is improved.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to an invisible optical cable and a self-adhesive coating glue. Background technique [0002] At present, various manufacturers have developed optical cables that can be laid invisible, which are completely transparent, and the total outer diameter is only Ф0.9mm or less (Ф0.5mm), and the product performance fully meets the requirements of home access. This kind of optical cable does not need to be laid through pipes. It is not only beautiful, but also can be quickly and easily installed around skirtings, doors and windows, and decorative strips, minimizing disturbance to residents. [0003] At present, invisible home entry basically adopts two methods: self-adhesive layer and external adhesive layer: [0004] For the method of adding an adhesive layer: the invisible optical cable does not add self-adhesive coating glue, and a special hot-melt glue gun is used to heat the gl...
