Fireproof flame-retardant plastic optical cable and preparation method thereof

Abstract

The invention discloses a fireproof flame-retardant plastic optical cable which is characterized by comprising a plastic optical fiber and a sheath wrapping the outer side of the plastic optical fiber. The plastic optical fiber comprises a plastic optical fiber core wire and a covering layer formed on the plastic optical fiber core wire; the plastic optical fiber core wire is prepared from the following components in parts by weight: 100 parts of an allyl methyl carbonate/GAM MA-butyrolactone-3-yl methacrylate/2-methyl-4-pentanoic acid copolymer, 4-8 parts of a nano hybrid hyperbranched polymer HB-SiO2, and 1-2 parts of boric acid; the covering layer is prepared from the following raw materials through ultraviolet curing: 5 to 8 parts of 2-[3-(2H-benzotriazole-2-yl)-4-hydroxyphenyl] ethyl 2-methacrylate, 15 to 25 parts of 2, 2, 3, 3-tetrafluoropropyl methacrylate, 8 to 12 parts of vinyl hyperbranched polysiloxane, 1 to 3 parts of glass fiber, 0.5 to 1.5 parts of a coupling agent and 0.4 to 0.8 part of a photoinitiator. The fireproof flame-retardant plastic optical cable disclosed by the invention is remarkable in fireproof flame-retardant effect, excellent in heat resistance, good in chemical corrosion resistance, aging resistance and durability and small in transmission loss.

Description

technical field [0001] The invention relates to the technical field of optical cable materials, in particular to a fire-resistant and flame-retardant plastic optical cable and a preparation method thereof. Background technique [0002] In recent years, with the advancement of science and technology and the development of society, communication technologies represented by mobile Internet, cloud computing, big data, and Internet of Things applications have risen rapidly, making optical cables widely used. Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. It is an indispensable engineering material for modernization and informationization. [0003] Currently common optical cables include plastic optical cables and inorganic glass-based optical cables. Inorganic gla...

Problems solved by technology

However, the fiber core of the fire-resistant and flame-retardant plastic optical cable is still made of polymethyl methacrylate, which still has the disadvantages of poor heat resistance, narrow temperature range, and further improvement in durability.
