Abstract

The invention discloses a preparation method of a flame retardant optical cable filler. By attaching ash after straw combustion on the surface of the asphalt strip, the asphalt strip is used as a filler to produce an optical cable protective layer containing the asphalt strip. When the optical cable catches fire, the asphalt strip plays a physical blocking role to prevent the fire from spreading,thus solving the problems that the existing flame retardant filler has limited flame retardant effect, cannot achieve ideal flame retardant effect, and needs to be improved.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to a preparation method of a flame-retardant optical cable filler. Background technique [0002] 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. [0003] Flame retardant fillers need to be added in the production process of existing optical cables to increase the flame retardant properties of optical cables. However, the existing flame retardant fillers have limited flame retardant effects and cannot achieve the ideal flame retardant effect, and need to be improved. Contents of the invention [0004] The object of the present invention is to provide a preparation method of flame-retardant optical cable filling material to solve the above technical problems. [0005] In...
