Abstract

The invention discloses a preparing method of a flame retardant optical cable filler and relates to the technical field of communication materials. The filler includes guanidine sulfamate, mineral oil, N,N'-dicyclohexylcarbodiimide, phosphonitrilic chloride trimer, sodium hydroxide, thiourea, nylon, silica, epoxidized soybean oil, an impact modifier ACM, polyethylene wax, an anti-aging agent, N-cyclohexyl-2-benzothiazolesulfenamide, vaseline, precipitated calcium carbonate, polybutylene, zinc carbonate, stearic acid, modified silica-thickened poly(alpha-olefin) and dibutyl ester. A preparing process of the filler is environmentally friendly, equipment used is simple, operation is simple, the preparing cost is low, and the prepared filler has high rheological and bending properties, high compressive strength and high mechanical protection performance, can avoid damage by outside environment and can effectively prolong the service lifetime of optical cables.

Description

Technical field: [0001] The invention relates to the related technical field of communication materials, in particular to a preparation method of a flame-retardant optical cable filler. Background technique: [0002] The optical cable is manufactured to meet the 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. Optical cables are mainly composed of optical fibers (thin glass filaments such as hair), plastic protective sleeves and plastic sheaths. There are no metals such as gold, silver, copper and aluminum in the optical cables, and generally have no recycling value. An optical cable is a communication line in which a certain number of optical fibers compose a cable core in a certain way, and are covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. ...
