Description
Technical field
The invention belongs to low-smoke halogen-free flame-retardant sheath material preparation technical fields, and in particular to one kind is suitable for air-blowing and is laid with light
Cable low friction low-smoke halogen-free flame-retardant sheath material and preparation method thereof.
Background technique
Common low smoke halogen-free fire retardant polyolefin cable material is mostly with LLDPE(linear low density polyethylene), EVA(ethylene-second
Vinyl acetate copolymer) it is main resin base material, it is aided with a small amount of interfacial compatibilizer and is filled with a large amount of inorganic fire retardants and (changes
Learn the ultrafine aluminium hydroxide or magnesium hydroxide of synthesis).Although being aided with silicone or PE wax or EVA wax or amide waxe in CABLE MATERIALS, so
And the CABLE MATERIALS of this type is because inorganic fire retardants is mostly the hard of tapering thorn-like or irregular shape in microstate
Crystalline object adds too many lubricant and will lead to and skids in screw extruder, and protecting sleeve of optical cable difficulty is caused to be processed in optical cable factory, profit
Lubrication prescription add it is few, coefficient of friction drop do not get off, so coefficient of friction is generally not less than 0.25.Therefore optical cable is blown in progress air-flow
When laying, enough quantity optical cables cannot be laid in limited caliber because mutual frictional resistance is excessive.It is especially anfractuose
It is more difficult to be laid in pipeline.It is brought if coefficient of friction can easily be blown in closed more dog leg pipings with air-flow lower than 0.15
Laying optical cable.
