Abstract

The invention discloses a nylon cable sheath material for a polyester chain extender and a preparation method thereof. The nylon cable sheath material is characterized in that the raw material formula mainly comprises long-chain nylon, polyester and a compatilizer. The preparation method comprises the following steps: feeding the materials in the material formula to a closed mixer to mix for 3-15 minutes after preparing; pelletizing at 200-270 DEG C by using a twin-screw extruder, so as to prepare the nylon cable sheath material for the polyester chain extender. The nylon cable sheath material disclosed by the invention is applied to extruding and molding. The nylon cable sheath material has the advantages of being high in molecular weight, excellent in processability, heat resistant, low-temperature resistant, wearable, and good in chemical resistance, can be applied to a cable sheath, and still has excellent cracking resistance in a harsh low-temperature environment.

Description

technical field [0001] The invention relates to a nylon optical cable sheath material with polyester chain extension and a preparation method thereof, belonging to the technical field of communication optical cable materials. Background technique [0002] Nylon (another name for polyamide fiber, the English name Polyamide, abbreviated as PA) has excellent mechanical properties, self-lubricating properties, wear resistance, excellent oil resistance, chemical resistance and other good comprehensive properties. It is one of the five general-purpose engineering plastics. The variety with the largest output, the most varieties, and the widest range of uses. However, the current nylon products are mostly used for injection molding. Due to its low melt strength, it is difficult to be used for extrusion except for spinning. Due to the low molecular weight, low melt strength and poor low-temperature resistance of ordinary nylon materials, the melt tends to sag when used in the produ...
