High density polyethylene self-lubricating optical fibre cable sheath tube

Abstract

A sheathing tube of self-lubricating optical fiber cable is processed after the composite of high-density polythene as the main outer layer material and the sold self-lubricating composite material as the main inner layer material processed by compounded coextrusion, among which the proportion mix of the outer layer material is high-density polythene: 90% and composite reinforcer 10% and that of the inner layer material is silicone resin: 80%, surfactant 10%, silicon oil: 10%.

Description

technical field [0001] The invention relates to a polyethylene optical fiber cable sheathing tube, in particular to a high-density polyethylene self-lubricating optical fiber cable sheathing tube whose inner layer is a solid self-lubricating composite material. Background technique [0002] The use of sheath tubes for optical fiber cables has become a development trend in the application of the communication field, and the requirements are getting higher and higher. At present, the inner layer of the sheath tube used by people is made of silicone material, and the self-lubricating function of the inner wall of the core layer is weak, which is not conducive to the application of optical fiber cables that require fast cable blowing speed. Contents of the invention [0003] The task of the present invention is to provide a high-density polyethylene self-lubricating optical fiber cable sheathing tube with good self-lubricating function on the inner wall of the core layer, fast...
