High-viscosity reinforced silicon core pipe with flame retardant function

Abstract

The invention relates to a high-viscosity reinforced silicon core pipe with a flame retardant function. The high-viscosity reinforced silicon core pipe sequentially comprises a high-density polyethylene layer and a solid lubricating layer sequentially from outside to inside, and is characterized in that a bonding layer is arranged between the high-density polyethylene layer and the solid lubricating layer, and short glass fibers are added in the solid lubricating layer; a flame retardant layer is arranged on the outer side of the high-density polyethylene layer. The high-viscosity reinforced silicon core pipe has the advantages that the bonding layer is added into the high-density polyethylene layer and the solid lubricating layer, so that cohesiveness between the high-density polyethylene layer and the solid lubricating layer is improved; the short glass fibers are added into the solid lubricating layer, so that strength of the silicon core pipe is improved; the flame retardant layer is added to the high-density polyethylene layer, and accordingly certain flame-retardant effect can be achieved.

Description

technical field [0001] The invention relates to the field of pipes, in particular to a high-viscosity reinforced silicon core pipe with flame-retardant function. Background technique [0002] Silicon core tube is a new type of composite tube with silica gel solid lubricant on the inner wall. It has good sealing performance, chemical corrosion resistance and low engineering cost. It is widely used in optical cable communication network systems such as highways and railways. HDPE silicon core pipe is a new type of composite pipe with silica gel solid lubricant on the inner wall, referred to as silicon pipe. Widely used in optical cable communication network systems. However, in the existing silicon core tube, the high-density polyethylene layer and the core layer are easily separated during use, and the silicon core tube of this structure has low strength and is easy to burn at high temperature. Contents of the invention [0003] In view of the above disadvantages, the pur...
