Flame-retardant silicon core bundled tube for communication

Abstract

The present application relates to the technical field of silicon core pipe, and proposes a kind of communication with flame-retardant silicon core cluster pipe, it is double-layer pipe structure, including outer layer and inner layer, characterized in that, the outer layer includes the following weight parts of raw materials: high-density polyethylene 85~105 parts, ethylene-vinyl acetate copolymer 5~10 parts, flame retardant 8~12 parts, compatible agent 8~13 parts, lubricant 5~10 parts, plasticizer 5~10 parts, carbon black 2~3 parts, antioxidant 1~2 parts;The inner layer includes the following weight parts of raw materials: silicon core masterbatch 3~5 parts, high-density polyethylene 60~70 parts, flame retardant 0.5~1 part.By the above technical solution, the poor flame retardancy of the silicon core pipe in the prior art, the poor mechanical properties of the silicon core pipe in the prior art are solved.
