Abstract

The invention relates to an optical cable skeleton material required by skeleton-type optical cables in the modern communication industry. The optical cable skeleton material is prepared from resins such as ultra-high-molecular-weight polyethylene XM-220 and metallocene polyethylene3518CB, and additives such as a toughening agent, an antistatic agent and a lubricant through the steps of high-speed mixing, blending implemented by using a twin-screw extruder, extruding, cooling, pelletizing, drying, and the like. The optical cable skeleton material disclosed by the invention has properties such as high strength, electric resistance and light signal attenuation resistance, and is extremely low in molding shrinkage rate and high in size stability; materials used by the skeleton material are high in purity, and after the materials are modified, the mechanical properties and electric properties of the materials can meet the requirements of optical fiber transmission; and the optical cable skeleton material disclosed by the invention is an ideal skeleton material applicable to skeleton-type ribbon optical cables which are high in optical fiber density, large in information transmission amount and small in optical cable diameter.

Description

technical field [0001] The invention relates to a reinforced polyethylene modified material used in the modern communication industry, in particular to an optical cable skeleton material required for a skeleton optical cable. Background technique [0002] With the rapid development of the optical fiber communication industry and the sharp increase in the demand for information, the traditional small-core optical cable has been difficult to meet the needs of actual communication. Due to the limitation of underground pipeline resources, there is an urgent need for an optical cable with a small outer diameter and a large number of cores in the market. Skeleton optical fiber ribbon cable has attracted attention due to its high fiber density, convenient construction and installation, and many other advantages. At present, in Japan, where optical fiber communication is developed, skeletal optical cables are the mainstream products, and skeletal optical cables are also widely used...
