Description

technical field [0001] The invention relates to the technical field of optical fiber sheathing materials, in particular to a cable protection material and a preparation method thereof. Background technique [0002] With the rapid development of the data communication industry, optical fiber is being widely used as the carrier of data transmission. The laying forms of optical fiber are buried and overhead, and with the transformation of urban network lines, most of them have been transferred underground. In order to prevent underground optical fibers and optical cables from being bitten or corroded by insects, sheath materials for optical fibers and optical cables have emerged as the times require. At present, polyolefin is mainly used as the sheath material of optical fiber and optical cable, which has the characteristics of light weight, high bending strength, small friction coefficient, good sealing performance, and corrosion resistance. However, this kind of pipe has the...

Problems solved by technology

[0003] Inorganic halogen-free flame retardants have strong polarity and hydrophilicity, while polyolefins are non-polar materials, the compatibility between the two is poor, and it is difficult to form a good bond and bond at the interface, especially carbon fiber carbon fiber has Excellent flame retardancy, smoke suppression, drip resistance, acid resistance and other functions have been widely used. However, carbon fiber has strong polarity and is different from resin in thermal expansion coefficient. Thermal expansion and contraction during processing and molding will cause fine cracks at the interface between the two phases. This will lead to a decline in the mechanical properties, waterproof performance, and insulation properties of the material, so the surface of the carbon fiber must be modified so that the carbon fiber has better comprehensive properties in polyolefins, and has good fluidity and service temperature at the processing temperature. It has both high strength and toughness, and does not change the impact resistance of polyolefin profiles
