Abstract

The invention discloses an optical fiber outer sheath material and a preparation method thereof. The optical fiber outer sheath material is prepared from the following raw materials in parts by weight: 40-55 parts of polytrimethylene terephthalate, 5-10 parts of modified lignin, 25-35 parts of polybutylene terephthalate, 2-3 parts of ultraviolet-resistant material, 2-3 parts of compatilizer, 1-2 parts of antioxidant, 3-5 parts of coupling agent, 2-3 parts of nano composite hydroxide-inorganic filler powder and 0.1-0.2 part of dispersing agent. The optical fiber outer sheath material has the advantages of higher impact resistance, high tensile strength, high elastic modulus and favorable flame retardancy.

Description

technical field [0001] The invention relates to an optical fiber outer sheath material and a preparation method thereof. Background technique [0002] With the rapid development of informatization, the process of networking is accelerating, and the development of informatization has made single-mode optical fibers with good transmission performance widely used. As the number of optical fibers in the optical cable continues to increase with the increase in the amount of information, in order to keep the signal propagating in the optical fiber unaffected and save space, a parallel optical fiber was invented. After the fiber optic cable is twisted, it must have an outer sheath so that it can maintain stable signal transmission under external influences such as impact stretching and twisting. The impact resistance of the commonly used polybutylene terephthalate outer sheath is generally not high and the elastic modulus is low, and if you encounter technical specifications that ...
