Abstract

The invention discloses a novel optical cable outer sheath material and a preparation method thereof. The optical cable outer sheath material is prepared from the following raw materials in parts by weight: 30 to 40 parts of polypropylene, 15 to 25 parts of modified lignin, 10 to 20 parts of modified cellulose, 10 to 20 parts of ABS plastic, 2 to 4 parts of interface compatibilizers, 1 to 2 parts of heat stabilizers, 2 to 3 parts of anti-ultraviolet agents, 1 to 2 parts of lubricant, 2 to 3 parts of antioxidant and 2 to 3 parts of fillers. According to the optical cable outer sheath material provided by the invention, the polypropylene is used as a main raw material, compared with an existing polypropylene sheath, the novel optical cable outer sheath material has the advantages of ultrahigh elasticity modulus, low-temperature brittleness resistance, high tensile strength, good glossiness, smooth effect and ageing resistance and mildew resistance, the defect of high water absorption of general polar materials after mixing is overcome, and compared with the prior art, obvious substantial characteristics and remarkable progress are achieved.

Description

technical field [0001] The invention belongs to the field of optical cable materials, and relates to a novel optical cable outer sheath material and a preparation method thereof. Background technique [0002] With the development of communication technology and the acceleration of the networking process, single-mode fiber optic cables with good signal transmission performance have been widely used. The optical cable must have an outer sheath so that it can maintain stable signal transmission under external influences such as impact stretching and bending. The tensile properties of the commonly used polyethylene outer sheath are generally not high and the elastic modulus is low, but if you meet the technical specifications with high elastic modulus and tensile properties, you can only rely on the method of increasing the thickness to meet the requirements. This increases the cost and unit weight, affecting procurement and construction. Contents of the invention [0003] A...
