High-hardness silicone-cored pipe with effect of protecting optical fibers

Abstract

The invention discloses a high-hardness silicone-cored pipe with an effect of protecting optical fibers. The silicone-cored pipe is prepared from the following raw materials in parts by weight: 190-200 parts of n-decyl hydrocarbon, 65-75 parts of linear C11 olefin, 190-200 parts of hydrogen-containing silicone oil, 15-20 parts of hydroxystearic acid, 4-6 parts of lithium hydroxide, 45-55 parts of a PE carrier resin, 5-7 parts of color master batch, 60-70 parts of high density polyethylene, 3.4-5 parts of sepiolite fiber, 5-7 parts of silica sol, 0.3-0.4 part of an antioxidant, 0.3-0.4 part of benzotriazole, 0.3-0.5 part of a silane coupling agent a171 and a proper amount of deionized water. The silicone-cored pipe prepared by the invention is low in preparation cost, excellent in wear resistance, high in environmental load resistance, wide in application prospect and worthy of popularization, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of silicon core tubes, in particular to a silicon core tube with a protective effect on optical fibers and high hardness. Background technique [0002] The 21st century is the era of information, the fastest growing is the information industry, the optical cable is the most important channel in the transmission of information, because only the optical cable can transmit a large amount of information at the fastest speed, and it will not be disturbed or lost. The rapid development of China's telecommunications industry in recent years has crossed the historical development stage from cable communication to optical cable, from civilian to military, from telephone to multimedia, and has entered the era of optical fiber communication, which has also greatly promoted the plastic optical cable sheathed pipe. development of. The optical cable is usually buried underground. In order to effectively protect the optic...

Problems solved by technology

[0003] Among silicone oil greases, methyl silicone oil grease is the most researched one. Since dimethyl silicone oil has poor thickening performance and poor compatibility with organic materials, methyl silicone oil grease has poor lubricating properties, etc. problem, which limits its scope of application

In the article "Preparation and Performance Research of Hydrocarbyl-Modified Silicone Oil Grease", Zhu Guojian used hydrogen-containing silicone oil and linear α-olefins for hydrosilylation reaction to obtain hydrocarbon-based modified silicone oil, and then made it with 12 hydroxystearic acid. Hydrocarbon-modified silicone grease was prepared by saponification reaction. The results showed that under similar viscosity, the oil film strength of hydrocarbon-modified silicone oil was greater than that of methyl silicone oil, and the lubricity was better. The refractive index of hydrocarbon-modified silicone oil was higher than that of methyl silicone oil. , closer to mineral oil, fat and organic matter, better compatibility with them, higher transparency, but the sintering load is close to that of methyl silicone oil, without improvement, and the properties of weather resistance, oxidation resistance and solvent resistance are average, The use field is reduced. In order to make the silicone oil grease can be well utilized in the silicon core tube, the present invention expands and modifies it on the basis of it, so that the prepared silicon core tube can meet the requirements of today's optical fiber for the silicon core tube. , actively reduce costs, save resources and protect the environment
