Abstract

The invention discloses an aging-resistant flame-retardant ultraviolet-curable optical fiber coating. The aging-resistant flame-retardant ultraviolet-curable optical fiber coating is prepared from 50-57 parts by weight of propoxyglycerol triacrylate, 10-14 parts by weight of 1, 1-dimethyl-2, 2, 3, 4, 4, 4-hexafluorobutyl methacrylate, 3-6 parts by weight of ethoxylated trimethylolpropane triacrylate, 3-5 parts by weight of a photoinitiator 1844, 7-10 parts by weight of ethoxylated bisphenol A diacrylate, 5-7 parts by weight of isobornyl methacrylate, 2-4 parts by weight of gamma-aminopropyltriethoxysilane, 1-2 parts by weight of 4-methoxyphenol, 4-6 parts by weight of nano-clay, 1-2 parts by weight of methyl-(butylaminoformyl)-2-benzimidazole carbamate, and 9-13 parts by weight of an aid.The aging-resistant flame-retardant ultraviolet-curable optical fiber coating has high anti-oxidation and anti-aging properties, good leveling properties, a fast curing rate and good adhesion.

Description

technical field [0001] The invention relates to an optical fiber coating material, in particular to an aging-resistant and flame-retardant ultraviolet light curing optical fiber coating and a preparation method thereof. Background technique [0002] Optical fiber, referred to as optical fiber (optical fiber), is a thin fiber-like material made of plastic or glass. When light passes through it, it can form total reflection and transmit. Compared with the loss of electricity in wire transmission, the loss of light in optical fiber transmission is much lower. Therefore, optical fiber has many advantages such as low loss, small size, wide frequency band, anti-interference, light weight, and high efficiency. It is widely used as a material for long-distance information transmission. The emergence of optical fiber has laid a solid foundation for the rapid development of modern communication technology. Common fiber types include silica fiber, fluorine-doped fiber, infrared fiber...
