Abstract

The invention discloses an ultraviolet curing coating for optical fiber coatings. The ultraviolet curing coating is prepared from 20-30 parts by weight of ethoxylated trimethylolpropane triacrylate, 30-41 parts by weight of cyclotrimethylolpropane methylal acrylate, 10-15 parts by weight of 2-(2-ethoxyethoxy)ethyl acrylate, 2-4 parts by weight of a photoinitiator 2959, 4-7 parts by weight of dipentaerythritol pentaacrylate, 3-6 parts by weight of tripropylene glycol diacrylate, 1-2 parts by weight of 3-glycidyloxypropyltrimethoxysilane, 1-2 parts by weight of glycidyl neodecanoate, 12-15 partsby weight of nano-attapulgite, 1-2 parts by weight of methyl-(butylcarbamoyl)-2-benzimidazole carbamate and 9-13 parts by weight of an aid. The ultraviolet curing coating has moderate viscosity, hardness and toughness, has good adhesion and has excellent chemical medium resistance.

Description

technical field [0001] The invention relates to an optical fiber coating material, in particular to an ultraviolet curing coating for 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, composite fiber, and fluorin...
