Abstract

The invention relates to a plastic optical fiber extrusion preparation method. The plastic optical fiber extrusion preparation method comprises the following steps that PbS nanoparticles are doped in a core polymer; a core material and a shell layer raw material are respectively heated to 60+ / -5 DEG C, and are mixed according to a ratio of 1: 3; the mixture is extruded through a mold nozzle to obtain mixture filaments; the closed dispersion is performed for the mixture filaments in constant-temperature environment of 80+ / -5 DEG C; then, the cooling is performed; and the treated mixture filaments are coated by a polyolefin material, are heated after coating, are stretched to reach a target diameter, and are cooled to obtain plastic optical fibers. The method is high in production efficiency; the produced plastic optical fibers overcome the defect of step optical fiber dispersion; and the PbS nanoparticles are doped in the core polymer, so that the refractive index is increased, and the optical fibers are better in performances.

Description

technical field [0001] The invention relates to the technical field of plastic optical fiber processing, in particular to a plastic optical fiber extrusion preparation method. Background technique [0002] At present, the optical fibers used in communication optical cables are basically made of silica optical fibers, made of high-purity silica SiO 2 With the addition of an appropriate amount of dopant, it shows certain advantages in long-distance information transmission due to its low loss and high resistance to electromagnetic interference, but it encounters problems that are difficult to connect due to thin fiber cores when entering the home. Difficult, while installation and maintenance costs are relatively high, not suitable for the needs of LAN. The plastic optical fiber has the characteristics of thick fiber core, easy installation and maintenance and low cost, and has begun to be applied. However, in the current plastic optical fiber production methods, it is diffi...
