Embodiment 1

[0033] In this embodiment, the process flow of the continuous manufacturing method of plastic photonic crystal fiber is:

[0034] 1. The plastic monomer is MMA, using MMA raw materials with a purity of 99.9%;

[0035] 2. The purification device is a vacuum distillation system for the purification of MMA monomer;

[0036] 3. In the mixing and prepolymerization tank, in addition to the purified MMA monomer, add pure azobisisobutyronitrile or benzoyl peroxide initiator which accounts for 0.04% by weight of MMA, and add pure 0.2% by weight for MMA. N-butyl mercaptan chain transfer agent, fully mixed and pre-polymerized; the pre-polymerization reaction is to press 15kg / cm with nitrogen at a temperature of 90℃ 2 The prepolymerization tank is equipped with a stirrer and a heat exchange system to make the temperature of the mixture and the prepolymerization material in the tank uniform, which not only maintains the required prepolymerization temperature but also takes away excess heat.

Abstract

The invention relates to an optical fiber manufacturing technology, in particular to a manufacturing method of a plastic photonic crystal optical fiber. This manufacturing process is a continuous one-step method. Starting from the monomer raw material, the monomer is purified first, and then reacted and polymerized. The polymerized material is extruded through a die or melt-spun to become a preform of photonic crystal optical fiber. After hot drawing, it becomes a plastic photonic crystal fiber with a certain diameter. The continuous manufacturing method of the plastic photonic crystal optical fiber provided by the invention not only can be produced continuously in large quantities, but also saves time and effort, and significantly reduces the production cost.
