Problems solved by technology

The core materials of solid-state core-through-body light-emitting optical fibers mainly include quartz, glass and polymer materials, and their lengths can be cut arbitrarily. Effect)
The core material of the liquid core light-emitting optical fiber is silicone oil, semi-solidified silica gel, etc. (the skin material is transparent polyethylene, polyvinyl chloride tube), which has the advantage of good flexibility, but the manufacturing process is complicated, the yield is low, and the price is high. , can not be cut on site, can only pre-order the length according to the needs

Abstract

The invention relates to the field of high polymer materials, in particular to a preparation method for surface light-emitting plastic optical fiber. The surface light-emitting plastic optical fiber is prepared by the steps of preparation of auxiliaries and molding. The preparation method has the capabilities of effectively reducing the production cost of existing surface light-emitting plastic optical fiber and expanding the application field thereof. Manufacturing equipment and process used for preparing the surface light-emitting plastic optical fiber in the preparation method are relatively universal to those used for preparing end surface light-emitting plastic optical fiber, however, a second-phase additive which is uniformly distributed in a certain proportion exists in a core material, and the size of the second-phase additive is distributed within a certain range, such that a part of light beam which is injected from an optical fiber end surface and irradiates to the surface of the optical fiber is reflected to the outside of a skin material to generate a surface light-emitting effect.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a method for preparing a whole-body light-emitting plastic optical fiber. Background technique [0002] Plastic optical fiber is a new type of optical fiber with plastic as the light-guiding medium. According to the transmission mode of the light beam, it can be roughly divided into two categories: end-face light-emitting optical fiber and whole-body light-emitting optical fiber. The former is that the light beam is injected from one end face of the optical fiber, and the optical fiber is emitted from the other end face after multiple total reflections between the fiber core material and the skin material interface, which can be used for information transmission. It is expected that it exits the side of the fiber. [0003] Whole body light emitting fiber is also called side light emitting fiber, side light fiber. Different from the end-face optical fiber, the light beam basica...
