Embodiment 1

[0019] A preparation method for optical fiber surface coating glue, it comprises the following steps:

[0020] S1. Kneading: In the rubber kneader, add high molecular weight polyisobutylene, silicone rubber, medium molecular weight polyisobutylene, low molecular weight polyisobutylene, antioxidant, glass fiber, and silicate for kneading. The kneading time is 30 to 50 minutes. The temperature is 120-160°C, calculated in parts by weight, silicone rubber: 25-30 parts; high-molecular-weight polyisobutene: 5-10 parts; medium-molecular-weight polyisobutene: 5-10 parts; low-molecular-weight polyisobutene: 10-15 parts parts; antioxidant: 0.5-1 part; glass fiber: 5-10 parts; silicate: 5-10 parts;

[0021] S2. Blending: After the kneading is completed, add inorganic fillers for blending. The blending time is 30-50 minutes, the temperature is 120-160°C, and the blending speed is 200-280rpm. Calculated by weight, inorganic fillers: 10-15 share;

[0022] S3. Extrusion: Extrude the blende...

Abstract

The present invention discloses an optical fiber surface coating adhesive preparation method which comprises the following steps: S1. kneading, to be more specific, high molecular weight polyisobutylene, organic silicon rubber, medium molecular weight polyisobutylene, low molecular weight polyisobutylene, an antioxidant, glass fibers and silicates are added in a rubber kneading machine for kneading, the kneading time is 30 to 50 minutes, the temperature is 120-160 DEG C; S2. mixing, to be more specific, after the completion of the kneading, an inorganic filler is added for mixing, the mixing time is 30 to 50 minutes, the temperature is 120-160 DEG C, the mixing speed is 200-280rpm; S3. extrusion, the mixed plastic material is extruded into a rubber extruder through a discharging screw, then is extruded from the rubber extruder to coat the optical fiber surface, wherein the extruder machine barrel temperature is 100-150 DEG C, and the machine head temperature is 120-140 DEG C.

Description

technical field [0001] The invention relates to an optical cable structure, in particular to a method for preparing an optical fiber surface coating glue. Background technique [0002] Optical cable is a light transmission tool that achieves the principle of total reflection of light in fibers made of glass or plastic. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. In the prior art, the optical fiber is arranged in the loose tube, and at the same time, fiber paste is added to the loose tube. The fiber paste is indispensable in the production of central tube type and layer-stranded optical cables, and plays a role of sealing, stress resistance and buffering function, but it does not have the effect of heat insulation; in the prior art, in order to combine the optical fiber and the tr...
