Abstract

The invention discloses an environment-friendly optical cable splice box sealant and a preparation method thereof, belonging to the technical field of sealant preparation. The sealant is composed of silicone rubber, flame retardant, butyl rubber, medium molecular weight polyisobutylene, low molecular weight polyisobutylene, anti- Oxidant composition, its preparation method comprises the following steps: S1. Weighing: Weigh raw materials, set aside; S2. Kneading: Add raw materials for kneading; S3. After the rubber material is extruded, it is cooled and cut to obtain an environmentally friendly sealant. The sealant of the present invention has excellent adhesion, flame retardancy, filling, sealing, water resistance, high and low temperature resistance, acid resistance, alkali resistance, salt resistance, dielectric properties, and its preparation material does not contain The method is solvent-free, halogen-free, environmentally friendly, and the preparation method has the characteristics of simple production process, time-saving and energy-saving, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of sealant preparation, and in particular relates to an environmental-friendly optical cable joint box sealant and a preparation method thereof. Background technique [0002] With the rapid development of my country's industrialization in recent years, the business demand for communication systems, monitoring, and control has increased rapidly, and the use of optical fiber cables instead of copper cables as a means of information transmission has gradually shown huge technical potential. But at the same time, with the frequent occurrence of various accidents and disasters, optical cables and cables often play the role of fuse, causing the fire to spread rapidly and damage valuable electronic instruments and equipment, affecting the normal operation of the entire line or even paralyzing. Thereby expanding the loss of the disaster. [0003] In communication cable and optical cable joint equipment, such as col...
